The most suitable packaging materials for creams

 Jars：

Glass Jar (Heavy, Luxury, and Temperature-Resistant)

Glass Jar come in a variety of formats, including jars, bottles, and vials, making them ideal for products requiring the utmost purity. Amber or frosted glass variants offer UV protection, protecting light-sensitive ingredients like retinol or vitamin C from degradation.

Plastics Jar (such as PETG, ABS, and PP, which are lightweight and easy to process) are widely valued for their durability and cost-effectiveness. High-density polyethylene (HDPE) and polypropylene (PP) are common choices, offering chemical resistance and lightweight advantages. Plastic jars with screw-top lids are suitable for body butters and thicker lotions.

Features: Classic and traditional, easy to use, and easy to show the paste texture and color. However, the contents are frequently in contact with air and fingers, which requires a high level of antiseptic system.

Applicable to: Luxurious nourishing facial creams, sleeping masks, massage creams, neck creams and other products that do not require extremely precise rituals and dosages.

Tubes：

Aluminum tubes (with an epoxy or phenolic interior coating) excel in this regard: their impermeable barrier seals out moisture and air, preventing degradation of active ingredients. The squeezable tube design allows users to dispense small, targeted amounts, reducing waste and ensuring precise application. Aluminum tubes seal tightly after each use, minimizing pollution. Aluminum is recyclable, making it attractive to environmentally conscious consumers.

Plastic composite tubes (e.g., PE/EVOH/PE, with high barrier properties). Plastic tubes with flip-top caps are ideal for travel-sized face creams. Advanced plastic formulations, such as those with barrier coatings, now rival glass in terms of moisture and oxidation resistance.

Features: Excellent sealing, strong barrier properties (light-proof and anti-oxidation), lightweight and easy to carry, and a squeeze-type dispenser allows for hygienic and precise dosage control. The aluminum tube has a retro, cosmeceutical, and pure feel.

Applicable to: Day cream, night cream, hand cream, ointment, and other products requiring high hygiene standards.

Airless Pumps Jar：

Features: Utilizing the air pressure principle, the device allows for "outflow only, no inflow" to completely isolate the contents from air and bacteria, significantly protecting the freshness of the active ingredients. It's clean and hygienic, leaving virtually no residue and providing an excellent user experience.

Applicable to: Almost all high-end functional skin care products, especially those with extremely high requirements for ingredient activity.

Lotion Pumps bottle：

Material: Bottles are typically made of plastic or glass with a pump.

Features: Easy and quick dispensing, controlled dosage, and superior hygiene compared to wide-mouth bottles. However, this product may leave residue and come into contact with the air at the top of the bottle.

Useful for: Thinner lotions, moisturizers, body lotions, etc.

How to Clean Dropper Bottles Yourself A Simple 4-Step Guide

Cleaning cosmetic glass dropper bottles properly is key to keeping your serums, essential oils, and liquids free from contamination. Follow this quick 4-step process to ensure they’re spotless and safe for reuse.​
First, disassemble the glass dropper bottle—separate the rubber bulb, glass pipette, and bottle itself. Fill a bowl with warm (not hot) water and let all parts soak for 10–15 minutes. This loosens residue, oils, or dried liquids clinging to the surfaces, making them easier to clean.​
Next, disinfect with rubbing alcohol (70% isopropyl works best). Either submerge all components in alcohol for 5 minutes, or pour alcohol into the bottle and squeeze the bulb repeatedly to flush the tube thoroughly. Alcohol effectively kills bacteria and breaks down tough, stubborn grime that plain water would likely leave behind.​
After alcohol treatment, rinse all components with warm water to remove any alcohol residue. Then, air-dry them completely on a clean towel—laying them upside down helps speed up drying and prevents moisture buildup, which can lead to mold.​
For an extra layer of sanitization, use an infrared ozone sterilizer. Place the dry parts inside, run the machine according to its instructions (usually 10–20 minutes), and let it complete the cycle. Ozone and infrared light work together to eliminate even the tiniest pathogens, ensuring your dropper bottles are germ-free and ready for their next use.​
This straightforward routine keeps your dropper bottles in top shape, protecting your products and extending the life of your containers.

The All-Scenario Revolution of Period Panties Comfort, Leakproof, and Sustainability Leading Women’s Underwear Trends

 

Over the past years, menstrual underwear—also known as period panties—has evolved from a niche eco-friendly alternative to one of the fastest-growing segments in the global women’s lingerie market. In 2024, the global market value neared USD 680 million, with projections to surpass USD 1.5 billion by 2030, achieving a compound annual growth rate of 13% to 15%. Behind these numbers lies a growing awareness of women’s health, the rise of sustainable consumption, and continuous innovation in design and technology. Periods are no longer times to endure discomfort but moments that demand comfort, confidence, and self-care.

As the global Period Underwear OEM Suppliers and Wholesale market experiences rapid growth, more brands and distributors are recognizing the potential of this emerging segment. This has sparked a surge in demand not only from end consumers but also from businesses looking to capitalize on new market opportunities.

This shift first manifests in the most direct consumer needs: leak protection and comfort. Early menstrual underwear was viewed mainly as a supplement to disposable products, but increasingly women use it as their primary protection. Advances in leakproof technology are key: premium period panties feature organic cotton or bamboo fiber inner layers for fast absorption, super-absorbent cores locking in moisture, and waterproof, breathable outer layers. High-waist styles with extended back panels offer comprehensive security for overnight and heavy flow users. These functional innovations meet core period needs and lay the foundation for further product development.

Once leakproof concerns are addressed, comfort becomes the critical factor driving repeat purchases. Modern women continue to work long hours, exercise, and travel even during their periods, fueling demand for seamless period panties and high-stretch fabrics. These designs maintain a stable fit without rolling, shifting, or causing heat buildup. Brands are segmenting their offerings by scenario: commuter styles prioritize stability and invisibility, athletic styles emphasize elasticity and support, and nighttime versions focus on softness and high absorbency.

 

Beyond function, sustainability is reshaping the market. Reusable menstrual underwear significantly reduces waste compared to disposables, appealing to eco-conscious consumers. Certifications such as GOTS organic cotton and GRS recycled fibers have become core brand selling points and contribute to premium pricing. Sustainability is no longer a “nice-to-have” but a decisive factor influencing purchase decisions.

 

Expanding Multi-Scenario Applications Unlock Massive Market Potential

As consumers demand higher health and lifestyle standards, the use cases for period panties have expanded well beyond traditional menstrual protection. This category is rapidly evolving into a multi-functional, multi-purpose product, unlocking enormous market potential.

 

First is the postpartum recovery period. New mothers face extended discharge and intimate care needs. Traditional pads often cause discomfort and require frequent changes. Soft, highly absorbent menstrual underwear is an ideal solution, offering effective protection while minimizing skin irritation and improving comfort.

 

Next is light urinary leakage protection. With age or after childbirth, pelvic floor weakening leads to common minor leakage issues. Specialized leakproof underwear with high absorption and antibacterial fabrics helps women confidently manage daily challenges, significantly broadening the user base.

 

Third, the sports and fitness scenario. Many women worry about leaks during running, yoga, or gym workouts. High-stretch, seamless, quick-dry period panties have become the go-to choice for active women, combining leak protection with freedom of movement and comfort during intense exercise.

 

Additionally, travel and outdoor activities form another important application field. Disposable products are inconvenient to carry and dispose of, while quick-dry, easy-to-clean period panties provide an eco-friendly and practical alternative, meeting the needs of long trips and outdoor enthusiasts.

 

Bulk seamless period panties supplier

 

This cross-scenario functionality not only increases usage frequency but also shifts consumer perception of period panties from “menstrual protection” to “all-year-round functional underwear.” Brands are responding by developing richer product lines, expanding market space and growth opportunities.

 

The competitive landscape is currently divided into three main players. International leaders like Thinx and Modibodi have established global presence through premium design and sustainability narratives; regional brands such as NEIWAI and Bananain quickly capture younger markets by blending local aesthetics with functional innovation; meanwhile, numerous OEM & ODM Period Panties Manufacturers play a crucial role in the global supply chain, providing affordable entry points for emerging brands. Differentiated functional designs, unique aesthetic positioning, and sustainability credentials are key strategies for new entrants.

 

Looking ahead 5 to 10 years, menstrual underwear technology will trend toward thinner, faster-drying, and higher-efficiency absorption. Nano-fiber technologies are expected to significantly enhance comfort and dryness. The demographic will expand from the core 18–35 female group to include teenagers and older women. Cross-category integration will become more common, merging period panties with sports bras, swimwear, and protective underwear to create multifunctional garments. On the distribution side, Direct-to-Consumer (DTC) brands will leverage social media platforms like TikTok and Instagram to accelerate global expansion. For brands and wholesalers alike, 2025 to 2030 represents a golden window of opportunity to capture market share and innovate in this rapidly evolving industry.

Price of Tinplate is Going High

Yarlung Tsangpo River hydropower project as a major national infrastructure projects, if the full start, may indeed have a phased impact on the steel industry.

The main material of empty aerosol tin can is tinplate, now the price of tinplate will be increased, we have to adjust the price of our cans.
Please let us know if you have any plan, we can prepare the material in advance.


Guangdong Sihai Iron-Printing & Tin-Making Co., Ltd. was founded in 1998, located in the beautiful tourist city of Zengcheng, Guangzhou. Our company covers an area of 38,000 square meters and our main business is tinplate trading, coil cutting, coating, printing and tin-making.


What physical tests does the tube packaging have to undergo?

1.Thickness measurement

The precise thickness of each layer of a tube is fundamental to its performance. This test uses a micrometer or specialized thickness gauge to measure the actual thickness of each layer (from the inner barrier film to the outer printed layer), typically at five to ten points throughout the tube. The goal is to ensure compliance with design specifications.

2.Sealing performance test

Heat Seal Strength (Tube End): Tube ends are sealed using heat during the manufacturing process. This test measures the force required to tear the seal. It ensures that the seal will not crack during extrusion, transportation, and storage. Standards generally require a minimum strength to ensure reliability.

Torque Test (Tube End to Cap): This test evaluates the tightness of the connection between the tube end and the cap. A torque meter measures the force required to unscrew or tighten the cap, ensuring it is neither too loose nor too tight. Typical ranges vary depending on product type—cosmetic tubes may require 0.5-1.5 Nm.Positive/Negative Pressure Test: To simulate extreme conditions, the tube is subjected to positive or negative pressure in the seal. This can identify micro-leakages in the seal that may be missed by standard visual inspection.

3.Barrier performance test

Barrier performance is crucial for products susceptible to external influences like oxygen and light. 

Two key test types dominate this category:

Oxygen Transmission Rate (OTR): According to the standard, this test measures the amount of oxygen that passes through the tubing material over time. A low OTR is crucial for products like vitamin C serums or essential oils, as oxidation can reduce their effectiveness.

Water Vapor Transmission Rate (WVTR): According to the standard, this test quantifies the amount of moisture that migrates through the tubing. This is crucial for dry products (such as powdered skincare) or water-sensitive formulas, as excessive moisture can lead to clumping or microbial growth.

4.Mechanical strength testing

Compression resistance: This test simulates warehouse stacking, placing the hose under pressure for a week. This checks for deformation, collapse, or seal failure under sustained load.

Drop test: Tubes (empty and full) are dropped from various heights (e.g., 1 meter, 1.5 meters) and at various angles (vertical, horizontal, diagonal) to simulate an accidental drop. This test ensures there are no cracks, leaks, or cap detachments.

Flex resistance: The tube is repeatedly flexed, particularly at the shoulder (where the barrel meets the nozzle), until it breaks, typically over 10,000 cycles. This test assesses the durability of travel-sized hoses or products designed for portable use.

5.Extrusion performance testing

You know what? A user's experience with a product is largely tied to how easy it is to squeeze the stuff out and how clean the whole process is.Take those squeeze tests, for example. We use something called a texture analyzer to measure just how much force is needed to get the product out of the tube. The goal here is to make sure it's not a total nightmare to squeeze (because who wants to get all frustrated, right?). But at the same time, it shouldn't be so easy that you end up squirting out way more than you need.And it doesn't stop there. The testers also keep an eye out for issues like "rat tails." You know, those stringy bits that hang around after you've squeezed the tube? Or problems with uneven flow. These little things might seem minor, but they can lead to a whole lot of wasted product and just a generally crummy experience for the user.Now, when it comes to medicine tubes where you need to get the exact right dose every single time, things get even more serious. The consistency of how much comes out with each squeeze is checked super carefully.

Should Vitamin C Serums Be Stored in Dark Glass Bottles? Why Not Plastic?

The Delicate Nature of Vitamin C

Vitamin C, also known as ascorbic acid, is a powerhouse ingredient in skincare, renowned for its antioxidant properties, ability to brighten the complexion, and stimulate collagen production.However, it's also a highly unstable compound. It's extremely sensitive to light, air, and heat.Once exposed to this substance, vitamin C will be quickly destroyed, lose its efficacy and become useless. Such decline not only prevents you from enjoying all the benefits brought by the essence, but may also cause side effects and skin discomfort.

 

The Advantages of Dark Glass Bottles

Dark glass bottle (usually amber or brown in colour) act as a shield for Vitamin C serum. The dark glass bottle acts as a natural filter, blocking most ultraviolet (UV) and visible light. This helps to slow down the oxidation process that occurs when vitamin C is exposed to light, thus maintaining the stability and potency of the serum longer. In addition, glass is an impermeable material, which means it is difficult for air to pass through. This better prevents Vitamin C from being oxidised by atmospheric oxygen, which ensures that each product remains undamaged until your end use.

 

The Drawbacks of Plastic Bottles

In contrast, plastic has several disadvantages when it comes to storing vitamin C serum. Firstly, plastic is usually more transparent to light than dark coloured glass. Even though this plastic bottle is tinted, it still allows more light to pass through, which can speed up the breakdown of vitamin c. Secondly, plastic is a porous material. Over time, air can slowly seep into the bottle through the small holes in the plastic, causing the serum to oxidise. Additionally, some types of plastic may contain chemicals that can leach into the product, potentially causing skin reactions or altering the ingredients of the formula.

Why do skin care products tend to change color in glass bottles?

Contents change color or evaporate? Is the barrier property of the glass bottle not good enough?

Many customers have reported problems such as discoloration, abnormal odor, and decreased concentration of skin care products during product sales or use. This is especially true for skin care formulas containing essential oils, active ingredients, or natural plant extracts. In other words, during product sales or daily use, consumers often report that skin care products have changed color; some products emit abnormal odors, which not only affects the user experience, but may also have an adverse effect on skin health; and some customers have found that the concentration has decreased after use, which undoubtedly reduces the effectiveness of the product.

 

Cause analysis

These problems are often closely related to the poor light-blocking ability and airtightness of glass bottles. Although transparent glass has a good visual effect, it is easy for external factors such as ultraviolet rays, oxygen, and water vapor to affect the stability of the contents when exposed to strong light, temperature fluctuations, or repeated opening and closing. In addition, if the bottle mouth sealing structure is not designed properly, it will also accelerate the contact between the contents and the air, causing the components to degrade or volatilize.

 

Solution

1. Choose dark glass bottles: Using brown, green or black glass bottles can significantly reduce UV penetration and effectively delay the oxidation and deterioration of products.

2. Spray the inner film on the bottle: By spraying a chemically stable coating on the inner wall, the glass can enhance its ability to isolate the contents, prevent the components from being adsorbed on the bottle wall or reacting with the glass in trace amounts, thereby extending the shelf life of the product.

3. Use vacuum pump bottles or airtight dropper bottles: The vacuum structure design can reduce air residue during filling and prevent external air from flowing back during use, which is particularly suitable for packaging highly active skin care products such as essence skin care products.

4. Optimize the bottle mouth sealing structure design: Add a variety of sealing structures such as sealing gaskets, precision screw caps and closed sleeves to improve the overall air tightness, effectively block the entry of air and water vapor, and avoid the volatilization and contamination of internal substances.

4 ways to solve glass bottle damage during transportation

In the skin care industry, glass bottle packaging is widely used in high-value-added products such as essences, creams, lotions, and facial oils due to its high-end texture, excellent chemical stability (strong barrier properties and good sealing properties) and environmentally friendly properties. These characteristics make it an ideal choice for enhancing product image and ensuring quality. However, brands or buyers often face a series of specific problems in the process of transporting glass packaging materials, which may affect the final product experience and brand image.

Problem manifestations:

1. During the process of receiving, transporting (especially international transport) or filling, the bottle body is broken, shattered, cracked, corners are broken, and the edge of the bottle mouth is broken.

2. It leads to high loss rate, affecting cost and product availability.

Main reasons:

1. Insufficient bottle material and strength: The glass is too brittle, and high borosilicate glass, high-strength soda-lime glass or annealed reinforced/thick-walled glass are not selected.

2. Bottle structure design defects: The bottom of the bottle is too thin or the structure is unreasonable, and the pressure and impact resistance are poor.

3. Insufficient packaging protection: The outer box and inner packaging (such as inner tray, cushion) fail to provide effective buffering. There is a lack of sufficient shockproof structure (such as foam cotton, pearl cotton, honeycomb paper tray, partition board) to resist vibration, impact and extrusion during logistics.

4. Improper transportation plan: Failure to adopt optimized palletizing and transportation plans (such as customized pallets, reinforced cartons).

cosmetic dropper packaging

Comprehensive solution:

1. Improve the strength of the bottle:

Choose high borosilicate glass or high-strength soda-lime glass;Use annealed glass.Thicken the bottle wall, especially optimize the bottom structure and thickness distribution, and enhance the pressure resistance and impact resistance. Choose a thick bottom pressure-resistant design.

2. Strengthen packaging protection:

Use customized high-strength outer boxes.Fill the interior with sufficient cushioning materials: such as customized honeycomb paper inner tray/paper box, foam inner tray, pearl cotton/foam cotton cushion, and partition.The packaging structure must pass the drop and pressure resistance tests.

3. Optimize transportation and testing processes:

Conduct small batch sample transportation tests to simulate the actual logistics environment, and continuously optimize the packaging design based on the test results.Use more stable transportation solutions such as customized pallets and reinforced carton palletizing.Select experienced and reliable glass bottle suppliers.

4. Risk management:

Require suppliers to implement strict factory inspection processes (including appearance, strength, etc.).Negotiate with suppliers on damaged reissue terms to reduce procurement risks.
