BOPET Heat Sealable Film for Cosmetics Packaging

When Jincheng manufacturer produces this BOPET Heat Sealable Film for Cosmetics Packaging, it overcomes the shortcomings of ordinary heat-sealable films, such as easy air leakage, easy edge lifting, and easy peeling. Instead, it adopts modified heat-sealing formula to create a high-strength and non-peelable sealing structure. The seal is tight and stable, eliminating problems such as powder leakage during transportation, moisture absorption, loss of fragrance, and dust contamination of cosmetics.

Product Core Details

1. Precise graded thickness, compatible with all categories of cosmetic packaging

2. Dual-sided precise corona treatment, suitable for cosmetic color printing customization

3. Dual-profile differentiated structure, balancing appearance level and protection

4. Wide-range stable heat sealing process, compatible with daily care mass production equipment

5. Unbreakable exclusive feature, preventing cosmetic packaging from being damaged or losing materials

Why is it suitable for cosmetic packaging scenarios?

Cosmetics often contain fragrances, essential oils, and active photosensitive components, which are prone to moisture absorption, evaporation, oxidation and deterioration. This BOPET Heat Sealable Film for Cosmetics Packaging has excellent sealing performance, effectively preventing dust, moisture, and air from invading, firmly locking in the product's fragrance and active ingredients, preventing cosmetic products from developing odors, clumping, or deterioration over time, significantly extending the shelf life of the products, and meeting the packaging requirements for skincare products, makeup, and fragrance products.

Relying on the factory's ISO9001, ISO14001, and OHSMS18001 full set of system certifications, the entire production process is dust-free control and free of harmful chemical emissions. The material is safe and stable, meeting the compliance requirements for cosmetic packaging. It has no odor, no pollution, and will not undergo chemical reactions with cosmetic raw materials. It is suitable for packaging categories with strict safety requirements such as intimate cleansing products and facial makeup.

E-commerce cosmetic products need to undergo multiple transfers, stacking, and squeezing, which makes the packaging prone to damage and material leakage. This product has high sealing strength and excellent toughness, resisting stretching and bending, and the edge sealing is not prone to cracking and falling off. It can perfectly adapt to the high-frequency circulation scenarios of express delivery logistics, significantly reducing the damage rate during after-sales services and reducing brand losses.

Factory-specific performance tests

1. Uniformity test of heat sealing strength

Carry out batch heat sealing tests in accordance with the QB/T 2358 industry standard. Conduct spot checks on the bonding strength of the sealing edges at multiple points, and the entire process data can be traced. The heat sealing force of the product is uniform, with no local strong or weak deviations. The edge anti-tensile performance is stable, eliminating common problems such as local false sealing, cracking, and edge warping in cosmetic packaging. The consistency of batch products is extremely high.

2. High and low temperature weather resistance sealing stability test

Simulate the storage environment of high temperature, winter low temperature, and temperature difference in indoor conditions, and conduct a 72-hour environmental aging test. After the test, the seal is free from cracking, shrinking, and delamination, and the sealing performance does not deteriorate. It can adapt to different climates in the north and south and the seasonal temperature differences, ensuring the stable storage quality of cosmetics throughout the cycle.

3. Long-term electrostatic adhesion test

Complete the long-term retest of BOPET Heat Sealable Film for Cosmetics Packaging in normal temperature storage for 6 months. The double-sided dynami value attenuation is extremely low. The printing, compounding, and heat sealing adhesion still meet the standards, without ink shedding, film delamination, or heat sealing failure. It is suitable for batch inventory and long-term storage needs of cosmetic brands.

4. Barrier protection performance test (aluminum-coated model specific)

Carry out tests on the water vapor, oxygen permeability, and light transmittance of the aluminum-coated heat sealing film. The coating is dense without pinhole leaks. It can efficiently block ultraviolet rays, moisture, and oxygen, effectively delaying the deterioration of photosensitive and oxidizable cosmetic components, and the freshness protection performance far exceeds that of ordinary transparent heat sealing films.

5. High-speed machine-compatible production test

Connect with the mainstream fully automatic sealing production lines in the cosmetics industry for continuous on-machine testing. The film material moves smoothly, the tension is stable, there is no deviation, no adhesion, the heat sealing response is fast, it is compatible with 24-hour uninterrupted production, the production yield rate is stable and meets the standards, and it is suitable for large-scale production needs of cosmetic factories.
