Cosmetic packaging bags mostly use composite film materials. By combining the characteristics of different materials, the best effect can be achieved. Common structures include:
PET/AL/PE: Polyester/Aluminum Foil/Polyethylene combination. The aluminum foil offers excellent protection against light, oxygen, and moisture, and is commonly used in the packaging of high-end creams and serums.
BOPP/VMAT/PE: Biaxially Oriented Polypropylene/Glassine Silvered Film/Polyethylene combination. The metallic effect gives the packaging a luxurious visual texture, and is often used for facial masks and cosmetic product packaging.
KNY/PE: Polyamide Nylon/Polyethylene combination. It has good puncture resistance and flexibility, and is suitable for packaging items with sharp edges (such as makeup brushes).
Transparent high-barrier structure: such as PET/EVOH/PE, it provides good barrier properties while remaining transparent, meeting consumers' psychological need of "what you see is what you get".
The packaging bags of beauty products are widely used in the following areas due to their characteristics such as lightness, flexibility and relatively low cost:
Product trial and promotion: Many brands use small self-contained bags, flat bags, etc. as trial or promotional packaging for products such as serums, lotions, shampoos, etc. This small-capacity packaging reduces the trial cost for consumers and helps with new product promotion.
Disposable products: For example, disposable shampoo, body wash, hair conditioner (common in hotels or travel scenarios), and single-portion masks. These packages are lightweight and sealed, making them convenient to carry.
Supplementary packaging: To promote environmental protection, many brands provide bagged replacement cores to replenish the main packaging bottles or cans. This can effectively reduce plastic usage.
Packaging for specific categories: Standing suction nozzle bags, due to their ease of pouring and resealing, have also gradually been applied to the packaging of some products such as lotions, serums, and hair creams.
