It is self-evident how important the film packaging bag is to the mask. Compared with the fancy decoration on the surface, the storage and protection functions of the mask packaging bag are actually more important.

High-end facial masks have become a trend. In addition to showing excellent performance and texture on aluminum foil packaging bags, there is also a shelf life. Most facial masks have a shelf life of more than 12 months, and some even 36 months. With such a long shelf life, the most basic requirements for packaging bags are: tightness and high barrier properties.

Analyzing from the raw material itself, the general mask packaging bags are mainly divided into two types: aluminized bags and aluminum foil bags. The aluminum-plated bag is to coat high-purity metal aluminum uniformly on the plastic film under high-temperature vacuum state. The aluminum foil bag is made of pure metal aluminum sheet and is combined with the plastic film to improve the plastic's barrier properties, sealing properties, fragrance retention, shielding properties and other functions.

From the perspective of the main material structure, aluminized film and aluminum foil film are basically used in the packaging structure.

Compared with aluminum plating, aluminum foil has a good metallic texture, which is silvery white and has anti-gloss properties; aluminum has soft characteristics, and products with different composite materials and thicknesses can be customized according to requirements, which meets the pursuit of high-end products for heavy textures. The packaging is more intuitive. There will be no deterioration due to changes in the external environment, and packaging bags made of this material can be used without worrying about chemical reactions between the mask and the material.

The aluminum foil bag has better stability. As usual, many substances are added to the mask. If the packing material is not stable, it will chemically react with these substances over time, which will lead to deterioration of the mask.

Nowadays, many facial masks are transported remotely when they are sold, and then they can be delivered to the sales location. In the long-term transportation process, the outside temperature and light will undergo many changes. In order to improve the storage time of the mask, it is necessary to choose Pack the mask in aluminum foil bag. Since the aluminum foil bag will not be affected by the surrounding temperature and humidity, it can ensure that the mask is safer during transportation. Having introduced so much, I believe you already have an understanding of the choice of mask bags!
