Brief introduction

Our company specializes in the production and sales of three-sided cover film bags. The conventional mask bags will use aluminum foil composite structure to create a smooth and crisp effect. The square packaging bags are generally between 150mm-160mm, and the rectangular size is about 140mm*170mm. According to the design, the four corners are rounded (the effect of the rounded corners reduces the sharpness and increases the roundness). In addition, there are some irregular packaging bags. These various types of mask bags have added a die-cutting process in the production process, so the finished packaging bags are already in the shape of the design.
Analyzing from the raw material itself, the general mask packaging bags are mainly divided into two types: aluminized bags and pure aluminum bags. The aluminum-plated bag is to coat high-purity metal aluminum evenly on the plastic film under high-temperature vacuum. The pure aluminum bag is formed by the extension of pure metal aluminum sheet, and is compounded with the plastic film to improve the plastic’s barrier properties, sealing properties, fragrance retention, shielding and other functions. In other words, pure aluminum facial mask bags are more suitable for the market requirements of mask packaging bags.
