Mask bag packaging is one of the main packaging forms of mask products in the market today. With the improvement of people's living standards and people's attention to their own skin problems, the market demand for facial mask bags is increasing.

At present, most of the common facial mask bags on the market are made of aluminum foil or aluminum-plated materials. The aluminum foil facial mask bags give consumers the impression that, in addition to excellent packaging performance, it is intuitive to reflect the texture.

Of course, the use of aluminum foil bags in the mask packaging can also extend the shelf life of the packaging mask. Most facial masks have a shelf life of more than 12 months or even 36 months. In order to obtain such a long shelf life, the basic requirements of the mask packaging bag are the tightness and high barrier properties of the packaging. In view of the consumption characteristics and shelf life requirements of the mask itself, the material structure and production process requirements of the mask packaging bag are basically determined.

Although the material structure and production process requirements of the film bags on the market are similar, in actual production, there will always be various production quality problems. These problems can be divided into two aspects: the uniformity of the surface of the mask bag and the flatness of the surface of the mask bag degree.

Specifically, the quality problems of the end face uniformity of the mask bag can be divided into the cutting edge and the aluminum particles on the end face. Therefore, in the production of mask bags, strict attention must be paid to whether the knives are flat or defective; if the knives are uneven, the knives must be polished and adjusted before production to avoid the above-mentioned quality problems during the production of mask bags.

However, the quality problems of the surface smoothness of the mask bag can be reflected in the indentation, streaks and scratches on the surface of the mask bag. These problems are mainly caused by foreign matter on the guide roller or the driving roller; or the tripod position is not flat and the guide roller is not flat. It is flat; however, most of the scratches on the surface of the bag occur in the transmission part, so it is necessary to find an effective starting point for the scratches.

Although the production of facial mask bags may have large or small quality problems, as long as the machine is adjusted properly, the 5S work is done well, and the production is strictly controlled, the above quality problems can still be avoided or handled in time.
