At present, sanitary napkins are favored by women because of their softness, cleanness, strong hygroscopicity and convenience. Therefore, the production and consumption of sanitary napkins also show a rapid upward trend. This paper briefly explains the problems of PE film packaging for sanitary napkins, and puts forward the improvement methods for the problems of PE pouch film.

1.Problems in PE film packaging of sanitary napkins

The sanitary napkins on the market are basically sold in a single package, and each piece of sanitary napkin is packaged independently through PE film packaging. Independently packaged sanitary napkins, including sanitary napkin body, PE film packaging covered on the outside of the sanitary napkin and release paper adhered with it and covered on the back glue of the sanitary napkin bottom film.

Because the existing PE film packaging used in the sanitary napkin body for independent packaging is made of plastic paper that can be pasted. If the film is directly pasted on the back glue of the sanitary napkin bottom film, it is difficult to tear off the film. When users use or change sanitary napkins, they need to take out a piece of independently packaged sanitary napkin from the packaging bag and tear off the film and release paper before using. There are some shortcomings and defects in the production and use of this film: first, when women use or change sanitary napkins, the film and release paper will be thrown away, polluting the environment; Secondly, when women use or change sanitary napkins, they usually need to wipe the used parts, while the existing sanitary napkins are not equipped with paper towels. At the same time, the film and release paper can not be used as paper towels, which brings inconvenience to users.

2.Improvement methods for problems in PE film packaging

First of all, it is clear that the problem we need to solve is to eliminate the separation of paper. At the same time, PE film packaging, which independently packs sanitary napkins, has the dual functions of release paper and paper towel, reducing environmental pollution and saving production and use costs.

In order to solve this problem, this improved method can be adopted: make a PE film packaging for an independent sanitary napkin, which is composed of an adhesive layer and a soft paper layer, and the adhesive layer and the soft paper layer are connected together through adhesive. The soft paper layer has at least two layers.

Compared with the past, this method has the following advantages:

1.There are adhesive layer and soft paper layer. When using, PE film packaging covers the sanitary napkin, and the adhesive layer of the film contacts with the bottom film of the sanitary napkin. Because the adhesive layer has the function of release paper, producers can save release paper when packaging sanitary napkins, save production costs and reduce environmental pollution.

2.When the user is using or changing the sanitary napkin, remove the film covering the sanitary napkin. Since the soft paper layer of the film has the function of paper towel, users can directly wipe the use part with the film without carrying paper towel, which is convenient to use.

With the development of modern society, women's health awareness is gradually enhanced, and the use of sanitary napkins is becoming more and more common. As one of the raw materials of sanitary napkins, PE film packaging has attracted more and more attention. Understanding the existing problems and improvement methods of PE pouch film is conducive to the better development of sanitary napkins and serving women.
