ン生地に貼合わせて使用される。2. Description of the Related Art Conventionally, a film for backing a bag skin material or a film backed and bonded to a flooring material is required to have a property such as texture, waterproofness, and adhesiveness to fabric. Vinyl chloride films have been used.
In particular, when a nylon fabric is used for the bag skin material, a plasticized vinyl chloride film is used by being attached to the nylon fabric via an adhesive.

融張力を有する物性が、優れた加工適性を示していた。[0003] As the plasticized vinyl chloride film for lamination, a vinyl chloride film having a high plasticizer content, specifically, 40 parts by weight of a plasticizer is added to 100 parts by weight of a vinyl chloride resin.
A plasticized vinyl chloride film containing not less than parts by weight is suitably used, and the flexibility of this film becomes a high-grade feel by being attached to a fabric. Furthermore, if the cloth is a woven cloth, water can pass through the cloth, so that the film can provide waterproofness. In addition, when the film was coated with an adhesive, dried, and then bonded to a fabric while being heated to an adhesive activation temperature, physical properties having high melt tension at high temperatures showed excellent processability.

ダイオキシンを発生する等の問題が生じている。[0004] In recent years, however, the problem of environmental pollution has been regarded as important, and the use of plasticized vinyl chloride containing chlorine has been regarded as a problem in all fields. In particular, when incinerating skin material waste such as bags containing vinyl chloride film,
There are problems such as generation of dioxin.

は困難であった。[0005] For this reason, recently, polyolefin resins have attracted attention as a substitute for vinyl chloride. However, unlike a vinyl chloride film, a polyolefin-based resin film has characteristics in which heat resistance suitable for an adhesive processing line and texture of a final product are incompatible, and it has been difficult to achieve both.

が提案されている。To solve this problem, for example, Japanese Patent Application Laid-Open No. 6-927 discloses that a layer mainly composed of a random copolymer of propylene and various α-olefins contains random polypropylene on both sides. Layers are laminated,
A polyolefin-based resin film instead of a vinyl chloride film has been proposed.

して、作業性や品質を損なうという問題点があった。[0007] However, this polyolefin-based resin film was not as flexible and handy as the current products, had low heat resistance, and was inferior in processing characteristics. In order to solve these problems, resins having more flexibility have been studied, but polyolefin resins having flexibility tend to have a low melting point, and can maintain heat resistance in the heat bonding process. However, there has been a problem that the molten resin layer adheres to the transport rolls and impairs workability and quality.

To improve the wettability of the film, a corona treatment may be applied to the film side. When the film becomes sticky due to the corona treatment, an antiblocking agent may be added to the adhesive surface. At this time, if a fatty acid amide-based slip agent is used, the adhesion may be inhibited. Therefore, it is preferable that the use of the slip agent on the bonding surface be avoided as much as possible. When abrasion resistance is required depending on the application, it is preferable to mix a slip agent or an anti-blocking agent on the surface opposite to the adhesive surface. The amount of the slip agent or the anti-blocking agent used is appropriately determined depending on the use.
