русский1. Application
It is widely used in the packaging of food, candy, cigarettes, tea, juice, milk, textiles, etc., and has the reputation of "Packaging Queen". The wide application of BOPP film, the low pollution and the protection of forest natural resources make it a more popular packaging material than paper and polyvinyl chloride (PVC); the manufacturing process is simple and reliable, and the price is reasonable. Stretched polyester (BOPET) film and biaxially oriented nylon (BOPA) film are more commonly used packaging materials. BOPP film can be compounded with other materials with special properties to further improve or improve performance. Commonly used materials include PE film, cast polypropylene (CPP) film, polyvinylidene chloride (PVDC), aluminum film, etc.
2. BOPP
BOPP is the abbreviation of "Biaxially Oriented Polypropylene", that is, biaxially oriented polypropylene film. Its production is to first make a sheet or thick film from a polymer polypropylene melt through a narrow and long machine head, and then in a special stretching machine, at a certain temperature and a set speed, simultaneously or step by step The film is stretched in two vertical directions (longitudinal and transverse) and made by appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).
3. Introduction
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealable biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearlescent film, biaxially oriented polypropylene metallized film, matting film, composite film Book film, laser molded film, anti-counterfeiting film and paper ball film, etc.
4. Scope
This standard specifies the product classification, technical requirements, test methods, inspection rules, signs, packaging, transportation, and storage of heat-sealed biaxially oriented polypropylene film (hereinafter referred to as "film").
