BOPP film data --

BOPP is an abbreviation for "Biaxially Oriented Polypropylene", which is a biaxially oriented polypropylene film.
The BOPP film is produced by first forming a melt of high molecular polypropylene into a sheet or a thick film through a narrow machine head, and then simultaneously or stepping at a certain temperature and a set speed in a dedicated stretching machine. A film that is stretched in two perpendicular directions (longitudinal, transverse) and subjected to appropriate cooling or heat treatment or special processing (such as corona, coating, etc.).
Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealed biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented polypropylene pearl film, biaxially oriented polypropylene metallized film, matte film, and the like.

Production considerations
In order to obtain better comprehensive performance, it is usually produced by a multi-layer composite method in the production process. BOPP can be combined with a variety of different materials to meet specific application needs. For example, BOPP can be combined with LDPE (CPP), PE, PT, PO, PVA, etc. to obtain high gas barrier, moisture resistance, transparency, high temperature, low temperature, retort resistance and oil resistance. Different composite membranes can be applied to oily foods and precious tastes. Food, dry food, impregnated food, various cooked foods, monosodium glutamate, pancakes, rice cakes, etc.
From usage points:
Matting film---BOPP+ matting powder, product packaging for matting effect
Pearlescent film---BOPP+ pearl powder, used for pearlescent effect packaging, also has other materials of pearlescent film.

Advantages of BOPP film:
BOPP film is a very important flexible packaging material. BOPP film is colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.
BOPP film has low surface energy and needs corona treatment before coating or printing. After corona treatment, the BOPP film has good printing adaptability, can be printed in color, and has a beautiful appearance effect, and thus is often used as a surface layer material of the composite film.
Insufficient BOPP film:
BOPP films are also insufficient, such as easy accumulation of static electricity, no heat sealability, and the like. In high-speed production lines, BOPP film is prone to static electricity, and an electrostatic remover is required. In order to obtain a heat-sealable BOPP film, a heat-sealable resin glue such as PVDC latex, EVA latex, etc. may be applied after corona treatment on the surface of the BOPP film, or a solvent glue may be applied, or extrusion coating or The co-extruded composite method produces a heat sealable BOPP film. The film is widely used in the packaging of bread, clothes, shoes and socks, as well as the cover of cigarettes and books. The initial tear strength of the BOPP film is improved after stretching, but the secondary tear strength is very low. Therefore, no cuts can be left on both end faces of the BOPP film, otherwise the BOPP film is easily torn during printing and compounding. BOPP can produce sealing tape after coating self-adhesive, which is a market with a large amount of BOPP.
