1, release film
1,1 Introduction
A release film refers to a film having a separation surface which is not sticky or slightly viscous after contact with a specific material under limited conditions.
Usually, in order to increase the release force of the plastic film, the plastic film is subjected to plasma treatment, or fluorine treatment, or a silicon release agent is applied on the surface of the film material, so that it exhibits for various pressure sensitive adhesives. Extremely light and stable release force. According to the different release force of the release film, the viscosity of the insulation product is different, and the release force is adjusted accordingly, so that it achieves extremely light and stable release force during peeling.

• 1.2 release film classification by substrate:
> PE (polyethylene) release film;
> BOPP (polypropylene) release film;
> PET (polyester) release film.
Classified by release force:
>Ultra-light release liner (<5§)
>Light release release film (5-10g);
> Medium release release film (10-50g);
>Removal release film (50g or more).

Classified by silicone oil coating:
>Ordinary silicone oil release film >Fluorine plastic release film
>Other categories: such as high temperature silicone pressure sensitive adhesive.
Classified by surface color:
A red release film, a yellow release film, a green release film, a blue release film, a white release film, and the like, and a PET release film of various colors.
Classification by substrate surface treatment:
Single-sided release film, double-sided release film, no-free release film.

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.
