Polypropylene film manufacturing method
Polypropylene film can be divided into the following according to the different manufacturing methods
1) T-type head extrusion casting method, such as the production of polypropylene cast film.
2) A bubble tube method, such as a polypropylene blown film.
3) Stretching method, the film blank produced by the above two methods, or the co-extrusion blown film or the co-extruded cast film blank described later, and then made by uniaxial stretching or biaxial stretching, biaxially stretching The propylene film is abbreviated as BOPP, the uniaxially stretched polypropylene film is referred to as MOPP, and the stretched film is collectively referred to as OPP. BOPP has a large output and is widely used. In the case of no name, OPP is mostly BOPP. This book only covers its performance and use.
4) The composite method, the polypropylene and other resins are co-extruded or co-extruded into a polypropylene composite film, or by extrusion coating or dry compounding.
5) The secondary processing method further processes the polypropylene film, and vacuum-aluminized polypropylene film is typically formed by vacuum aluminum plating.
6) Other special processing methods, such as the production of micro-films by stretching or other methods of polypropylene film blanks, or other methods to obtain special performance films. With a variety of packaging applications, a variety of versatile high value-added films can be produced by coating, composite film, polymer blending surface treatment, etc., or by secondary processing to produce high-grade Packaging material.
