The difference between plastic film and adhesive tape
POF has the characteristics of high gloss, good toughness, high tear resistance, uniform heat shrinkage and suitable for automatic high speed packaging. It is the traditional PVCReplacement product. BOPP is the abbreviation of "Biaxially Oriented Polypropylene". BOPP film is biaxially oriented polypropylene film.
There are several kinds of plastic film, PEPOFPVC, tape is BOPP, brush gluePE: polyethylene, which is joined by a repeating - CH2 - unit. Polyethylene is formed by addition polymerization of ethylene (CH2=CH2), and POF isPOF full name coextrusionYes, it willAs an intermediate layer (LLDPE), a total of(PP) as internal and external, through three unitsPlastic extrusion, and then through the mold forming, bubble blowing and other special processes.
BOPP film is the production of polypropylene polymer melt is made first by a narrow nose or thick sheet, then stretched in a dedicated machine, at a certain temperature and speed setting, at the same time or step by step in two perpendicular directions (vertical and horizontal) on the stretch, and after appropriate cooling or heat treatment or special processing (such as corona and coating) made of thin film.BOPP films commonly used include: ordinary biaxially oriented polypropylene film, heat sealing BOPP film, cigarette packaging film, BOPP BOPP pearl film, metal film, Matt Film etc..
