Machines in this series are suitable for reel-shape materials such as BOPP, PET, CPP, luminum foil, and paper, 2-layer repetitious laminating, high strength production, producing high-quality compound materials with high freshness preserving, and boiling & steaming resistance.
BOPP is a simple version of Biaxially Oriented Polypropylene
Said, bopp tape sealing tape, transparent sealing tape, printing tape, color sealing tape, packaging tape is biaxially oriented polypropylene film.
It is produced by first making a melt of high molecular polypropylene into a sheet or a thick film through a narrow machine head, and then simultaneously or stepwise in a dedicated stretching machine at a certain temperature and set speed. A film made by stretching in both 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. The performance parameters and main uses of the various films are as follows:
Ordinary BOPP film
Uses: Mainly used for printing, bag making, adhesive tape and compounding with other substrates.
Performance: * High transparency and gloss * Excellent ink and coating
Water vapor and grease barrier properties with excellent adhesion * Low electrostatic performance Common thickness: 15, 19, 20, 25, 28, 35, 38, 40, 45jim
