Spiral paper core making machine / Paper tube bobbin coiling machine for adhesive tapes.
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
