PET film is a kind of comprehensive performance packaging film

The difference and identification of OPP film and PET film.

When we choose self-adhesive label materials, we can often hear PP and OPP for short. Is there any difference between them? What is the difference between OPP film and PET film?

OPP plastic film is a very important flexible packaging material, OPP film colorless, odorless, tasteless, non-toxic, and has high tensile strength, impact strength, rigidity, toughness and good transparency.

OPP film surface energy is low, coating or printing before the need for corona treatment. After corona treatment, OPP film has good printing adaptability, can be color printing and get exquisite appearance effect, so it is commonly used as the surface material of composite film.

PET film is also known as high temperature polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, can be widely used in magnetic recording, photographic materials, electronics, electrical insulation, industrial film, packaging decoration, screen protection, optical level mirror surface protection and other fields. High temperature resistance polyester film model: FBDW (single side matte black) FBSW (double side matte black) high temperature resistance polyester film specification thickness width diameter core diameter 38μm~250μm 500~1080mm 300mm~650mm 76mm (3 "), 152mm (6 ") Note: Width specifications can be produced according to actual demand. The conventional length of the film volume is equivalent to 3000m or 6000 μm.

PET film is a kind of comprehensive performance packaging film. Its transparency is good, glossy; With good air tightness and fragrance protection; Medium moisture resistance, moisture permeability decreases at low temperature. PET film has excellent mechanical properties, its strength and toughness is the best of all thermoplastics, tensile strength and impact strength is much higher than the general film; And good strength, stable size, suitable for printing, paper bags and other secondary processing. PET film also has excellent heat and cold resistance and good chemical resistance and oil resistance. But it is not resistant to strong alkali; Easy to take static electricity, there is no appropriate anti-static method, so attention should be paid to the packaging of powder items.
