What is the difference between PE protective film and PET film? Dec 23, 2017

How much do you know about the difference between a PE protective film and a PET film? Then HUALIBAO's relevant technicians will tell you.


PE film and PET film are different materials, PE is soft, PET is hard; When it shakes, PE does not sound, PET has a sound; PE tensile strength is inferior to PET; PE film temperature resistance is generally 60 degrees, while PET can be 120 degrees and above.


If it is a protective film, the coating adhesive may be different; manufacturing methods may also be different.


PE protective film

PE, full name Polyethylene, is the simplest structure of the macromolecular organic compounds, the world's most widely used polymer materials. PE film is made with base material of special polyethylene (PE) plastic film, which is divided into high density polyethylene protective film, medium density polyethylene and low density polyethylene according to the different density.


The biggest advantage of PE protective film is to protect products in production, processing, transportation, storage and use process from pollution, corrosion and scratches, keep the product with the original bright and clean surface, thus improve the quality of the products and market competitiveness.


The application of PE protective film is as follows:


PE protective film is mainly used in stainless steel plate, aluminum plate, aluminum profile, plastic profile and doors and Windows, aluminum-plastic plate, fluorine carbon plate, mirror plate, sandwich steel, fire prevention board, PMMA, PS, PE, PVC board, sunshine board (polycarbonate plate), panels, coated glass, high-grade furniture, electrical cabinet, computer case, automobile lamps and lanterns, floor, household appliances shell, instruments and meters, all kinds of fields need protect the surface can be used.


PE film is made of special polyethylene (PE) plastic film and acrylic resin adhesive, and mixed with several special auxiliaries. It is soft and has good adhesive properties, can be easy to paste, easy to peel off and removed without residues.


PET protective film

PET film is also known as high-temperature polyester film. It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, which can be widely used in magnetic recording, photographic materials, electronics, electrical insulation, industrial film, packaging decoration and other fields. With the development of special functional film, the new application of polyester film has also been developed. It can be made into a mobile liquid crystal protective film, LCD TV protection film, mobile phone keys and so on.


The above mentioned is about the difference between PE film and PET protective film.
