Description

PET film

Technical Field

The utility model relates to a PET membrane technical field specifically is a PET membrane.

Background

The PET film is a packaging film with relatively comprehensive performance. The transparency is good and the gloss is good; the air tightness and the fragrance retention are good; moderate moisture resistance and reduced moisture permeability at low temperatures. The PET film has excellent mechanical performance, the toughness is the best of all thermoplastics, and the tensile strength and the impact strength are much higher than those of the common films.

For example, in the utility model patent of publication No. CN207875057U, a PET membrane is disclosed, including flexible PET membrane basement, the one side that flexible PET membrane basement and external world meet sets up the protective layer, the surface along the protective layer is equipped with the protruding rubber strip of a plurality of looks adaptations, the external one side from interior to exterior of keeping away from in flexible PET membrane basement is pasted in proper order and is covered the sclerosis layer, first conducting layer, second conducting layer and photosensitive look change layer, the photosensitive look changes the layer and keeps away from the one side of second conducting layer and is equipped with the protruding rubber strip of a plurality of looks adaptations, however this PET membrane lacks corrosion-resistant protection and leads to it to receive that chemical corrodes the back life lower.
