Types of polyethylene plastic film and their respective characteristics
Apr 03, 2019
Polyethylene plastic film is generally divided into three materials, the first is low density high pressure polyethylene; the second is high density low pressure polyethylene; the third is linear polyethylene, which has different characteristics. In terms of appearance, the high-pressure polyethylene plastic film has high gloss and high transparency; the low-pressure polyethylene plastic film has low gloss, fog, and the white-white frosted linear polyethylene plastic film has transparency, high gloss polyethylene and low pressure. Between polyethylene plastic film.
In terms of hand feeling, the high-pressure polyethylene plastic film is soft; the low-polyethylene plastic film is relatively stiff; the linear polyethylene plastic film has no high-pressure polyethylene plastic film which is smooth and soft, and is not as stiff as the low-pressure polyethylene film. Stretching these kinds of polyethylene plastic film, it can be found that high-pressure polyethylene plastic film has good impact resistance and large elongation; low-pressure polyethylene plastic film has high tensile strength and small elongation; linear polyethylene plastic film tensile strength It is higher than high pressure polyethylene and low pressure polyethylene and has moderate elongation.
Or some enamel on the polyethylene plastic film, it is found that the high-pressure polyethylene plastic film is smooth and low in sound, and easy to open after being made into a bag; the low-pressure polyethylene plastic film has a large sound, the bag is easy to open, and the film is ubiquitous. White, creased; linear polyethylene plastic film with small sound, the bag is not easy to open.
