Pe bag is a plastic bag, the use of materials is polyethylene, this material is not only non-toxic and tasteless and feel very good, more importantly, can meet the standards of food hygiene packaging. PP bags are mainly made of this material made of polypropylene, the use of the production process are mainly color printing and offset printing. That Pe bag with PP bag in the end what is the difference between it?
First of all, between the two feel different: Pe bag is relatively soft, hand feels like the feeling of wax, Rally strong, even if the kneading is not how to fold, PP bags are more brittle, easier to break, the interface is often Hot melt, kneading words will be wrinkled.
Second, the characteristics of the two are not the same: pe bag without taste, no poison, with a good resistance to low temperature energy, and the chemical properties are relatively stable, encountered strong acid and alkali will not change, at normal temperatures In the general solvent will not melt, and the water absorption is relatively small, but also has a good electrical insulation, but anti-aging is not very good. PP bags have good mechanical properties, good toughness, impact resistance is also better, in strong acid and alkali and organic solvents will not change.
In addition, the use of the range between the two is not the same, pe bags with more plastic bags there are some plastic film, but the use of pp bags are more in some industries, for a variety of food and beverage, etc. Provide a good packaging.
