The difference in the characteristics, properties and applications of the two types of plastic film
About the characteristics
PVC film is manufactured from Polyvinyl chloride resin, usually ivory white or light yellow. This type of plastic is not as flexible and tough as PE plastic, to increase the flexibility of the finished product, people often have to add additives, but after a long time of use, it may lose its flexibility and become brittle. than. PVC film is also water vapor resistant, but less so than PE film. However, PVC film has better durability and impact resistance, very good insulation, and adhesion is also higher than PE film.
PE film is produced from PE Polyethylene resin, with high transparency, good flexibility, very good water and vapor resistance. PE film has lower stickiness than PVC film.
About the applicability
With their own characteristics, each type has different applications:
PE film, with the characteristics of being flexible, tough when stretched and difficult to tear, is widely used to wrap goods and preserve food. PE plastic is also used to make bags, or to make plastic films to cover rain and sun.
PVC film, due to its very good insulation, is used to make partitions and curtains for cold rooms. PVC film is also often used as packaging to preserve medical equipment, or to make household items.
