What determines the softness and hardness of plastic bags? Materials or processing technology?

by admin

basically, the price of soft is a little higher. The brittle and hard ones are generally made of PP or pet, and the grade is lower. Soft is generally made of multi-layer coextrusion film, with good barrier and feel. This kind of soft film costs about 27000 yuan /ton, while PP film is generally only 17000 yuan /ton, a difference of 10000 yuan /ton.

the quality of plastic packaging is determined by both materials and technology. No matter how good the materials are, it is impossible without good technology. However, the hardness of plastics is not the decisive factor to determine the quality of plastics. It mainly depends on what kind of products are used and what kind of products are needed.

determined by material! As for the price, soft is not the so-called cooked plastic. Hehe, I thought so when I was a child! The so-called cooked plastics let me see, that is, professional thermoplastics

generally speaking, those that are softer, have greater toughness and strength, and have the best quality and durability. Of course, the price should also be higher
