What is the difference between PE stretch film and PVC stretch film?
1. PE wrapping film, also known as stretch wrapping film, has the function of stretching and shrinking, and is made of environmentally friendly substrate. It has high tensile strength, tear strength and good self-adhesiveness, so it can wrap the object in one piece and prevent it from collapsing and falling during transportation. The film has excellent transparency. The wrapped object is beautiful and can make the object waterproof, dustproof and damage-proof. The film is used for packaging of goods pallets, such as electronics, building materials, chemicals, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries. The adhesive is divided into single-sided adhesive and double-sided adhesive. The product is divided into two series: manual winding film and machine wrapping film.
2, PVC stretch film is used as a packaging film winding, no tensile force. Mainly used in industrial applications such as wire packaging. It used to be a toxic material and has been adjusted to meet environmental requirements. The evaluation from the feel is: in general, the texture of the PE stretch film is soft, and the handcuff does not emit too much sound. However, the wrapping film of pvc material is slightly harder in texture, and it will make a crisp sound when it is lightly rubbed.
