What is the Characteristics of BOPP film?

Biaxially stretched polypropylene film [1]

It has the advantages of lightweight, non-toxic, odorless, moisture-proof, high mechanical strength, good dimensional stability, good printing performance, and good transparency. It has advantages such as high transparency, good luster, good barrier, high impact strength, and low temperature resistance. Its disadvantage is that it is prone to film shrinkage during heat sealing (except for the use of its heat shrinkage performance by heat shrinkable smoke films). Its comprehensive performance is superior to moisture-proof

Cellophane, polyethylene (PE) film, PET film. BOPP film also has excellent printing performance. The representative physical property data is: turbidity<1.5%; Glossiness>85%; Tensile strength (longitudinal/transverse)>120/200MPa; Elongation at break (longitudinal/transverse)<180%/65%; The elastic modulus is 1700-2500Mpa; The embrittlement temperature is -50 ℃.

Disadvantages: The elongation is lower than PP, the heat sealing performance is poor, and it is not easy to seal when used independently. When used, it is generally compounded with films with good heat sealing properties such as PE.

Advantages: High tensile strength, good barrier performance, and high transparency.

Due to the directional effect of molecules, the crystallinity increases, resulting in improved tensile strength, impact strength, rigidity, toughness, moisture resistance, transparency, and improved cold resistance of the film

Has good air resistance and moisture resistance

High transparency, good gloss, and good printability

It is non-toxic, odorless, and odorless, and can be directly used in situations where it comes into contact with food and drugs.
