How to prevent PCR polyolefin shrink film from degradation?

To prevent the degradation of PCR polyolefin shrink film, the following measures can be taken:

Avoid exposure to sunlight:

PCR polyolefin shrink film may be sensitive to ultraviolet light, so it should be protected from direct sunlight during storage and transportation. It is possible to store and transport the film in a shaded environment, or to use packaging materials with ultraviolet shielding function.

Control temperature:

High temperature environments may accelerate the degradation process of PCR, so it is necessary to control the temperature during storage and use. Avoid exposing PCR polyolefin shrink film to high temperature environments, especially during processing and use, to prevent the film from deforming and degrading due to excessive temperature.

Control humidity:

Humidity also affects the stability of PCR polyolefin shrink film. Too high or too low humidity may accelerate the degradation process of the film. Therefore, it is necessary to control the humidity during storage and use, and avoid exposure to humid or dry environments.

Choose suitable packaging materials and methods:

Choosing suitable packaging materials and methods can effectively protect PCR polyolefin shrink film from the influence of external environment. For example, it is possible to choose packaging materials with good sealing and ultraviolet resistance, and to ensure that the packaging is intact to prevent the entry of air and moisture.

Avoid mechanical damage:

During handling and use, it is necessary to operate carefully to avoid mechanical damage to PCR polyolefin shrink film, such as scratches, cuts or tears. These mechanical damages may accelerate the degradation process of the film.

By controlling environmental conditions, selecting suitable packaging materials and methods, and avoiding mechanical damage, it is possible to effectively prevent the degradation of PCR polyolefin shrink film and maintain its stable performance and quality.
