About Color stretch film

Color stretch film, also known as color wrap film, color heat shrink film, color wrap film good adhesion so that the outside of the packaging film layer and layer stick together to make the goods firm, there are two main methods of obtaining adhesion: one is to add PIB or its masterbatch in the polymer; the other is mixed with VLDPE. PIB masterbatch is used. Wrapping film has good buffer strength, puncture resistance and tear resistance, thin thickness and good performance to price ratio. Wrap film has high tensile strength, tear strength, transparency and good shrinkage.

Wrapping film, also called stretch fllm, is produced by using imported LLDPE resin and special additives of adhesion enhancer. The earliest PVC winding film in China was produced with PVC as the base material and DOA as the plasticizer and self-adhesive. Due to environmental problems, high cost (relative to PE ratio, less unit packaging area), poor stretching, etc., when the domestic production of PE stretch film in 1994 ~ 1995 began to be phased out. PE stretch film first EVA as a self-adhesive material, but its high cost and taste, and then developed with PIB, VLDPE for self-adhesive materials, the base material is now LLDPE for the party, including C4, C6, C8 and metallocene C6, C8 and metallocene PE (MPE).
