Hot Perforated Shrink Film

In order to improve the quality of our film, Graso has introduced the films with micro-perforation.

Hot perforated film enables easy opening master packages of e.g. jars, cans or bottles, etc. The use of such packaging system improves also ventilation and reduces the humidity inside the package.

Hot perforation ensures fixed hole diameter after shrinking the package in the heating tunnel. Perforated film is also used for packaging of bread, plants in pots, and vegetables.

We may produced hot perforated OPP, CAST PP, LDPE and HDPE films

In the entire width of the strip or slit into narrower coils, subject to the Customer's needs. It is also possible to adjust the hole diameter.
