Characteristics of PVC shrink film punching

The characteristics of PVC shrink film punching are mainly reflected in the following aspects:

Improve air permeability: Perforation can make the film surface breathable, reduce the accumulation and corruption of water inside the film, and thus maintain the freshness of food and other items.

Improve moisture-proof effect: Punching creates tiny pores on the film surface, increasing air circulation between the film and the packaged object, allowing water vapor and oxygen to form local circulation on the film surface, further improving the film's moisture-proof effect.

Flexibility and adjustability: Laser perforation can adjust parameters such as hole diameter, hole shape and hole depth according to different needs and requirements, which is very flexible.

In general, shrink film perforation can reflect the performance of the film, improve the quality and shelf life of the product, and adapt to different packaging needs.
