Customers who used POF shrink film for the first time, when asked whether to punch holes in the film, felt quite at a loss, and did not know whether it should be punched or not. Now I will briefly talk about the situation of perforating the POF shrink film.

In fact, this so-called hole is not as big as we thought, that is, it is a small point like a needle pierced. If the hole is too large, not only will the dust and moisture in the air enter the inside of the packaged product, but it will also affect the shrinkage effect of the POF shrink film. And leaving such a small hole can prevent flatulence in the interior due to poor air exhaust after packaging.

Therefore, when users purchase POF shrink film in the future, they can ask the manufacturer to make one or two small holes in the film.
