Why do you punch holes in the shrink film?

Customers who have not used shrink film do not know why they should make a small hole in the shrink film. Many people will ask what is the use? Below I will briefly introduce what is the use of punching holes in the shrink film.

In fact, our so-called punching is not as big as you think, just like a pinhole is pinched. The punching can't be too big. If it is too big, it will make the moisture and dust in the air enter the packaging. The inside of the product will not only pollute, but also affect the shrinkage effect of the POF shrink film, and leaving such a small hole can prevent the internal air from being unflattened due to air exhaustion after packaging.

Therefore, when purchasing POF shrink film, you can ask the merchant to make one or two small holes in the film.
