         Application of automatic hole punch in food packaging.Supermarkets are full of beautiful things in eyes put a variety of food packaging bags, so why packaging bags must be perforated?General packaging plastic bags do not need to perforate, but in order to release the air in the bag after sealing, to avoid air occupation of space, before the hole vent.Blowhole is hit commonly in bag body.There are also round holes or butterfly holes in the top of the bag, which are used for hanging, called hanging holes.

        Perforation in order to prevent children from suffocation of the bag on the head, there is another important reason is that if the plastic bag is not perforated, there will be air inside. After a long period of sea transportation, there will be water vapor inside, which will cause the products inside to be damp, mouldy or rusted.So make sure you punch it.
