Vented Plastic Bags & Vented Poly Bags
Vented bags are used for a number of applications. Most commonly the vents are used for releasing air out to make packaging easier such as in mattress bags where air not being able to escape would make the packaging of mattresses more difficult. It is also used for food applications such as in micro perfed bread bags which allows steam to escape helping preserve the cruncy crust of a baguette.
