We usually need to hold boxes and products together on a pallet for movement and transportation。We will start with stretch film. It’s the most common product to hold objects together and protect them during transport and storage. 
Also have many clients reflect on the water droplet formed on the stretch film.it will immerse into the box or carton,form the mark or stain on the box or carton,even worse, reduce the strength of box or carton.
So we have the kind of stretch film with holes,the air can flow freely,but the strength of stretch film also can be remained.
