The containment performance of stretch film depends on several critical technical variables, including resin quality, gauge thickness, and pre-stretch ratio. High-performance films can stretch up to three hundred percent of their original length, which maximizes material utilization and holding force. Proper application tension is essential; too little tension causes load shifting, while excessive tension can crush fragile packaging. The cling properties of the film also dictate how well the layers bond together to prevent unravelling. Environmental conditions, the profile of the pallet load, and whether it is applied manually or via automated machinery further impact containment.
