POF shrink wrap is made from 100% recyclable materials, and is FDA approved. POF is available in 35, 45, 60, 75, and 100, 1 mil gauges. POF is puncture resistant, and has a strong seal strength, which allows it to be used for irregularly shaped items. ![]() Polyolefin or POF shrink wrap is a premium shrink wrap, as it's extremely durable and versatile. PVC has some negative qualities including, it is not good for bundling, leaves carbon deposits, and has a low shrink force. PVC has been banned in many countries, due to the harmful products created by its decomposition. However, it should be used in a well-ventilated area, as it can give off a strong, harmful odor. PVC is durable, and can be used for many different purposes. PVC is the most used shrink wrap, due to its light weight, and inexpensive capabilities.

Other shrink films include PVC, Polyethylene, Polypropylene, and several other compositions.Ĭoextrusions and laminations are available for specific mechanical and barrier properties for shrink wrapping food. The two primary films can be either crosslinked, or non crosslinked. It is available in a variety of thicknesses, clarities, strengths and shrink ratios. The most commonly used shrink wrap is polyolefin. ![]() Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.
