Shrink wrap is something that, until you need to know about it, you wouldn’t even give a second thought. Many of us deal with shrink wrap almost every day and companies use it in a myriad of different ways. Not all shrink wrap is the same, however, and there are some key differences between the materials that may make you decide to use one kind over the other. We’ll help you with understanding the different materials in shrink wrap so you can make a more informed decision.
Polyvinyl Chloride (PVC) Shrink Wrap
Perhaps the most common type of shrink wrap, and the one that many people are familiar with, is PVC shrink wrap. It’s rather inexpensive to produce, has many different applications, and is overall very light weight. PVC shrink wrap can be both rigid and flexible. Rigid PVC you probably know from things such as blister packaging or clamshell packaging. Flexible PVC shrink wrap makes up a lot of bags and commercial shrink wrap. PVC’s big downside is that it’s hazardous to create and destroy. Facilities that create it must be well-ventilated to protect workers from the dangerous fumes caused from it heating up.
Polyolefin (POF) Shrink Wrap
POF shrink wrap has become more of the gold standard when we try to understand the different shrink wrap materials. POF is known for being very tough and durable, allowing it to have a long shelf life and provide superior protection to products wrapped in it. POF is also approved for use on food products by the FDA. This material can be useful when packaging oddly shaped products, as it’s still very strong even when molded into irregular shapes.
Polyethylene (PE) Shrink Wrap
PE shrink wrap is an offshoot of POF. During polymerization, manufacturers will add in ethylene to increase the strength of the final product. PE shrink wrap’s biggest strength is its ability to handle much heavier loads than the alternatives. A bonus to using PE shrink wrap is that you can print on it, allowing for brands and designs to show up on shrink-wrapped packaging. This printing procedure doesn’t affect the strength of the wrap at all, which creates a lot of unique opportunities for this material.
