International Plastics carries a wide range of Shrink Wrapping film and Polyolefin Shrink Film to meet every need. Shrink Packaging Film and Polyolefin Shrink Wrap Film.
We have two different types of shrink film depending on your application. Polyolefin is usually soft; if you squeeze a piece of it in your hand, it's soft like Saran wrap. PVC, on the other hand, is crinkley like cellophane. Our polyolefin films can be used for any application including foods. The PVC film we have is rated for indirect food contact. The higher the gauge, the thicker (and most of the time, stronger) the film. So use 100 gauge for heavy duty wrapping applications. 60 gauge or thinner can be used for less demanding applications such as tamper proofing soft ware boxes.
PVC Shrink Wrap & Shrink Film provides for higher clarity. Low heat is required to shrink PVC film (200-275°F) vs. Polyolefin shrink film (300-375°F). PVC Shrink Wrap can easily use heat gun or a small, less expensive tunnel, to shrink. The PVC film is available in smaller shrink force. PVC Shrink Film is strong and flexible heat shrink film.
PVC film is still very popular for use with CD and DVD packaging. You will also find PVC film being used to package boxes, software and other non-edible products. PVC film is more brittle than Polyolefin film and is not good for use with bundling multiple products. PVC film is also not safe for use with food products. PVC film emits an odor that some may find irritating if being used indoors. It is always recommended to use PVC film in a well-ventilated room.
Polyolefin film is very popular for use with food products, gift baskets, bundling multiple products and more. Poly film is more pliable than PVC film and does not tear easily. Polyolefin emits little odor and is fine for use indoors. As mentioned before, polyolefin is perfectly safe to use with food. Unlike PVC film, polyolefin film doesn't become brittle and yellow with age or break down during the heat-sealing phase of packaging. PVC production lines create odor and smoke as the film deposits on the sealing equipment and carbon builds up on the sealing tools over time. This doesn't happen with polyolefin film so there is less maintenance and a cleaner, higher quality overall appearance.
