Heat Shrink Plastic Wrap Packaging

Also known as a type of film, this solution is a commonly used packaging material made of polymer plastic. Used to give security, durability and a heightened level of professionalism to product packaging, both PVC and Polyolefin are the most commonly used types, and one of Omni Group’s leading products.

But what is the difference between options made from PVC versus Polyolefin? We’re glad you asked. Let’s take a look at each and see which product would best suit your needs.

Exploring PVC Heat Shrink Film

A stronger more durable option, PVC is used for wrapping larger product quantities as a more cost-effective solution to Polyolefin. Applied using a handheld heat gun or on a conveyor-passed tunnel, this type of solution tightens to fit the product.

PVC films cannot be used for products in the food and consumables industry due to the small quantities of hydrogen chloride released during the process, and carbon deposits emitted by the sealer. As a result, PVC can only be used for non-food products and must be used in an area with proper ventilation to reduce the risk of harm.

Further, it should be noted that this plastic shrink wrap may have a cloudy, less translucent appearance once it has been applied to the product.

Polyolefin Heat Shrink Plastic Film

This option has a much softer, more delicate texture and is the perfect, safe solution for covering or presenting food. Safe from carbon or hydrogen chloride deposits, food-based product companies can also apply this solution to consumable items via a heat gun or conveyor, and maintain the integrity of their food.

Slightly more expensive than PVC film solutions, Polyolefin is often the preferred choice due to fewer odours being released during the sealing process. This provides a stronger seal, and because the film can be stored in a wide range of temperatures without over-hardening or softening, due to different climates.
