Stretch wrap Plastic is often purchased as tubing, sacks, or rolls of film. Before applying heat, the plastic sheet is wrapped around its contents, shrinking in size and flawlessly moulding to the shape of what is inside.

The plastic polymers that make up the shrink wrap material cause this process to take place. The product is made of stiff, structured polymers when it is wrapped in pre-heated shrink wrap. The polymers, on the other hand, lose their structure and become free to move when heat is supplied to the film using a heat gun or heat tunnel.

These polymers disintegrate, causing the film to compress and contract around their contents. The polymers re-set in their new configuration as the film cools.

Their tensile strength rises when these polymers rearrange and shorten from their initial straight, extended condition. As a result, shrink wrap is strong and long-lasting, guarding against tearing and piercing and safeguarding its contents.

Shrink wrap packaging is ideal for retail packaging projects where customers must be able to see the product since it retains transparency even after shrinking.

Specifications of shrink wrap

Shrink wrap is a well-liked packaging choice because of its numerous positive qualities. The following are some of the appealing qualities of shrink wrap:

Tensile capacity

Due to its toughness, shrink wrap is impervious to tearing or puncturing. This appealing feature safeguards contents when they are being transported, stored on shelves, and stored in warehouses—especially food items, whose package integrity must be maintained to maintain consumer confidence.

Flexibility –

Shrink wrap is offered in a variety of thicknesses and shapes, including rolls, bags, and tubing. Due to this, it is perfect for usage with all of your products, including pizza and boats.

Completely sealable

Shrink wrap offers hygienic protection for its contents by having no open or exposed sides once it has been sealed. This helps prolong the shelf life of items like food.

Resistance to smells

Similar to how heat-treated shrink wrap prevents odours from entering the packaging and contaminating its contents, it has a thick and impermeable finish.
