The term shrink wrap is a generic term often used in commercial packaging, retail packaging, food packaging, and industrial packaging. Compared to other forms of packaging, shrink wrapping is often much more affordable and often times more efficient. Another reason is the attractive appeal to the consumer on the retail shelf. To maximise space, maximising on cost and shelf appeal makes it the new way to package just about anything.
All of the types of shrink wrap listed below require heat to be applied for the material to begin shrinking.
The main difference between shrink tubing and shrink sleeves is shrink tubing is often on a continuous roll. Shrink sleeves are pre-cut to fit the product being packaged. Shrink tubing is often made from PVC of Polyethylene. Tubing made from PVC is often used for retail packaging longer objects while polyethylene tubing is often used for packaging cases of liquids and canned products.
One of the most common types of shrink wrap for retail packaging. Centrefold shrink wrap is folded in half length-ways and placed on a roll. This allows users to slide the product being wrapped between the films, seal the open ends, and then apply heat. Centrefold shrink wrap is most commonly made from PVC and Polyolefin. Some suppliers do offer a Polyethylene centrefold shrink film.
Another very common type of shrink wrap for retail packaging. Shrink sleeves are often printed on and placed over bottles to brand products. Shrink sleeves often have a lower maximum shrink rate to keep from distorting printing. Preparing plates and design mock-ups can often be extensive as well as meeting required product minimums.
