What is Shrink Wrap?

Shrink wrap is a polymer plastic film that is used to cover products. Shrink wrap is applied to tightly fit a product using a heat source that shrinks the wrap to the particular dimensions of the product it&#;s covering. The source of heat is either generated from a hand held heat gun or through a shrink tunnel. Some of the more common uses of shrink wrap include:
  • Securing boxes
  • Unitizing canned goods and beverages
  • Providing additional product protection
  • Tamper evident sealing
  • Securing large pallet loads
  • Combination packaging
  • Promotional packaging and sampling

Types of Shrink Wrap Machines

For applications that are larger in scale, a handheld heat gun won&#;t cut it for shrink wrapping products. Instead, automated shrink wrap machines are required to shrink wrap products in a quick and efficient manner. Some of the various types include:

Heat Sealers

Regardless of size or scale, most shrink wrap operations use a heat sealer to seal the open ends of the shrink wrap material. Shrink wrap sealers can come in a variety of sizes and forms depending on production needs. The two most common heat sealers for smaller operations are I-Bar sealers and L-Bar sealers.
I-Bar Sealer
An I-Bar Sealer is a shrink wrapper with a single sealing bar that seals the wrap to enclose the product. I-Bar machines are usually found in operations that feature a lower output, as they don&#;t excel at high speeds.
L-Bar Sealer
L-Bar Sealers are shrink wrap machines that are more efficient than I-Bar Sealers, as they function at a higher speed. The L-Bar sealer has two sealing bars in the shape of a backwards L, which is where its name derives from.

Shrink Tunnels

Shrink tunnels are designed for shrink wrap applications that have large operations and are industrial in scale. Shrink tunnels are commonly paired with L-bar sealers to boost efficiency. The heating system of a shrink tunnel far outperforms the heating power of a heat gun, which allows it to handle industrial-level loads. Shrink tunnels are manufactured to operate at semi automatic and fully-automatic speeds.

Shelf-Ready Products for Purchase

Another reason why every packaging company should invest in a shrink wrapper machine is that they pack products so well that they are shelf ready for market consumption. Dated technology or hand-wrapping products are usually not shelf ready. In the case of grocery stores, they will often take the product out of its tray or packaging before placing it on the shelf. Packed correctly using the right shrink wrapper technology and packaging process, your products can be packed to be ready for market when they arrive at their destination. This saves valuable labor costs, which makes your customers happy.
