What are Shrink Wrappers?

The world of shrink wrap is vast and there are a wide variety of industries that utilize shrink wrap on their products. Due to the varying demands of shrink wrapping, there are a range of different shrink wrap machines and technologies available.Get more news about Auto Shrink Wrap Machine,you can vist our website!
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
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.
