Heat-shrink tubing is ordinarily made of a polyolefin, which shrinks radially (but not longitudinally) when heated, to between one-half and one-sixth of its diameter. Heat-shrink tubing is manufactured in a multitude of varieties and chemical makeups with the exact composition of each type being dependent on the intended application. [1]
The mainly used amorphous thermoplastic polyamides combine a favourable viscosity spectrum with a wide application temperature range from 50 to 150 °C or 122 to 302 °F. The material is heated until liquid (typically at 180 to 240 °C or 356 to 464 °F) and then injected at very low pressure, typically 3.5 to 14 bars (51 to 203 psi) into a ...
Heat shrink tape is applied to a composite part prior to the heating, or curing cycle. When heated, the tape will shrink in the linear (machine direction). Heat shrink tape works best on parts that are cylindrical or semi-circular in cross section, as this allows the tape to exert even compaction forces on the part surface.

Heat tunnel for shrink wrapping bakery goods in-line heating of shrink bands on plastic bottles of water Machinery to apply and shrink an overwrap. A shrink tunnel or heat tunnel is a heated tunnel mounted over or around a conveyor system. Items (such as packaging) have shrink film loosely applied; with heat, the film shrinks to fit snugly ...
Induction heating is a non contact heating process which uses the principle of electromagnetism induction to produce heat in a work-piece. In this case thermal expansion is used in a mechanical application to fit parts over one another, e.g. a bushing can be fitted over a shaft by making its inner diameter slightly smaller than the diameter of the shaft, then heating it until it fits over the ...

Key COC enhancements can include thermoformability, shrink, deadfold, easy tear, enhanced stiffness, heat resistance and higher moisture barrier. Common applications include shrink films and labels, twist films, protective or bubble packaging, and forming films. Another noted application which often relies on a high percentage of COC in the end ...
