Shrink Wrap

Two major classification of shrink wrap:

1. For "point-of-sale" where the wrap has to sell the product-usually by not being in the way visually-rather expensive, special, oriented films are used. These films are very clear. When they shrink, they do so with alacrity, exerting energy on the product and shrinking with few or no wrinkles or distortion. This is high technology packaging where the film can be pre-printed with appropriate distortion so that the printing comes out perfect after it shrink.
2. Industrial shrink packaging, on the other hand, is done with more ordinary films which are less costly and shrinks when heated. In attempting to regain the form it was in or on its way out of the extruder.
