Advantages of PVC shrink film 

·         Higher clarity

·         Low heat required to shrink (200-275°F) vs. Polyolefin (300-375°F)

·         Can easily use heat gun or a small, less expensive tunnel, to shrink

·         Available in smaller shrink force

·         Strong and flexible film

·         It’s “idiot proof”, very easy for any operator to use

Advantages of Polyolefin shrink film

·         Slightly lower cost per foot than PVC

·         Food grade film

·         Does not require cool storage as does PVC

·         No smell, and no smoke when sealing

·         Not as corrosive as PVC.  Creates less build up of material on machine sealing wires.  No need to use Teflon curtaining over sealing wire like PVC needs.
