Shrink Film

D-940 SOFT SHRINK FILM

Catalogue:  Brochure_D-940

Cryovac’s “friendliest” film, D-940, is all about making your life easier. With its low shrink tension and forgiving nature, D-940 is the perfect film for those products difficult for packing, such as soft and light-weight products.

 

Features

  • Multilayer co-extruded cross-linked polyolefin film
  • Low shrink force - soft shrink applications
  • Shrinks packages distortion-free at extremely low temperatures
  • Eliminates the need for corrugated or chipboard inserts for small unsupported packages
  • Will not deteriorate equipment with corrosive discharge fumes like many PVC films
  • Seals are strong, not brittle
  • Resistant to shrinking back on the roll and blocking when exposed to heat, crystallizing and becoming brittle when cold - characteristics of PVC films.
  • The length of each roll is longer than PVC films to give the benefit of increase the production efficiencies because of less frequent changeovers

Application
