What is PVC & Polyolefin Shrink Film?

What is PVC  & Polyolefin Shrink Film?

Shrink Wrap also known as Shrink Film is a material made up of polymer plastic film. When heat is applied to the Shrink Film it shrinks tightly over whatever it is covering. Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass on a conveyor through a heat or shrink tunnel.

There are a variety of uses for Shrink Film. Manufacturers and businesses alike turn to Shrink Fim to protect and display their goods. A shrink-wrapped item in a store will remain clean no matter how many people pick it up and examine it. Shrink-wrapping also offers a psychological benefit to the consumer, creating an ‘untouched by human hands’ appearance that makes your goods look ‘factory-fresh.’

Shrink Film : the two most commonly used types are :

PVC Shrink Film
PVC or Polyvinyl chloride was up until recent times before the release of Polyolefin, the most commonly used Shrink Film available. However it was never been allowed to be used within the Food Industry as it releases small quantities of hydrogen chloride into the air and carbon deposits onto the sealer. Proper ventilation is required when sealing PVC Shrink Film. PVC Shrink Film uses include: packaging boxes, CD and DVD packaging, software, small canisters, and other non-edible items.

Polyolefin Shrink Film 
Whilst Polyolefin is commonly more expensive than PVC Shrink Wrap, it has become the preferred choice for packaging products both edible and non-edible. Polyolefin Shrink Film is preferred for a variety of reasons including: fewer odors when sealed, provides a stronger seal and can be stored in a wide range of temperatures and does not harden and soften in different environments.

Applications include: toys, sporting goods, printed wrap, food and drink packaging, stationary and cards just to name a few.
