PVC -Offers preferential orientation (shrinks in only one direction) and low shrink force
PVC Rolls are temperamental with drastic heat or cold temperatures, causing brittleness when too cold, and wrinkling when too warm
Polyolefin is more expensive, but more durable- not as effected by temperature changes
Many types of Polyolefin are FDA approved
Lower clarity and appearance, not a easy to shrink out completely
Good for lower end applications and unitization (24-pack of waters), replacement of master corrugated shippers, larger items
More expensive, but durable
Thicker- offering more stretchability
Shrinks as cools rather than heats, requiring additional cooling space at the end of the tunnel.
No matter what the application, knowing your options can save you a ton in the long run. That's a wrap (PACKAGING PUN, HA!).
