Shrink wrap film is constructed of a heat-shrinkable plastic material, made from either polyolefin or PVC. The term "shrink wrap" is most commonly used in the commercial printing and packaging industries for retail, food packaging, industrial packaging and more. But it is often also used for smaller organizations like churches and schools who periodically make baskets or other crafts.
What are the different kinds of shrink wrap film? Polyolefin is the most popular shrink option on the market because of the eco-friendly properties and the fact that it is safe for use with food products. It also offers great clarity and leaves less residue on your shrink machine for easier clean-up. It does not contain chloride, therefore, it does not emit any odors or fumes when heated, like PVC shrink film does. PVC shrink wrap is less expensive and is best for use with oddly shaped products that need a tight shrink, which makes it a popular choice for retail bottles, such as lotions. PVC stands for polyvinyl chloride and works well with high-speed machines.
How to use shrink wrap film: shrink wrap film rolls require a sealer and heat gun to close and shrink the material. Films will well with tabletop i-bar machines or floor standing tunnel systems. Simply wrap your product with the film, seal all the edges around your film, and then use a heat gun (when not using a tunnel machine) to shrink the film to the desired tightness around your products. Keep in mind that they will not shrink indefinitely and do have a maximum shrinkage, so you want the film close to your product for this reason, as well as to reduce waste.
Shrink wrap film can also be custom printed for your business. Please call (866)537-2244 for more information and to learn about custom options.

|Polyolefin vs. PVC Shrink Wrap Film - Benefits|
|Polyolefin Benefits||PVC Benefits|
|Very tough multi-layered co-extruded film||Very strong and flexible|
|Puncture resistant||Shrinks at lower temperatures|
|Strong seal memory to rebound||Excellent clarity|
|Unmatched glossy clarity|
|"Green" product is recyclable|
|Emits no smoke, no odor & no residue build-up|

|Polyolefin vs. PVC Shrink Wrap Film - Drawbacks|
| Polyolefin Drawbacks
|Cost [Polyolefin is a more expensive option]||Sealing strength|
| Machine Compatibility [Does not work with all
shrink wrap machines. Check your machine
capabilities before using]
| Storage Issues due to Temperature Fluctuations
[The plasticizer in PVC film hardens in cold conditions
& softens in hot conditions, compromising the strength
of the seal]
| Proper ventilation is required when using
[PVC releases small quantities of hydrogen chloride
into the air, & carbon deposits on the sealer wires]
Note: Often shrink wrap is confused with stretch wrap, however, they are different products. Stretch film is often used to simply wrap pallets of boxes, while shrink wrap shrink around items with heat. We also offer stretch wrap film; please call (866)537-2244 to inquire.
