Shrink Film is a widely used method of packaging and/or unitizing products. It has a great appeal in the retail market because of its relative strength, clarity, ease of use and it is tamper evident. Individual applications require specific film characteristics.

Shrink applications vary depending on your product, equipment, and speed requirements. It is important to know and trust your source to match your needs with the proper shrink film. To satisfy your needs through the whole cycle, we also sell and service shrink wrapping equipment. Feel free to contact us today to speak with an experienced representative.

It is very important to understand how the various types of film differ. Shrink Film is available in four types:
 
Polyethylene
Polyethylene has the least clarity. This film is generally associated with high speed applications where you are not concerned with "eye-appeal". It tends to be hazy or cloudy. It frequently comes in heavier gauge associated with heavier packages. It has very high tensile strength and high tear resistance. It is much less expensive per pound than the other three films.
  Examples: cases of soup or soda, bundles of magazines
 
Polypropylene
This film has the highest clarity. It is generally associated with super high speed applications of light weight packages or individually wrapped products. Typically, it is low gauged with very little tear resistance. Typical applications are for "form, fill, and seal" equipment.
  Examples: audiocassettes or cigarettes
 
Polyolefin
This film is the most versatile film available and has good clarity. It is generally associated with medium or higher speed applications where "eye-appeal" and form are important. It has good tear resistance and is considered very "forgiving" to error.
  Examples: varies from print and paper trade to retail single and multi-packs, toys, and food
 
PVC (Poly Vinyl Chloride)
This product has extremely high clarity and is considered a versatile film. It is generally associated with medium to very low speed applications where "eye-appeal" is important and low end equipment is being used. It has very good tear resistance but can be brittle (especially in cold environments).
  Examples: the print trade or video cassette market where volume is small
