Types of Material


- This material has extremely high clarity and is also 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. PVC film has very good tear resistance but can be brittle (especially in cold environments).
- Examples of usage - Shrink bands, the print trade, the video cassette market.

- This type of material is generally associated with high speed applications where "eye- appeal" is not an important factor.
- Polyethylene has the LEAST clarity of any of the different types of shrink film. Clarity with this type of film tends to be "hazy" or "cloudy".
Although it may lack clarity, Polyethylene has a very high tensile strength or resistance to tearing.
- Polyethylene is much less expensive per pound than any other types of film, and it is normally available in
the heavier gauges, and is therefore, quite often used in wrapping heavier packages.
- Typical examples of Polyethylene shrink wrap usage would be in wrapping cases of soups, sodas, and bundles of magazines. POLYPROPYLENE
- This film has the HIGHEST clarity of all films. It is generally associated with SUPER HIGH speed applications of light weight packages or individually
wrapped products. It is normally a low gauge film and, as such, it has

- Typical applications are for "form, fill and seal" equipment. Typical examples of its usage would be with audiocassettes or cigarettes.
POLYOLEFIN- Polyolefin is the most versatile film available, and it has good clarity.
- It is generally associated with medium or higher speed applications where "eye- appeal"
and form are important. Polyolefin has good tear resistance and is considered very "forgiving" to error.
- Examples of usage vary from the print and paper trade to retail single and multi- packs, toys, and food.
