Bar-code Label Materials

Bar-code labels are commonly converted out of paper, polyester (PET) or polypropylene. And adhesive, whichever the spec, is almost always permanent and not meant to be removed. Permanent adhesive (high-tack or regular) is usually used, unless the products are stored in the freezer, where you would need a freezer grade label adhesive.

In short

Paper general purpose applications.

Polyester (PET) durable, long-term outdoor applications.

Polypropylene short-term, high moisture applications.
