Shrinking with Process Heat

Professional Shrinking with Leister

Leister Process Heat components are used in various applications within the Food & Beverage industry.

Instead of having a label applied to them, individual bottles are often wrapped in a decorative shrink-on hose, which, in this case, is referred to as a "sleeve." This sleeve may only cover a portion of the bottle, or may extend across the entire height. Another typical application is the use of shrink film to create a pack of multiple bottles or cans. Shrink-on caps are placed over wine bottle closures (screw tops or corks) to protect them against dirt or for decorative purposes. When these preformed caps are exposed to hot air, a uniform, tight fit is achieved around the neck of the bottle and closure.

The following materials are commonly used for shrink films, depending on the application: polyolefins (PP and PE), PET, and PVC.
