Shrink Films

Oriented plastic films made of thermoplastic and/or elastomer type polymers or copolymers. Top

Shrinkage characteristics

Shrinkage characteristics are built into the film during its manufacture by stretching it under controlled temperatures to produce orientation. These films can shrink back close to their unstretched dimension at temperatures higher than the temperature of their orientation. The shape of the packaging at the development stage of the Sleever, certain characteristics such as the shrinking and softening point of the film, are critical.
