Heat Shrink Seals
Shrink bands are a cost-effective way to provide tamper-evident protection to packaged goods. Heat shrink bands are manually applied over and around the cap of a container. Heat is applied using a heat gun or heat tunnel until the band shrinks and closely fits around the container. Perforated shrink bands feature a dashed series of incisions that have been made in the shrink band for easy removal of the seal. Non-perforated options are also available.
Polyvinyl chloride (PVC or V) has fair chemical resistance and is characterized by its streaky yet naturally clear finish. It has a good oxygen barrier, which makes it suitable for salad oils and vinegar. PVC is not compatible with solvents. General PVC will distort at 170°F and is not suitable for hot filled applications.
