Biodegradable Viskrings made from cellulose are being used by many premium food producers to provide a high quality tamper evidence and counterfeit-proof seal which, at the same time, give a very environmentally friendly seal.

For example, this Israeli producer of additive-free pepper sauces felt that the cellulose Viskring was more sympathetic to his ideas for additive-free foods than a plastic seal.

Viskrings are ideal for smaller producers because no machinery whatsoever is involved. Viskrings are pre-cut bands delivered in a preservative solution and after being applied to the container they dry and shrink spontaneously without the need for a shrink tunnel.
