Viskring shrink seals are the preferred method for providing tamper-evidence to the range of confectionery products made by Cheddar Sweet Kitchen.

Transparent Viskrings were chosen to have minimal visual impact on the pack design. The pre-cut seals are applied by hand on to the neck of the jars and shrink down to a tight fit, holding the push-in cap in position. The seal must be broken in order to remove the cap.

Viskrings are made from cellulose and are stored in a preservative solution. On application they dry naturally at ambient temperatures and shrink as they do so. No machinery or shrink tunnel is required. This is an ideal sleeving solution for small to medium sized operations, especially those producing heat-sensitive products.
