Purpose
Viskrings are shrink sleeves which provide a tamper-evident and attractive seal over twist off caps. They are easily applied by hand and shrink quickly without heating to form a skin-tight fit.
Materials Used
Viskrings are made from cellulose which is bio-degradable. Viskrings shrink when they are left to dry naturally in the atmosphere to provide a tamper-evident and counterfeit proof seal.

All Viskrings for twist off caps are 25 mm cut length. We hold stocks of white and transparent Viskrings in popular sizes and these are despatched within 48 hours. Other colours and less popular sizes of white and transparent Viskrings are manufactured to order and will usually take 3-5 weeks to despatch.
