Viskrings- Self Shrinking Cellulose Closure

In our day to day life we come across with new Packaging innovations such as reusable packaging, biodegradable packaging and packaging using minimum material. Around the World many researchers, scientists, developers, designers are working on it.

In this phase of innovation, a U.K. based company “Viscose Closure Limited (VCL)” developed a biodegradable tamper evident self shrinking cellulose sleeves that shrink itself at room temperature. Yes it’s true; these sleeves are biodegradable as they are made of regenerated cellulose derived from the wood pulp of fast-growing soft wood trees. These sleeves do not require any hot air, hot bath or high temperature to shrink. These sleeves are also called Viskrings.

These rings are sufficient to provide a tamper-evident and counterfeit-proof secondary seal over any primary closure. Viskrings are non-toxic and preserved in mild preservative such as Polyethylene Glycol solution. These sleeves are supplied and applied in wet condition by hand or machine and allow drying and shrinking for 20 to 40 minutes. Viskrings shrinks 30% in transverse direction and 10% in vertical direction. Viskrings can be white, transparent, colored and printed. It can also be used as label, tamper-evident seal or as combined.

Benefits of using Viskrings- tamper-evident, anti- counterfeit, prevent leakage, simple and inexpensive, tough & durable, cost effective and environmentally sound. The companies in which it can be used are- Food, Herbs, oils, Pharmaceuticals, Cosmetic, Beverages and Gas Cylinder. We can say this product is suitable where heat is used at a very critical point to pack the product.

Viskrings have tensile strength of 45-60 Kg/cm2 and can be manufactured in 400 different colors. Viskring not only provide a biodegradable packaging but also provide colored, printed, tamper proof, heat proof and strengthened packaging.

Viskrings by Viscose Closure Limited (VCL) are now also available in India. For more details please visit to
