Bio Jar Seals | Tamper-Proof Bands

Uniquely distinguished tamper-proof seals made from 100% biodegradable cellulose. Perfect for sealing up jars and bottles but also works with plastic, metal, even irregular shaped items.

These environmentally friendly Viskrings are a popular method for sealing jars. They work by creating a tamper-evident seal around the jar lid, helping to preserve shelf-life of come products.

How do they work?

Remove a band and wrap over the lid on your jar. Once left it will begin to dry and shrink, after 60 minutes the band will have shrunk (up to 30% of its original size), sealing your lid and container in a safe and secure manner.

So what are they made from?

Basically they are eco-friendly cylindrical bands made from cellulose (derived from wood pulp). As they are made from this environmentally friendly renewable resource, the seals are 100% biodegradable and will break down faster than paper once they have served their purpose.

Application and Storage

We supply Viskrings packaged in tins containing approximately 1355 bands. Viskrings must be kept out of minus temperatures and the preservative solution must not be diluted or the solution could be at risk from bio-degradation.
