Celons – pronounced ‘seal-on’

Tuesday, October 14th, 2014

Celons pronounced ‘seal-on’ as they are called in the US, or a viskring as we call it in the UK, or simply a tamper band or whatever you preferred term there are probably a few things you don’t know about this product. A celon is a cellulose band, and it possesses unique properties that have never been duplicated by any other product. The primary use is as a superior neck seal for glass, plastic and tin.

The celon is applied wet in its expanded form. When allowed to air dry, it shrinks to a skin tight film. When removed it leaves a clear surface, no glue or other residue remains.
The basic ingredients of Celons is purified wood pulp in the form of large, white sheets. This pulp when subjected to special treatment is converted into an amber liquid known as Viscose. The viscose is extruded through nozzles into a solution where the beginning of the regeneration takes place. This regeneration as well as purification continues foe several hundred feet at the end of which Celons / Viskrings come off as continuous tubing.

They are available in a wide range of colours. Printing is done with a special impregnation process in their hydrated form. High Speed cutters trim to size and stack the celons allowing the operators to stack them in neat rows inside special containers either tins or pails. They are then covered in a plasticizer.


Printed 100% Biodegradable Tamper Evident Seals

Thursday, July 17th, 2014

seals for pharmViscose supplies Printed biodegradable secondary seals, that shrink in the natural environment. Printed designs on Viskrings / Celons normally take the form of the company’s name, brand name, logo, trade mark, house crest or any design which would enhance the bottle label or container. These Printed biodegradable secondary seals are sold to many market sectors, pharmaceutical – used in labs, Food, drink and cosmetic and perfect to stop the ever increasing problem of counterfeiting.

Before you proceed with a new printed design, Viscose will supply artwork as the design would appear on the finished viskring / celon. Ideally good quality artwork should be provided to Viscose to work from. Tubing up to 144mm FW can be printed but the maximum size of design for printing is 95mm on one or two sides.

In some instances, designs can be printed to the edge of the viskring / celon,  however it is advisable to allow a 4mm margin at the sides, top and bottom of the viskring / celon as shown below. Our technical department will advise if the proposed designs required without a margin are acceptable.


Plant-Based Cellulose Super Material is as Stiff as Steel

Wednesday, July 2nd, 2014

Recent scientific findings into investigations in Cellulose, have unveiled the remarkable structural performance of plants could completely change what we think of as ‘green architecture’. Researchers at Purdue University who conducted an experiment on cellulose nano-crystals concluded that the material, which is the structural basis of plant life, has the stiffness of steel.

This bio-Cellulose, which we use to make our viskrings / celons is found in plants, vegetables, algae and some marine organisms and bacteria. According to a recent experiment conducted at Purdue University University in Indiana, this material could be the ultimate renewable resource, particularly since it is so abundant and produced as waste in the paper and food industry. Cellulose nano-cystals are a potential alternative to carbon nano-tubes, polymers and concrete.

When the researchers tested cellulose nano-crystals during the Purdue experiment, they found that this seemingly fragile material is only 500 nano-metres long, but exhibits the remarkable stiffness of 206 gigapascals – the same as steel.

Because of the tiny sample sizes, testing this material was impossible in the past. This time the scientists used quantum mechanics to unlock the super material’s potential, a scientific breakthrough that could open the door to a future in which all architecture could mimic the structural performance and behaviour of plants.
