Product Selection
There are two components to a release liner: the substrate and the silicone coating. Both of these need to be carefully selected to ensure that the liner has the required properties. The choice will normally depend on the following:
▪ the type of adhesive to be used
▪ the conversion process requirements
▪ the performance requirements of the finished product
By careful selection of both substrate and coating technology we are able to offer products for a wide variety of applications. A number of our products can also be back printed or printed under the silicone coating to allow the use of customer logos or provide product differentiation.
Substrates
Cotek offers a range of substrates with a wide range of physical properties:
▪ Supercalendered kraft
▪ Sized/ primed kraft
▪ Clay coated kraft
▪ PE coated kraft
▪ High density polyethylene film
▪ Polyester film
▪ Vegetable parchment
▪ Greaseproof paper
Coatings
Cotek uses three main types of coating technology:
▪ Thermally cured solventless silicones
▪ Thermally cured aqueous emulsion silicones
▪ Ultra-violet radiation cured silicones
The release of the thermally cured systems can be controlled to different levels.
