Video: What silicone base papers do in practice
For many self-adhesive applications, silicone base papers are the release liner of choice. It is important to have cost-efficient, straightforward, smooth siliconisation processes, as well as proper, error-free handling of the self-adhesive end product. Discover how you can rely on over 50 years of product experience with Sappi’s silicone base papers.
What is silicone base paper?
Silicone base paper is used as a release liner for various self-adhesive applications. This includes CCK and glassine papers from Sappi. They are subsequently siliconised by our customers through further processing. Thanks to their non-stick silicone coating, the papers are able to protect products such as adhesive tapes and self-adhesive labels from accidental sticking and also ensure smooth usage. The siliconised papers are also used as process liners in prepreg production.
Street signs, advertising on shop windows, protective films, and car graphics and design. These are just a few of the ways in which self-adhesive films and paper are used. To ensure that the end result meets the desired standard, a high-quality, silicone-coated base paper is required.
All types of adhesive tape
Whether it’s for carpet tape or industrial adhesive tapes, our silicone base papers will do the job. Industrial adhesive tapes are increasingly being used in the production of various products, including in the automotive and electronic industries.
Self-adhesive labels also need a good release liner. These labels are used on wine bottles, transport packaging, and for weighing fruit and vegetables, for example.
Self-adhesive office material
When labelling file folders or putting address labels or even shipping labels on parcels or letters, it is important that they peel off from the substrate as smoothly as possible. Our silicone base papers are also constantly used for this.
For composite material
Pre-impregnated carbon fibres are essential in the automotive industry, aerospace, sports equipment production and in many other manufacturing fields. Silicone base papers are used to separate the individual carbon fibre mats so that they do not stick together during transportation, storage and production.
