Silicone Coatings - Release Liners

Commercial siliconiser producing release liners

Since the end of 2009, SJA Film Technologies Ltd has the capability to produce UV cured solvent-free silicone release films. Silicone Coatings / Siliconised Liner Products are supplied into a variety of markets, from mailing bags to carbon fibre composites.

Products can be matched to existing requirements or bespoke products can be made to meet customer requirements using various release formulations and/or base films. We are a flexible silicone coatings manufacturer able to produce smaller order sizes right up to full container loads.

Release Liners

Release liners are available in different colours and on different film types such as Polyester, Polyethylene and Polypropylene.

Thicknesses used currently vary from 12 microns to 200+ microns.

Silicone Coatings - Available in both pad and spool formats.

 

SILCONE COATINGS - FILMIC LINER RANGE

High Density Polyethylene (HDPE) Silicone Coatings

with good stiffness and strength, HDPE is ideal as a low cost release liner for industrial applications - e.g. bitumen membranes, bag release tapes and insulation panels.

Low Density Polyethylene (LDPE) Silicone Coatings

good tear resistance & flexibility, it is suitable for industrial and graphics applications where coloured film is required or where high clarity is not a priority.

Polypropylene (PP) Silicone Coatings

comes in a variety of forms (non-orientated, orientated, blown) and therefore a range of properties, PP provides a better heat resistance than polyethylene and is used in industrial and label applications.

Polyester (PET) Silicone Coatings

like bi-axially orientated polypropylene (BOPP), PET offers good clarity, tight gauge control, a gloss surface and good stiffness and strength with low stretch. However, PET offers superior heat resistance. PET is popular as a release liner for high value labels, graphics or medical products.

All products have excellent release from aggressive adhesives and release values can be modified to suit particular adhesives. They are unaffected by solvents of the ester, ketone and alcohol groups in addition to most general purpose solvents.

Applications

There are many different applications for release liner materials, such as:

  • Composites e.g. Aerospace industry, high performance cars and boats, turbine blades, golf clubs
  • Building and construction materials, e.g. underlay for roofing, window films, flooring materials
  • Pressure-sensitive labels and tapes
  • Hygienic application e.g. for Feminine Hygiene pads
  • Medical applications e.g. wound care
  • Release Liners

Why use siliconised films rather than papers?

  • Uniform thickness
  • High internal delamination resistance
  • Transparency
  • Excellent dimensional stability
  • High tensile and tear resistance
  • Smooth, maximum hold out surface
  • Customised flexibility or stiffness
  • Low compressibility
