In the world of self-adhesive vinyl, the spotlight is most often placed on the range of colour, the finish, application performance - but behind every film is one of the most important components that is usually overlooked: the release liner. Arlon understands the release liner is not just a place to add additional branding or merely to line the back of film, they protect the adhesive layer and give stability to these flexible vinyls to assist in the cutting, weeding and application processes. In fact, many of the properties of self-adhesive media such as shelf-life, adhesive properties and film finish are affected by the composition of the release liner. That’s why Arlon backs its range of colour cut films with synthetic liners - power amazing quality of life features that enhance every stage of colour graphic production workflow.
Synthetic Vs. Paper
There are two main types of release liners used with self-adhesive media, paper and synthetic liners. Paper release liners are commonly used due to their lower cost to produce, thickness and rigidity, which can make them easy to handle especially when working with larger graphics applications. It is normally coated in silicone to improve its moisture resistance properties to reduce dimensional warping that can occur.
Synthetic liners, normally composed of polyester (PET) or high-density polyethylene (HDPE), offering greater durability, moisture resistance, and dimensional stability compared to paper liners. While usually more costly, the performance advantages of synthetic liners can give you an edge in production, application and finish.
Lay Flat Stability
Synthetic liners are dimensionally stable, resisting moisture absorption and prevent any curling or tunnelling, keeping the vinyl flat and aligned. This can save a great deal of time having to recut graphics due to vinyl shifting or edge lifting, giving you more confidence processing larger jobs with precision – especially on flatbed cutters. This results in less concern with storage, production, and application.
The lay-flat properties inherent to synthetic liners keep vinyl flat to make storage, cutting and application, stress-free.
Multi-Layer Graphics
The transparency of synthetic liners is a game-changer, making precise alignment of cut graphics quick and effortless. This is incredibly helpful for multi-layered graphics, in which synthetic liners can save a huge amount of time, while making a professional finish as easy as can be.
Cutting and Weeding
Cutting and weeding normally take up a great proportion of time in most workflows, meaning the reliability of a self-adhesive media to cut-and-weed critical. The uniform surface of synthetic liners provides many advantages including:
• More consistent release from the adhesive for faster weeding.
• No adhesive bleed as with paper liners where coating can be cut-through.
• The smoother surface reduces vinyl tearing when cutting smaller details and lettering.
• The moisture and static resistance properties liners prevent vinyl from clinging or lifting incorrectly during weeding process.
Synthetic liners ensure sharper cuts, cleaner lifts and easier handling every time.
Brilliant Finish on Gloss Colours
Synthetic liners not only benefit production and installation but also enhance the finish of the self-adhesive media itself. The smooth, uniform surface of synthetic liners reduces any texture transfer into the face film of the media, resulting in more consistent and glossier finishes. Self-adhesives films backed with a synthetic liner can offer higher gloss levels, sharper colour, and a premium look that stands out.
