Release Liners: Their Role and Importance Explained

Simply put, release liners are coated papers or films that protect the adhesive layer that often is part of a pressure-sensitive tape or reclosable fastener. They protect the adhesive until it is ready to be exposed and affixed to the surface/substrate. Release liners are typically required whenever there is a pressure-sensitive adhesive backing, whether a reclosable fastener, a single or double-coated tape, foam, film, or foil.

A highly important component from a delivery and application perspective, release liners are often perceived as a low-value component of the overall fastener, mainly because they are usually discarded following application. As a result, the key role they play is often under-appreciated. In most applications, it is possible to remove the original factory liner and replace it with one or 2 release liners better suited to its end use.

Typically, there are two formats of release liners: single-side coated (C1S) and double-side coated (C2S). C1S liners provide protection for an adhesive that is laminated to a film or paper substrate. These liners primarily serve as a delivery mechanism for adhesives undergoing automatic or manual applications. Double sided (C2S) liners, also referred to as differential release liners, are coated on both sides with release coatings designed to provide differing release values.

Release liners can come in many different materials, paper, poly-coated paper, polyester film, polyethylene, or polypropylene, and may be coated on one side to provide a non-stick surface. They are used in numerous applications in conjunction with various pressure-sensitive tapes and converted solutions. The released coatings can be either silicone or non-silicone.

At Gleicher, we've found that by thinking through the final assembly process well in advance, we can produce a variety of attributes that ensure the liner is precisely matched to the adhesive, designed for the application, and configured for the assembly process.

When Gleicher is supplying a die cut solution that includes a release liner, it is critical to understand the following application aspects:

Will the adhesive be applied to the end part, or does it make more sense to apply the end part to the adhesive?
At which stage or at what point in the assembly process will the product adhesive be exposed and applied?
Are the parts being applied manually or automatically as part of a production process?

The answers to questions like these and many others help guide us in selecting from a wide range of converting considerations such as whether the release liner should be the same size as the geometry of the die cut part, or in what format to supply the finished material, such as kiss cut in rolls (with or without a perforation between parts), multiple strips on a single sheet/pad, or individual pieces.

When properly configured, a release liner solution can be engineered to come off at the right time and right stage of the application process, and pre-release or non-release problems can be avoided.

Comparing Silicone Release Chemistries | Release Liners

For release liners, there are many options for silicone release coatings. Silicone chemistry can play a crucial role in various industries, from manufacturing to tapes to medical and healthcare devices, where precise release characteristics are essential. These coatings are applied to paper or film substrates to create release liners, which are used to protect adhesive and other sticky materials until they are ready for application. Understanding the nuances of silicone coating options is critical for optimizing performance in different applications.

Release liners are integral components in the manufacturing and application of adhesive products. They provide a non-stick surface that allows for the easy removal of adhesives without leaving residue or damaging the adhesive bond. Silicone coatings are widely used for their superior release properties and versatility across diverse industries.

Silicone Release Coating Options for Your Application

Silicone release coatings can be broadly categorized into solvent-based, solventless (thermal-cure), and emulsion-based coatings. Each type offers distinct advantages depending on the specific requirements of the application.

1. Solvent-Based Silicone Coatings: These coatings are applied using solvents that evaporate during the drying process, leaving a thin silicone layer on the substrate. Solvent-based coatings are known for their fast curing times and excellent release properties. They are often used in applications where rapid production speeds are required.

1. Solventless (Thermal-Cure) Silicone Coatings: Also known as thermal-cure coatings, these formulations do not require solvents and instead cure through a chemical reaction induced by heat. They offer improved environmental friendliness due to lower VOC emissions and are suitable for applications requiring high-temperature resistance.

1. Emulsion-Based Silicone Coatings: These coatings consist of silicone dispersed in water, making them environmentally friendly with low VOC emissions. Emulsion-based coatings offer good adhesion to various substrates and are often used in applications where odor and flammability are concerns.

Silicone Coatings Can Affect Release Liner Performance

The first step in working with the team at Fox River Associates will involve a series of questions about your application, manufacturing environment, processing conditions and storage environment. Each of these elements can be critical to determining the most appropriate release liner components: substrate (paper and film), release coating, and curing method. When the Fox River Associates team recommends a release liner for your application, they’ve considered several factors to ensure optimal performance.

Release Force: Release force refers to the amount of force required to separate the liner from the adhesive or sticky chemical. Release force is influenced by factors such as coating thickness, surface smoothness, and the type of silicone chemistry used.

Adhesion: The adhesion between the silicone coating and the release liner substrate is crucial for ensuring the release liner remains intact during processing and application. Proper adhesion prevents delamination and ensures consistent release performance.

Chemical Resistance: Silicone coatings on release liners provide excellent resistance to chemicals and oils, making them suitable for applications exposed to harsh environments or aggressive substances.

Temperature Stability: Depending on the application, silicone coatings must maintain their release properties at both low and elevated temperatures. Thermal-cure formulations are sometimes preferred for applications requiring superior heat resistance.

Substrate Compatibility: The compatibility of the silicone coating with the release liner substrate material (e.g., paper, film) affects the overall performance and durability of the release liner. Surface treatments and primer coatings may be necessary to enhance adhesion.

Environmental Impact: Increasingly, manufacturers are prioritizing coatings with low VOC emissions and minimal environmental impact. Emulsion-based coatings are favored for their eco-friendly characteristics.
