Die cutting and kiss cutting are precision processes used across many industries, from medical devices and electronics to tapes, graphics, and automotive applications. At the core of these processes lies a critical component that ensures quality and efficiency: the release liner. Whether engineered of paper or film, release liners provide the foundation that allows converters to create accurate parts, manage adhesive performance, and deliver consistent products.
At Fox River Associates, we’ve seen first-hand how the right paper release liner or film release liner can determine the success of a die cut part. We understand the essential performance needs of release liners in die cutting, the industries that rely on them, the adhesives they pair with, and how to choose between paper and film release liners for your application.
Why Performance Matters in Die Cutting Release Liners
In die cutting and kiss cutting, a release liner does more than just protect adhesive, it enables the entire converting process. A poor-quality release liner can lead to misaligned cuts, adhesive transfer, or waste due to tearing or wrinkling. A high-performance liner, on the other hand, ensures:
- Dimensional stability: Consistent thickness and flatness for precise cutting.
- Controlled release levels: Reliable separation of the adhesive layer without damaging the die cut part.
- Surface uniformity: Smooth coating for even adhesive laydown and cutting accuracy.
- Durability: Strength to resist tearing during converting and end-use handling.
In kiss cutting, where only the adhesive and facestock are cut while leaving the liner intact, the liner’s ability to remain stable without distortion is especially critical. This allows converters to deliver parts on a sheet or roll for easy dispensing.

Applications That Rely on Die Cutting with Release Liners
Die cutting and kiss cutting are versatile processes, used to manufacture components in a wide range of industries. Each application places different demands on the release liner, particularly depending on the adhesive used.
Medical Devices
Release liners are essential in manufacturing medical tapes, wound care dressings, electrode assemblies, and diagnostic patches. These products often use medical-grade acrylic adhesives or silicone adhesives that require liners with consistent release properties and resistance to sterilization processes. Film release liners are frequently chosen here because they offer clean release, chemical resistance, and dimensional stability.
Automotive and Industrial Tapes
Foam tapes, vibration-dampening pads, and gasketing materials for automotive and industrial applications are produced through die cutting. Adhesives used include rubber-based adhesives for tack and quick stick, and high-performance acrylic adhesives for temperature and chemical resistance. Both paper and film release liners can be used depending on the thickness of the adhesive layer and the precision required in cutting.
Electronics and Electrical Assembly
Die cut parts for electronics, such as insulation pads, conductive tapes, and protective films, require release liners with excellent dimensional stability. Here, high-temperature acrylic adhesives or specialty conductive adhesives are common. Film release liners are often the preferred choice to ensure tight tolerances and clean edges.
Composites and Specialty Materials
In aerospace, marine, and sporting goods, composite prepregs and adhesive films are die cut for layup and assembly. These rely on thermoset adhesives or B-staged resins, where film release liners with high-temperature resistance and controlled release levels are critical.
Fox River Associates’ vast product offering serves these traditional and emerging market applications with both paper release liners and film release liners. Ready to learn more? Use the form on this page and our experienced team will promptly contact you to begin the discussion.
Choosing Between Paper and Film Release Liners for Die Cutting
Both paper and film release liners have strengths in die cutting applications. The choice depends on the material being cut, the adhesive chemistry, and the demands of the end-use application.
Paper Release Liners
Best for: General-purpose tapes, high-volume applications, labels, and graphics.
Paper release liners offer excellent dimensional stability in flat converting environments, provide good die cut support, and are cost-effective. They are widely used for kiss cut labels and stickers because they balance performance and economy. When paired with acrylic adhesives, paper release liners provide reliable release and handling for automated dispensing. Paper release liners for die cutting and kiss cutting are generally glassine paper release liners. Specialty applications may also include clay coated paper release liners.
However, paper release liners are less suitable for applications requiring high tear resistance or exposure to moisture and chemicals.
Film Release Liners
Best for: Medical devices, electronics, automotive, composites, and demanding die cut parts.
Film release liners, commonly PET, LDPE, HDPE, or PP, provide superior durability, clarity, and uniformity. They excel in kiss cutting because they resist tearing and allow precise removal of parts. They also handle high-performance adhesives such as silicones and withstand extreme temperatures, making them the preferred choice for critical applications where quality and performance cannot be compromised.
Converters often turn to film release liners from Fox River Associates when die cut parts must remain intact during dispensing or when the adhesive requires clean, consistent release levels.
The Role of Adhesive Chemistry in Die Cutting
The adhesive type often dictates the release liner choice. A few common pairings include:
- Rubber-based adhesives + Paper or Film liners: Suitable for tapes and gaskets where quick stick and flexibility are important.
- Silicone adhesives + Film liners: Used in medical devices and electronics where clean release and high performance are required.
- High-temperature adhesives + Film liners: Critical for composites and automotive parts.
- Acrylic adhesives + Paper liners: Ideal for labels, decals, and graphic applications.
By aligning adhesive chemistry with the right release liner substrate, converters can maximize efficiency and ensure consistent product performance.
