These are the advantages of self-adhesive films:
Our product range includes a wide variety of self-adhesive films. These feature beneficial properties such as:
- High adhesive strength: The right adhesive ensures reliable bonding of self-adhesive films to different materials.
- Quick application: Self-adhesive films are quick and easy to use, usually without the need for special tools.
- Cost and resource efficient: Compared to extensive renovations or replacements, self-adhesive films offer lower costs and better resource conservation.
- Custom design options: Self-adhesive films allow for great flexibility in design, with a wide range of styles and colors.
- Wear protection: Applied self-adhesive films can protect against scratches, wear, and UV radiation, especially in window or furniture applications.
- Energy savings: Special variants like anti-reflective or sun protection films can contribute to energy savings.
What types of adhesives are available?
Not only are the film types diverse, but the type of adhesive is also crucial in selecting the right product. The following table provides a direct overview of several adhesive types.
| Adhesive Type | Quick Tack | Final Adhesion | Temperature/UV Resistance | Flexibility | Tack / Final Adhesion / Curing | Applications |
|---|---|---|---|---|---|---|
| Acrylic (PSA) | Yes | High | High | High | Medium to high tack, high final adhesion; bonding strength increases with time, pressure, and temperature; no chemical curing required | Films, labels, vehicle graphics |
| Hotmelt (synthetic rubber adhesive) | Yes | Medium | Medium | Medium | High initial tack, immediate adhesion, no chemical curing required | Packaging, shipping labels |
| Butyl | No | Medium | High | Medium | No conventional tack, but high cold-flow capability, permanently plastic adhesion, no chemical curing required | Sealing applications, construction protection |
Self-Adhesive Film. Adhesive Types
Tack refers to the initial adhesion of a PSA (pressure-sensitive adhesive). It describes measurable adhesion after a very short contact time and light pressure. Final adhesion, on the other hand, refers to the bonding strength after full curing or a defined period of contact.
With pressure-sensitive adhesives (PSA), bonding is achieved through pressure and surface contact rather than chemical reaction.
Temperature, time, and pressure significantly influence the curing process and thus the final adhesion. Acrylic adhesives usually reach their full bonding strength after several hours to days, while hotmelts adhere instantly but are less temperature-resistant.
Where are self-adhesive films used?
Self-adhesive films are used across a wide range of industries.

| Building Technology & Trades | Sealing films, vapor barriers, protective films during installation work | Protection against corrosion and moisture, easy processing, environmentally friendly |
Peel Adhesion, Shear Strength, and Standards
In the field of self-adhesive films, there are several standards and requirements that are particularly relevant.
Self-Adhesive Film. Peel Adhesion, Shear Strength, and Standards
Peel Adhesion:
The force required to peel a tape off a surface. For temporary bonds (e.g., masking tape, labels), it should be strong enough to adhere, yet low enough to allow clean removal. For permanent bonds (e.g., double-sided tapes, mounting), high peel adhesion values are desired.
Shear Strength:
Shear strength refers to the adhesive’s resistance to “creep” or slippage under shear stress (force applied parallel to the surface). Shear strength is important for applications where the tape is under tensile stress or weight (e.g., splicing in the paper or printing industry).
Two key DIN standards in this context are DIN EN 1939 and DIN EN 1943.
DIN EN 1939 defines standardized testing methods for determining the peel adhesion of adhesive tapes. DIN EN 1943 describes the measurement of shear resistance under static load – that is, the adhesive’s resistance to slipping or creeping under a force acting parallel to the surface. Both standards help evaluate the adhesion and strength properties of self-adhesive products in a comparable way.
FAQ
How long do self-adhesive films last outdoors?
Depending on film material and adhesive type, between 3 and 10 years. UV- and weather-resistant variants are especially suited for long-term outdoor use.Are all films removable without residue?
Not all, this depends on the adhesive type, surface, and duration of application. We’re happy to advise you in selecting the best removable option.Can self-adhesive films be printed?
Yes, many films are suitable for digital or screen printing. Custom logo or graphic printing is also possible.What’s the difference between permanent and removable adhesive?
Permanent adhesives provide long-lasting bonding, while removable adhesives allow for later residue-free removal.What is meant by a release liner or release film on self-adhesive films?
Release liners are made of siliconized paper or siliconized PE/PP films and protect the adhesive layer until use.What is a fingerlift liner?
Fingerlift liners have an extended non-adhesive edge that makes peeling off the liner easier.
