Ref. 791
A white polypropylene film designed for one of the most demanding applications: adhesion on tyres. The synthetic rubber hotmelt adhesive has a very high tack — 45 N loop tack — to bond to rough rubber from first contact. A practical alternative to barrier foil when outdoor durability is required.

Synthetic rubber adhesive · Very high tack · Tyres
Loop tack 45 N — bonds to rough rubber
The synthetic rubber adhesive is formulated to bond to tyres and rough surfaces where standard adhesives fall short.
No automatic dispensing
The high adhesive coat weight (50 ±5 g/m²) requires low cutting and rewinding speeds. Forcing the speed can cause the adhesive to bleed.
Multi-system printing
Compatible with thermal transfer, UV, solvent and water-based inks. If you need a compatible ribbon, ask us — we also supply it.
Alternative to barrier foil outdoors
Offers outdoor durability without resorting to more complex constructions. Shelf life 12 months at 20 °C / 50% RH.
High adhesive coat weight (50 ±5 g/m²): requires low speeds and controlled tension. Always validate under the real conditions of your process before starting production.
Why this material
Why high loop tack is the decisive criterion for tyre labels
The problem with standard adhesives
Tyre rubber is rough, flexible and sometimes carries traces of talc dust on the surface. A standard acrylic adhesive doesn't fill the rubber's pores quickly enough, and the label ends up peeling off during handling or transport. Synthetic rubber has the viscosity and flow needed to make good immediate contact.
Processing: going slow is the key
The high adhesive coat weight (50 g/m²) is what generates such high tack, but it's also what forces you to work with low cutting and rewinding speeds and controlled tension. Forcing the speed can cause the adhesive to bleed sideways. Not suitable for standard automatic dispensing. Always validate the processing conditions before starting production.
The values shown are typical manufacturer data. Verify under the real conditions of your process.
Key advantage
Loop Tack 45 N
45 N of loop tack on rough rubber is the figure that sets this material apart from a standard adhesive. A conventional acrylic adhesive won't bond to tyre rubber — this one bonds from first contact and doesn't come away even where the surface is irregular.
Combined with a peel of 23 N/25mm, it delivers permanent adhesion that withstands handling, transport and warehouse conditions.

Loop Tack (FTM9)
45 ±5 N/25mm
Initial grip on rough rubber. The figure that sets this adhesive apart from standard ones — 45 N is enough to stop it lifting during tyre handling.
Peel (AFERA 5001)
23 ±2 N/25mm
180° peel force. Permanent adhesion — the label doesn't come away on its own once applied. Combined with the loop tack, it gives very robust adhesion.
Adhesive coat weight
50 ±5 g/m²
A high coat weight, necessary for this level of tack. It means processing slowly: cutting and rewinding at low speeds, controlled tension. Not suitable for standard automatic dispensing.
Performance by use criteria
Excellent
Adhesion on rough surfaces
Loop tack 45 N and peel 23 N/25mm. Grips tyres and rough rubber where standard adhesives fail or lift during handling.
Excellent
Outdoor durability
A practical alternative to barrier foil when outdoor durability is required. Biaxially oriented PP film with good resistance to exposure.
Limited
Automatic dispensing
The high adhesive coat weight (50 g/m²) isn't compatible with standard automatic dispensing. Requires low cutting and rewinding speeds with controlled tension.
Limited
Long-term colour stability
Over time and with exposure, slight yellowing of the film may appear. Worth noting if long-term appearance is a priority requirement.
Multilayer composition
How it is built
Three layers: white PP film / synthetic rubber hotmelt adhesive / silicone-coated glassine liner. Total thickness: 172 µm ±5.
