Polyethylene Embossed Foil
Rubber Separator for Tire Manufacturers, Vulcanized Rubber and Composite Materials
Tire and Vulcanized Rubber Production
The embossed polyethylene film is used as a release layer in the processing of rubber compounds, including:
- Tire production: inner liner, sidewall and rubber compound separator
- Easy storage for calendered rubber
- Separator for extruded rubber sheets
Composite MATERIALS : PREPREG SEPARATOR
In composite materials, the embossed polyethylene film is used in as a separator for prepreg materials. It prevents adhesion between the sheets of prepreg materials.
- Clean, defect-free prepreg sheets
- Easy to store, easy to detach
- Better prepreg quality
Benefits of Polyethylene Embossed Foil
Improved Product Quality
Protects from abrasion, contamination and foreign substances to ensure a smooth, uniform surface finish and enhance overall product quality
Enhanced Mold Release
The embossed surface creates a barrier that facilitates easy release, minimizing production downtime and waste.
Increased Efficiency
Streamlines the manufacturing process, reducing the need for additional release agents or manual interventions.
Cost-Effective Solution
In the rubber calendering process it is used as a separator of rubber sheets. It does not stick or melt and is easy to remove.

STORAGE
-
Storage conditions:
products must be stored in a dry area and should not be exposed to direct sunlight. Recommended storage conditions include temperatures between 10 °C and 25 °C and relative humidity between 40 % and 60 %. Any deviations in temperature and humidity may lead to altered product properties. - Shelf life: In cases described above regarding the recommended storage conditions, the estimated shelf life is 1 year from the date of production.

An environmentally-friendly alternative: polyester-based multilayer film
This new release liner is a stiff polyester-based multilayer film that is reinforced internally with a high tear resistance mesh; the film is then embossed in a second step to increase its release properties. With very high tear resistance, excellent mechanical qualities and release properties for processes that require a stiffer film.
High Mechanical Strength and Tear Resistance
Excellent release qualities for rubber
Costs less - can be reused 20-25 times more than conventional products
More environmentally friendly than standard polyethylene liner
Preserves fresh rubber sheets, without creases or deformation
No polluting substances, fraying or bagging
