Surface Protection Films (LDPE)
Temporary protection for industrial surfaces. LDPE surface protection films protect delicate surfaces during manufacturing, transport, assembly, and installation. They provide a temporary barrier against scratches, abrasion, dirt, and chemical exposure. The films combine low-density polyethylene with a pressure-sensitive adhesive selected for the surface and application. They remain securely attached during processing and can be removed cleanly without leaving adhesive residue or staining.
Features and technical properties:
- Custom Gauge Options — LDPE film is available in thicknesses from 30 to 150 μm, with custom gauges available.
- UV Stabilization — Formulations support outdoor exposure periods ranging from short term to long term.
- High Mechanical Endurance — Withstands mechanical stress during handling, assembly, installation, roll forming, profile bending, and deep-draw thermoforming.
- Tailored PSA Systems — Acrylic, solvent-based, rubber, and custom PSA systems are available with different adhesion levels.
- Controlled Tack Range — Adhesion ranges from ultra-low tack for delicate optical surfaces to high tack for textured building panels.
- Degradation & Residue Defense — UV inhibitors help prevent film degradation, brittleness, and adhesive transfer during direct sunlight exposure.
- Clean Stripping Performance — Removes cleanly without leaving residue or visible marks on compatible surfaces.
Description
