Protective Film For Aluminum Profile

Clear Adhesive Film Company is a manufacturer of protective film for aluminum profile for temporary surface protection on long aluminum extrusion, window frame, and door frame profiles. It is used on anodized aluminum and powder coated aluminum during processing, storage, transportation, and installation. Low and medium adhesion grades help the film hold during handling, then peel away cleanly after typical 24-72h surface testing.

Product Overview

Protective film for aluminum profile is made for finished extrusion surfaces that are long, narrow, and irregular. Window frame and door frame profiles may include recessed grooves, curved corners, slim edges, and coated visible faces. These areas can be marked by aluminum chip rubbing, dust, fingerprints, pressure points, or scuffing between stacked profiles.

This aluminum extrusion protective film uses a flexible PE base film with controlled acrylic PSA. Standard thickness is 40-100 um, while 50-150 um can be selected for longer handling or higher puncture resistance. Roll length is commonly 100-2000 m. Custom slit width from 10-1560 mm can match the real visible face, reducing waste, exposed edges, and wrinkles during manual application or rubber roller lamination.

Adhesion should follow the actual finish. Anodized aluminum often works better with lower adhesion because peel force may rise after dwell time. Smooth powder coated aluminum can be tested with low or medium adhesion. Matte or lightly textured powder coated aluminum may need a medium grade for better contact. A good result means the film stays flat and removes at 5-40 C without obvious residue, ghosting, adhesive build-up, or surface marking.

Benefits

Protects visible frame faces from scratches, dust, fingerprints, aluminum chip rubbing, and handling marks.
Low / medium adhesion, typically 30-180 g/25 mm, helps match anodized and powder coated surfaces.
Custom slit width fits narrow edges, grooves, curved faces, and irregular extrusion sections.
Flexible PE film supports manual application or rubber roller lamination with less wrinkling.
24-72h dwell observation checks edge lifting, residue, ghosting, marking, and peel force increase.
60 C x 72h heat-aging checks can simulate warm storage or export transportation.

What should be tested before applying protective film on anodized or powder coated aluminum profiles?

Before wider use, the actual profile surface should be tested with small film samples. Anodized aluminum, smooth coating, matte coating, and textured coating can react differently to the same adhesive level. Low and medium adhesion samples should be applied to real window frame or door frame surfaces and observed for 24-72h. The check should include edge lifting, clean removal, adhesive build-up, peel resistance increase, ghosting, and surface marking. For warm storage or export projects, a 60 C x 72h heat-aging check gives a practical view of removal behavior.

Applications

Temporary surface protection for aluminum extrusion visible faces during cutting, assembly, and handling.
Window frame protection filmfor anodized or powder coated finished profile surfaces.
Surface covering for long door frame profiles before storage, transfer, and installation.
Protection for smooth, matte, or lightly textured powder coated aluminum frame surfaces.
Anodized aluminum protection filmfor low-adhesion covering where clean peeling is required.
Custom slit film for narrow edges, grooves, curved faces, slim exposed sides, and irregular sections.

How does custom slit width help protect long and irregular aluminum extrusion profiles?

Long aluminum extrusion profiles rarely have one flat surface. A window frame or door frame section may include exposed edges, grooves, curved corners, slim visible faces, and different coated areas. If the film is too wide, it may wrinkle or cover areas that do not need protection. If it is too narrow, part of the finished surface remains exposed. Custom slit width from 10-1560 mm allows the film to match the real contact area. With a typical +/-1 mm to +/-2 mm tolerance, the film can improve application stability, reduce edge lifting, and keep anodized aluminum or powder coated aluminum protected through machining, storage, transportation, and installation.

FAQ

What is protective film for aluminum profile used for?

It is used for temporary protection on aluminum extrusion, window frame, and door frame surfaces during processing, storage, transport, and installation.

What adhesion grade is usually used for anodized aluminum profiles?

Low adhesion is often tested first because anodized surfaces may show adhesion growth after 24-72h dwell time.

Can this film be used on powder coated aluminum window frames?

Yes. Smooth, matte, and lightly textured powder coated aluminum should be tested with low or medium adhesion samples.

Can the film width be slit for narrow extrusion faces?

Yes. Custom slit width can be made for visible faces, narrow frame edges, grooves, curved corners, and irregular profile sections.
