Films Protective Company is a manufacturer of protective film for acrylic, made for temporary surface protection on cast acrylic sheet, extruded acrylic sheet, PMMA, and smooth PC plastic sheet. This PE film uses low or medium tack acrylic PSA to protect glossy, matte, polished, and sensitive sheet surfaces during machining, bending, forming trials, packaging, transportation, and installation. After proper use and 24-72h surface validation, it removes cleanly without adhesive residue, haze, ghosting, or visible whitening.
Product Overview
Acrylic sheet may leave extrusion or casting with a clean, bright surface, but marks often appear during later handling. Router beds, cutting tables, clamps, guide rollers, stacking boards, paper separators, and cartons can create light scratches, dust lines, fingerprints, drag marks, or pressure marks. A stable acrylic sheet protection film keeps the visible side covered without adding excessive adhesive stress to polished or sensitive panels.
This PE protective film for acrylic is a removable process mask, not a permanent coating. The PE carrier is commonly supplied in a 30-100 um range. Low tack grades, typically 20-80 gf/25 mm, suit high-gloss acrylic, mirror acrylic, matte acrylic, polished PMMA, and surfaces where peel marks must be minimized. Medium tack grades, typically 80-180 gf/25 mm, are used when stronger edge holding is needed during routing, drilling, repeated handling, or longer storage.
For reliable PMMA sheet surface protection, the sheet should be clean, dry, and free from oil, loose dust, static particles, and extrusion powder before lamination. Roll pressure should create full contact without stretching the film. Before bulk use, a 24-72h dwell test should check residue, ghosting, haze, whitening, and peel stress, especially on new sheets, frosted PMMA, coated panels, or parts needing heat bending or thermoforming checks.
Benefits
– Protects acrylic and PMMA surfaces from scratches, dust, fingerprints, drag lines, and handling marks.
– Softer adhesion helps reduce ghosting, haze, whitening, peel stress, and faint removal marks.
– Medium tack improves film stability during routing, drilling, workstation handling, and transport.
– Proper edge holding helps limit chip entry, dust entry, edge lifting, and film movement near cut lines.
– Clean-peel performance reduces wiping, solvent cleaning, rework, and inspection delays.
– Thickness, width, color, adhesion level, and printed masking can be adjusted for production lines.
What should be tested before keeping protective film on acrylic during CNC cutting, engraving, or heat forming?
Before approval, test the film on the actual cast or extruded sheet, not a generic plastic panel. A small trial should show whether the PE film stays flat during CNC cutting, engraving, routing, and hole drilling, especially around narrow strips, sharp corners, inner holes, and cut edges. Check edge lifting, chip entry, dust entry, film movement, and adhesive stability after vibration. For heat bending or thermoforming trials, heat, cool, and peel the sample to observe shrinkage, wrinkling, tearing, adhesive transfer, haze, or whitening. Good temporary acrylic surface protection should stay stable during processing and remove cleanly after fabrication.

How should low or medium tack acrylic PSA be matched to different acrylic sheet surfaces?
Low tack acrylic PSA is usually safer for high-gloss PMMA, polished acrylic sheet, mirror acrylic, matte acrylic, and other appearance-sensitive surfaces. These surfaces may look fine after lamination, but excessive adhesion can leave faint removal marks, ghosting, or surface shadow after several days of dwell. Medium tack film is more suitable for stronger handling, repeated workstation movement, longer storage, or heavier machining work. A well-matched acrylic fabrication masking film should consider sheet temperature, lamination pressure, dwell time, surface cleanliness, peel angle, and final visual inspection requirements.

FAQ
Is this film a permanent anti-scratch coating?
No. It is a temporary acrylic fabrication masking film for processing, packing, transport, and installation.
Which adhesion is better for high-gloss acrylic sheet?
Low tack is usually preferred for high-gloss, polished, matte, mirror, or sensitive acrylic surfaces.
Can it stay on during CNC cutting and engraving?
Yes. The correct adhesion grade helps the film stay flat during cutting, routing, drilling, and engraving.
Will it leave residue after peeling?
It is designed for clean removal, but 24-72h testing on the actual acrylic sheet is recommended before bulk use.
