Clear Adhesive Film Company is a manufacturer of Metal Processing Protective Films for stainless steel sheet, colored metal sheet, painted metal, aluminum sheet, pre-coated metal, and sheet metal fabrication. This category covers protective films used during laser cutting, bending, punching, stamping, forming, roll forming, coil processing, storage, transport, and surface handling. Film grades can be selected by metal finish, process pressure, cutting method, adhesion level, color, roll width, protection period, and final removal condition.
Showing the single result
Laser film for sheet metal is made for stainless steel processing where cutting quality and surface appearance must be controlled together. It is laminated before laser cutting and may stay on parts during bending, punching, drilling or forming.
The difficult zones are usually piercing holes, dense hole patterns, narrow slots and sharp internal corners, not only long straight cuts. A grade that performs well on simple cutting may still lift near a piercing point or shrink along the kerf edge. For BA and mirror stainless steel, residue, ghosting, peel shadow and black marks should be checked after cutting and again after the agreed dwell time.
This category covers metal sheet protective film, stainless steel protective film, colored metal protective film, painted metal protective film, aluminum sheet protective film, pre-coated metal protective film, coil processing film, forming film, bending film, stamping film, and laser cutting film. Laser Film For Stainless Steel should remain as the specific product for laser cutting, while Metal Sheet Protective Film should cover wider sheet and coil processing protection.
For laser cutting stainless steel with film, grade selection should consider cutting speed, gas pressure, piercing program and post-cut work. Medium tack suits BA or mirror finish where low peel shadow matters. Higher tack suits brushed and 2B surfaces when dense holes, long slots or higher gas pressure increase lifting risk.
Product Series | Main Use | Selection Notes |
CO2 Laser Process Film | CO2 laser cutting stainless steel with film | Visibility, kerf edge check and clean removal |
Fiber Laser Process Film | Fiber laser protective film for 2B or brushed stainless steel | Bubbling, heat-edge and cut-edge stability test |
Transparent / Black-White Film | Inspection or directional handling | Grain check, roll-side control, arrow direction and batch code |
Medium / High Tack Grade | BA, mirror, brushed or 2B stainless steel | Balance peel shadow, gas lift and removal force |
Start with the metal surface and processing route. Mirror, BA, and polished stainless steel normally need lower-residue adhesive to reduce peel marks and ghosting. Brushed, hairline, satin, and textured surfaces may need stronger wet-out and edge holding. Painted metal and colored coated sheet should be tested for coating hardness, surface energy, storage time, and removal behavior. For cutting and light handling, thinner grades may be enough. For bending, punching, stamping, deep drawing, or long transport, thicker film and stronger tear resistance may be required. Laser cutting grades should be tested separately for bubbling, kerf-edge lifting, adhesive transfer, black marks, and one-piece removal.
Film grade should be confirmed on the actual metal finish and through the planned cutting or forming route. For preparation, line trials, storage control, and final removal across several workstations, review the industrial surface protection workflow. The category can then remain focused on metal finishes and process-film options.
For finished stainless steel parts, a stainless steel protective wrap removal guide can help packaging teams reduce residue, scratching, and film-tear complaints after processing.
Material / Adhesive Option | Suitable Focus | Advantage | Risk to Confirm |
PE + rubber adhesive | CO2 or fiber cutting | Strong holding | Residue on mirror finish |
Co-extruded PE + modified adhesive | Dense holes, higher gas pressure | Balanced peel | Edge shrinkage, gas lift |
Transparent / black-white PE | Inspection or direction control | Defect check, roll recognition | Heat-edge and winding direction |
Medium / high tack adhesive | Different finishes | Match surface and process load | Lifting or high removal force |
Before batch use, test the film on the actual stainless steel grade, finish and machine setting, not only by hand adhesion. Brushed stainless steel, 2B, BA and mirror surfaces react differently during piercing and narrow-slot cutting. A stable straight-cut result may still fail near small holes or sharp corners. If the sheet continues into bending, punching or forming, record cut-edge lifting, forming cracks, film tearing, residue after peeling and one-piece removal.

Clear Adhesive Film Company can adjust thickness, tack level, width, length, color, printing, winding direction, core size and slit tolerance. Direction arrows, batch codes or removable warning print can support film-side recognition.
For repeat production, share stainless steel finish, sheet thickness, laser type, assist gas, cutting speed range, piercing pattern, removal time and whether the film remains during bending or punching. Retained samples help compare tack, unwind force, flatness, residue and peeling.
Adhesion should be selected by process risk and surface sensitivity together. Brushed and 2B stainless steel need enough tack to resist film pullback, bubbling and lifting during CO2 or fiber laser cutting. BA and mirror stainless steel need careful control because excessive tack or heat-affected adhesive can create peel marks, adhesive shadow, ghosting or residue. A practical range is 60-100 um film thickness with grade-dependent peel adhesion around 2.0-4.5 N/20 mm, confirmed by actual sheet surface, dwell time, speed and gas pressure.
Some grades can be tested for both, but not assumed. Confirm speed, gas pressure, sheet thickness, surface finish and assist gas type.
Bubbling often appears when assist gas enters between the film and steel surface during piercing, dense-hole cutting or narrow-slot cutting.
It can be suitable only after laser cutting tests on the actual mirror or BA stainless steel surface. Controlled tack, clean removal, residue inspection and low peel shadow should be confirmed after peeling.
Useful details include laser type, stainless steel finish, sheet thickness, speed, gas pressure, piercing design, roll width, lamination method and removal time.
