Films Protection Company is a manufacturer of Heat Resistant Transparent Film for PET-based insulation, masking, overlay, temporary surface protection, and converted PET part supply. It covers clear PET film roll, self adhesive PET film, silicone-coated PET adhesive film, linered adhesive film, and die-cut PET components for controlled heating stages. Specifications can be matched to PET thickness, adhesive structure, liner format, transparency, peel after heating, surface compatibility, and equipment use.

Heat Resistant Transparent Film is used when production teams need clear PET film to protect, mask, insulate, or cover a visible working area. It may be supplied as a plain PET layer, adhesive film, silicone adhesive masking film, or drawing-based PET component. A suitable grade should stay flat, remain clear, avoid marks, and run smoothly into slitting, lamination, die cutting, or application.
A practical specification starts with the real working surface. Surface material, coating type, dwell time, pressure, cooling method, and removal angle can change peel force, haze, ghosting, or adhesive transfer. For repeat supply, retained sample comparison and agreed test conditions should be confirmed before sampling.
Product Series | Covered Products | Best-Fit Procurement Use |
Clear PET Film Roll | Transparent PET in roll or sheet form | Insulation overlay, spacer, gasket, non-adhesive protection |
Self Adhesive PET Film | Clear PET with adhesive and optional liner | Temporary positioning, display protection, process cover film |
Silicone-Coated PET Adhesive Film | PET carrier with silicone adhesive layer | Controlled heated masking, clean peel, electronic protection |
Converted PET Part | Die-cut insulation piece, hole part, pull-tab mask, shim | Drawing-based assembly, pilot die-cut lot, equipment-fed placement |
Plain PET film is used when adhesive contact is not allowed. Self adhesive PET film keeps material in place before inspection, heating, or assembly. A silicone adhesive PET structure is selected when ordinary adhesive may soften or leave marks. For converted PET parts, holes, tabs, liner release, part picking, and tool clearance should be checked early.
Select by working condition, not only the highest temperature number. For insulation or overlay, PET thickness, flatness, edge quality, and clarity may matter more than tack. For removable heated masking, 180-degree peel adhesion after heating, residue inspection, haze change, and cooling-stage removal should be reviewed before approval.
Selection Comparison | Recommended Structure | Key Check Before Sampling | Mis-selection Risk |
Clear insulation or overlay | Plain clear PET film | Thickness, clarity, edge quality | Using adhesive film when not needed |
Temporary heated masking | Silicone-coated PET adhesive film | Dwell time, surface temperature, peel after cooling | Selecting by initial tack only |
Automatic die-cut application | Linered converted PET part | Liner release, part picking, winding direction | Skipping equipment feeding test |
A trial roll or pilot die-cut lot should be tested on the same surface and equipment to detect edge lifting, shrinkage, liner release change, roll blocking, and surface ghosting.
Selection should start from actual working conditions. For insulation, confirm PET film thickness, dielectric needs, edge coverage, and whether the part will be wrapped, laminated, or die cut. For masking and overlay, transparency helps production teams see alignment marks, holes, display surfaces, or coated areas. When temporary adhesion is required, self adhesive PET film with silicone adhesive is often selected for better heating stability and cleaner removal. For converted PET parts, drawing tolerance, liner format, tab design, waste-removal method, and automatic feeding compatibility should be confirmed before batch production.
Item | Typical Range / Customizable Value |
Base Material / Thickness | Clear PET film substrate, typical 25-250 um by application review |
Adhesive / Liner | Silicone adhesive for heated use, acrylic option for lower-temperature use, PET or paper liner |
Short-Term Temperature Reference | Typical 120-230 C by grade, dwell time, surface, pressure, and removal condition |
Transparency / Surface Check | Light transmission, haze, ghosting, yellowing, and surface compatibility checked if required |
Peel / Residue Check | Initial peel, 180-degree peel after heating, residue after cooling and removal |
Converted Format | Roll, sheet, die-cut part, hole part, pull-tab part, gasket, spacer, shim |
Equipment / Quality | Roll flatness, liner release, part picking, feeding stability, COA, SDS, retained sample |
Films Protection Company can adjust PET thickness, total thickness with adhesive, adhesive type, peel level, liner, roll width, roll length, sheet size, core size, and roll diameter. For converted parts, confirm die-cut shape, hole position, tab design, tolerance, liner format, waste-removal method, and winding direction.
For equipment use, confirm manual application, roller lamination, die cutting, or automatic pick-and-place requirements. For heated use, provide surface material, heating time, pressure, cooling method, and removal timing. For quotation and sampling, share roll width, roll length, application surface, test temperature, expected monthly volume, packing preference, and whether the first approval should be supplied as a trial roll, sheet sample, or pilot die-cut lot. For visible surfaces, keep a retained sample for haze, peel, residue, and color comparison.
Transparent PET silicone adhesive film should be tested before bulk use whenever heat, pressure, coating, or removal timing may affect performance. The same material can behave differently on stainless steel, coated aluminum, glass, PC, PMMA, painted plastic, or display surfaces. A sample test should check heated process window, dwell time, cooling condition, peel force, adhesive transfer, haze change, edge lifting, bubble marks, and surface ghosting. If the film will be die cut or equipment-applied, also check liner release, part picking, roll flatness, and feeding stability.
Confirm whether the value refers to base PET thickness or total structure thickness including adhesive and liner. For self adhesive PET film, adhesive coat weight, liner thickness, and feeding behavior should be checked together.
Silicone adhesive is usually preferred for heated masking or removal after cooling. Acrylic adhesive may work for lower-temperature protection, but it should not be selected only by cost without residue, peel, and surface-mark testing.
Check 180-degree peel adhesion, residue, haze change, ghosting, edge lifting, shrinkage or curling, and clean removal after cooling. Use the production surface, real dwell time, expected pressure, and planned removal method.
Confirm roll width, roll length, sheet size, die-cut drawing, tolerance, liner format, tab design, winding direction, packing quantity, and sample approval standard. A trial roll or pilot die-cut lot is recommended when the structure or part shape is new. Lead time is affected by adhesive structure, liner availability, slit width, die tooling, and whether pilot approval is required before repeat production.
