The density of PET film is used to estimate PET base film GSM, roll weight, material yield, and construction consistency in protective film. A typical PET base film density is 1.38-1.40 g/cm3, with 1.39 g/cm3 often used as a calculation reference. For adhesive PET protective film, final values should be checked with total thickness, adhesive type, coating weight, liner structure, and sample testing before full use.
The density of polyester film helps estimate base film weight, GSM, roll yield, and finished protective film structure. This technical data sheet applies to PET / BOPET protective films, adhesive-coated polyester films, coated films, and roll converting checks where thickness, roll weight, peel behavior, clarity, and surface compatibility must be reviewed together. Typical values support calculation, while residue, edge lifting, and removal behavior need sample testing before full use.
Glass protection film for shipping helps reduce scratches, dust, fingerprints, packing friction, and repeated handling while finished glass moves from inspection through delivery. It can support flat glass, tempered panels, mirrors, glass doors, and coated or printed surfaces after compatibility testing. Film approval should not rely on thickness or tack alone. The practical decision is whether the film remains stable on the actual protected face, works with the shipping pack, tolerates the planned route and storage exposure, and can be removed under the agreed receiving conditions. The actual sample testing result should guide the final choice.
A clear glass protective film for sandblaster work should be evaluated as part of the masking process, not as a general glass cover. It is used on the glass workpiece during frosting, logo engraving, decorative sandblasting, lettering, and related abrasive surface processing. The main risks are contamination beneath the mask, weak stencil edges, abrasive undercut, film erosion, blurred pattern boundaries, difficult removal, and adhesive transfer. Selection depends on the actual glass surface, coating condition, pattern detail, tack, film body, cutting method, abrasive exposure, equipment setting, operator method, and the result of a representative sample trial.
A protective film that works well on a refrigerator panel at room temperature may behave differently after the panel is chilled, stored, handled, warmed and finally uncovered. This guide explains how to evaluate low temperature plastic film for refrigeration when temporary surface protection must remain stable through appliance production, cold storage and delivery handling. The main risks are poor initial wet-out, condensation, edge lifting, film stiffening, adhesive transfer, difficult peeling and hidden surface changes. Selection should be based on the real substrate and finish, the temperature at application and service, expected dwell time, handling route, humidity exposure and the planned removal temperature, then confirmed with representative sample testing.
Surface protection film application is the process of matching a temporary film or release structure with the real surface, working environment, and removal timing before full use. This solution supports plastic sheet processing, metal fabrication, appliance panels, glass handling, construction protection, adhesive coating, lamination, and die-cutting. The main risks are surface contamination, scratches, edge lifting, adhesive residue risk, haze, film tearing, and unstable liner removal. The core judgment is not thickness alone, but whether the selected PE film, PET film, or release liner can pass sample testing on the actual surface and process condition.
This technical data sheet explains how pet film density kg m3 supports BOPET base-film GSM, yield, and net roll-weight calculations. It separates PET carrier mass from adhesive, coating, liner, core, and packaging. Peel adhesion, optical appearance, edge stability, and removal behavior still require grade-specific data and actual-surface testing.
PET film refractive index is useful only when the measured layer and test conditions are clear. For transparent PET or BOPET, report wavelength, temperature, specimen direction, and method. A value near 1.60 at 589 nm is a reference for some polyester grades, but orientation and processing history can shift it. Confirm project specifications and finished adhesive-coated constructions on representative samples.
Polyester film optical properties describe how PET or BOPET film transmits, scatters, reflects, and changes visible light. Report haze, luminous transmittance, clarity, gloss, and color with thickness, coating condition, test side, and specimen structure. These data support clear protective film, coated PET, and applied-sample inspection. Peel behavior and post-removal appearance still require testing on the intended surface.
Surface protection film uses in industrial production extend from the moment a finished surface leaves coating, extrusion, polishing, or glass fabrication until the part is inspected and uncovered. The film can reduce exposure to metal chips, dust, fingerprints, tool contact, stacking friction, and transport handling, but poor matching can create edge lifting, bubbles, adhesive transfer, difficult removal, or visible surface change. The central decision is not simply film type. It is the combination of actual surface, coating condition, production route, application method, protection time, temperature, humidity, sunlight exposure, storage and transport conditions, and the result of a representative sample test.
Temporary glass protection film helps keep finished glass cleaner during construction, renovation, fabrication, transport, installation, and handover. It is used on windows, glass doors, mirrors, shopfront panels, partitions, and glazed parts where dust, paint overspray, mortar splash, fingerprints, packing friction, and cleaning abrasion may create visible defects. The right choice depends on surface type, coating condition, tack level, film visibility, protection time, temperature, humidity, sunlight exposure, handling method, and the actual sample test result before full use.
