Protex 8216-2L is a 2 mil transparent, green-tinted polyester film with a low-tack, silicone-free acrylic adhesive — the see-through aerospace protective film qualified to Boeing BAC 5034 Type IV, Class 1, Grade A and Airbus AIMS 12-6-001 for protecting acrylic, polycarbonate, glass, metal, and painted surfaces. Because the film is transparent, parts can be inspected through it without removal, and it withstands temperatures up to 325°F with UV resistance for extended protection. The 1–3 oz/in adhesive removes cleanly, and a flat release liner makes it die-cuttable into custom shapes. Available in tinted green in 12", 16", 24", and 48" widths on 100-yard rolls.
Manufacturer's Certification included FREE of charge.

Frequently Asked Questions
What is Protex 8216-2L used for?
Protex 8216-2L is a transparent protective film for acrylic, polycarbonate, glass, plastics, metals, and painted surfaces during fabrication and MRO. Because it's see-through, parts can be inspected without removing the film.
How is Protex 8216-2L different from Protex paper grades?
Protex 8216-2L is a 2 mil transparent polyester film, not a latex-saturated paper. It adds visibility, low tack, UV resistance, and a 325°F rating, while Protex 5, 10V, and 20V are opaque papers built for scratch, abrasion, and impact protection.
Where is Protex 8216-2L used on Boeing aircraft?
Mask-Off reports existing Boeing applications for Protex 8216-2L at Charleston, Renton, and Everett, including flight deck windows and galley countertops.
Which BAC5034-4 tables list Protex 8216-2L?
Mask-Off lists Protex 8216-2L in BAC5034-4 Table II — Type V storage protection (aluminum, BMS 15-12 Type I, Class 1 coated); Table III — transportation protection for detail parts, metal surfaces with organic coatings, and assemblies (bare and painted aluminum, BMS 15-12 Type I, Class 1 coated aluminum, and metal surfaces with organic coatings); Table IV — Type VII manufacturing protection for Class 1 mechanical processing conditions, machining, and shop handling.
Is Protex 8216-2L low-tack and residue-free?
Yes. Its low-tack, silicone-free acrylic adhesive (1–3 oz/in) gives a gentle hold and removes cleanly.
What temperature can Protex 8216-2L handle?
Protex 8216-2L is rated for temperatures up to 325°F, so it can stay in place through high-temperature masking and processing.
Is Protex 8216-2L flame retardant and aircraft approved?
Protex 8216-2L is a temporary process protection film, not a fly-away part, so it is not sold as a flame-retardant interior tape. It is qualified to Boeing BAC 5034 Type IV, Class 1, Grade A and Airbus AIMS 12-6-001.
What sizes does Protex 8216-2L come in?
Protex 8216-2L comes in tinted green in 12", 16", 24", and 48" widths on 100-yard rolls, and its flat liner makes it die-cuttable.
Can Protex 8216-2L be used outdoors?
It is UV resistant, but Mask-Off recommends testing before outdoor exposure, and before use on copper, brass, or anodized aluminum or where chemical resistance is needed.
Is Protex 8216-2L solvent resistant?
Mask-Off's test results show excellent resistance to toluene, MEK, alcohols, and trichloroethylene. Chemical resistance should still be confirmed by testing before use.
