Mask-Off Protex 8216-2L Low-Tack Polyester Film | 2 Mil Transparent Green | Boeing BAC 5034 | Airbus AIMS 12-6-001

A precision low-tack polyester film tape engineered for applications where light transmission, UV resistance, and high-temperature performance are critical. Unlike paper-based protective tapes, the 8216-2L's transparent polyester film allows visual inspection and process monitoring through the tape — without removal. Trusted by Boeing, Airbus, Lockheed Martin, Gulfstream, and Bombardier for protecting high-value surfaces in aerospace manufacturing and MRO environments. Protex 8216-2L by Mask-Off is a 2 mil tinted green polyester film with a low-tack, silicone-free acrylic latex adhesive and a flat release liner for converting and pre-cutting. Its durable polyester backing provides superior protection from abrasive and low impact damage, withstands temperatures up to 325°F, and is capable of prolonged outdoor exposure. The release liner makes it ideal for rotary die cutting and custom conversion into pre-cut protection pieces.

Key Features

• Transparent, UV resistant polyester film — Allows light transmission and visual inspection through the tape during any process without removal
• Low-tack acrylic latex adhesive — Gentle, repositionable hold that protects sensitive surfaces without leaving residue
• High temperature performance — Withstands temperatures up to 325°F without lifting, flagging, or adhesive transfer
• Prolonged outdoor exposure capable — UV resistant polyester maintains integrity during extended outdoor operations
• Die-cuttable flat release liner — Ideal for rotary converting and custom pre-cut protection pieces
• Silicone-free adhesive — No silicone contamination risk on critical aerospace and electronics surfaces
• Tinted green — Easy to see during application and removal; provides visual confirmation of coverage
• Boeing BAC 5034 & Airbus AIMS 12-6-001 approved — Meets Type IV, Class I, Grade A specification
