High Heat Tape Company is a manufacturer of green polyester film tape for high-temperature industrial masking where coating accuracy, heat stability and clean removal are important. This single-sided tape uses a green PET/polyester film backing with silicone adhesive, with a typical total thickness of 0.055-0.085 mm. It is made for coating, painting, baking, powder coating, plating and anodizing support, and should be confirmed through sample bake testing on the actual production surface before full use.

Product Overview
This green polyester film tape is made for finishing lines that need a cleaner masking edge than ordinary paper tape can usually provide. The PET film backing, commonly supplied in 25-50 um film thickness, gives the tape good tear resistance and dimensional stability during short-term heat exposure. The silicone adhesive helps the tape stay in place during coating, painting and baking, then peel away more cleanly when the surface condition, bake temperature, dwell time and removal angle are controlled.
In daily production, this green PET film masking tape is often applied to metal panels, aluminum parts, powder coated components, plated areas and anodized sections. The translucent green color is not only for appearance. It helps operators see whether the masking line is straight, whether small areas have been missed and whether any tape remains on the part after baking or finishing.
Width and thickness should be selected according to the masking area. Narrow slit rolls are easier to apply around holes, slots, tight borders and curved edges. Wider rolls are better for larger flat areas where stable handling and smooth unwinding matter. High Heat Tape Company can slit rolls for different production needs, with typical slitting tolerance controlled within +/-0.3 mm for common widths. Clean slit edges and stable rewinding help reduce rough coating lines, edge lift and unnecessary application waste.
Applications
- Powder coating masking on metal parts, brackets, panels and fixtures
- Coating and painting bake processes where clean borders are required
- Plating support after surface and chemical compatibility testing
- Anodizing support where visible green masking helps process inspection
- Spray coating and industrial finishing lines using short-term oven exposure
- Masking of holes, slots, edges and small borders before heat processing
- Flat panel masking where thickness, slit width and removal stability need to be checked before production
Benefits
- Helps protect selected areas during coating, painting and short-term baking cycles.
- Silicone adhesive supports clean peel after heat when the surface and removal method are suitable.
- Visible green backing makes masking inspection easier before and after oven processing.
- PET film backing resists tearing better than paper masking tape during removal from heated parts.
- Clean slit edges help create neater coating borders around holes, slots and metal edges.
- Typical adhesion to steel can reach 5.5-7.5 N/25 mm, depending on thickness and adhesive coating weight.
- Sample bake testing helps check edge lift, curl, shrink, adhesive transfer and clean peel before production use.
- Plating and anodizing support should be confirmed through chemical contact and peel testing on actual parts.
What should be tested before using green polyester film tape in plating or anodizing work?
Before using green polyester film tape in plating, anodizing or other metal finishing work, it is better to test a small area on the real part rather than judging only from the temperature rating. The check should include adhesion on cleaned metal, edge holding near holes or coating lines, chemical contact behavior and removal after heat or process exposure. A 200-220 C reference bake value is useful, but it does not replace a production trial. After cooling, operators should look for film shrinkage, curling, edge lift and adhesive marks before approving the tape for batch masking.

How does green polyester film tape perform during coating, painting and baking cycles?
During coating, painting and short-term baking, green polyester film tape is expected to stay flatter and cleaner than ordinary masking tapes that may soften, tear or leave residue under heat. The PET film backing helps the tape remove in a more controlled way, while the silicone adhesive supports heat exposure during the bake cycle. For a sharper coating line, the tape should be pressed firmly along the border before parts enter the oven. After baking, the part should be checked for edge lift, adhesive transfer, curling, shrinkage and coating bleed, especially on textured metal, pretreated aluminum or parts with sharp bends.
FAQ
Is green polyester film tape suitable for powder coating?
Yes. It is commonly used for powder coating masking on metal parts that need a clean edge after the bake cycle. A sample bake test is recommended before full production.
Can this tape be removed cleanly after heat?
It is designed for clean peel after suitable heat exposure, but the result depends on surface condition, bake temperature, dwell time, cooling time and removal angle.
What thickness should be selected?
Thinner tape is better for small edges, narrow lines, holes and curved areas. Thicker tape is better for larger flat sections and stronger handling stability.
Can High Heat Tape Company slit the tape to narrow widths?
Yes. High Heat Tape Company can produce slit rolls for industrial masking needs, including narrow widths for holes, borders and precise coating lines. Slitting tolerance can be controlled within +/-0.3 mm for common widths.
