Moisture Proof Black Polyester Film , Two Sides Gloss Polyester Film
Black PET Films/resist 150 degrees/matte/ frosted and haze/gloss on two sides
Product Description:
The product can resist 150 degrees for half an hour. This series of PET Films can be classified by surface: gloss on two sides, matte, frosted and haze. The degree of matte can reach 5 (0 when testing with water).
It can be used for shading, laminating, printing, diaphragm, insulating spacer and dust caps. We can customize our product based on your request. We sincerely welcome you to become agent of our products. Wholesale and retail are both accepted.
Specifications:
| Thickness | Width | Length | Paper Core |
| 4.5mic-250mic | 20-1500mm | 100-6000m | 76mm (3 inches) |
Characteristics:
1. This product is Environmentally-friendly, non-toxic, odorless and benzene-free. Solvent is not used during the production, therefore harmless to the Environment and people
2. Stable performance with good resistance to high temperature (150 degrees). We can produce product with surface that has tension and release force.
3. High efficiency. The production efficiency and the product quality can be largely improved when producing products like diaphragm and dust caps which has harsh temperature requirement (sometimes up to 190 degrees).
