Low Environmental Impact Protective Film (Recycled Optical PET Protective Film)

Protective Tape With Low Environmental Impact, Aimed At Reducing CO2

This product uses materials that help reduce CO2 emissions. Use of recycled materials helps combine environmental friendliness and standard optical characteristics for optical applications. This product also offers affixing easiness equivalent to that of conventional protective tapes.

Product Characteristics

  • 1. Removable protective tape with a hard coating on one side, based on recycled PET
  • 2. Retains optical characteristics identical to regular optical PET film
  • 3. Reduces CO2 emissions during manufacture by more than 24% compared to regular PET film
  • 4. Features hard coating to conceal scratches and an adhesive layer with excellent air-expelling properties

Major Applications

  • Surface protection film for screens and backside of smartphones when shipped

2CO2 Reduction Achieved by Switching to Low Environmental Impact PET Protective Film

PET substrate usage (50 µm, 6.5-inch size) Annual CO2 reduction attributable to low environmental impact PET protective film
For 100 million smartphones 210 t (per year) 0.81 kg-CO2 × 210 t
→Reduction of 170 t-CO2 per year

*170 t of CO2 is roughly equal to the amount of CO2 absorbed by 12,070 trees over one year
