Environmentally friendly pressure sensitive adhesives to achieve strong peel strength by lower coating weight

This is a new environmentally friendly pressure sensitive adhesives has high adhesive strength even in a thin film that is 1/5th the thickness of conventional adhesives. Contributes to resource conservation and _CO2 reduction.

Advantages of thinner pressure sensitive adhesives

We have developed a new environmentally friendly pressure sensitive adhesives that has high adhesive strength even with a thin film thickness, which was difficult to do with conventional pressure sensitive adhesives.

Benefit 1: Contributes to resource conservation

Because pressure sensitive adhesives layer is thinner, it contributes to resource conservation, such as by reducing the amount of raw materials used during production.

*In case of pressure sensitive adhesives 25μm → 5μm

Benefit ②: Contributes to reducing CO ₂ emissions

Because pressure sensitive adhesives layer is thinner, CO ₂ from raw materials generated during production and CO ₂ generated from combustion during disposal can be significantly reduced.

• The CO ₂ emissions of the existing 25μm product is 0.283g/m2 as 100.
• Raw material procurement and combustion: We preferentially use IDEA version 2.2 [Climate Change IPCC 2013 GWP 100a], but some calculations are based on our own rules.

Development product data

We compared it with existing solvent-based acrylic pressure sensitive adhesives (our STD product).
Even with a film thickness of 5 μm, the developed product shows the same adhesive strength as the existing product with a film thickness of 25 μm.
