Do you have any worries like this?

・ There is a request for biodegradation from a customer, and we want to make an all-biodegradable tape label together with the base material.
・The pressure sensitive adhesives currently under consideration does not have sufficient biodegradability.
・The pressure sensitive adhesives currently under consideration does not have sufficient biodegradability.
Our biodegradable pressure sensitive adhesives can help
What is biodegradable pressure sensitive adhesives?
- By using biodegradable raw materials as part of pressure sensitive adhesives raw materials, pressure sensitive adhesives has achieved biodegradability, which was difficult to achieve with conventional products.
- Our products have been confirmed to be highly biodegradable in a composting (high temperature and humidity) environment.
* ISO 14855-1 (JIS K6953-1) testing is conducted by an external organization. - By using it in conjunction with biodegradable base materials, it is possible to achieve biodegradation of the entire product.

Our product position
- Various biodegradation tests have been conducted, and we have confirmed that our biodegradable pressure sensitive adhesives has "compost decomposition" properties.
Various biodegradation tests
- Compost decomposition: Decomposes in a high temperature and humidity environment ISO 14855-1 (JIS K6953-1) → Our product
- Soil decomposition: decomposition in soil
- Aqueous decomposition: decomposes under freshwater conditions
- Marine biodegradation: decomposes in seawater
2-component strong adhesive type
- in a compost environment Confirmed biodegradability of 90% or more
Improved biodegradability from 60% of previously developed products! - Two-component strong viscosity type that uses a hardening agent.
