AI Technical Summary

Technical Problem

Conventional packaging materials using a two-component reaction type adhesive face issues with slipperiness deterioration and physical property degradation during conveyance, particularly in laminates with a sealant layer, limiting their application configurations.

Method used

A reactive adhesive composition comprising polyol, polyisocyanate, acidic compounds, fatty acid esters, and/or fatty acid amides, which enhances adhesion strength and slipperiness by interacting with the sealant layer, preventing lubricant adsorption and migration of fatty acid esters/amides to maintain slipperiness.

Benefits of technology

The adhesive composition achieves both excellent adhesion strength and slipperiness, addressing the limitations of conventional laminates by improving interface interactions and reducing slipperiness loss.

Abstract

To provide an adhesive that has excellent bonding properties and exhibits excellent slipperiness when formed into a laminate, and a packaging material using the adhesive. [Solution] The above problem is solved by a reactive adhesive composition comprising a polyol and a polyisocyanate, wherein the reactive adhesive composition comprises an acidic compound and a fatty acid ester and / or fatty acid amide, and the polyol comprises one or more selected from the group consisting of polyester polyols, polyether polyols and polyurethane polyols.
