Adhesives
This chapter describes the chemical composition of traditional flexible packaging adhesives. These materials have the demanding challenge to adhere strongly to two different substrates and provide enough cohesive strength that the multi-layered lamination is able to integrate the desired properties of its individual components. The chemistry of adhesives is typically rather complex in order to deliver all of this functionality. Their curing process usually involves chemical reactions that bond one type of chemical to another forming a nonreversible solid. The usual type of this adhesive is based on urethane chemistry that is able to form polymeric materials from monomers at atmospheric pressure and near room temperatures. Alternate ...
