What is the difference between a low-density adhesive and a co-polymer adhesive?
A low-density adhesive (also referred to as homopolymer or monopolymer adhesive) is an adhesive requiring a higher laminating temperature in order to melt and bond. It is used to laminate uncoated paper products such as newspaper or construction paper. Co-polymer adhesive requires a lower bonding temperature, thereby speeding up the lamination process and reducing cooling requirements. These films adhere to the most difficult items including photographs, color-copier papers, and clay-coated surfaces. Co-polymer adhesives are so aggressive they even stick to some plastics, vinyls, and metals.
