While the molecular weight of these polyester polymers is high enough to provide satisfactory cohesion and adhesive bond strength, their melt viscosities are high enough to be used in conventional application equipment, such as gear pumps or pistons. Pumps, which are widely used in the packaging industry, cannot be implemented by low viscosity, polyolefin based adhesive.\r\\n\r\\nDecreasing the molecular weight of polyesters to a lower level drastically reduces the strength of the adhesive bond.\r\\nThe manufacturing process of packaging adhesives based on ethylene-vinyl acetate copolymer, paraffin wax or other wax additives are used to reduce the melt viscosity of the adhesive mixture. However, none of these conventional viscosity-reducing waxes can be used to provide the desired melt viscosity with polyester polymers because they are not highly compatible with polyesters and have low viscosities in two-phase systems.
