Specialty Sealant and Adhesive Resins and Additives
This chapter describes the comonomers used with olefin monomers to form copolymers with desirable functional properties for flexible packages. A particular group of comonomers, called alpha-olefins, containing four or more carbon atoms are used in special polymerization processes to produce linear polyethylene or polypropylene copolymers. Informed used of various copolymers can improve seal strength, durability, and heat resistance of packages. As a separate enhancement of functionality, various organic and inorganic compounds are blended into and then extruded with polyolefin films. The chemistry of comonomers and additives result in the many enhancements they provide to the chemically simple ...
