Abstract

A controllable heat sealing technology, based on blends of DURAFLEX* poly butylene polymer (poly-1-butene) with low density polyethylenes, ethylene-vinyl ace tate copolymers (EVA) and other polyolefins is discussed. A variety of systems are described which provide easy-open or peelable seals on various substrates for both flexible packaging and lidding. The blends are 100% solid (solvent free) and can be processed on standard equipment. The peeling mechanism and variables which permit tailoring of seal strength are discussed. Examples of material structures for various applications are described, including suggested fabrication techniques.
