讨论了一种基于DURAFLEX* 聚丁烯聚合物（聚1-丁烯）与低密度聚乙烯、乙烯-乙酸乙烯酯共聚物（伊娃）和其他聚烯烃的共混物的可控热封技术。本发明描述了在用于柔性包装和封盖的各种基底上提供易打开或可剥离密封的各种系统。该混合物是100%固体（无溶剂），可以在标准设备上加工。剥离机制和变量，允许定制的密封强度进行了讨论。描述了用于各种应用的材料结构的示例，包括建议的制造技术。
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.
