摘要： A method for packaging plastic material using a film to surround the material, and more particularly to a method for packaging hot melt adhesives, the resulting package formed thereby, and the film composition used therein. The method is preferably a coextrusion process for packaging a pressure sensitive hot melt adhesive by extruding a hot melt adhesive through a die orifice, and coextruding a wax-based polymeric film to surround the hot melt adhesive. The coated adhesive may then be formed into individual packaged units having a finite size and shape. The polymeric film comprises a composition having at least 25% by weight of a wax material, an enthalpy of fusion of at least about 100 J/g, and an elongation value at break of at least about 100%. Any type of hot melt adhesive formulation can be packaged or surrounded by the polymeric film in the process. Also, the specific enthalpy of fusion desired and/or elongation value at break desired for the polymeric film can be obtained by blending an appropriate amount of partially crystalline ethylene-based polymer together with a thermoplastic elastomeric block copolymer and/or an ethylene based or propylene-based elastomer.

摘要： The present invention relates to hot-coextrudable hot-melt pressure-sensitive adhesives particularly suitable for the production of multilayer films intended for what are called “repositionable” packages that are opened and reclosed easily. The films used in these packages comprise at least three layers, namely an outer layer intended to be complexed thereafter, a sealing and separable layer, defining all or part of the internal surface of the package, and between them a hot-melt adhesive layer that joins them together. In this type of package, the adhesive plays an essential role insofar as, once the package has been opened by the end user, the quality of the reclosure and of the reopening will depend on the performance of the adhesive, which is of course a pressure-sensitive adhesive, that is to say an adhesive that adheres simply by manual pressure.
摘要翻译：本发明涉及特别适用于制造易于打开和重新闭合的所谓“可重定位”包装的多层膜的热共可挤出热熔压敏粘合剂。在这些包装中使用的膜包括至少三层，即其后要复合的外层，限定包装的全部或部分内表面的密封层和可分离层，以及它们之间的热熔粘合剂层，一起加入在这种类型的包装中，粘合剂起着至关重要的作用，一旦包装被最终用户打开，重新闭合的质量和重新开放的质量将取决于粘合剂的性能，这当然是压力敏感的粘合剂，也就是说通过手动压力粘附的粘合剂。
