Abstract: The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanureate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

Abstract translation: 本发明涉及聚丙交酯（PLA）作为挤出聚合物涂层在纸或板上的用途，用于生产容器和包装，其在炉子或微波炉中加热。 根据本发明，将多官能交联剂如三烷基异氰脲酸酯（TAIC）与PLA混合，并将挤出的涂层进行交联电子束（EB）辐射。 PLA可以原样使用或与另一种可生物降解的聚酯如聚丁二酸丁二醇酯（PBS）混合使用。 已经发现EB辐射改善了涂层对纸或基板的粘附性，涂层的热可伸缩性以及成品容器和包装的耐热性。
