摘要： A patterned metal foil/substrate laminate wherein the pattern is formed by laminating a sheet of metal foil to a substrate by applying an adhesive between the metal foil and substrate in a predetermined pattern which defines areas where adhesive is present and areas where no adhesive is present, cutting the metal foil, as by rotary die cutting or laser cutting, in a pattern which corresponds to the boundaries of the adhesive-containing areas and removing the areas of metal foil which are not adhesively adhered to the substrate. Particularly where the laminate is intended for microwave packaging, the laminate further includes a sheet of barrier layer material, preferably polymer film, laminated to the patterned metal foil layer. The polymer film layer-containing laminate can be formed into a container for packaging food intended for heating in a microwave oven, the container having at least one section, corresponding to the areas of the laminate from which metal foil was removed, that is substantially transparent to microwave energy and at least one section, corresponding to the foil-containing areas of the laminate, that is opaque to microwave energy for shielding food adjacent to the opaque section. Preferably, the metal foil is aluminum foil, desirably unannealed aluminum foil, and the substrate is selected from paper, coated or uncoated paperboard and polymer film.
摘要翻译：图案化的金属箔/基板层叠体，其中，图案通过在限定存在粘合剂的区域和不存在粘合剂的区域的预定图案中在金属箔和基板之间施加粘合剂而将金属箔片层压到基板上而形成通过旋转模切或激光切割切割金属箔，以与含粘合剂的区域的边界相对应的图案，并且去除不粘附到基底上的金属箔的区域。特别是在层叠体用于微波包装的情况下，层压体还包括层压到图案化金属箔层上的阻挡层材料片，优选聚合物膜。含有聚合物膜层的层叠体可以形成为用于包装用于在微波炉中加热的食品的容器，该容器具有至少一个部分，对应于去除金属箔的层压体的区域，其基本上是透明的微波能量和对应于层压体的含箔区域的至少一个部分，其对于微波能量是不透明的，用于屏蔽邻近不透明部分的食物。优选地，金属箔是铝箔，期望为非退火的铝箔，并且基材选自纸，涂布或未涂布的纸板和聚合物膜。
