摘要： The present invention is directed to manually openable heat-resistant packages for containing a product that include a thermoformed tray having a product receiving area and a sealing flange endowed with sufficient heat resistance to withstand the cooking and/or pasteurization/sterilization conditions required to produce a ready-to-eat packaged meal. The tray comprises a bulk layer, and a heat sealing layer in direct contact with the bulk layer. The inventive packages also include a flexible transparent lidding film covering the thermoformed product receiving area comprising a heat sealing layer. The package includes a hermetic seal comprising a perimeter heat seal which circumvents the thermoformed tray formed by heat sealing a portion of the heat sealing layer of the lidding film to the sealing flange of the tray. Only the heat sealing layer of the tray is readily frangible and renders the heat seal manually peelable.
摘要翻译：本发明涉及用于容纳包含具有产品接收区域的热成型托盘和具有足够的耐热性的密封凸缘的产品的可手动开封的耐热包装件，以承受制造所需的烹饪和/或巴氏灭菌/灭菌条件即食包装餐。托盘包括本体层和与本体层直接接触的热密封层。本发明的包装还包括覆盖包含热封层的热成型产品接收区域的柔性透明封盖膜。该包装包括气密密封件，其包括周边热封，其围绕通过将封盖膜的热封层的一部分热封到托盘的密封凸缘而形成的热成型托盘。只有托盘的热封层容易易碎，并使热封手动剥离。

摘要： The present invention is directed to rigid or semi-rigid trays having a bulk layer comprising a crystalline aromatic polyester and a capping layer which is in direct contact with the bulk layer. The capping layer comprises a copolymer having a first structural repeating unit of ethylene and a second structural repeating unit selected from the following: (i) an acrylate-based moiety: fit) at least 12% by weight relative to the total weight of the copolymer of vinyl acetate; and (iii) an anhydride or carboxylic acid. It has been discovered that the bulk layer and the capping layer of the present invention can be readily co-extruded together and have sufficient bond strength to each other despite their chemical dissimilarity. In some preferred embodiments, the capping layer acts as a heat seal layer and is formulated to heat seal to conventional polyolefin-based lidstock.

摘要： A packaging film is described. The packaging fi!m comprises a first layer comprising thermoplastic polyurethane eiastomer. The thermoplastic polyurethane elastomer comprises a thermoplastic polyeiher polyurethane elastomer or a thermoplastic polyester polyurethane elastomer. The thermoplastic polyurethane elastomer has a shore A hardness in accordance with DtN ISO 7819-1 (3s) of equal to or greater than about 35. The first layer is an inner layer of the packaging film. The packaging film also comprises a second layer comprising a first tie material. The second layer is directly adjacent the first layer. The packaging film also comprises a third layer comprising ethylene vinyl alcohol copolymer. The third layer is positioned inferior to each of the first layer and the second layer. Various embodiments of the packaging film are also described.
