摘要： A generally transparent flexible packaging structure having an anti-transfer layer which, in a closed and sealed package, is at or close to an interior surface of the package. A contained food product in the package has a tendency to deposit a food product component on the interior surface of the packaging material and to thereby have a visually obscuring affect on transparency of the packaging structure. Anti-transfer material in the anti-transfer layer migrates to the interior surface of the package and interacts with the visually-obscuring component of the contained food product, thereby to attenuate or eliminate the visually obscuring effect of such component. Preferred primary polymer in the anti-transfer layer is EVA. Preferred anti-transfer materials include fatty acid esters and other amines and derivatives. The invention includes certain aspects of multiple layer packaging structures, closed and sealed packages, and methods of packaging food product.
摘要翻译：一种通常透明的柔性包装结构，其具有在封闭和密封的包装中处于或接近包装内表面的抗转移层。包装中包含的食品具有将食品成分沉积在包装材料的内表面上的倾向，从而对包装结构的透明度具有视觉模糊的影响。抗转移层中的抗转移材料迁移到包装的内表面并与所含食品的视觉上模糊的组分相互作用，从而减弱或消除这些组分的视觉模糊效果。抗转移层中优选的主要聚合物是EVA。优选的抗转移材料包括脂肪酸酯和其它胺和衍生物。本发明包括多层包装结构，封闭和密封包装的某些方面以及包装食品的方法。

摘要： A method and apparatus for sizing steel joint rings welded to the ends of cylindrical pipes. A substantially closed integral ring member is used within a joint ring and expanded outwardly thereagainst. A force applying means, such as a hydraulic cylinder, applies a controlled outward force to the ring member which distributes the force in a radially outward direction against the inner circumference of the joint ring for the desired sizing thereof.

摘要： Containers are disclosed, as well as multilayer films used in such containers, which advantageously maintain a high seal strength even after being subjected to hot-fill conditions for sterilization. These microwavable/ovenable containers (10) and multilayer films are also beneficially self-venting upon exposure to microwave heating, when the internal container pressure exceeds a threshold value. These self-venting containers are also automatically self-sealing after the self-venting feature has ruptured and the container has cooled to room temperature. The self-venting self-sealing nature of these containers arises from particular film and sealing characteristics, in which the seal width differs in defined, self-venting self-sealing seal regions (13A), relative to non-venting seal regions (13B) of a given peripheral seal. Particular film materials and structural geometries of the self-venting self-sealing seal regions can be used to improve the location of venting and control of the vented gases, as well as, the resealability of the containers.
摘要翻译：公开了容器，以及在这种容器中使用的多层膜，即使在经受用于灭菌的热填充条件之后，其也有利地保持高的密封强度。当内部容器压力超过阈值时，这些微波/可烘烤容器（10）和多层膜在暴露于微波加热时也是有利地自发的。这些自放气容器在自通气特征破裂并且容器冷却至室温后也自动自密封。这些容器的自通气自密封特性源于特定的膜和密封特性，其中相对于非排气密封区域（13B），限定的自排气自密封密封区域（13A）中的密封宽度不同，给定的外围密封。自排气自密封密封区域的特殊薄膜材料和结构几何形状可用于改善通风气体排放和控制的位置以及容器的再密封性。
