Abstract: Improved packages and methods for constructing packages are provided that reduce or prevent leakage into or out of the package. In particular, the package includes a base member and a lidding member with a reinforced perimeter portion that blocks channels that may form at the interface between the base member and the lidding member from extending to the edge of the base member, such that, e.g., liquids have no path to the package exterior. The perimeter portion may be a thicker region of a first film of the lidding member (e.g., a polyethylene emulsion), or the perimeter portion may be formed using permanent adhesive. Frangible layers and/or cut lines may be defined in the material of the base member or the lidding member to allow a controlled break to occur when the lidding member is peeled away from the base member to provide access to the package contents.

Abstract translation: 提供了改进的用于构建封装的封装和方法，其减少或防止泄漏进入或流出封装。 特别地，该包装包括基部构件和封盖构件，其具有加强的周边部分，其阻挡可在基底构件和封盖构件之间的界面处形成的通道，以延伸到基座构件的边缘，使得例如， 液体没有到包装外部的路径。 周边部分可以是封盖构件的第一膜（例如，聚乙烯乳液）的较厚区域，或者周边部分可以使用永久粘合剂形成。 可以在基底构件或封盖构件的材料中限定易碎的层和/或切割线，以允许当封盖构件从基底构件剥离以提供对包装内容物的接近时发生受控的断裂。
