摘要

Packaging comprises container (A) and seal (B), welded together. Container comprises supporting layer (1), complexing layer pressure adhesive layer (3), and tearable welded layer (4). Container can also have binding layer (7), between supporting and complexing layers, if necessary. Seal comprises supporting layer (6), and welded layer (5). Seal can also have binding layer (8), between supporting and welded layers. Welded layer has resistance to tearing stronger than for tearable layer. Layers with weakest resistance to tearing are tearable layer and pressure adhesive layer. An Independent claim is also included for the method for preparing packaging.
