KANTUNG-KANTUNG DAN BAHAN-BAHAN PENGEMASAN YANG DAPAT DISOBEK DENGAN MUDAH

摘要

A multi layered packaging material (10) comprises a first inner layer C and a second outer layer A. The inner layer has a line of weakness 34 extending there along while the second outer layer A is substantially intact along the line of weakness. In the packaging material 10, the line of weakness is formed by two pieces of material C1, C2 with their edges in substantial abutment, the abutted edges creating the line of weakness. Bags 20, 30, 40, 60, 70, 80, 90, 100, 130, 140, 150 may be formed from the packaging material. However, the bags so formed are not limited to having the line of weakness created by abutting edges in the inner layer C.
