It is applicable to flexible laminate tubes used for packing pharmaceutical, cosmetic, hygiene, fo

14、od and other household products. 2 Normative references Not applicable. 3 Principle The test for the strength of the head welding is used to show whether the body laminate deforms before becoming detached from the shoulder. 4 Test equipment 4.1 Cutting device 4.2 Tensile/compression tester EN 15385:
