EN 15385:2007 (E) 4 1 Scope This European Standard specifies a method for the determination of the strength of the head welding of flexible laminate tubes. 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:
