the layers of polymer outside the metallic foil has somewhat less effect on the body of the tube than does the thickness of the layers of metallic foil and the thickness of the layer of polymer between them as a point of reference conventional lead tube materials of the type associated with dispensing toothpaste and the like have a score bend value by this test of about 200 inch grams to about 350 inch grams since the samples used in testing score bend are 1 1 2 inches along the fold line this may also be expressed as about 133 inch grams per inch to about 233 inch grams per inch it has further been discovered that only the polymer outside the layers of metallic foil has a significant effect on the deadfold of the laminate tube of this invention and that the outside layer of polymer 24 has a greater effect on deadfold than the inner layer of polymer 20 this is a surprising result for which there appears to be no simple explanation fortuitiously the center layer of polymer 22 of the laminate which contributes significantly to its body as discussed earlier has little or no effect on the deadfold of the tube thereby allowing essentially separate determination of these two properties in the structure of this invention a number of tubes were constructed as described in table i the unfilled tubes were folded by hand through 180 u00b0 four 4 times placing the tube.
