Abstract

A flexible laminate tube includes a laminate and a sealing strip. The laminate includes at least two layers, an outer layer and an inner layer. The outer layer and the inner layer are non- sealable to each other and sealable to itself. The laminate is folded to overlap two longitudinally extending opposite edges thereof to configure a hollow body member. The sealing strip includes at least two layers, a first layer and a second layer. The first layer is sealable to the inner layer of the laminate, and the second layer is sealable to the outer layer of the laminate. The sealing strip is configured in-between two longitudinally extending opposite overlapped edges of the laminate such that the first layer faces the inner layer, and the second layer faces the outer layer to seal the two longitudinally extending opposite edges for configuring the hollow body member for making tube.
