Abstract:

The tube has a non-metallized holographic decoration. This holographic decoration is an inner layer of the tube body which is of a laminate structure. The holographic film layer is a non-metallized layer to prevent the delamination of the tube body when the tube body is formed with an overlap seal. In an overlap seal an edge of the laminate film potentially will be in contact with the contents of the tube. A metallized holographic layer can react with the contents of the tube and cause a delamination of the film in the area of the seal and the consequent failure of the seal. The innermost layer of the tube body will be a layer that is bondable to an outermost barrier layer, and further that is bondable to the shoulder of the tube. It should be bondable to the innermost layer in order to form the longitudinal seal of the tube body. It should be bondable to the shoulder since the primary bond of the shoulder to the tube body is of the shoulder to the innermost layer of the tube body.
