ABSTRACT:
It has been found that fluid, semi-fluid, plastic products as well as powder or granular products packed in plastic tubes have caused great problems in tropical countries due to the change in temperature between day and night. In some cases the products have expanded and burst open the closure of the plastic tube so that the contents ran out or, due to their constituents, the products have caused deterioration of the protective properties of the plastic tube. By choosing a plastic tube or olefin plastic and sealing said plastic tube with closures of olefin plastic, as well as orientating the plastic molecules in the tube in both axial and radial direction, a plastic seal is obtained which is not affected by the products enclosed and which also resists expansion of the products without rupturing.
