Abstract: The process of the present invention provides a novel way of producing a masterbatch or polymer improver by heating a wax or polymer with a low temperature and mixing the molten wax with a additives, including pigments, at a low temperature above the congealing point of the wax to create a carrier material, in doing so this process will not degrade the pigment or additive which will be mixed together.

Abstract: A method of forming a bag is provided. The method includes providing an elongate tubular member (22) having opposed ends, at least one end (24) of which defines an open mouth (26). The method further includes folding opposed portions (28, 30, 32, 34) of the tubular member (22) to extend at least partially across the mouth (26). The method also includes positioning a panel (36) to extend across the opposed portions (28, 30, 32, 34). The method further includes securing the panel 36 and the opposed portions (28, 30, 32, 34) together thereby to close the mouth (26) at the at least one end (24) of the tubular member (22).
