A method of manufacturing a lined folding carton is provided for use primarily as packaging or as containers for liquids and moist, wet and high-fat greasy products. The method comprises providing a cut and creased and/or scored blank 2 and a predetermined length of a layflat tubing 16. One or more patches of adhesive 18, 18A are applied to parts of the blank adapted to form at least a first of opposing first and second sides of the carton when erected. Thereafter, either one side of the length of layflat tubing is adhered to one or more of the patches of adhesive on at least that part of the blank adapted to form said first side of the carton and one or more further patches of adhesive are applied on parts of the blank adapted to form at least the second side of the carton when erected or vice versa. A part of the blank adapted to form the second side of the carton is then folded over to oppose the first side and adhered either directly or indirectly to an opposite side of the layflat tubing. Edges of the blank are then secured together to form a folded carton. When such a folded carton is erected, the fact that opposite sides of the layflat tubing are adhered directly or indirectly to opposing sides of the carton means that the tube opens out and forms a lining for the carton. If the layflat tubing is impervious the method enables folding cartons to be manufactured in the form of a liquid-tight cup or similar container. |
