Abstract: The present invention relates to a multi-layered composite bag used to store bulk type products such as pet food, seeds, fertilizer, cereals, grains, charcoal, sand, gravel, and other bulk products, including without limitation bulk products intended for human and non-human consumption, and provides a more efficient manufacturing process than using a paper/plastic structure. The present invention provides a bag comprising a middle layer of woven mesh tubing to which an outer layer of solid plastic film is adhered using polypropylene or other polylaminates.

Abstract: A method of making a bag, wherein a first layer of heat activated adhesive material is on a portion of the bag to form an adhesive-to-adhesive seal by contact with a second layer of heat activated adhesive material on a portion of the bag second panel, wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric bag material, and wherein sealing the bag end after the bag has been filled with contents by heat activating the first layer of adhesive material and the second layer of adhesive material at a temperature below the softening point temperature of the polymeric bag material.
