A biocide containing laminate for use in the construction of a wide variety of products. A preferred product is a pouch or other container for forming an envelope protectively packaging a product such as a flowable or solid food substance. The pouch is fabricated from a paper-plastic laminate sheeting whose plies have different properties that depend on package requirements, at least one ply in the laminate being an oriented, synthetic plastic film of high tensile strength. The plies are adhesively laminated at ambient temperature with a water-based adhesive whereby the orientation of the film is unaffected by the laminating process, in the course of which no environmentally objectionable fumes are discharged into the atmosphere. The biocide is associated with the paper material or water-based adhesive of the laminate in an amount sufficient to render it resistant to attack from organisms. The plastic film protects and retains the biocide in the laminate. The laminate may be made into an organism-resistant tape, a water-resistant envelope, or a package for mailing various materials. |
