Abstract: A non-odorous 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. Preferably, 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 non-odorous 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.

Abstract: A paper-plastic laminate sheeting capable of being converted by conventional equipment into envelopes, grocery bags and other dilatable container products that initially are in a flat state and are normally made of paper. The sheeting is composed of a paper facing sheet cold-laminated by means of a water-based adhesive to a reinforcing film of synthetic plastic material, such as polypropylene. The film is oriented to impart exceptional tear and burst strength characteristics to the resultant waterproof product. The product, whose exterior surface is formed by the paper facing sheet, is readily printable. For some applications, a second paper facing sheet is cold-laminated to the other side of the film to produce a three-ply laminate sheeting whose exposed surfaces are readily printable and can accept conventional adhesives.

Abstract: The present invention relates to a new packaging material in the form of a unitary laminate sheeting. The package-forming material comprises a unitary sheeting of a first paper layer laminated to a water-impermeable plastic film for forming a package which encloses and seals an article therein. The film and paper layer advantageously have the same dimensions, and the laminate has a surface that is receptive to receiving adhesive or cohesive materials. A coating of cohesive material covers at least a portion of one of the first and second outer surfaces, and the packaging material can be placed about an article to be packaged such that a first portion of the surface of the packaging material that includes cohesive material contacts another portion of the surface that includes cohesive material to adhere such portions to each other and form a sealed package which encloses the article. Also, the adhered cohesive portions can form an adhered band which completely surrounds the article to be packaged.

Abstract: A self-closing resealable packaging material formed from at least one sheet of a package forming material, which encloses and seals and article therein. A cohesive material is applied to surface portions of the packaging material so that when wrapped around an article cohesive portions stick together and seal the package. To make the package resealable a liner is placed upon at least a part of the cohesive material containing surface so that a non-adhering margin is formed and the unused cohesive can be utilized reseal the package after its initial opening.

Abstract: A process for making a resealable package that that is formed from a packaging material, which is coated with cohesive material with a liner covering a portion of the cohesive material such that when the laminate is folded about an article to be enclosed the liner inhibits some of the cohesive from sticking to itself. The packaging material may further include a strip of pressure sensitive adhesive for resealing the package.
