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 plastic-paper-plastic laminate sheeting whose plies have different properties that depend on package requirements, with the outer and inner plies in the laminate being oriented, synthetic plastic films of high tensile strength. The plies are adhesively interlaminated to an inner ply of paper 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 laminate may also be made into a water-resistant envelope or package for mailing various materials.

Abstract: A self-closing package formed from a unitary two-ply or three-ply laminate sheeting having an inner surface which is entirely coated with cohesive material, which has the property of sticking only to itself, and having a first portion and second portion. An article may be placed on the first portion of the laminate sheeting before folding and forming he laminate sheeting into a self-closing package. To form the package, the second portion of the laminate sheeting is pulled upward around the article and folded over both the article and the first portion of the laminate sheeting so that the inner surface of both the first portion and second portion are opposed to each other. The package is closed and sealed by the cohesive coated inner surfaces of the first and second portions coming into contact with each other and thereby sticking to each other.

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.

Abstract: 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 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 interlaminated 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 laminate may also be made into a water-resistant envelope or package for mailing various materials.

Abstract: A pressure-sensitive laminate for adhering to various items. The laminate includes a paper layer; a water-impermeable plastic film layer having a first corona-discharge treated surface which is adhesively laminated to the paper layer to form a paper-plastic film laminate having first and second opposed outer surfaces; and an exposed layer of a pressure-sensitive adhesive coating on one of the first or second outer surfaces. The plastic film portion of the laminate has a strength sufficient to allow the film to be stripped in one piece from an item to which the laminate is adhered. The laminate may, if desired, additionally have a layer of a release agent upon an uncoated one of the first and second opposed outer surfaces of the laminate. A preferred use for the laminate is as a pressure-sensitive tape product.

Abstract: A pressure-sensitive sealing tape product for adhering to various items in applications involving taping and sealing, and having sufficient body to permit dispensing from a conventional pull and tear tape dispenser. The tape includes a paper layer; a water-impermeable plastic film layer having a first corona-discharge treated surface which is adhesively laminated to the paper layer to form a paper-plastic film laminate having first and second opposed outer surfaces; and an exposed layer of a pressure-sensitive adhesive coating on one of the first or second outer surfaces.

The tape product may, if desired, additionally comprise a layer of a release agent upon an uncoated one of the first and second opposed outer surfaces of the laminate.

Abstract: A heat-activated sealing tape for manufacturing or sealing a carton or other article. The tape is composed of a paper layer, a layer formed of oriented plastic film which is adhesively laminated to the paper layer, and a heat-activatable adhesive exposed for use in adhering the paper-plastic film laminate to an object. The heat activatable adhesive is inactive at ambient temperatures. When exposed to low temperature heat sealing conditions, the adhesive is activated and enables the tape to be adhered to the article to be sealed. The sealing tape is designed for ease of handling and reduction in waste, and is adaptable for use in existing automatic and semi-automatic equipment for manufacturing or sealing cartons.

Abstract: A container having walls made of a paper/plastic laminate having a cardboard core sandwiched between inner and outer face liners, wherein at least one of the face liners is comprised of a face liner laminate. The face liner laminate is composed of an exterior ply of oriented synthetic plastic film whose opposing surfaces are rendered wettable by corona-discharge treatment, and a base paper ply is cold-laminated to the film ply and adhered to the core of the board. The cardboard core may be a fluted medium of corrugated paper board, or it may be a planar stiff paper core. The invention is also directed to a structural member for use in making inexpensive furniture comprising a supporting member and a cardboard core laminated to a face liner laminate. The film ply of the laminate enhances the strength of the container or structural member and imparts water resistance thereto. Because the exposed surface of the film ply is printable, it may have decorative graphics or other printed matter applied thereto.
