US 2004/0166344 A1 · Self-closing packaging material

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.

Dependent claims

A package-forming material for forming a package which encloses and seals an article therein, comprising:

a packaging material in the form of a laminate comprising a first paper layer and a water impermeable plastic film that has at least one surface treated to increase its dynes and render it receptive to adhesives, wherein the film is laminated to the first paper sheet by a water-based adhesive that contacts the treated surface of the film and has its water absorbed by the paper sheet to effect lamination thereof, and wherein the film and paper layer have the same dimensions, and the laminate has a surface that is receptive to receiving adhesive or cohesive materials;
and
a cohesive material applied to one entire surface of the laminate;
wherein the packaging material is 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.

A process for creating a package which encloses and seals an article therein, which comprises:

providing a packaging material in the form of a laminate a laminate comprising a first paper layer and a water impermeable plastic film that has at least one surface treated to increase its dynes and render it receptive to adhesives, wherein the film is laminated to the first paper sheet by a water-based adhesive that contacts the treated surface of the film and has its water absorbed by the paper sheet to effect lamination thereof, and wherein the film and paper layer have the same dimensions, and the laminate has a surface that is receptive to receiving adhesive or cohesive materials;
applying a cohesive material to one entire laminate;
and
forming a package by placing the packaging material 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.
