The present invention relates to sheet-like materials suitable for use in the containment and
protection of various items, as well as the preservation of perishable materials such as food items.
More particularly, the present invention provides an improved storage wrap material comprising a
sheet of material having a first side and a second side. The first side comprises and active side
exhibiting an adhesion peel force after activation by a user which is greater than an adhesion peel
force exhibited prior to activation by a user. The storage wrap material may be activated by
different approaches, but in a preferred embodiment the active side is activatible by an externally
applied force exerted upon sheet of material. The force may be an externally applied compressive
forced exerted in a direction substantially normal to the sheet of material. In accordance with the
present invention, the storage wrap material is selectively activatible by a user in discrete regions
to provide adhesive properties where and when desired. The use of an adhesive or adhesive-like
substance on the surface of the material provides an adhesion peel force after activation, which is
sufficient to form a barrier seal against a target surface at least as great as those of the material and
the target surface such that perishable items, such as food items, may be effectively preserved. The
storage wrap materials of the present invention may be utilized to enclose and protect a wide
variety of items by various methods of application, including direct application to the desired item,
enclosure of the desired items and securement to itself, and /or in combination with a semienclosed
container.
