Abstract

A bag having a reclosable sealer and methods of forming and using the same are provided. The bag, for example, can include a tube body having a plurality of laminated layers. A reclosable sealer can be attached to a first wall of the tube body. When the bag is in an open bag position, a first portion of the reclosable sealer is separated from a second portion of the reclosable sealer. When the reclosable sealer is in the closed seal position, the first portion of the reclosable sealer contacts the second portion of the reclosable sealer forming a seal to thereby allow the bag to be readily opened and closed. Peripheral portions of the bag can remain unsealed after initial opening when the reclosable sealer is in the closed seal position to indicate that initial opening has occurred and that tampering with the bag may have occurred.

Claims

1. A method of forming a bag having a reclosable sealer associated therewith, the method comprising:

providing a laminated material comprising at least one of a polymeric material, a metal foil material, and a paper material;

forming a tube body from the laminated material, wherein the laminated material defines an inner surface of the tube body and an outer surface of the tube body and the tube body includes an open end, a closed end, a first wall extending between the open end and the closed end, and a second wall extending between the open end and the closed end and being positioned to face opposite the first wall;

providing a reclosable sealer comprising;

a first portion including a first adhesive layer positioned to adhere the first portion of the reclosable sealer to an outer surface of the tube body, a first film layer overlying and in contact with the first adhesive layer, and a second adhesive layer overlying and in contact with the first film layer; and

a second portion including a second film layer in abutting contact with the second adhesive layer of the first portion and a paper layer overlying and in contact with the second film layer;

attaching the reclosable sealer to the tube body on an outer surface of the first wall adjacent the open end, the reclosable sealer being attached to the outer surface of the first wall such that the first adhesive layer of the first portion of the reclosable sealer bonds the reclosable sealer to the outer surface of the first wall and the paper layer of the second portion of the reclosable sealer creates an outwardly facing surface;

positioning a bonding material on the outwardly facing surface of the second portion of the reclosable sealer; and

positioning a protective disposable layer over the bonding material thereby protecting the bonding material until the open end of the tube body is closed and an outer surface of the second wall of the tube body is brought into contact with the bonding material to close the bag.
