An envelope has an envelope body formed by opposing panels that define an interior and an opening. A closure is joined to and extends up from the top margin of one panel. The envelope is configured such that the interior surface of the closure is sealable to the other panel to permanently close the envelope opening. The closure includes a closure panel and a tear band coextruded with the closure panel. The tear band is composed of a polymeric material having lower tear strength than the material of the closure panel. The tear band defines a zone of weakness extending along the width of the closure for opening the closure by tearing along the zone of weakness after it is permanently closed.

A reusable mailer convertible into a backpack includes a carrying volume defining a top opening configured to receive a package therein. A storage compartment is defined in the carrying volume and receives a secondary item. A drawstring is configured to close the top opening when cinched. Protective tape includes a first portion configured to removably adhere to a rear portion of the carrying volume and a second portion configured to extend across the top opening and removably adhere to a front portion of the carrying volume to configure the carrying volume for mailing. The protective tape, after mailing, is removed and the drawstring is uncinched to expose the package within the carrying volume and the secondary item in the storage compartment to a mail recipient. Opposite ends of the drawstring are reorientable into loops defined on opposing sides of the carrying volume thereby transforming the carrying volume into a backpack.

A reusable mailer includes a carrying volume having a top opening configured to receive a package therein, the carrying volume defined by an outer and inner peripheral surfaces, the inner peripheral surface covered by a plush material. Protective tape having a first portion is configured to removably adhere to a rear portion of the outer surface and is configured to extend across the top opening and a second portion is configured to removably adhere to a front portion of the outer surface to close the carrying volume and configure the carrying volume for mailing purposes. After mailing, the protective tape is selectively removable from the front and rear surfaces to expose the package. Once the package is removed from the carrying volume, the carrying volume is selectively inverted to transition and expose the plush material on the inner peripheral surface.

Automation-compatible reusable envelopes are embedded in standard envelope layouts, having a top flap outgoing envelope and an opposing bottom return seal flap. The return flap is formed by a person removing a unique flared tear strip that removes undesirable outgoing postal codes, and also forms a tapered return seal flap. The unique flare at each end of the tear strip is formed with lines of weakness that primarily extend parallel to the long bottom edge of the envelope, but that also wrap from the face across the bottom edge and then to the side edge of the envelope. A security tab and/or bridge structure is formed by removing a tear strip on the envelope, allowing access into the envelope.

The sealing device for a paper-based container has an elongated release base member with a double-sided adhesive layer on a major side along the length of the release base member. The release base member is adhered to a front portion of a flap of the container by the double-sided adhesive layer so that the flap may be used to seal the container. To open the container, a pull strip of the release base member is pulled off and the flap is separated. To reuse the container, a second sealing device is applied to another flap of the container so that the container may be reused.

An envelope formed from a sheet of flexible material and including: a lower section, an upper section superposed on the lower section, the sections being joined together by lateral edges, leaving an opening between the lateral edges, a protective strip on a layer of closing adhesive, the layer of closing adhesive being intended to ring about the closure of the envelope after the protective strip has been removed, and at least one precut region that is able to be detached from the envelope, the protective strip and the layer of closure adhesive extending at least partially over the precut region.
