A bag, package or envelope suitable for being mailed or posted comprises two sealing strips 4, 5, which are covered by protective strips before use. The strips are attached to the bag using a flap 7 at the top of the bag. The double sealing strip permits the bag to be resealed after one use, which in turn allows the convenient return of the package. The bottom of the bag does not open and might comprise folded polythene 2. The bag might be used in a click and collect purchase system. The bag may comprise a punched-out handle (POH). |
