A bag (40) has two opposite facing surfaces (45,48) defining a pre-formed opening (47) at least one of the surfaces (45, 48) having a re-usable pressure sensitive adhesive (49) thereon so that closure of the opening (47) is effected by pressing the said surfaces (45, 48) together in the area of the adhesive (49) thereby to provide a re-openable closure. |
