Paper and plastics bags (1) are used for packaging many diverse products such as food powders and granules, bread, rice, sugar, ground coffee, dried fruit, soap and detergent powders, and breakfast cereals. Such a reclosable paper or plastics bag (1) includes towards its closed end (2) a strip of elastic (4) fixed to the bag only at its ends. The elastics strip (4) has a length and an extensibility sufficient to enable it to be stretched to make a turn around the longest dimension of the bag (1) when filled. Preferably the present invention is used by rolling up or folding over the top (5) of a filled bag (1) after part of the contents have been used and then pulling the elastics strip (4) away from the bag and looping it around at least part of the longest dimension of the bag (1) to hold the rolled over top (5) closed. |
