摘要： A method of manufacturing a bag (1) with at least one window is provided. The method comprises the steps of firstly providing at least one window (8) in a sheet (2) of a first material. Secondly a second material is laminated to at least one surface of the sheet (2) of the first material such that the second material seals around the edges of the or each window (8). Lastly a bag (1) is formed from the laminated, windowed sheet of material such that one or more of the inner and/or outer surfaces of the bag (1) has the second material laminated thereto. The first material preferably comprises paper while the second material preferably comprises a plastics material. The lamination may be achieved by means of an adhesive or by heat-welding.
