发明名称 METHOD FOR PRODUCING A BAG-LIKE STORAGE CONTAINER FOR CUT FLOWERS
摘要 A method for producing a bag-like storage container for cut flowers comprising a flexible cover of a water-impermeable thermoplastic film and an inner coating of an absorbent material is described. The absorbent material thereby forms a soakable water reservoir for the cut flowers. The absorbent material is covered by a water-permeable cover layer of thermoplastic plastic, wherein the water-impermeable thermoplastic film is folded over the inner coating of soakable material towards the inside in the area of a bag opening and is connected to the cover layer at least on one side in the fold-over area. The method includes a method step, in the case of which a welding is carried out along longitudinal edges (6a, b) such that two layers of the water-permeable cover layer are located between two layers of the water-impermeable film in the area of welding seams (7).
