    摘要: The invention relates to a preparation of high strength paper by incorporating a polymeric film into the paper web during the paper making process. The polymeric film is either a cold water soluble film or hot water soluble film or water insoluble hydrophilic film or non soluble non hydrophilic film or a combination of Cold + Hot + Cold water soluble film or Cold + Hot water soluble film or cold + non soluble hydrophilic film or cold + non soluble hydrophilic film + cold water soluble film or cold + non soluble non hydrophilic film or cold + non soluble non hydrophilic film + cold water soluble film or slit strips of one or many of these combinations woven or intertwined offline and incorporated into the paper during the paper making process. The invention also relates to zone coating or discreet printing or zone extrusion striping or formation of hot water soluble film on preformed cold water soluble film which is then inserted into paper during the paper making process, thus using cold water soluble film as a carrier. The said combination of the water soluble film(s) may be plain or wholly or partially perforated.
