Starch-based corrugating adhesive having cross-linked polyvinyl alcohol components

摘要: Corrugating adhesives and premixes containing polyvinyl alcohol reacted with ketone-aldehyde resins are provided which exhibit stable viscosities excellent adhesive properties. The premix formulations include PVA a selected resin, preferably in the absence of starch or borax, order to yield pourable compositions retain viscosity over extended storage periods at ambient temperature. can be added including starch, alkali borax give corrugating resist premature gelation have good wet tack
