  • Patent number: 5932639
    Abstract: The present invention is directed to remoistenable and non-remoistenable adhesives which contain at least about 50 wt % of a maltodextrin syrup having a reducing sugar content of about 5-19 dextrose equivalent and solids content of about 60-80 % water, and an effective amount of other conventional adhesive additives. When the adhesive is a remoistenable adhesive, a chemically derivatized starch having an amylose content of 40 % or less and a D.S. of about 0.01 to less than about 0.50 is used. A preferred remoistenable adhesive also contains polyvinyl acetate and/or ethylene vinyl acetate in an amount from about 15-90 wt. % The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized or underivatized granular starch, by a high solids, single phase enzyme conversion process. When derivatized, the maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50.

  • Patent number: 5641349
    Abstract: Thermally-inhibited starches and flours are used in conventional water-based adhesives such as corrugating, cigarette, remoistenable, kraft adhesives. The starches or flours are thermally-inhibited by dehydrating the starch to anhydrous or substantially anhydrous and then heat-treating the starch or flour for a time and at a temperature sufficient to inhibit the starch and improve its viscosity stability. The starch or flour may be thermally or non-thermally dehydrated (e.g., by alcohol extraction or freeze-drying). Preferably, the pH of the starch is adjusted to at least a neutral pH prior to the dehydration.

  • Patent number: 5545472
    Abstract: A specific class of water-borne, water redispersible laminating adhesives is disclosed which is desirable for bonding nonwoven substrates to themselves or to other substrates. The adhesives provide improved bond strength and improved water redispersibility when compared to laminating adhesives currently used for the same purpose. Furthermore, the novel adhesives are much less sensitive to the presence of significant levels of plasticizer than are laminating adhesives currently used, which exhibit reduced water redispersibility when such plasticizers are present in significant amounts. The novel laminating adhesives contain an aqueous styrene/acrylic polymer dispersion prepared by radical-initiated emulsion polymerization of unsaturated monomers in the presence of starch degradation products having a weight average molecular weight range of from about 2500 to 25000 and which are obtainable by hydrolysis in the aqueous phase.

  • Patent number: 5519072
    Abstract: Adhesive compositions which are free of humectants are prepared from vinyl acetate homopolymer and/or ethylene vinyl acetate copolymer latices which have been prepared by emulsion polymerization methods which utilize dextrin as the protective colloid. The adhesives are characterized by superior adhesion in case making and are prepared by post-adding specific amounts dextrin and a borax to the dextrin-emulsified polymer latex.
