Definitions

  • the present invention relates to a water-resistant adhesive composition which is especially suitable as an adhesive for corrugated boxboards.
  • the invention also relates to a process for preparing said composition and to an use of said composition as an adhesive for corrugated boxboards.
  • a gluing process is carried out and comprises the transfer of a glue line of a starch adhesive composition from an applicator roll to the flute tips of a corrugated medium, the application of a liner thereon and the heating of the adhesive composition to gelatinize the uncooked starch and form a bond between said tips and liner.
  • the amount of heat required to evaporate water contained in the glue and gelatinize the uncooked starch significantly increases when manufacturing double and triple wall boards, to thus negatively affect the speed of the process and the possibility of having a sufficient amount of heat through the whole boxboard.
  • SUBSTITUTE SHEET Also, it is to be noted that it is well known in the art to provide water resistance to boxboards when adding in the starch adhesive composition a resin such as ketone aldehyde, to cross-link the water-soluble starch. However, the pot life of such a mixture is limited to 6 to 8 hours. Also, the water resistance of said cross-linked starch is not sufficient for packaging containers used in transportation or storage of vegetable products, meat products or other moisture containing materials. Furthermore, it is to be noted that the current materials used to cross-link starch, such as borax, boric acid, ketones, aldehydes and formaldehyde, are toxic, and a move is underway to restrict their use in food packaging.
  • the present invention relates to a water-resistant adhesive composition, especially usable as an adhesive composition for the manufacturing of corrugated boxboards.
  • Said composition preferably offers a high degree of water resistance, and because faster bond development, allows substantial gains in production speed.
  • the invention relates to a novel adhesive composition of polymer/thickener/crosslinker which can be optionally combined with starch and/or water; the composition developing faster bond strength and having a significantly higher water resistance than standard starch adhesive compositions for corrugating boxboards, and the optional uncooked starch content helping to reduce the overall cost.
  • the invention advantageously relates to a water-resistant adhesive composition for corrugated boxboards that is free of conventional materials intended to cross-link starch, such as borax, formaldehyde resins, etc.
  • constituents of the adhesive composition may be considered acceptable by the FDA (Federal Drug Adminstration of the U.S.A.) .
  • the present invention advantageously relates to a water- resistant adhesive composition allowing boxmakers to manufacture products that are less toxic and environmentally safe.
  • the invention relates to a novel adhesive composition which develops high enough bond strength and water resistance to avoid the use of wax coatings especially on the fluted medium in produce packaging.
  • This characteristic allows substantial savings in materials and better repulpability of the boxboards defining said packaging.
  • Said composition is much more environmentally safe than current starch adhesive compositions for corrugating boxboards since boxboards obtained are free of toxic substances such as wax, borax, boric acid and aldehyde resins.
  • the present invention advantageously relates to a water- resistant adhesive composition usable with high speed corrugators devices and/or corrugator devices running heavyweight boards and requiring a short tack time.
  • tack time may be also referred to as being the time between the gel point and a substantial set-back of the starch. Such a time needs to be reduced in order to achieve good adhesion before the board reaches the slitter scorer, in order to avoid the presence of loose edges.
  • a short tack time involves an increased producibility.
  • the invention relates to an adhesive composition which unlike cooked starch adhesive compositions, can be used as such or with an optional addition of raw starch (for cost reduction), to thus allow since cooking is unnecessary, a considerable saving in time and energy and a significant improvement in pot life (i.e. substantially extended pot- life).
  • the pot life of a wet and non cross-linked adhesive composition according to the invention may be of about 6 months when it does not contain any starch and of about 3 - 4 days when it contains uncooked or raw starch. Furthermore, the pot life of a wet and non cross-linked adhesive composition containing uncooked or raw starch may be extended by the addition of at least one biocide therein.
  • the invention relates to an adhesive composition having an improved bond development, the edge profile at a slitter and/or die cutter being considerably improved; said composition providing the necessary bond and stiffness to allow clean, undelaminatable or crushed edges, without developing "brittleness".
  • the invention relates to a novel adhesive composition having a high solids content (for example from 40% to 50% w/w of solids and preferably of about 47% w/w of solids) which permits greater production speeds (some more than 100% increase) without delamination; this being particularly significant in triple wall structure.
  • a high solids content for example from 40% to 50% w/w of solids and preferably of about 47% w/w of solids
  • the invention advantageously relates to a water-resistant adhesive composition allowing to replace usual starch adhesive compositions (i.e. glue) while having nearly identical viscoelasticity for simplified runnability on current machinery.
  • the invention advantageously relates to a water-resistant adhesive composition which, for safety reason (e.g. fire) is based on an aqueous polymer for compatibility with current starch and has a pH > 6, to allow cost reduction.
  • the invention relates to a water-resistant adhesive composition characterized in that is comprises: an aqueous polymer dispersion defining a binder, said polymer having functional groups to allow cross linking mechanism (e.g. carboxyl group);
  • cross-linker capable of non-thermal reaction with said binder and thickener at a pH value greater or equal to
