Definitions

  • the invention relates to the papermaking art and, in particular, to the manufacture of paper products having basis weights above about 80 pounds per 3000 square feet up to and including about 300 pounds per 3000 square feet, such as file folders, non- corrugated containers, and the like, which exhibit improved properties for office environments and long term storage.
  • Heavy weight cellulosic paper and paperboard products such as file folders and paperboard file containers are often subject to liquid or moisture damage during routine handling and long term storage.
  • such products if stored in a humid environment, tend to support biological growth which results in undesirable odors being produced.
  • the invention provides a method for increasing the long term storageability of a cellulosic paper or paperboard product.
  • the method includes providing a paper or paperboard product made from cellulosic fibers having a basis weight ranging from about 80 to about 300 pounds per 3000 square feet.
  • a holdout material is applied to at least one surface of the paper or paperboard product to provide a sized web of paper or paperboard.
  • the sized web is then coated with an ink receptive material selected from the group consisting of an aqueous acrylic polymer coating material, an aqueous biocidal agent and a combination of aqueous acrylic polymer coating material and aqueous biocidal agent to provide an ink receptive layer.
  • the web is dried at a first temperature to provide a coated web.
  • an uncoated side of the web is wetted with an aqueous fluid and dried at a second temperature to provide a paper or paperboard product having enhanced long term storageability.
  • the invention provides a method for reducing microbial growth on stored paper or paperboard products.
  • the method includes providing a paper or paperboard product made from cellulosic fibers having a basis weight ranging from about 80 to about 300 pounds per 3000 square feet. At least one surface of the paper or paperboard product is sized with from about 0.5 to about 1.5 percent by weight starch sizing agent to provide a sized web of paper or paperboard. The sized web is coated with an aqueous biocidal agent and the web is dried to provide a paper or paperboard product having reduced tendency for microbial growth.
  • the paper or paperboard composite includes a base layer formed from a cellulosic fiber substrate, the base layer having a first surface, second surface and a basis weight ranging from about 80 to about 300 pounds per 3000 square feet.
  • a holdout layer is applied adjacent the first surface of the base layer.
  • An ink receptive coating material is applied adj acent the holdout layer to provide an ink receptive layer.
  • the ink receptive coating material is selected from the group consisting of an aqueous acrylic polymer coating material, an aqueous biocidal agent and a combination of aqueous acrylic polymer coating material and aqueous biocidal agent.
  • An advantage of the invention is that relatively heavy weight paper and paperboard products may be stored for a long term without significant deterioration or production of odor causing organisms.
  • the products of the invention also exhibit improved long term durability and resist damage and staining caused by water and other aqueous fluids.
  • Another advantage of the invention is that paper and paperboard webs made according to the invention exhibit less tendency to slide relative to one another as compared thermoplastic coated webs which are difficult to stack on one another because of their slick surface.
  • Figs. 1 -3 are cross-sectional views not to scale of paper or paperboard products according to the invention.
  • Fig.4 is a schematic flow diagram, not to scale, of a process for making paper and paperboard products according to the invention.

  • a metal base plate with a clamping device is used to hold the ring against the sample of paper to be tested and a neoprene mat.
  • Neoprene gaskets may be used to seal the cylinder against the web when the test sample is uneven.
  • An important component of the test apparatus is a solid stainless steel roller having a smooth face about 20 cm wide and weighing about 10 kg. Also used for the test are a 100 mL graduated cylinder, a balance with sensitivity of 0.01 grams or better, blotting paper, and a timer or stopwatch.
  • a sample of paperboard material to be tested is cut approximately 12.5 x 12.5 cm square from the coated web.
  • the sample is weighed and placed on the neoprene mat.
  • the cylinder is clamped upon the sample by locking a crossbar in place and tightening two knobs. If sample material is textured, a gasket is placed between the sample and cylinder, carefully aligning the inner edges of each.
  • the test liquid in this case preferably water is poured into the test cylinder.
  • the amount of test liquid is preferably 100 mL for 100 square centimeter cylinder. Proportionately less liquid is used for smaller cylinders. After pouring the liquid, the timer is started to provide a five minute test. Longer and shorter test periods may be provided.
  • the liquid is quickly poured from the cylinder, using care in not dropping any liquid on the untreated (outside) portion of the test specimen.
  • the cylinder is removed from the sample and the sample is placed with wetted side up on a sheet of blotting paper.
  • a second sheet of blotting paper is placed on top of the sample to remove the surplus liquid by moving the hand roller once forward and once backward over the sample and blotting paper. Care should be taken not to exert downward force on the roller.
  • the specimen is then folded after removing it from between the blotter sheets and re-weighed to the nearest 0.01 gram. The initial weight of the web is subtracted from the final weight of the sample and the gain in weight in grams is multiplied by 100 for a 100 cm 2 cylinder to obtain the weight of liquid absorbed in grams per square meter.
  • the resistance of the coated web to staining is determined by pouring a small amount of aqueous liquid such as coffee, soda, juice onto the coated web. The aqueous fluid is then wiped off after 30 seconds and the web is visually examined for evidence of staining or warping. Webs produced according to the invention exhibited less staining with dark fluids and less warping than conventional webs.
  • the agent for reducing biological activity included in layer 14 is preferably a haloalkynyl carbamate.
  • a particularly preferred haloalkynyl alkyl carbamate is a halopropynyl carbamate, most preferably 3-iodo-2-propynyl butyl carbamate available as a latex dispersion wherein the active ingredient is present in the dispersion in an amount ranging from about 15 to about 30 percent by weight of the dispersion.
  • Particularly preferred biocidal agents include aqueous dispersions available from Buckman Laboratories of Memphis, Tennessee under the trade names BUSAN 1420, BUSAN 1440, and BUSAN 1192D.
