Definitions

  • the bread, biscuits, cookies, buns, rolls, etc. can be cooked directly in the paper board package in which they have been stored and displayed under conventional conditions e.g., 25 minutes at 350375F.
  • the storage, display and baking means are prepared in accordance with the invention by applying onto a sheet of cellulosic material, for example, a paperboard substrate, a coating composition consisting of a thickener or film forming material, a Werner type chromium complex and water, using conventional coating techniques.
  • the resultant product is then suitable for use both as the packaging means and as the cooking pan for the food.
  • the same coating can be applied onto paperboard where the resultant prodnets are intended for use asdisposable cooking trays.
  • the coating of the invention serves to impart two distinct unique qualities to the underlying cellulosic material and namely 1. grease resistance; and
  • the coating is readily applied by all of the known conventional methods. It is normally applied out of a water based system and, therefore, no expensive and often dangerous solvent recovery systems are required.
  • the coating composition in accordance with the invention comprises a thickener or film forming material such as polyvinyl alcohol, a Werner type chromium complex which is preferably a chrome-stearato complex, for example, Quilon (DuPont), and water.
  • a thickener or film forming material such as polyvinyl alcohol, a Werner type chromium complex which is preferably a chrome-stearato complex, for example, Quilon (DuPont), and water.
  • the components can be readily mixed in proper proportions for obtaining the results above mentioned.
  • the chrome complex In order to achieve the desired food release function of the coating, the chrome complex must constitute at least about 2 percent by weight of the coating formulation. A coating viscosity of no less than about cps., measured in Brookfield units at 72F. at 10 rpm, must be maintained to give proper coating spread.
  • a conventional thickener or film former such as polyvinyl alcohol, carboxymethyl-cellulose, sodium alginate, starches and the like, may be included in the formulation.
  • Such a thickener or film former as polyvinyl alcohol serves the additional function of imparting additional grease resistance to the coating.
  • the cellulosic substrate not be so porous as to be over-absorbent.
  • Such an overabsorbent substrate will allow excessive drainage of the food release coating, whereupon insufficient coating will remain on the surface to provide proper release. Accordingly, a minimum Cobb Size Specification of about 0.30 g. water absorbed must be maintained. This may be done by any of the known methods in the art, such as application of size either added in the furnish or onto the surface, application of a base coat, glazing, supercalendering, or similar finishing operations.
  • surfaces non-wettable by water such as attained by treating with materials such as wax, untreated polyolefins or water repellent chemicals, which cannot be coated with formulations of the invention by normal coating methods, are to be avoided.
  • Conventional coating or sizing application can be carried out before the application of coating of the invention by conventional procedures, such as application of two coats in one pass, or pre-sizing and coating in one pass, or beater sizing and coating on a paper machine, or the like.
  • Coated paperboard having grease resistant and non-sticking properties comprising a sheet of paperboard having a minimum Cobb Size Specification of about 0.30 g. water absorbed coated with a mixture consisting essentially of polyvinyl alcohol thickener and a sufficient proportion of Werner type chromium complex to impart said properties to the coated paperboard.
