Abstract:
A food-safe composition and resulting article with grease and water resistance properties comprised of a petroleum wax based aqueous emulsion, a food-safe coating formulation, and an alkyl ketene dimer (AKD), wherein the composition exhibits grease and water resistant properties without a fluorinated compound present in the composition. A method of making the composition and a method of using the composition to form pulp molded articles such as food-safe containers and other pulp-based food packaging and utensils are provided.
Abstract:
Composite boards are disclosed herein. An example of the composite board includes a first outer layer, a second outer layer, and a middle layer positioned between the first and second outer layers. The first and second outer layers each include chemical pulped cellulose fibers and low moisture absorbing fibers. The middle layer includes the cellulose fibers and a moisture repelling agent. Also disclosed herein are art frames that include the composite boards.

Abstract:
Waxes prepared from hydrogenated plant oils, such as castor and soybean, are formulated into aqueous ink and paper coating compositions. Ink compositions comprising these waxes and evaluated for their resistance to mar and abrasion achieved rub resistance and slip performance comparable to compositions utilizing conventional wax additives, which are generally derived from petroleum. The waxes in the inventive compositions have a low iodine value (ranging from approximately 2 to approximately 5), and a melting point between approximately 120 degrees to approximately 190 degrees F. (Mettler Drop Point). These naturally derived waxes are used as an alternative to petroleum and synthetically derived waxes in the manufacture of inks and coatings for paper and cellulosic products.
Abstract:
Some embodiments of the invention generally relate to a moisture barrier coating that is biodegradable and compostable. Some embodiments also relate to a coating that is dual ovenable. Such coatings may be used to increase moisture resistance and provide non-stick or release characteristics when applied to biodegradable and compostable disposable food packaging and food service items. In some embodiments, a plasticizer, an amide wax and optionally a rosin are added to a cellulose-ester-based coating to increase moisture resistance. In other embodiments, a biodegradable polymer, an amide wax, optionally a plasticizer, and optionally a rosin are added to a cellulose-ester-based coating to drastically increase moisture resistance. In still other embodiments, phospholipids or medium-chain triglycerides or increased levels of amide wax may be added to the either of the embodiments above to provide enhanced release characteristics.
Abstract:
The present invention relates to a wetting solution for manufacturing wet wipes or other wet flexible materials, and to such wet wipes for cosmetic, body care, dermatological and/or cleaning purposes, such as cleaning wipes, facial cleaning wipes, make-up remover wipes, refreshment wipes, baby wipes, wet toilet paper or eyeglass cleaning wipes, wherein the preferably aqueous wetting solution contains at least one amino acid ester, preferably from the group of pyrrolidone carboxylic acid esters, as an emulsifier. The invention further relates to the use of such amino acid esters as emulsifiers in wetting solutions for manufacturing said wet tissues.

Abstract:
A formulation, and a process for making same, is disclosed which is useful as a coating or treatment for imparting oil and grease resistance to an underlying substrate. The formulation does not contain any fluorochemicals. At the same time, however, the formulation provides oil and grease resistance properties that are equivalent to known coatings and treatments which contain fluorochemicals, particularly those coatings which are permitted to come into direct contact with food products. Therefore, the formulation of the present invention is ideal for use as a coating for paper and paperboard, including paper packaging such as that utilized in food wrappers, food containers, food receptacles and the like, and for other shaped articles. The formulation is also useful as a coating or treatment for providing release properties to an underlying substrate without the use of silicone. In addition, the present invention relates to the process for making the underlying substrate ideal for holdout of the release coating without excessive fiber refining, as in glassine papers. The formulation is a low solids coating that can be applied on the size press of a paper machine, eliminating the need for a post-machine coating process. The formulation does not include silicone, thereby allowing the release paper to be re-pulped. The wet end additive that provides sheet holdout combines with the release formulation to provide a release paper for pressure sensitive adhesives.
