摘要:
A treated paper product is provided according to the invention. The treated paper product comprises a result of applying a water based emulsion to a paper base sheet to provide an impregnated paper product, and drying the impregnated paper product to a water content of less than about 8 wt. % to provide the treated paper product. The water based emulsion includes a barrier and/or release forming component comprising at least one of stearylated melamine, polyethylene wax, paraffin wax, isoparaffin wax, microcrystalline wax, fluoropolymer wax, silicone wax, alkyl ketene materials, octyl succinic anhydride, Werner chrome complex, natural wax, and mixtures thereof. The water based emulsion can have a solids content of between about 2 wt. % and about 50 wt. % when it is applied to the paper base sheet. Methods for manufacturing and using the treated paper product, and a combination food and treated paper product are provided.
摘要:
A container seal having a releasable, integral promotional token attached thereto comprises a sealing sheet bound to a promotional token by a releasable adhesive. The sealant sheet has a tacking surface and a sealing surface. The promotional token has a tacking surface and an obverse surface. At least one surface of the promotional token has promotional indicia visible thereon. The tacking surface of the promotional token is bound to the tacking surface of the sealant sheet by a releasable adhesive, so that the promotional token is peelably removable from the sealant sheet when the sealant sheet is bound to the finish of a container. The promotional token consists of a material selected from the group consisting of a layer of paper or synthetic fabric, a layer of paper or synthetic fabric laminated to a polymer film, and a layer of paper or synthetic fabric laminated to two polymer films, and optionally, the tacking surface of the promotional token or the tacking surface of the sealant sheet comprises a release coating.

摘要:
Herein disclosed is a composition containing from about 5 weight parts to about 50 weight parts of a branched polylactic acid; from about 50 weight parts to about 95 weight parts of water; and from about 0.1 weight parts to about 1 weight part of a first surfactant. The composition can be coated onto a substrate containing paper or paperboard and having a first surface and a second surface, to form a paper product having oil, grease, and moisture resistance.
摘要:
A composition suitable for coating a paper product can comprise starch and at least one additional component selected from the group consisting of (a) an amphiphilic surfactant and (b) a particulate emulsion; wherein the weight ratio of surfactant to starch is from about 0.005:1 to about 0.25:1 and the weight ratio of the particulate emulsion to starch is from about 0.005:1 to about 0.429:1.
