Abstract: Waterproofed paper and paperboard forms utensils, tools, and cutlery. The waterproofed paper is made by applying a waterproof composition to the paper and then cutting and molding the waterproofed paper to the shape of a utensil, tool, or piece of cutlery. Paper and paperboard that is particularly useful in forming strong utensils, tools, and cutlery that do not bend or snap during normal use.

Abstract: A composition that includes plant derived wax having a melting point of at least 70° C. can be used to waterproof cellulose based materials like paper and board. Suitable waxes include sugarcane wax and rice-bran wax. A surfactant such as stearic acid improves the adhesion of the composition to the underlying material. The resulting waterproof laminate can be economically recycled. Hot beverage cups made from the laminate are waterproof and recyclable without first being separated into components. Coffee pods and drinking straws that are waterproof and recyclable are manufactured with the waterproof laminate.
