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.

Heat transfer label assembly

A heat transfer label assembly comprises a label and a carrier for releasably supporting the label. The carrier may comprise paper. A release layer comprising a polymer and wax is disposed between the label and the carrier. The carrier is substantially devoid of a solvent impermeable coating, such that the release layer is disposed directly on the paper.

Compostable Packaging Material
