Process for forming paper-based products having cement-based coatings.

摘要

A process for forming a moulded paper product which is degradable in a moisture active landfill is disclosed. The process involves providing a paper pulped paper feedstock, moulding the feedstock to produce a shaped product, drying the shaped product, applying a coating composition on to at least one surface of the shaped product, curing the coating composition and, optionally, hot pressing the resulting product to form a moulded paper product. When the moulded paper product is coated utilizing a particularly preferred coating composition described herein, which is comprised of a cement, at least one of a clay and a sulphate, an aqueous emulsion polymer, and preferably, at least one of an organic acid and a wax, it is readily degradable in a moisture active landfill. <IMAGE>
