ABSTRACT:
Recyclable containers such as corrugated or folding boxes are made from a coated paper or kraft grade sheet including a plastic coating thereon. Aqueous acrylic resin containing compositions can be applied in excess on the paper or kraft grade sheet and the unwanted coating metered and removed by directing a jet of air at the coating. After solidification of the coating, the coated paper or kraft sheets can be incorporated as components of corrugated or folding boxes. Recovery of the unwanted coating permits recycling of the coating component. Corrugated and folding boxes including the components can be recycled by conventional repulping processes. A process of manufacture of the coated sheets is also disclosed.
