Laminated pulp disposable paint tray
View Patent ↗Recycled paper pulp is processed to form a rigid paint tray base. The paint tray base is then laminated with a film, which may be fully or partially recyclable and/or biodegradable. The film prevents saturation of the pulp from the paint's moisture, which would damage the integrity of the pulp. Once the painting is completed, the film may be separated from the pulp base. The pulp base may then be discarded with wastepaper or used for compost. The film may be recycled or disposed of with other non-biodegradable waste.
1. A tray for holding a liquid paint therein, the tray comprising:
a molded pulp portion with side walls and a bottom wall comprising at least partially recycled paper and water resistant ingredients, the water resistant ingredients including gum resin added to the recycled paper;
a poly film laminate portion comprising a poly film, the poly film having a melting temperature between 350 and 550° Celsius and capable of being stretched to between 300 and 500% of its original length;
wherein the molded pulp portion is between about 0.2 mm and 2 mm thick in planar areas and about twice that thickness in non-planar areas or curved regions; and
wherein the laminate is between about 0.02 and 0.2 mm thick and applied by heat press atop the molded pulp portion without glue between the molded pulp portion and the laminate.
2. The tray of claim 1 , wherein the poly film comprises a material selected from the group consisting of polyethylene teraphthalate, polypropylene, polyethylene, or nylon.
3. The tray of claim 1 , wherein the laminate is applied by the heated press at a temperature between 150 and 250° Celsius for a time of 10 to 60 seconds.
4. The tray of claim 1 , wherein the poly film laminate is at least partially recyclable, at least partially degradable, and constructed of at least 50% recycled raw material.
5. The tray of claim 1 , wherein the laminate is easily removable from the molded pulp portion by a user without the aid of tools.
6. An environmentally-advantageous tray for holding liquid paint comprising:
a pulp tray constructed of recycled molded pulp of between 1 and 2 mm thickness and comprising a first upper side and a second lower side, the pulp comprising post-consumer waste paper and between 1 and 10% water-resistant chemical agent, the tray molded into a configuration selected from the group consisting of a nine-inch roller tray with dimensions 27×32×42 cm, a trim tray with dimensions 8.3×8.5 in., a paint edger, a drop catcher of dimensions 8.5×8.0 in., a mini-roller tray, a 6-inch roller tray with dimensions 12.0×10.5 in., a paint trim cup, and a disposable pour spout; and
a polylaminate film applied to the first side of the pulp tray, the film constructed of 100% post-consumer material selected from the group consisting of polyethylene teraphthalate, polypropylene, polyethylene, polylactic acid, low-density polyethylene, high-density polyethylene, and nylon; the film being between 0.02 and 0.2 mm thick.
