Polymer reinforced composite plywood and laminates
Various examples are provided for polymer reinforced composite plywood and laminates. In one example, among others, polymer reinforced composite plywood includes a multilayer polymeric film bonded to a first ply of wood veneer and a second ply of wood veneer. A second multilayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, polymer reinforced composite plywood includes a monolayer polymeric film bonded to a first ply of wood veneer and to a second ply of wood veneer. A second monolayer polymeric film can be bonded to the second ply of wood veneer and to a third ply of wood veneer. In another example, low pressure laminate includes a polymeric film layer bonded to a base layer that forms a protective lamination layer over the base layer.
1. A polymeric-based low pressure laminate, comprising
a rigid base layer comprising medium density fiberboard (MDF), chipboard or plywood; and
a polymeric film layer comprising a first side and a second side opposite the first side, the second side having a printed wood grain type motif, pattern, or color, where the polymeric film layer is bonded to the rigid base layer under low pressure in a range from 10 bars to 30 bars (145-435 PSI) thereby forming a protective lamination layer over the rigid base layer that provides a high degree of resistance to impact, water, chemicals, and abrasion and scratch resistance of the low pressure laminate.
2. The polymeric-based low pressure laminate of claim 1 , wherein the first side of the polymeric film layer is bonded to a first side of the rigid base layer, and the second side of the polymeric film layer is over coated with a protective resin coating thereby protecting the printed wood grain type motif, pattern, or color.
3. The polymeric-based low pressure laminate of claim 2 , wherein the protective resin coating comprises melamine formaldehyde resin, urea formaldehyde resin, phenol formaldehyde resin or polyester resin.
4. The polymeric-based low pressure laminate of claim 2 , wherein the protective resin coating comprises a radiation curable resin.
5. The polymeric-based low pressure laminate of claim 1 , wherein the second side of the polymeric film layer having the printed wood grain type motif, pattern, or color is bonded to a first side of the rigid base layer under the low pressure in the range from 10 bars to 30 bars (145-435 PSI).
6. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer comprises a multilayer polymeric polyester film.
7. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer is bonded to the rigid base layer by a thermosetting polymeric adhesive comprising melamine formaldehyde resin, urea formaldehyde resin, phenol formaldehyde resin, acrylic resin, polyester resin, or polyurethane resin.
8. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer is bonded to the rigid base layer by a radiation curable adhesive.
9. The polymeric-based low pressure laminate of claim 2 , wherein the protective resin coating comprises acrylic resin or polyurethane resin.
10. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer comprises a monolayer polymeric polyester film.
11. The polymeric-based low pressure laminate of claim 2 , wherein the protective resin coating comprises a heat activated resin.
12. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer is bonded to the rigid base layer by a heat activated adhesive.
13. The polymeric-based low pressure laminate of claim 1 , wherein the rigid base layer comprises medium density fiberboard (MDF), chipboard, or plywood.
14. The polymeric-based low pressure laminate of claim 1 , wherein the polymeric film layer is opaque.
15. The polymeric-based low pressure laminate of claim 1 , wherein the second side comprises a printable surface having the printed wood grain type motif, pattern, or color thereon.
16. The polymeric-based low pressure laminate of claim 15 , wherein the printable surface is manufactured inline.
