Abstract
An extruded plastic lattice sheet, and method of making the same, the plastic lattice including a perforated sheet of plastic resin formed from an extruded sheet of plastic resin having been die punched to remove portions of plastic resin leaving a crisscross pattern. The outer surface of the perforated sheet is embossed with a wood grain effect and has a substantially three-dimensional-like appearance of slats formed by an embossing step. Both single-layer and multi-layer lattice sheet is disclosed.
Claims18
An extruded plastic lattice sheet comprising:
- a perforated sheet of plastic resin formed from an extruded sheet of plastic resin having been die punched to remove portions of plastic resin leaving a crisscross pattern;
- and
- wherein an outer surface of the perforated sheet is embossed with a wood grain effect.
A method of manufacturing a plastic lattice component, the method comprising the steps of:
- extruding a sheet of plastic resin through a flat sheet die;
- cutting the sheet of plastic resin to a desired length;
- die punching the sheet of plastic resin to remove some portions of plastic resin, leaving a perforated sheet;
- and
- embossing the cut sheet of plastic resin to impart an appearance of criss-cross plastic slats and a wood grain surface.
A method of manufacturing a plastic sheet having a lattice-like appearance, the method comprising the steps of:
- extruding a sheet of plastic resin comprising a mixture of prime high-density polyethylene resin, recycled high-density polyethylene resin, and an additive through a flat sheet die;
- cutting the plastic resin to a desired length;
- die punching the sheet of plastic resin to remove diamond-shaped pieces of plastic resin;
- and
- embossing the cut sheet of plastic resin to impart an appearance of raised plastic slats having a wood grain-like pattern thereon.
