Abstract
A machine is provided for creating perforated corrugated board, wherein the machine includes: a) at least one apparatus configured to perforate an “ACP” corrugated board after a corrugated board exits the corrugators as part of a continuous process, so that the perforations are spread over at least a portion of the corrugated board.
Claims15
A corrugated board which includes:
- a sheet of corrugated material;
- and
- at least one planar sheet of material bonded to at least one surface of said sheet of corrugated material;
- wherein said corrugated sheet and planar sheet(s) include a plurality of perforations spread over at least a portion of the respective surfaces thereof which are substantially aligned to create passages through the corrugated board, wherein the perforations are dimensioned to be substantially 0.5 mm2-2.00 mm2 in size and spaced at least substantially 4 mm-10 mm apart from one another.
A method of manufacturing perforated corrugated board characterised by the step of:
- a) forming perforations through the corrugated board once the corrugated board has been formed by bonding liner sheet(s) to a corrugated core as part of a continuous process wherein said perforations are spread over at least a portion of the corrugated board.
A machine for creating perforated corrugated board wherein the machine includes:
- a) at least one apparatus configured to perforate (hereafter referred to as an “ACP”) corrugated board after a corrugated board exits the corrugator as part of a continuous process, so that the perforations are spread over at least a portion of the corrugated board.
A closed cell coreboard which includes a plurality of substantially aligned perforations on each planar facing sheet positioned/spaced to create passages extending through the coreboard
A machine for creating semi-perforated corrugated board wherein the machine includes:
- at least one apparatus configured to perforate (hereafter referred to as an “ACP”) single face corrugated board after a corrugated board exits the corrugator as part of a continuous process;
- at least one double facing apparatus to laminate a non-perforated liner sheet to the perforated single face corrugated board.
A semi-perforated corrugated board which comprises:
- a perforated single face layer;
- and
- a non-perforated liner sheet layer.
A box or bin which has been manufactured from semi-perforated corrugated board.
