Abstract
The present disclosure relates to a plastic laminate for covering agricultural crops. The plastic laminate includes an upper film having a plurality of upper film holes, and a bottom film having a plurality of bottom film holes. In use, the plastic laminate is arranged over a tunnel frame to form a greenhouse. The bottom film holes are arranged higher than neighbouring upper film holes. The present disclosure also relates to greenhouses that are made from such plastic laminates and also methods for manufacturing plastic laminates for covering agricultural crops.
Claims16
A plastic laminate configured for being arranged over a tunnel frame to cover agricultural crops, the tunnel frame having a top area extending along a longitudinal direction, and the plastic laminate comprising:
- an upper film comprising upper film holes;
- and
- a bottom film comprising bottom film holes, the upper film being attached to the bottom film,
- the plastic laminate having a central longitudinal axis configured to be arranged along the top area of the tunnel frame,
- the upper film holes being arranged on first and second sides of the central longitudinal axis, and the bottom film holes also being arranged on the first and second sides of the central longitudinal axis, and
- the upper film holes and bottom film holes being arranged such that when the plastic laminate is arranged over the tunnel frame, the bottom film holes are located at a vertically higher position than their respective neighbouring upper film holes.
A greenhouse comprising a tunnel frame having a top area extending along a longitudinal direction, and a plastic laminate configured for being arranged over the tunnel frame to cover agricultural crops, and wherein the plastic laminate comprises:
- an upper film comprising upper film holes;
- and
- a bottom film comprising bottom film holes, the upper film being attached to the bottom film,
- a central longitudinal axis configured to be arranged along the top area of the tunnel frame, wherein
- the upper film holes are arranged on first and second sides of the central longitudinal axis, and the bottom film holes are also arranged on the first and second sides of the central longitudinal axis,
- and wherein the upper film holes and the bottom film holes are arranged such that the bottom film holes are located at a vertically higher position than their respective neighbouring upper film holes.
A method for manufacturing a plastic laminate for being arranged over a tunnel frame to cover agricultural crops, the method comprising:
- providing an upper plastic film comprising upper film holes;
- providing a bottom plastic film comprising bottom film holes;
- joining the upper and bottom plastic films to form the plastic laminate, wherein the plastic laminate has a central longitudinal axis, and
- wherein the upper and bottom plastic films are joined such that the bottom film holes are closer to the central longitudinal axis than their respective neighbouring upper film holes, and wherein
- the upper plastic film comprises one or more longitudinal rows of upper film holes at a first side of the central longitudinal axis and one or more longitudinal rows of upper film holes at a second side of the central longitudinal axis, and wherein
- the bottom plastic film comprises one or more longitudinal rows of bottom film holes at the first side of the central longitudinal axis and one or more longitudinal rows of bottom film holes at the second side of the central longitudinal axis, and wherein
- the one or more longitudinal rows of bottom film holes are arranged closer to the central longitudinal axis than the one or more longitudinal rows of upper film holes respectively.
