Abstract
The invention refers to a sheet for greenhouses produced by ejection process from a circular matrix, which sheet during its production is creased in order to become flat. Afterwards, it is cut along the creases. The ends of the two formed plastic sheets are folded over in order to form two narrow folded-over straps of 5 to 20 cm in width and preferably 10 cm. One of these straps is thermally stitched so that a long, narrow, and proof chamber is formed.
