Abstract
The invention relates to an apertured camouflage material where the apertures are made as arcuate slits so that tongues are formed (FIGS. 4A, 4B). The material is a laminate of a supporting layer to which is applied a plastics layer which is initially under internal tensional stress, the tongues curling outwards when the internal stresses are activated by the slitting and heat (see FIG. 4B) thus forming a three-dimensional camouflage sheet. The pre-stressed material is blown low density polyethylene film.
