Multi-layer plastic sheets, especially 3-layer, reflective sheets contg a metallic layer, are sealed along their edges to protect their physical properties (thickness, reflectiveness, resistance to ambient conditions). - The edges are prepd using the same material which forms pt of the sheet, such that two base layers (3) are located on top of each other. - These two layers are welded together at a temperature based on the melting point of the base material. The procedure is especially suitable for composite sheets of polyethylene base layer, aluminium centre layer and polypropylene top layer. In this case the welding temp will be based on the melting point of polyethylene
