<p>FIELD: packing and packing materials. SUBSTANCE: packing laminate has layer of silicon oxide which serves as gas-tight layer, and layer of metal serves and light-tight layer. These layers are applied by vacuum precipitation on corresponding layer of plastic which serves as carrier and are definitely connected with each other through intermediate glue layer to form packing laminate. owing to independent adjustment of thickness of gas-tight and light-tight layers, optimum combination of gas- and light-tightness can be obtained. Thanks to it packing laminate for each type of product to be packed can be made. EFFECT: enlarged operating capabilities. 8 cl, 1 dwg</p> |
