摘要： The thermal welding of laminated packing material (31, 32) composed of foam
(102) supported by a porous substrate sheet is improved by applying on the surface of
the substrate in contact with the foam a barrier layer such as alcohol polyvinyl to prevent
the foam (102) merger seeps through the substrate. Alternatively support for the foam
may be a non-poureux film such as polyethylene terephthalate. In a variant using a cold
welding, the face of the foam supported foam packing sheets have a layer of
nonadhesive cohesion may contain an inhibitor of the volatile corrosion improved and / or
anti-static compositions do not shorten the duration storage stability desous in six
months. Such a composition is a mixture of dicyclohexylamine with 2-amino-2-lower alkyl-
1,3-propadiole. Preferably there is also added a protective colloid such as
polyvinylpyrrolidone to improve the compatibility of the volatile corrosion inhibiting
agent with the rubber latex conférantles nonadhesive cohesion characteristics. The
thermal welding of the packaging sheet can be carried out using hot melt pads (39 and
41).
