<p>PURPOSE:To effectively utilize regenerated materials which are recovered in connection with the environmental problem and waste disposal, and material conservation. CONSTITUTION:A regenerated material layer 1 which is formed of regenerated synthetic resin material is provided as an internal layer and a raw material layer 2 formed of raw synthetic resin material is provided on each side of the internal layer, as a surface layer, to form a three-layer structure. And since a raw material layer is provided as a surface layer, thermal bonding strength, which is an important quality of a band, can be maintained at the same level of conventional raw material for general purposes.</p> |
