Abstract

PURPOSE: To provide a composite structural sheet which accommodates suitable adhesive and preferable release properties without coating bonding agent onto various plastics.
CONSTITUTION: This sheet is composed of a surface material 1, a core material 2, and a syllable layer 3 with gravure film 4 formed on the back surface of the surface material 1 and bonded via a bonding agent film 5 to the core material 2. The core material 2 is secured through a binder layer 6 to the layer 3. A corona discharge treatment layer 7 is formed on the surface of the layer 3. This layer 3 is formed on ethylene-vinyl acetate complymer film containing 5 to 10 by weight % of vinyl acetate. The layer 7 is provided on the surface making contact with the adhesive surface of the ethylene-vinyl acetate complymer film or packaging container or the like used as the layer 3.
