<p>PURPOSE:To obtain a packing material having no stickness, excellent in scratch resistance, cold impact resistance, twist properties, pinhole resistance and interlaminar strength, having characteristics capable of corresponding to the rapid time limit of delivery and capable of being supplied inexpensively by mutually laminating oriented plastic films. CONSTITUTION:A packing material is constituted of the first support base material composed of a oriented plastic film positioned on the surface side thereof, the heat sealant resin layer positioned on the rear side thereof and the second support base material composed of a oriented plastic film positioned between the first support base material and the heat sealant resin layer. The treatment due to an anchor coating agent is applied to the rear of the first support base material while printing decorative processing and the treatment due to the anchor coating agent are applied to the surface of the second support base layer and the treatment due to the anchor coating agent is applied to the rear of the second support base material and the rear of the first support base material is laminated to the surface of the second support base material through an extrusion layer of a polylefinic resin.</p> |
