ABSTRACT:
The present invention relates to a polyolefin-based resin composition for the calendering process which can be directly printed without applying an adhesive since the surface printability is improved.The present invention provides a polyolefin-based resin composition for the calendering process comprising: 3 to 95 weight percent, based on total weight of said polyolefin-based resin composition, of a high impact polyolefin resin; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of an acrylate functional polymer; 1 to 30 weight percent, based on total weight of said polyolefin-based resin composition, of a polyolefin-based thermoplastic elastomer; 1 to 50 weight percent, based on total weight of said polyolefin-based resin composition, of a mineral filler; and 0.1 to 5.0 weight percent, based on total weight of said polyolefin-based resin composition, of a lubricant.By the present invention, it is possible to remarkably improve the surface printability of the polyolefin-based sheet or film and thereby, to achieve direct printing without need of an adhesive. Also, since a production line for applying an adhesive is not needed, it is possible to reduce the production cost and to increase productivity. Further, the present invention can substitute for decoration sheets, printing papers, labels and the like which have been composed of PVC and thus, is environmentally friendly.
