| titleOfInvention | Manufacturing method of white porous polyester film instead of paper |
| abstract | The present invention relates to a method for producing a paper-substituted white porous polyester film, wherein in preparing a white paper-substituted white porous film mainly composed of a polyester resin, the size, shape and distribution of pores present in the film are appropriate. It provides a method of manufacturing a white porous polyester film for paper substitutes not only excellent in whiteness, texture, and light weight, but also greatly improved the stiffness peculiar to the polyester film to exhibit a smooth texture similar to paper. In order to achieve the above object, the present invention is a polypropylene terephthalate or a polybutylene terephthalate alone or a mixture of a polyester resin containing inorganic fine particles and polyolefin resin primary mixing To prepare a resin mixture Paper, characterized in that it comprises a step of mixing by mixing the succinic anhydride or maleic anhydride graft polymerized elastomer copolymer at 0.3 to 2.0% by weight based on the total weight of the resin mixture, followed by melting, extrusion and stretching Provided is a method for producing a surrogate white porous polyester film. |
