Tarpaulin having improved flexibility, adhesion, and surface strength and manufacturing method therefor

A method of manufacturing a tarpaulin, the method comprising:

• kneading and melting a resin raw material mixture containing a polypropylene (PP) and a low density polyethylene (LDPE) in a cylinder including a screw;
• providing the molten resin raw material mixture to a T-die in a constant amount;
• forming a resin layer by passing the molten resin raw material mixture through the T-die;
• and
• bonding a fabric layer including a high density polyethylene (HDPE) multifilament yarn, a PP multifilament yarn arranged to cross the HDPE multifilament yarn, and a polyethylene terephthalate (PET) ground yarn binding the HDPE multifilament yarn and the PP multifilament yarn and the resin film,
• wherein the step of kneading the resin raw material mixture, the step of providing the molten resin raw material mixture to the T-die and the step of forming the resin film are performed at 260° C. or lower,
• wherein temperatures of the resin film forming of the T-die are vary depending on the regions of T-die,
• wherein a temperature of a first region of T-die is 220° C. to 240° C., and a second temperature of a second region of the T-die is 230° C. to 250° C.,
• wherein the resin layer includes 30% to 50% by weight of the LDPE, 30% to 50% by weight of the PP, and 10% to 20% by weight of an olefin-based copolymer, and
• wherein the olefin-based copolymer is a copolymer of a monomer mixture containing 15% to 20% by weight of a ethylene monomer and 80% to 85% by weight of a propylene monomer.
