POLYPROPYLENIC RESIN COMPOSITION, T-DIE FILM AND MANUFACTURING METHOD OF T-DIE FILM |
摘要 |
PROBLEM TO BE SOLVED: To provide a polypropylenic resin capable of rectifying defective external appearances of a film even in T-die film processing using a polypropylenic resin having a sharp molecular weight distribution, a T-die film composed of the same, and a manufacturing method of a T-die film permitting rectification in defective external appearances of a film even when a polypropylenic resin having a sharp molecular weight distribution is employed. SOLUTION: The polypropylenic resin composition comprises 100 pts.wt. of a propylene polymer resin (A) having a die swell ratio of less than 1.70 and 0.01-45 pts.wt. of a propylene polymer resin (B) having a die shell ratio of at least 1.80. The T-die film is composed of the polypropylenic resin composition. The manufacturing method of the T-die film comprises using the polypropylenic resin composition. |
