As a means of improving the transparency of the film, two-stage air cooling method, water cooling method or T-cooling method for blown film is used.
A method of rapid cooling using a die molding method or the like is known. However, in general, L-LDPK films are prone to blocking, and in particular, when the transparency is improved by the above-mentioned molding method, the blocking resistance tends to drop markedly.Especially in blown film molding, the film after molding cannot be opened. There was a possibility that something would happen.

On the other hand, when thermoplastic resins such as polyolefins, including L-LDpH, are molded at high temperatures of 200 to 300°C, a heat stabilizer is always used in combination. Tetrakis[methylene-5-(5,5-di-t-butyl-4-hydroxy-phenyl)propionate comethane] is known as one of the best heat-resistant stabilizers, but surprisingly, It has been found that when a heat stabilizer is used in combination, the blocking resistance is significantly reduced. Therefore, the present inventor has developed a method that has heat resistance, blocking resistance,
As a result of studies aimed at obtaining an ethylene/a-olefin copolymer for film forming with excellent transparency, the present invention was achieved.

.. 1 to 0.2 mnl, medium is 0.2 to Q, 3
mm, large means Q, 3 mm or more. Heat resistance is considered to be good if the number of large, medium, or small fisheyes does not increase when a continuously molded film is sampled every hour and subjected to a scanning flaw detector. Also, observing the side color of the rolled film and not seeing any change is proof that the film has good heat resistance.
