    摘要: A method for manufacturing a wide film comprises a casting operation, a stretching operation, and a trimming operation. The casting operation is a process of casting a film using a wide casting belt including a central belt, a left belt having a right end formed integrally with a left end of the central belt through a left joint in a length direction of the central belt, and a right belt having a left end formed integrally with a right end of the central belt through a right joint in the length direction of the central belt. The stretching operation is a process of stretching a film stripped off from the wide casting belt using a tenter. The trimming operation is a process of trimming predetermined parts of left and right sides of the stretched film. In the trimming operation, mark parts by the left and right joints are also trimmed.

    摘要: Provided is a resin composition for a sheet to an eco-friendly poly(alkylene carbonate) resin composition containing a poly(alkylene carbonate) resin developed by efficiently utilizing carbon dioxide, which is a major contributor to global warming, as a main material, and including an strength controller, a flexibilizer and a filler. The present invention can solve problems related to environment harmfulness of the existing polyvinyl chloride resin products and have excellent flameproofing property and stretching property. In addition, the present invention can employ a calender processing method, which allows mass production and overcome a small production type extrusion processing method, which is regarded as the biggest disadvantage of thermoplastics emerging as alternatives for the existing polyvinyl chloride products.
