摘要： A hydrophobic biodegradable material contains host material and foamer. The host material is a product by melting a mixture, which comprises polyol, polyvinyl alcohol containing water, and starch contained or not. Said polyvinyl alcohol is a hydrophobic polyvinyl alcohol. The host material in the hydrophobic biodegradable material of the present invention is a product by melting the swollen hydrophobic polyvinyl alcohol, polyol and starch that is chosen to be contained or not. The melt temperature of the obtained host material is 130-210 , which is much lower than its decomposition temperature which is 240-420 , so it may be in molten state, and in a true sense can be extrusion-granulated and foaming-molded. The resulting foamed articles, produced by the hydrophobic biodegradable material of the present invention, have good expansion ratio that is more than 45%, compressive strength which is not less than 35 Kpa, water resistance and biodegradability.

摘要： A hydrophobic biodegradable material is a product by melting a mixture, which comprises polyol, polyvinyl alcohol containing water, and starch contained or not. Said polyvinyl alcohol is a hydrophobic polyvinyl alcohol. The amount of polyol is 25-45% by weight, based on the sum of the mixture. Because the hydrophobic biodegradable of the present invention is a kind of product by melting a mixture, the melt temperature of the hydrophobic biodegradable material of the present invention is 130-210 , which is much lower than its decomposition temperature which is 260-420 , so said material may be in molten state. Therefore, the hydrophobic biodegradable material of the present invention can be produced into film shaped articles by blow molding, and the resulting film shaped articles have good tensile strength, elongation at break, right angle tear strength, water resistance and rate of biodegradation.

The main body of the die comprises feed openings and a main flow channel which is located in the main body of the die and interconnects the feed opening and annular port mold. There are many feed openings, and each of them connects to one or more main flow channel. The main flow channel connected with different feed openings connects to different regions of the annular port mold. The regions distribute along the circumferential direction of the annular port mold, and the cross section of the regions is a fan link shape. The film-blowing machine includes the above die and several screw extruders. The mulching film made by the machine consists of at least two different materials which locate in the film side by side.
