 Product Type                                                                     

   biodegradable starch based plastic resin

   Film blowing type

Product Description                                                              

   The resin  base on corn starch which is a kind of renewable material .Its finished products have a good mechanical strength ,glossy surface ,perfect elongation strength ,good flexibility and toughness . Applications are bags (compost bags, lawn & leaf bags, pet waste bags, carry-out bags), agricultural film, consumer and industrial packaging.

Procession Technology                                                           

a.      the screw rotation should be slow at first ,and then adjust the screw rotation faster to match the request.b.      fleshly blown film product feels a little brittle and crisp ,due to dehydration in production ,after 24 hours ,its function regains to normal plastics . c.       the preferred blow-up ratio is 1:2.5, the height from die of orifice to the nip roll should be higher than 2.5m which to insure full cooling and prevent film blocking.d.      using blowing temperature for reference
