Definitions

  • the present invention relates to a biodegradable protein and starch based thermoplastic composition with natural cellulosic fiber.
  • the invention can be prepared as a biodegradable low ratio expanded foam useful as a low density foam packaging material or food container.
  • biodegradable thermoplastic compositions which can be recycled or ingested. It would be a further advancement in the art to provide biodegradable thermoplastic compositions which enhance the soil, if disposed therein.
  • the present invention provides protein/starch thermoplastic compositions which are biodegradable, recyclable, light weight, strong, and water resistant.
  • Chemical modification of protein and starch can be used to improve the physical and chemical properties of compositions made therefrom, such as flexibility, thermal stability, water resistance, compatibility between protein and starch, processing flowability, aging resistance, etc.
  • acid modified soy protein greatly improves the surface hydrophobicity.
  • the foaming capacity and foam stability of soy protein are improved by succinylated and acetylated soy protein.
  • the compatibility of soy protein with starch becomes worse with increased high amylose starch content.
  • the compatibility of high amylose starch with soy protein can be improved by modification of the protein and/or starch.
  • a low ratio expanded foam was made of a protein/starch composition formulated with soy protein isolate, corn starch, glycerol, water, chemical blowing agent (BIF) , nucleating agent (talc, CaC0 3 ) , lubricant (lecithin) , and various natural cellulosic fibers (bagasse, chopped corn straw, chopped straw, wood fibers, grass fibers) as shown in Table 3 below.
  • -25- 4/Zone 5 (die) 110/130/150/160/135°C.
  • the screw speed was 40 rpm.
  • the take off speed of the foam sheet was 46 inch/min.
