The objective of this thesis is therefore to develop a bioplastic film based on corn starch and compare it with petrochemical plastics and paper bags in order to answer the following problem : Why replace petrochemical plastics in an environmentally friendly way ? Indeed, finds that bioplastics are better for the environment than petrochemical plastics. They are less polluting and degrade more quickly.frThesis
