Edible Plastics/Films or Biopolymers from Food Materials Nguyen Thi Huong Thao1,a, Dang Viet Hung2,b, Nguyen Thi Minh Tu1,c and Luong Hong Nga1,d* 1Faculty of Food Engineering, School of Chemistry and Life Science, Hanoi University of Science and Technology, Hanoi, Vietnam 2Faculty of Chemical engineering, School of Chemistry and Life Science, Hanoi University of Science and Technology, Hanoi, Vietnam a thao.nth2002@gmail.com, bhung.dangviet@hust.edu.vn, cu.nguyenthiminh@hust.edu.vn, Corresponding Author: d*nga.luonghong@hust.edu.vn Keywords: Biopolymer, edible plastic, hydrocolloid, polysaccharides, physicochemical properties, mechanical properties.
Edible plastics/films or biopolymers are biodegradable materials which are normally applied as food packaging.
This shows the potential of using these three types of polysaccharides as the biopolymer materials for the edible films [10].
Materials with a higher elongation at break percentage have higher ductility.

So based on transformed-section method, the section composed with steel and concrete can be transformed to one section made of supposing material.
Transformed Section General transformed section is converting the two materials, the bar and concrete, into a same imaginary material which assure the tension and compression performance unchanged.

However, thermoforming trays are made of plastic materials and are disposable packaging.
Protection and preservation function of these containers in terms of gas and moisture barrier, odor and taste barrier, or safety protection from microorganism are necessary, therefore the usage of packaging made of polymer materials cannot be avoided.
Trade-off between a significant function of food protection using plastic packages and the environmental impact has continued until the substitute packaging materials like biomaterials could not overcome.
