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.

Introduction With the progress of science and technology, new materials appear constantly, the composite material has become more and more important in the field of modern high-tech or traditional engineering.
When the composite beam is under the pure bending state, the strain on the cross section are distributed linearly, but due to the anisotropy of composite materials.
