| The traditional plastic packaging has poor permeability, and is not conducive to environmental protection. In order to solve these defects, we developed a new type of packaging material for external fixation of plastic-fine bamboo molded special-shaped plates, and determined its performance by experimental method. In the paper, Firstly, the characteristics and forming process of this new type packaging material for plastic-fine bamboo molded special-shaped plates were introduced. Secondly, the optimum bamboo to plastic ratio of the new packaging material during its manufacturing was determined by experiments. Finally, the elastic modulus of the main direction of the packaging material for the special-shaped plates was figured out by using probability design theory, and its theoretical formula was verified by experiments. The experimental results showed that when the bamboo to plastic ratio was 0.150, properties of the packaging material for special-shaped plates were better. The average value of the maximum pressure resistance per unit mass of the upper plate packaging material reached 4.33 kN/kg, and that of the lower plate packaging material reached 5.26 kN/kg. The results of mechanical experiment showed that the formula of elastic modulus theory was correct, and the addition of fine bamboo filaments improved the mechanical properties of the original packaging material. The new packaging material has better stability and air permeability, and is more environmentally-friendly, which is an ideal substitute for the traditional plastic packaging materials. The study will promote the development of the industrialization of packaging materials for special-shaped plates in China, and will provide theoretical and experimental basis for the design and manufacture of industrial processing equipment of packaging materials for special-shaped plates. |
