摘　　要：目的传统塑料包装透气性较差,不利于环保,为解决这些缺陷,研发一种塑料-细竹丝模压异型板件的新型外固定用包装材料,并通过实验方法确定其性能。方法首先,介绍塑料-细竹丝模压异型板件新型包装材料的特点与成型工艺;其次,通过实验对塑料-细竹丝模压异型板件包装材料制造时最佳竹塑比进行确定;最后,利用概率设计理论求解出异型板件包装材料主方向的弹性模量,并通过实验对其理论公式进行验证。结果当竹塑比值为0.150时,异型板件包装材料的各项性能较好,上异型板件包装材料单位质量的最大抗压力平均值达到4.33 kN/kg,下异型板件包装材料单位质量的最大抗压力平均值达到5.26 kN/kg。力学实验结果显示,所建立异型板件包装材料的弹性模量理论求解公式正确,且细竹丝的加入提高了原有包装材料的力学性能。结论新型包装材料具有较好的稳定性和透气性,更加环保,是传统塑料包装材料的理想换代产品。文中研究将推进我国异型板件包装材料工业化的发展,并为异型板件包装材料产业化加工设备的设计制造提供理论和实验依据。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 characte-ristics 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 spe-cial-shaped plates was figured out by using probability design theory,and its theoretical formula was verified by experi-ments.The experimental results showed that when the bamboo to plastic ratio was 0.150,properties of the packaging ma-terial 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 ma-terial 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 ma-terials for special-shaped plates in China,and will provide theoretical and experimental basis for the design and manu-facture of industrial processing equipment of packaging materials for special-shaped plates.
