中文摘要:
      目的 研究EPE包装袋的热封质量与热封参数(电热丝直径、热封时间、热封压力)的关系,分析弹性包装材料热封过程的特性。方法 通过观察显微封口形貌,比较不同参数下的热封强度,研究热封参数对珍珠棉热封强度的影响,并分析其原因。结果 在热封1.0 mm珍珠棉过程中使用直径为0.8 mm电热丝,热封压力为0.2 MPa,热封时间为2 s时,热封质量最好、效率较高。结论 弹性材料的可压缩性导致封切压力对热封强度的影响随电热丝直径的增加而明显增加,弹性材料的回弹特性使电热丝直径以及热封时间对其热封缺陷产生更加显著的直接影响。
英文摘要:
      The work aims to study the relationship between the heat sealing quality of EPE packaging bag and heat sealing parameters (electric wire diameter, heat sealing time, heat sealing pressure), and analyze the characteristics of elastic packaging materials heat sealing process. The influence of heat sealing parameters on the heat sealing strength of pearl wool was studied by observing the morphology of micro sealing and comparing the heat sealing strength with different parameters, and its cause was analyzed. In the process of heat sealing the 1.0 mm pearl wool with the 0.8 mm electric wire when the heat sealing was 0.2 MPa and heat sealing time was 2 s, the heat sealing quality was the best and the efficiency was the highest. The compressibility of elastic material causes the influence of sealing pressure on the heat sealing strength to increase significantly with the increase of the electric wire diameter. With the springback characteristics of the elastic material, the electric wire diameter and the heat sealing time have more significantly direct influence on the heat sealing defects.
