封口强度对塑料包装材料来讲是一个重要性能指标,任何一种软包装材料都要制作成包装袋才能用于包装。热封三要素为:热封温度、热封时间和热封压力。确定合适的热封工艺参数是保证封口质量和提高生产效率的关键。本文通过测试不同温度、不同速率下包装材料的封口强度及收缩率,确定最佳的工艺参数组合。
Sealing strength of plastic packaging materials in terms of an important performance indicators, any kind of flexible packaging materials must be made into bags for packaging. Heat sealing three elements: heat sealing temperature, heat sealing time and heat sealing pressure. To determine the appropriate heat sealing process parameters is to ensure the quality of the seal and improve the production efficiency of the key. In this paper, by testing the sealing strength and shrinkage of packaging materials at different temperatures and different rates, to determine the best combination of process parameters.
