style="text-indent:25px">縫底紙袋熱封溫度對熱封強(qiáng)度的影響較直接，各種材料的熔融溫度高低，直接決定復(fù)合袋的較低熱封溫度。在實(shí)際生產(chǎn)過程中，由于熱封壓力、制袋機(jī)速以及復(fù)合基材的厚度等多方面的影響，實(shí)際采用的熱封溫度往往要高于熱封材料的熔融溫度。熱封的壓力越小，要求熱封溫度越高，機(jī)速越快，復(fù)合膜的面層材料越厚，要求的熱封溫度也越高。熱封溫度若低于熱封材料的軟化點(diǎn)，則無論怎樣加大壓力或延長熱封時(shí)間，均不能使熱封層真正封合。但是，如果熱封溫度過高，又極易損傷焊邊處的熱封材料，熔融擠出產(chǎn)生"根切"現(xiàn)象（俗稱"斷根"），降低了封口的熱封強(qiáng)和復(fù)合袋子的耐沖擊性能。天津建材縫底紙袋定制批發(fā)公司</p><p
