各種材料的(de)(de)熔(rong)融(rong)(rong)溫(wen)度(du)(du)(du)直接決(jue)定復(fu)(fu)合(he)袋的(de)(de)低熱(re)(re)封(feng)(feng)(feng)(feng)溫(wen)度(du)(du)(du)，而熱(re)(re)封(feng)(feng)(feng)(feng)溫(wen)度(du)(du)(du)對熱(re)(re)封(feng)(feng)(feng)(feng)強(qiang)度(du)(du)(du)的(de)(de)影(ying)(ying)響(xiang)為(wei)直接，在(zai)實際生(sheng)(sheng)產(chan)過程中，由(you)于受到熱(re)(re)封(feng)(feng)(feng)(feng)壓力，制(zhi)袋速(su)度(du)(du)(du)及復(fu)(fu)合(he)基材的(de)(de)厚度(du)(du)(du)等多方面因素的(de)(de)影(ying)(ying)響(xiang)，熱(re)(re)封(feng)(feng)(feng)(feng)溫(wen)度(du)(du)(du)往往要高于熱(re)(re)封(feng)(feng)(feng)(feng)材料的(de)(de)熔(rong)融(rong)(rong)溫(wen)度(du)(du)(du)。因為(wei)熱(re)(re)封(feng)(feng)(feng)(feng)溫(wen)度(du)(du)(du)若(ruo)低于熱(re)(re)封(feng)(feng)(feng)(feng)材料的(de)(de)軟化點(即熔(rong)融(rong)(rong)溫(wen)度(du)(du)(du))，則無論(lun)怎樣加(jia)大壓力或延長熱(re)(re)封(feng)(feng)(feng)(feng)時間，均不能使熱(re)(re)封(feng)(feng)(feng)(feng)層封(feng)(feng)(feng)(feng)合(he)，但是若(ruo)熱(re)(re)封(feng)(feng)(feng)(feng)溫(wen)度(du)(du)(du)過高，又極易損傷焊邊處的(de)(de)熱(re)(re)封(feng)(feng)(feng)(feng)材料，使之熔(rong)融(rong)(rong)擠出，產(chan)生(sheng)(sheng)“根切"現象，大大降低封(feng)(feng)(feng)(feng)口的(de)(de)熱(re)(re)封(feng)(feng)(feng)(feng)強(qiang)度(du)(du)(du)和復(fu)(fu)合(he)袋的(de)(de)耐沖擊性能。
