style="text-indent:25px">縫底紙袋熱封時(shí)間主要由制袋機(jī)的速度決定。速度快，熱封時(shí)間就短；速度慢，熱封時(shí)間就長(zhǎng)。熱封時(shí)間也是影響焊縫封合強(qiáng)度和外觀的一個(gè)關(guān)鍵因素。相同的熱封溫度和壓力下，熱封時(shí)間長(zhǎng)，則熱封層熔合更充分，結(jié)合更牢固；但熱封時(shí)間太長(zhǎng)，容易造成焊縫起皺變形，影響平整度和外觀。熱封后的焊縫若冷卻不好，不但會(huì)影響焊疑的外觀平整度，而且對(duì)熱封強(qiáng)度有一定的影響。冷卻過(guò)程就是通過(guò)在一定的壓力下，用較低的溫度對(duì)剛?cè)廴跓岱夂蟮暮缚p進(jìn)行定形。因此，壓力不夠，冷卻和循環(huán)不暢，循環(huán)量不夠，水溫太高或冷卻不及時(shí)，都會(huì)致使冷卻不良，熱封強(qiáng)度降低?？p底紙袋按照袋邊，底部及封底方式不同，有很多形式。河南開(kāi)口縫底袋供應(yīng)</p><p
