style="text-indent:25px">縫底紙袋內(nèi)容物的影響，有些產(chǎn)品為粉末裝，在進(jìn)灌裝時(shí)易沾污封口，例如，當(dāng)采用LDPE材料作為內(nèi)層料時(shí)，發(fā)現(xiàn)封口處易破裂。這是因?yàn)長(zhǎng)DPE對(duì)夾雜物的熱封性就不是很好，這時(shí)就要更換內(nèi)層膜材料（如LLDPE、mPE等抗污染熱封性能都較好）或增加材料的厚度就可以提高熱封強(qiáng)度?？p底紙袋在復(fù)合聚乙烯薄膜過程中，聚乙烯經(jīng)熱壓輥擠壓后有析出的現(xiàn)象，一層白白的象碎粉白狀，這種現(xiàn)象是聚乙烯在生產(chǎn)過程中，加入一定量的潤(rùn)滑劑，是一些低熔點(diǎn)的蠟，容易析出至薄膜表面。這層低熔點(diǎn)的蠟析出后較直接的危害就是地削弱了復(fù)合強(qiáng)度（有待重新整理），也地減弱了熱封強(qiáng)度，特別在封邊位置，造成易開口，離層。北京紙塑復(fù)合布縫底紙袋價(jià)格</p><p
