style="text-indent:25px">縫底紙袋按照袋邊，底部及封底方式不同，有開口縫底袋、開口粘合角底袋、閥式縫合袋、閥式扁平六角形端底粘合袋等四種紙袋型式?？p底紙袋在很大程度上是以其精美造型和裝潢來宣傳美化商品，提高商品的競爭性。由于縫底紙袋的造型和結(jié)構(gòu)設(shè)計(jì)往往由被包裝商品的形狀特點(diǎn)來確定，故其式樣和類型很多?？p底紙袋用于包裝的紙，要求強(qiáng)度高、含水率低、透氣性小、無腐蝕作用。用于食品包裝的紙還要求衛(wèi)生、無菌、無污染雜質(zhì)等?？p底紙袋主要是單面膠版印刷紙。紙面潔白光滑，但白度、緊度、平滑度低于銅版紙。印上文字、圖案后，可與黃板紙裱糊成紙盒?？p底紙袋以聚合級乙烯為原料，以有機(jī)過氧化物為媒介。</p><div

style="text-indent:25px">縫底紙袋是一種兼顧傳統(tǒng)思路與先進(jìn)思路的包裝袋，袋子的底部為方形，使袋子的整體效果可以與方底閥口袋媲美;開口為平口的，縫底紙袋適合于傳統(tǒng)的縫紉封口方式，紙張中間可以加一層塑料薄膜，用來包裝需要防潮的產(chǎn)品?？p底紙袋為防油紙袋印刷技術(shù)的防水性往往與紙質(zhì)的好壞有著直接的關(guān)系，紙質(zhì)好壞的辨別一般有3種方法：撕裂法：橫撕紙袋，有毛茬的為木漿紙，強(qiáng)度高;若撕裂口整齊沒有毛茬，則為草漿紙或木漿成分少，強(qiáng)度低。手搓法：把紙袋浸泡在水中一段時(shí)間，取出后用兩手對搓，不起毛或耐搓的表示紙質(zhì)好?；馃ǎ夯馃?，紙灰成型不散碎的紙質(zhì)好;紙灰碎而不成形的紙質(zhì)差。縫底紙袋可以根據(jù)客戶的要求制成一到六層，印刷和制袋一體化。上海特制皺紋紙縫底紙袋廠家定做</p><p
