設(shè)計(jì)產(chǎn)品的濟(jì)南復(fù)合袋包裝工藝時，除了對各種基材的正確選擇外，對復(fù)合用黏合劑的選擇也關(guān)重要，要根據(jù)產(chǎn)品的用途、構(gòu)成、后加工條件、質(zhì)量要求品質(zhì)等進(jìn)行選擇。如選錯膠粘劑，無論復(fù)合加工技術(shù)多么完善，也會引起粘結(jié)不良、以及后加工中的粘結(jié)力低下、復(fù)合不牢、漏液、破袋等故障的發(fā)生。

When designing the Jinan composite bag packaging process of products, in addition to the correct selection of various base materials, the selection of composite adhesives is also crucial. The selection should be based on the use, composition, post-processing conditions, quality requirements and quality of the products. If the wrong adhesive is selected, no matter how perfect the composite processing technology is, it will also lead to poor adhesion, low adhesion, weak bonding, liquid leakage, broken bags and other failures in post-processing.

對日化軟包裝用膠粘劑的選擇要考慮多種因素，一般來說，作為復(fù)合膠應(yīng)滿足下條件：

A variety of factors should be considered in the selection of adhesives for flexible packaging of daily chemicals. Generally speaking, as a composite adhesive, the following conditions should be met:

①；

① Non-toxic;

②包裝液體后無有害萃取物出現(xiàn)；

② There is no harmful extract after packaging liquid;

③適用食品貯存的溫度要求；

③ Applicable temperature requirements for food storage;

④耐候性好，不發(fā)黃起泡，不粉化脫層；

④ Good weather resistance, no yellowing and blistering, no pulverization and delamination;

⑤耐油、香精、醋和酒精；

⑤ Resistant to oil, essence, vinegar and alcohol;

⑥不侵蝕印刷圖案油墨，并對油墨有較高親和力。

⑥ It does not corrode printing ink and has high affinity for printing ink.

另外柔軟性、可操作性、粘力持久性、抗介質(zhì)侵蝕性和衛(wèi)生性等也是不容忽視的。就抗介質(zhì)侵蝕性而言，內(nèi)容物中含有香辛料，醇、水、糖、脂肪酸等，其特性各異，有可能透過復(fù)合膜內(nèi)層滲入膠層，引起腐蝕破壞作用，導(dǎo)致包裝袋脫層、破裂以致失效。為此，膠粘劑必須具有抵御上述物質(zhì)侵蝕的能力，始終保持足夠的黏接剝離強(qiáng)度。

In addition, softness, operability, adhesion durability, medium erosion resistance and health safety can not be ignored. In terms of medium corrosion resistance, the contents contain spices, alcohol, water, sugar, fatty acid, etc., with different characteristics. It is possible to penetrate into the adhesive layer through the inner layer of the composite film, causing corrosion damage, leading to delamination, cracking and failure of the packaging bag. For this reason, the adhesive must have the ability to resist the erosion of the above substances and always maintain sufficient bonding and peeling strength.
