设计产品的济南复合袋包装工艺时，除了对各种基材的正确选择外，对复合用黏合剂的选择也关重要，要根据产品的用途、构成、后加工条件、质量要求品质等进行选择。如选错胶粘剂，无论复合加工技术多么完善，也会引起粘结不良、以及后加工中的粘结力低下、复合不牢、漏液、破袋等故障的发生。

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.

对日化软包装用胶粘剂的选择要考虑多种因素，一般来说，作为复合胶应满足下条件：

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包装液体后无有害萃取物出现；

② There is no harmful extract after packaging liquid;

③适用食品贮存的温度要求；

③ Applicable temperature requirements for food storage;

④耐候性好，不发黄起泡，不粉化脱层；

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不侵蚀印刷图案油墨，并对油墨有较高亲和力。

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

另外柔软性、可操作性、粘力持久性、抗介质侵蚀性和卫生性等也是不容忽视的。就抗介质侵蚀性而言，内容物中含有香辛料，醇、水、糖、脂肪酸等，其特性各异，有可能透过复合膜内层渗入胶层，引起腐蚀破坏作用，导致包装袋脱层、破裂以致失效。为此，胶粘剂必须具有抵御上述物质侵蚀的能力，始终保持足够的黏接剥离强度。

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.
