復(fù)合膜塑料袋圖案印刷較為復(fù)雜，所以刷印的效果 直接應(yīng)響到塑料的質(zhì)量，圖案的印刷的效果又和版一直接的關(guān)系，所以一定要選擇技術(shù) 和質(zhì)量較好的制版廠來(lái)完成制版，以免給以后的塑料印刷造成一些麻煩，聚乙烯袋子印 刷較為簡(jiǎn)單，吹膜則為生產(chǎn)過(guò)程中重中之重，在調(diào)整膜的規(guī)格如寬度和膜厚度有較強(qiáng)的 技術(shù)性，如果卡不好這一關(guān)有可能造成膜薄導(dǎo)制檢驗(yàn)為不合格產(chǎn)品或吹的過(guò)厚剛會(huì)賠掉 過(guò)厚部分料的錢(qián)。吹膜生產(chǎn)所用的機(jī)器也效為簡(jiǎn)單，現(xiàn)在復(fù)合袋所用的機(jī)器大多都為全 電腦控制的，所以是精度都比較高，聚乙烯袋和復(fù)合袋不僅是生產(chǎn)機(jī)器上有有大的差異 ，就是材料和所用油墨也不相同，聚乙烯袋大都便用表印油墨，復(fù)合袋則用里印油墨， 復(fù)合袋是先印刷后再?gòu)?fù)膜，所以油墨在幾層膜的中間，裝食品時(shí)油墨不會(huì)污染到食品， 當(dāng)然塑料印刷當(dāng)中因?yàn)榭蛻裟敲?，其中水份也很大，比如有一些塑料廠做抽真空袋 ，他們則選用了PE共擠膜這樣成本是減少了很多，但是效果遠(yuǎn)遠(yuǎn)比不上尼龍

The pattern printing of composite film plastic bags is relatively complicated, so the effect of brushing directly affects the quality of the plastic. The effect of pattern printing is closely related to the plate. Therefore, it is necessary to select a plate making factory with better technology and quality to complete the plate making, so as to avoid causing some trouble to the plastic printing in the future. The printing of polyethylene bags is relatively simple, and film blowing is the most important in the production process, There is a strong technicality in adjusting the specifications of the film, such as the width and the thickness of the film. If the card is not properly stuck, it may cause the film thin guide inspection to be unqualified products or the blown film is too thick, and the money of the excessively thick material will be lost. The machines used for film blowing production are also simple. Most of the machines used for composite bags are controlled by computers, so the accuracy is relatively high. Polyethylene bags and composite bags are not only different in production machines, but also different in materials and inks. Most polyethylene bags use surface printing ink, while composite bags use inner printing ink. Composite bags are printed first and then laminated, so the ink is in the middle of several layers of films, The ink will not pollute the food when the food is loaded. Of course, because the customers are so professional in plastic printing, the water content is also very large. For example, some plastic factories make vacuum bags, and they use PE coextrusion film, which reduces the cost a lot, but the effect is far less than that of nylon

可能使用中會(huì)出現(xiàn)漏氣等很多問(wèn)題，PET塑料袋制作則選用PET轉(zhuǎn)移膜為原材料，氣密性就沒(méi)那么好，充淡氣的袋子可會(huì)漏氣，厚度有可能達(dá)不到客戶所預(yù)訂的厚度，也有可能材質(zhì)上有差異，所以客戶也應(yīng)了解一些有關(guān)塑料包裝料的知識(shí)，了解塑料袋加工工藝流程，我們可以對(duì)塑料袋加工有個(gè)更好的了解。

There may be many problems such as air leakage during use. The pet transfer film is used as the raw material for the production of PET plastic bags, so the air tightness is not so good. The bags filled with light air may leak, and the thickness may not reach the thickness ordered by the customer, or there may be differences in the material. Therefore, the customer should also know some professional knowledge about plastic packaging materials and know the processing process of plastic bags, We can have a better understanding of plastic bag processing.
