八邊封食品包裝袋生產(chǎn)流程

來源：http:/// 日期：2024-06-06

一、進膜進行印刷(印刷時每一種顏色有一個板滾，板滾的雕刻是凹板雕刻)，在印刷時油墨是不停的流動的，因為油墨會凝結(jié)，在油墨印刷和膜進行印刷時鑲嵌了一個刮刀，刮刀是對板滾凸出的地方刮去油墨，這樣凹進去的板滾就能印刷。如果刮刀上沾有灰塵就會出現(xiàn)條狀的油墨污染現(xiàn)象。對于點狀的油墨污染現(xiàn)象是因為油墨在滾動印刷時油墨會濺到包裝膜上而造成了點狀的油墨污染。

1、 When printing on a film (each color has a plate roller, and the engraving of the plate roller is concave plate engraving), the ink flows continuously during printing because the ink will condense. During ink printing and film printing, a scraper is embedded to scrape off the ink on the protruding areas of the plate roller, so that the concave plate roller can be printed. If there is dust on the scraper, there will be strip like ink contamination. The phenomenon of dot shaped ink pollution is caused by ink splashing onto the packaging film during rolling printing, resulting in dot shaped ink pollution.

二、膜印刷好后就開始進行復(fù)合，對于我公司生產(chǎn)的膜一般采用干濕復(fù)合法，就是將彩印好的膜涂上膠水后進入一個烘干，進行到2分鐘然后和PE進行復(fù)合，復(fù)合的張力是5.6kg。我們公司采用的包裝袋是兩層復(fù)合。

2、 After the film is printed, the composite process begins. For the films produced by our company, the dry wet composite method is generally used. The color printed film is coated with glue and then dried for 2 minutes before being composite with PE. The composite tension is 5.6kg. Our company uses a two-layer composite packaging bag.

三、固化：對粘好膠水復(fù)合后的膜進行固化，固化的效果主要是將膠水能夠牢牢的粘住，固化一般在50℃下固化24個小時。實際上就是將復(fù)合好的膜放在50℃的環(huán)境下存放24個小時。如果時間和溫度不合要求就會出現(xiàn)膜復(fù)合不緊的現(xiàn)象。

3、 Curing: Cure the film after being glued and compounded. The main effect of curing is to firmly adhere the adhesive, which is usually cured at 50 ℃ for 24 hours. In fact, it is to store the composite film at 50 ℃ for 24 hours. If the time and temperature do not meet the requirements, there will be a phenomenon of loose membrane composite.

四、固化好后的膜然后就進行檢品，檢品就是將標準樣板的印刷品輸入電腦，然后將固化好的膜通過電腦控制的一個白色屏幕，出現(xiàn)不合格品直接將在膜上粘貼一個黑色的標志。

4、 After curing, the film is then inspected. The inspection involves inputting the printed material of the standard template into the computer, and then passing the cured film through a white screen controlled by the computer. If any unqualified products are found, a black mark will be directly pasted on the film.

五、檢品后的膜就進行分切

5、 The film after inspection is cut into sections

六、分切后的膜就進行制袋，制袋是通過機器直接將一張膜進行自動制袋，制袋的過程中進行自動的封邊，并進行壓緊。

6、 The cut film is then used for bag making. Bag making is achieved by directly using a machine to automatically seal and compress a piece of film during the bag making process.
