八边封食品包装袋生产流程

一、进膜进行印刷(印刷时每一种颜色有一个板滚，板滚的雕刻是凹板雕刻)，在印刷时油墨是不停的流动的，因为油墨会凝结，在油墨印刷和膜进行印刷时镶嵌了一个刮刀，刮刀是对板滚凸出的地方刮去油墨，这样凹进去的板滚就能印刷。如果刮刀上沾有灰尘就会出现条状的油墨污染现象。对于点状的油墨污染现象是因为油墨在滚动印刷时油墨会溅到包装膜上而造成了点状的油墨污染。

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、膜印刷好后就开始进行复合，对于我公司生产的膜一般采用干湿复合法，就是将彩印好的膜涂上胶水后进入一个烘干，进行到2分钟然后和PE进行复合，复合的张力是5.6kg。我们公司采用的包装袋是两层复合。

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：对粘好胶水复合后的膜进行固化，固化的效果主要是将胶水能够牢牢的粘住，固化一般在50℃下固化24个小时。实际上就是将复合好的膜放在50℃的环境下存放24个小时。如果时间和温度不合要求就会出现膜复合不紧的现象。

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进行检品，检品就是将标准样板的印刷品输入电脑，然后将固化好的膜通过电脑控制的一个白色屏幕，出现不合格品直接将在膜上粘贴一个黑色的标志。

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、检品后的膜就进行分切

5、 The film after inspection is cut into sections

六、分切后的膜就进行制袋，制袋是通过机器直接将一张膜进行自动制袋，制袋的过程中进行自动的封边，并进行压紧。

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.
