Many guests will have a question. We clearly want to make packaging bags, but they roll film for me, which has caused some misunderstanding. In fact, the automatic packaging film is also a kind of packaging bag. It is the last process of making packaging bags. In simple terms, there is one less process of making bags. The advantage is that the cost is lower than making bags, and many small bags can be made at the same price. We all know that the smaller the product is, the more packaging bags are needed, such as snack packaging bags, candy packaging bags, cereal packaging bags, etc. Therefore, making automatic packaging film is an affordable choice.
So how is the automatic packaging film made into a packaging bag?
There is a black rectangular color block around the printing surface of each bag of automatic packaging film, which we call “electric eye position”. When making packaging bags, our automatic packaging machine mainly distinguishes each bag according to the electric eye position. The automatic packaging machine will wrap the food and make it into food packaging bags. In this way, the process of filling products is reduced. Especially for powdery, granular, colloidal and other products, it is much more convenient to use automatic packaging film than packaging bags.
Let’s understand the process of packaging bags again, which is helpful to distinguish the difference between automatic packaging film and packaging bags!
- First, plate making. In the early stage, it is necessary to confirm the source file and bag size, and then plate on the copper plate.
- Printing. After the copper plate is carved, the machine is ready for printing.
- The purpose of aging is to dilute the harmful substances and reduce the residue and odor, such as the smell of glue and ink.
- Splitting, when we print, we usually print several bags on the same film, making use of materials to the limit and saving costs., The purpose of slitting is to separate these printed bags. If they are made into automatic packaging film, they can be directly rolled with roller paper.
- Bag making: make the printing film into the desired bag type, such as three-side sealing, four-side sealing, eight-side sealing, etc.
I believe that after reading the above packaging bag production process, I have an understanding of automatic packaging film,
