The first type of paper bag machine is the fixed-length sealing and cutting of paper bags. This positioning system is a fixed-length positioning system. It only requires the speed of the sealing and cutting movement to match the bag delivery speed to reach the fixed-length sealing and cutting request; the other is the printing bag positioning system, printing the bag The positioning system is the tracking of positioning, and the position of each request for sealing and cutting must fall at the designated identification position.
When carrying out various sealing and cutting missions, we will inevitably encounter a problem; that is, the bag length requested by each mission may be changed, and this will inevitably affect the initial value of the bag length preset in the system.
And because the interval S between the photoelectric eye for checking the paper bag identification and the sealing and cutting is a fixed value, the bag length is changed, which will inevitably affect the relationship between the bag feeding speed and the sealing and cutting speed. Therefore, in order to realize the automatic positioning of processing, it is necessary to make a certain function adjustment between the bag length and the interval S. But this is only useful for sealing and cutting printed bags, and has no meaning when sealing and cutting paper bags.
In the packaging and production industry, composite thin bags used as packaging bags can be divided into two types: one is paper bags and the other is printed bags (color bags). The color bag is printed with other identifications for photoelectric signal inspection sensor.
The active positioning system of the sealing and cutting machine actively detects the frequency of the sealing and cutting machine controlled by the main motor through a photoelectric signal sensor, and then converts the number of pulses to compare with the number of pulses checked by another photoelectric signal sensor, and adjusts the frequency of the feeding stepping motor to achieve the change The feeding speed makes it adapt to the sealing and cutting movement of the main motor.

The raw material of paper bags is of course paper. Modern papermaking may come from trees, or it may be recycled paper products after recycling waste paper products. If pure pulp is used, of course trees need to be harvested. This environmental impact requirement is added to the paper bag and it is not so white. If recycled paper is used, the crime of cutting trees is of course less, but in the process of waste paper recycling, cleaning, deinking, and repulping, a lot of dust and sewage will actually be generated, and the demand will cost more. Energy. In addition, because recycled paper has a shorter fiber, its load-bearing ability is slightly worse. The domestic use of it to make paper bags is still less contrasted, and more are still made into printing paper. In other words, most of the paper bags you use may still be made of pure pulp.
The portable paper bag has the functions of carrying and storing. Nowadays, it is widely used in commodity packaging in clothing, food, footwear, gifts, tobacco and alcohol, and medicines. It is also one of the prefaces of the best visual flow to convey the company's image. It has a relatively high level and quality, so the production requirements are high.
Today, the printing expert informs you that you should do this when printing tote bags.
1. Commonly used paper for handbag printing
1. Most of the papers used for handbag printing are 157g/㎡, 200g/㎡ coated paper, in addition, 120g/㎡, 140g/㎡ white or yellow kraft paper is also compared.
If the handbag needs to be loaded with heavier goods, there are also 300g/㎡ coated paper or 300g/㎡ or more cardboard. If you want to further strengthen the strength of the handbag, you can cover it according to your needs, contact the planning of the handbag, and cover it with a layer of bright or matte film to show the exquisiteness of the handbag.
2. White kraft paper has strong toughness and environmental protection. Recently, it has been increasingly used in the printing and manufacturing of handbags.
3. The color expressiveness of the coated paper is relatively strong, so the planning style of the handbag can also be unique. In terms of printing technology, all the technologies in modern printing can be expressed on a small handbag.    
2. Paper bag planning   
When planning handbags, the primary focus may be on how to make handbags special in planning and exquisite printing, which can leave a deep image. Nowadays, features such as being able to be used repeatedly and having environmental protection features are also among the main points considered by planners.
Corporate handbag planning usually requires concise and generous. The front of the handbag planning and printing process is usually based on the company’s logo and company name. Perhaps the company’s operating philosophy should be added. The planning should not be too cluttered, which can deepen consumers’ understanding of the company or products. To obtain a good publicity effect, the planning and printing of handbags has a great effect on expanding sales, establishing famous brands, and influencing purchasers to enhance competitiveness.
Three, paper bag scale
Many commodity handbags are only arbitrarily manufactured based on the scale of their commodities. Usually many commodities are produced and processed without considering the scale of the handbag when it is packaged, so it cannot be prevented from being printed in the handbag. It will be spoiled.
When planning bags for customers, printing factories should be as close to their standards as possible, and they should also try to prevent their unnecessary waste.
For example:
The scale of the direct facing: 400*300*80 (mm), this scale is not spoiled, a full-open paper can be made into two bags, and the printing is also cost-effective, and it can be printed with a facing machine. If If the customer wants to make the scale of 400*320*100 (mm), this is a large scale, and it is not spoiled, but if it is made to 400*300*150 (mm), it will not work. The spoilage is relatively large. First, there is spoiled on the paper, and secondly, there is spoiled on the printing. In addition, the post-processing costs are also higher, because the handbags of this size can only be made into double sticky mouth.
Fourth, paper bag forming
By laminating the film after printing, and then punching and threading (usually nylon rope or cotton rope, some thin paper bags often use paper rope), the handbag can be formed (such as the large printing scale of the handbag, the rope hole Reinforce the rivets to resist tension).
It can be seen that the production technology of handbags is not messy, and the process of just stringing usually requires manpower to complete. Therefore, compared with other printed products, the technical process is slightly messy, which also increases the cost of handbags.

We must see that what we often use is that mechanical packaging is much faster than manual packaging. We must see that our packaging also has many requirements. Let me give you an example such as candy packaging. In traditional manual sugar packaging 1 It can only pack a dozen yuan per minute, but you can see that it can reach hundreds or even thousands of yuan per minute in the candy packaging machine, which increases the efficiency by dozens of times.
Secondly, the paper bag machine can effectively ensure the quality of packaging
In this use, we have to see that the paper bag machine can be mechanically packaged according to the requirements of the packaged items. So we should see that in this use, you can obtain packaging with consistent specifications according to the required shape and size, and you can see it. When it arrives, manual packaging is not guaranteed. Secondly, this is particularly important for export commodities. Only mechanical packaging. At this time, we suggest that everyone can achieve packaging standardization, followed by product standardization, which meets the requirements of collective packaging.
Finally, the paper bag machine can achieve operations that cannot be achieved by manual packaging
We will see that there are some packaging operations, because it makes it more convenient for us to use. At this time, it is necessary to see that vacuum packaging, inflatable packaging, skin packaging, isobaric filling, etc., which cannot be achieved by manual packaging, can only be achieved with paper bag machine packaging.
