Technical Data

User Purchase and Usage Evaluation

Zhejiang Hangzhou - Food Packaging Factory - Mr. Liu

We mainly produce corrugated paper bags for baking and snacks. This Roll-fed Flat Bottom Paper Bag Machine was the one we finally chose after comparing several options. The old machine we used often got paper jams and was troublesome to adjust the size, and the workers were reluctant to handle it. After replacing it with this machine, we used it for over a year and basically had no major problems. The touchscreen operation of Schneider is very convenient. The workers learned it in a short time and could operate it easily. Changing the size was done directly by inputting parameters on the panel, saving a lot of debugging time. Making oil-proof paper bags did not slip, and the edge bonding was very strong. Customers reported that the bags did not leak oil.

Guangdong Dongguan - Dry Fruit E-commerce Packaging Supplier - Mr. Chen

We make packaging bags for nuts and dried fruits, and the requirements are quite high, especially the need for a transparent window to facilitate product display. This machine just supports the installation of the window device, and we selected this configuration. The window is flat and not bulging, and the hot melt glue does not overflow. It is much more convenient than finding an external processor. Moreover, it can directly recognize the position of the printed bag and cut the pattern precisely, reducing the defect rate significantly compared to before.

Jiangsu Suzhou - Environmental Protection Paper Bag Contract Manufacturer - Mr. Wang

The stability of this machine exceeded expectations. We often rush orders, and the machine rarely had malfunctions even after running for several consecutive days. We used the British TRIO servo and the German SICK optical sensor. The positioning was extremely accurate, and the cutting error of the printed bags was very small. Compared to the previous machine, the efficiency was directly doubled, and it saved two workers. As a result, the return on investment was much faster than expected.

FAQ

Q1: What types of paper can this Roll-fed Flat Bottom Paper Bag Machine process?

A: It has excellent compatibility with various types of paper, including ordinary kraft paper, textured kraft paper, oil-resistant paper, laminated paper, medical-grade paper, etc. It can stabilize the feeding, shaping and bonding of different weights of raw materials, and meet the bag-making needs of various industries such as food and medicine.

Q2: Can the printed paper bags with patterns be precisely cut?

A: Yes. The equipment is equipped with German SICK photoelectric deviation correction and British TRIO servo control system, which can track the printed marks in real time, ensuring the cutting position and pattern alignment. Even for continuous printed rolls of paper, it can achieve extremely small errors and high product consistency.

Q3: Will the operation become more complicated after installing the window device?

A: No. The control of the window device and the main unit are integrated on the same operation interface. Parameters can be set together, and during production, the coating, glue spraying and window lamination are automatically completed without additional manual operations. Moreover, the thermal glue system is precisely controlled, and there will be no problems of glue overflow or bubbles, and the finished products are very regular.

Q4: Does the version with the printing unit have high requirements for the site and operation?

A: Different from traditional printing machines, this optional printing unit does not require additional reel storage space and can complete printing directly in the bag-making process. This saves a lot of space. The operation is also controlled in conjunction with the main unit, and workers do not need to learn the operation of the printing machine separately. They can get up and running quickly.

Q5: How stable is the Roll-fed Flat Bottom Paper Bag Machine when running continuously for a long time?

A: It adopts TRIO's microcomputer control system and is equipped with optical fiber signal transmission. The running speed is stable, and it is less likely to experience stalling or deviation. Many customers operate it for several consecutive days during peak orders, with a very low failure rate. As long as the basic maintenance is done according to the manual, production will not be affected.
