In the soft packaging processing industry, flat bag is the most widely used and produced basic packaging form, widely used in dry food, aluminum foil packaging, daily chemical powder, industrial samples, electronic accessories and other fields. A lot of packaging manufacturers in the production of thin, color printing, high-precision flat bags, often encounter cloth bag elongation, size deviation, pattern deformation, sealing edge deformation and other problems, these problems seriously affect the quality of finished products and shipping standards. In order to solve these common production problems, the unstretched bag making machine has become the mainstream equipment of choice in the industry. Compared with traditional bagging machine, it has been completely upgraded in feed, tension control and cutting accuracy, and has made a professional equipment suitable for the production of high quality flat bags. This article will give you a quick overview of the core knowledge and practical value of the device.
In a word, the non-tensile flat bag making machine is a high precision bag making equipment specially designed to solve the tensile deformation problem of thin films. Traditional bagging machines rely on mechanical traction to force the film into place. During high-speed operation, the film is subjected to continuous high pressure stretching, especially of film and soft film materials, which leads to uneven packaging bags length and width, loose patterns and elongation and distortion in the same batch printing, resulting in high defect rate rate. The highlight of the non-stretchable bag maker is the constant tension non-stretchable feeding system, which avoids the deformation of the film at the source and makes each bag even, standardized in size and uniform in appearance.
The core working principle of the device is simple and easy to understand: through a servo precision control system combined with independent feeding buffer structure, the film is in uniform, relaxed, stable transport state throughout the process, no forced traction force or instantaneous tension difference. Combining with high-precision photoelectric tracking positioning device, the position of printing marks and film body can be accurately identified, and the height of each heat sealing point and cutting point can be consistent. The device adopts the stable ``molding before cutting"process, uniform and constant temperature sealing position, sealing edge is firm, blade is flat, no burr, finally produces standard flat bag with publishing type stiffness, no deformation, no error.
In practice, the advantages of such equipment are very obvious. Firstly, it has high molding accuracy and zero stretching deformation, especially suitable for color-printed composite film, aluminum foil film, polyethylene film, etc.. The common problems such as drawing, dislocation and deformation of paper sample in printing bag have been solved thoroughly, and the packaging appearance and finished product grade have been greatly improved. Second, the production stability, high yield rate, equipment operation stability, almost no tension fluctuations, batch size error is minimal, greatly reduce waste loss, effectively save raw material costs, and improve production efficiency.
At the same time, the equipment has a wide range of adaptability, can process a variety of common flat bags. Including color printed composite flat bag, pure aluminum foil flat bag, aluminum film flat bag, food preservation flat bag, industrial sample storage bags, daily chemical powder packaging bag. Both lightweight soft film and conventional thick composite film can be produced stably. The finished bag body has no raised edges, tight the edge sealing and no air leakage. It fully meets the high standards of food food sealing light and moisture moisture prevention industrial protection and so usage requirements.
For packaging processing plant, non-stretch flat bag bagging machine also has the advantages of simple operation, versatility, maintenance and so on. The equipment is intelligent, parameter adjustment is intuitive, can quickly switch different sizes and specifications of flat bag production, suitable for small batch customization and large-scale production needs. The stable mechanical structure reduces the frequency of malfunction and maintenance cost. It is suitable for standardized upgrading of small and medium-sized packaging factories, and also for high-precision production line of large factories.
It is easy for many people to confuse the positioning of ordinary bag makers and non-extendable bag makers. Ordinary equipment is suitable for simple packaging bags with low production accuracy and appearance requirements, while stretch models focus on high-end flat bag production with high accuracy, high appearance and high production, and are central to improving product competitiveness. In today's packaging aesthetics and quality requirements of more and more stringent market environment, non-stretching technology has become a color printing packaging, aluminum foil packaging packaging, food packaging production necessary configuration.
In conclusion, the non-stretching bagging machine, with its core advantages of non-stretching, high precision, good stability and wide adaptability, solves many pain points of traditional bagging process. It not only improves the precision and appearance of flat bag forming, but also effectively reduces production losses and improves production efficiency. It is an indispensable basic production equipment in modern soft packaging industry and a key tool for enterprises to achieve standardized, high-quality flat bag production.
