Today, the annual growth rate of China's packaging industry ranks first in the traditional industry, but to keep consistent with the international market, we must accelerate the development of packaging technology to make it develop in an economic, efficient, and multifunctional development. direction. This is a good development opportunity for some companies. The carton factory reminds Chinese paper bag machine equipment manufacturers to seize this opportunity.
        The replacement method is to replace local parts, components or key components and key technologies to achieve the purpose of replacing a unit, so that the production capacity, performance, efficiency, model and assembly method of the original packaging machinery or production line. Get updates. In this way, most parts and unit parts can be reused, which not only increases the value of the equipment, but also saves raw materials and labor, and reduces costs.
        This development trend shows that packaging machinery and equipment and production lines are developing in the direction of standardization, serialization, integration, assembly and online. Civil and military high-tech will also increasingly enter the entire field of packaging machinery and equipment. The fierce market competition will undoubtedly accelerate the upgrading and technological transformation of packaging machinery and equipment in all walks of life.
        In today's world, the replacement of packaging machinery and equipment and production lines is far ahead of Japan, and has won a lot of funds in this field. The four little dragons in Southeast Asia also followed in the footsteps of Japan. They have always been unsatisfactory in the manufacturing of packaging machinery and production lines. In the European Community, Italian packaging machinery and production lines are much faster than other member states.
        The comprehensive update of packaging machinery and equipment is a major trend in the development of packaging machinery in China and the world. The main features of the replacement are: a large number of modern high-precision technology, electronic technology, microelectronics technology, edge technology and fuzzy technology for civil and military industries, which accelerates the further improvement of the reliability and safety of packaging machinery and equipment. production line. Automated level of unattended work. Intelligence will enter the entire packaging machinery and production line.
        Packaging machinery and equipment, production line manufacturing groups and multinational companies in many countries in the world are investing huge sums of money and organizing professionals to conduct research and development, and strive to accelerate the mechatronics process of paper bag machinery. The focus of its development research can be summarized as follows:
        1. Develop multi-functional models for packaging, filling, filling and packaging of various substrate bags, which can be used for multi-functional packaging of paper, plastic, aluminum foil, composite materials and other substrates.
         2. Develop models for saving energy (water, electricity, oil, steam, etc.) to save resources (raw materials, auxiliary materials, etc.) and types of waste recycling.
        3. Developed a multi-shaped packaging machine, which can be used for a variety of packaging, such as square, rectangular, round, oval, triangular, pillow-shaped, strip-shaped and odd-shaped packaging.
        4. Develop multi-base paper bag machine, which can be used to process multi-layer paper bags, plastic film bags, aluminum foil composite bags, paper-plastic composite bags.
        5. Develop a model with low energy consumption, large output power, good dynamic stability, low hum and low pollution.
        6. Develop multi-material packaging machine (long paper bag machine, kraft paper bag machine), which can be used for liquid, semi-fluid, viscous, pulp and solid particles, granules, powder, flake, block, strip models such as singularity and singularity Items are multifunctionally packed.

The square paper bag machine is mainly divided into two kinds of roll paper bag machine and sheet paper bag machine according to the paper feeding method. However, the square paper bag machine is also perfect and has problems with failure. Common is sealing. Not strict, let's look at the reason why the bottom paper bag machine is not tightly sealed.
1. Heat sealing time is too long.
2. Heat sealing temperature is too high.
3. Too much pressure.
4. The edge of the top sealer is too sharp or the coating Teflon is damaged.
5. The silicone rubber on the bottom is too hard.
6. After the plastic composite packaging bag is cooled and placed, the heat sealing strength is increased, and it is also easy to become brittle.
7. During compounding and curing, part of the adhesive penetrates into the film. The substrate is affected by the penetration of the adhesive, the toughness (impact resistance) is reduced, and the brittleness is improved.
The above is what I shared for you.
The reason why the square paper bag machine is not sealed is that we need to find a solution because we know why the square paper bag machine is not tightly sealed.

        What's the matter of making paper-plastic composite bag paper bag machine? Paper-plastic composite bag paper bag machine integrated machine can debug multiple standard paper bags, one machine is multi-purpose, multi-function, but the paper bag machine maintenance should be paid attention to during the process: maintenance rules: all sleeves need to be purchased every 2 hours in the second half Refuel once, after half a month, all casings are refueled every 4 hours.
        1. After each shift, you must ensure that all the stolen goods on the drums on the grape bag machine are cleaned up. In order to make the paper bag machine process smooth.
        2. Tighten the chain every 15 days and maintain proper tightness.
        3. What should I do if the paper bag machine is not completely sealed?
        Generally speaking, LDPE has moderate anti-pollution heat-sealability. EVA has excellent anti-pollution heat-sealability. When the VA content is large, LDPE also has excellent anti-pollution heat-sealability. Excellent anti-pollution and heat-sealability.
        4. Tighten the top of all gears of the paper bag machine every 3 days to prevent loosening.
        5. What should I do if the paper bag machine is crisp and crispy?
        Let us first analyze the elements that constitute this problem: 1 may be too much pressure; 2 the heat sealing time is too long; 3, during the compounding and curing process, a part of the adhesive enters the interior of the film. 4 After cooling and placing the composite bag, the heat seal strength increases and there is also a tendency to become brittle.
        6. Tighten all platen fastening screws every 6 days to prevent loosening. The pressure plate is located on the parallel plate of the grape bag machine. Assuming such a problem exists, our solution: 1. According to the heat-sealing characteristics of the inner sealing layer data, select the appropriate processing temperature, pressure and heat-sealing time; 2 Improve the surface condition of the upper heat-sealing knife to make the surface of the sealing machine smooth. Moreover, this is a problem we often encounter in normal production. Of course, we need to pay more attention to the maintenance of equipment to reduce problems in the production process.

        Now we see the rapid development of paper bag machine equipment. Why have paper bag production equipment developed so well in recent years? I think one of the most important reasons is the active market. The huge market demand has led to the demand for paper bag production equipment. Therefore, we will take a look at how the Chinese paper bag machine industry can better adapt to the market demand.
        The positive paper bag market is due to the demand for safer and more environmentally friendly packaging products. The global low-carbon environmental storm has spread to the packaging industry. The concept of low-carbon packaging was proposed. The main contents of low-carbon packaging are light packaging, clean production, green products, energy saving and emission reduction, and paper packaging. Replacing wood with wood instead of wood is the core of low-carbon packaging. The recycling of waste paper can not only reduce the amount of materials used, cut down trees, protect the ecological environment, but also save energy, water and emissions.
         In the fierce market competition, we should spare no effort to increase investment in equipment and technology, play the role of "environmental protection brand", lead the industry development with high-quality environmental protection products, and highlight the development of packaging enterprises. Enterprises do not forget the spirit of social responsibility. Environmental protection issues should be postponed. This represents the voice of most packaging companies. In the long-term practice of enterprise development, they realized that it is necessary to have both economic and social benefits in order to develop enterprises and save energy and resources.
        At present, the domestic market is extremely active. As China's economy continues to grow, the packaging industry will maintain rapid growth and promote the development of manufacturing. Industry experts said that a reasonable division of labor will greatly promote the development of the domestic industry. Faced with such a demand, how can we make better use of our advantages, first of all, we must start from ourselves and improve the technological level of the enterprise.

        What we want to see is that China's food packaging industry has developed very rapidly in recent years, so this way we can far exceed other manufacturing industries. To be able to see it is based on the speculation of relevant experts in the existing market, and we need to be able to adapt to the rapid development of China's food packaging industry in a future period.
        We can see that there are currently more than 100 domestic manufacturers of such machinery, with an annual output of 15 million units. At the same time, the development trend of bag making, filling and sealing packaging machinery is needed. The modular structure of multiple rows of high-speed and high-stability transmission machinery is simple. At the same time, we must see in our adaptive closed-loop control.
        There is also the need to be able to develop the corrugated box machinery industry in China in the past ten years, and we should see that it is necessary to be able to develop product types from corrugated cardboard lines to printing slotting machines, cardboard gluing machines, corner cutters, etc. Multiple varieties and series should also be developed in the future. First, high-speed complete equipment, but also a medium-light corrugated cardboard box complete equipment.
        We should be able to see the existing pulp molding equipment. It can be achieved that the current production scale of paper tableware processing equipment in our country is relatively small, and we should see that the price of processing equipment is relatively high. We must see that in the future, the pulp mold tableware processing machinery should reduce the cost of forming heating molds and improve the heating method. We must also see increased research in areas such as paper bag machines to increase output.
        To be able to take advantage of such a situation, can take advantage of the performance of existing products. The performance of the product has been improved, so that it is better to make the paper bag opportunity meet the market demand.
