At different times, people's requirements for paper bags are different, not to mention that people have started to use paper bags on a large scale. We all know that in this fast-developing society, the technological level of many machinery and equipment has reached a new level, so in order to adapt to the new needs of paper bag machines, our industry is also making greater changes.
        In this case, the paper bag machine will begin to appear in the trend of large-scale, complete set, automation, and there will be equipment with complex transmission and high technical content. China's machinery production must meet the basic needs of the country. With the acceleration of people's daily work rhythm, nutrition and health foods are abundant, and environmental protection awareness is enhanced.
        In the future, there will be many new requirements for food and its packaging. Plastic bags are obviously not the best choice for people, and they need paper bags at this time. Looking at the current and future, we can confirm that paper bags have great advantages in terms of environment, safety and practicality.
        According to the analysis of group technology ideas, the similarities and similarities between the three are more conducive to unified development, each with special differences, and should be selected according to local conditions. After comprehensive comparison, the main features are as follows. The current packaging items are also very rich, these three models are almost all-inclusive (usually except for gas and liquid materials), but the third limitation.
        They are mainly composed of roll-type composite films. In some cases, the second type can be used for internal suction tubes and the third type can be used for internal ribs and other auxiliary components. There are three patterns, such as three-side sealing bag, four-side sealing bag, double bag, vertical bag, brick box, roof box, etc .; the first is the second, and the third is less, usually pillow-shaped bags. Some can be made into cylindrical bags, four sides sealed bags and so on. The package size can be as small as 10 mm wide, and the bag length can be steplessly adjusted within a limited range; the width and length of the last two bags can be steplessly adjusted within a limited range, and the third bag can reach a length of more than half a meter .

         In the future, if we want to establish a diversified, generalized and multifunctional integrated new paper bag mechanical system, we must first focus on solving the major problems of combination and mechatronics. This is undoubtedly an important development direction in the future. Now that our goals are very clear, we need to strengthen them.
