The development of handbags from transportation tools to information dissemination is relatively popular in China, but China has had the existence of handbags since ancient times: whenever the New Year is over, our ancients will use a variety of flower cloths to put four The corners are tied into a simple tote bag, filled with rich New Year's goods, the main craft features of the paper bag machine to friends and family, congratulations to the new. In normal times, use linen to make a toast and durable linen bag, put on changing clothes and utensils, go to the distance, walk relatives, and work. Even in today's society, there are many traditional, rustic bags, housewifes who wear sweaters, cloth bags for hanging groups, or woven bags for carrying clothes after work. More typical tote bag design.
        The design of the paper bag machine generally requires simple and generous design. The design of the tote bag and the printing process of the tote bag are mainly based on the company's logo and company name, or the company's business philosophy. It should not be too complicated to design and deepen the consumer's company. Or the impression of the product, get a good publicity effect, the printing of the paper bag machine has a great effect on expanding sales, combing the famous brand and stimulating the purchase to enhance the competitiveness. As a premise of designing a printing strategy for handbags, establishing a corporate image is more important and cannot be ignored. As the basis of design, the grasp of formal psychology is very important. From the perspective of visual psychology, people reject the monotonous form and pursue diverse changes. Tote printing should reflect the unique characteristics of the company.
        From paper bag packaging to handbag printing to use, the main technical features of kraft paper bags not only provide convenience for shoppers, but also take the opportunity to re-sell products or brands. The beautifully designed large bag will be fascinating, and even if the handbag is printed with eye-catching trademarks or advertisements, customers will be happy to reuse it. This bag has become one of the most efficient and affordable advertising media available.
        basic requirements.
        Paper for the paper bag machine can be used with 157g and 200g coated paper. If you need to match the heavier package, you can use 300g coated paper or more than 300g paper. If you choose to use coated paper or cardboard, you usually need a film or a film to increase its strength. In addition, white kraft paper is more and more widely used in handbag making because of its toughness and environmental protection. It is usually used with 120g or 140g of white or yellow kraft paper. The main classification of paper bags needs to be oiled after printing to protect the ink from doing. Wipe dirty when the bag.

        Hard plastic packaging
        Hard plastic packaging is loved by consumers and packaging manufacturers.
        Recently, a cleaning company has redesigned the packaging of paper bags. The new design reduces the amount of pure resin used, and has developed a lighter, new press-type spray bottle that is distributed to a number of markets around the world in a certain proportion. This design saves the company 9 million pounds of pure resin per year. At the same time, because the weight of the bottle itself is reduced by 9%, the shipping weight of the same quantity of products is also reduced, saving freight costs. Moreover, in recent years, Canada has about 4 billion containers of general cleaning products per year. If 20% of the packaging is made of recycled materials, the amount of resin saved is very spectacular.
         A reversible, concentrated perfusion cleaning system for a nebulizer. Consumers only need water tanks filled with tap water to use them. The water tanks are equipped with switches, which are very convenient for users to operate. This sprayer and water tank can be reused many times, effectively reducing the amount of waste. Compared to conventional water tanks, it has a plastic content of less than 63%, saves 185.7 to 22.7 ounces of water, and is recycled by most environmental groups.
        Degradable packaging came into being
        In order to control the pollution caused by plastic waste to the ecological environment, degradable plastics came into being and became a hot spot for research and development around the world. In addition, the increasing energy costs also lay the foundation for the emergence of bioplastics in the market. Bioplastic refers to a plastic formed by microorganisms based on natural substances such as starch. It is recyclable and therefore environmentally friendly. Not only that, but its adaptability to the body is also very good, and it is expected to be used for the production of medical products such as postoperative sutures that can be absorbed by the body.
         Bioplastics can be used to reduce the consumption of petroleum in the production of plastics; biodegradable plastics can promote the slow recovery of plastics in the United States; bioplastics do not contain toxic substances such as polyvinyl fluoride and phthalates, and the health effects of these toxins have been Widely concerned, some countries have banned the addition of phthalates in toys and baby products; the development of bioplastics is obtained from pure plants, which contain a lot of starch and protein, which is also acrylic in bioplastics. The main source of polylactic acid, acrylic acid, polylactic acid and the like extracted from plants are produced into biodegradable plastic materials through various processes, which largely avoids environmental pollution and damage, which is impossible for traditional plastics. The superiority of comparison.
        E-commerce is hot, and environmental protection is indispensable
        In order to improve the packaging waste under the e-commerce, various e-commerce companies have explored the recycling of packaging materials and the use of new environmentally friendly materials. According to the National Post Office, in 2013, China’s express delivery volume was 9.2 billion. However, there is a huge environmental risk behind this number. At present, the packaging and filling materials used in Chinese express goods are mostly non-degradable materials such as plastics and foams, which cause irreversible damage to water sources and soil.

Analyze and solve the situation that the sealing of the paper bag machine is not strict
the reason:
(1) The heat sealing temperature is too high;
(2) The pressure is too large;
(3) The heat sealing time is too long;
(4) The edge of the upper sealer is too sharp or the coated Teflon is damaged;
(5) The bottom sealing silicone rubber is too hard;
(6) During the compounding and aging process, a part of the binder penetrates into the inside of the film. The substrate is affected by the penetration of the binder, the toughness (impact resistance) is decreased, and the brittleness is improved;
(7) After the plastic composite packaging bag is cooled and placed, the heat sealing strength is enhanced, and there is also a tendency to become brittle.
Countermeasures:
(1) selecting a suitable processing temperature, pressure and heat sealing time according to the heat sealing property of the material of the inner sealing layer;
(2) improving the surface condition of the upper heat sealing knife to make the surface of the sealing device flat;
(3) Covered with Teflon cloth;
(4) Select a silicone rubber mat of suitable hardness.

       The paper bag machine at the bottom is the key point of the paper bag machine. It is a new type of paper bag machine, which can be used to process some thick paper such as kraft paper and white cardboard. The papermaking efficiency is very high, which is very suitable for office teaching and so on. Industry needs.
       This common bottom-bottomed paper bag machine has many features and features that make it very different from other paper bag machines:
        1. Its discharge is through the method of steaming, using magnetic powder brake and tension control system to control the tension of the paper bag, and the system is automatic.
        2. After the paper is caused, it will go through the relevant processing and cutting work, and output the paper from the inside of the bag.
        3. The printing can be automatically tracked, so that the precision of printing is accurate. This method does not need to change the paper again. If the sudden situation occurs, the position can be automatically adjusted, which can save time and reduce the scrap rate of the villa door emulsifier pump two-wing rotary door emulsifier soda mixer static mixer.
        4. Easy to operate, very well maintained, all automatically adjusted.
        These are some of the performance characteristics of the square bottom paper bag machine. It can be seen that the paper bag machine is very practical. Now the technology is constantly improving, I believe that there will be more breakthroughs in the future.

         China's packaging machinery started late. After more than 20 years of development, China's packaging machinery has become one of the top ten industries in the machinery industry, providing a strong guarantee for the rapid development of China's packaging industry. Some packaging machinery has filled the domestic gap and has been able to basically To meet the needs of the domestic market, some products are also exported. Moreover, China has made great progress since its accession to the WTO. The level of packaging machinery has risen very rapidly, and the gap with the world's advanced level has gradually narrowed. As China becomes more open, China's packaging machinery will further open up the international market. However, at present, the export value of China's packaging machinery is still less than 5% of the total output value, but the import value is almost equal to the total output value, which is far from the developed countries.
        The development of the packaging industry in the future is not limited to the research and development and application of packaging materials itself, but also in the intensive processing. China's packaging industry is still in the downstream of the entire packaging industry chain, with low level packaging technology and sustainable development of the packaging industry in the future. There is also a need to fundamentally adjust the product structure. Luo Baihui, chief analyst of Jinmo Machinery Network, pointed out that in addition to steel belt balers, pneumatic balers and some small automatic balers, semi-automatic balers have certain scale and advantages, other packaging machinery is almost non-systematic and scale, especially Some package production lines with large demand in the market are monopolized by several packaging machinery companies in the world packaging market.
        The domestic packaging industry must accelerate the pace of transformation and upgrading to meet the rapidly growing market demand and increasingly diversified customer requirements.
