Synthetic resin
Bag making machine (4 sheets) The most important component of synthetic resin plastics, its content in plastics is generally 40% to 100%. Because of the high content and the nature of the resin often determines the nature of the plastic, resin is often considered synonymous with plastic. For example, a mixture of polyvinyl chloride resin and polyvinyl chloride plastic, phenolic resin and phenolic plastic. In fact, resin and plastic are two different concepts. An externally processed raw polymer of resin that is used not only in the manufacture of plastics, but also as a raw material for coatings, adhesives, and synthetic fibers. In addition to plastics containing a minimum of 100% resin, most plastics require the addition of other substances in addition to the main component resins.
2. Filler
Fillers, also known as fillers, increase the strength and heat resistance of plastics and reduce costs. For example, the addition of rice flour to phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheapest plastics, while also significantly improving mechanical strength. Fillers can be divided into organic fillers and inorganic fillers, such as wood powder, broken steps, paper and various fabric fibers, such as glass fiber, diatomaceous earth, asbestos, carbon black and so on.
3. Plasticizer
Plasticizers increase the plasticity and softness of plastics, reduce brittleness, and make plastics easy to process. Plasticizers are generally miscible, non-toxic, odorless, high-boiling organic compounds that are stable to light and heat, most commonly phthalates. For example, when producing polyvinyl chloride plastic, if you add more plasticizer, you can get soft PVC plastic. If you don't add or add plasticizer (<10%), you can get rigid PVC plastic. .
4. Stabilizer
In order to prevent the synthetic resin from being decomposed and destroyed by light and heat during processing and use, and prolonging the service life, a stabilizer is added to the plastic. Commonly used are stearic acid eye, epoxy resin and the like.
5. Colorant
Colorants give plastics a variety of bright, beautiful colors. Common organic dyes and inorganic pigments are used as colorants.
Lubricant
The action of the lubricant prevents the plastic from sticking to the metal mold during molding, and at the same time makes the surface of the plastic smooth and beautiful. Common lubricants are stearic acid and its calcium and magnesium salts.

        Following the rapid development of modern society, the state is still very concerned about the environmental protection, and many environmental laws and regulations have been published. About plastic bags is increasing the intensity to manage. More and more people use paper bags instead of plastic bags, and then the paper bag machine will bulge. Today, let us briefly talk about the great use of the single-sheet portable paper bag machine.
        Paper bags are usually made of white cardboard, white paper, copper paper, kraft paper, and a few special papers. They are different according to the side of the bag, the bottom and the back cover. There are open bottom bags, open-bonded bottom bags, and valve type. Four paper bag types, such as a stitching bag and a valve-type flat hexagon end-end adhesive bag. Due to the opening style elements, the name of the paper bag is presented, and some paper bags are hand-held.
        Use four or more layers of kraft paper to pack bags of cement, fertilizer and other commodities. Depending on the function of the packaged object, a different paper bag type is used. Other paper bags: including archive paper, envelopes, handbags, cement bags, feed bags, wax paper bags, fertilizer bags, laminated paper bags, four-layer paper bags, medicine bags, clothing bags, food bags, shopping bags, gift bags, wine bags . Different uses, the standard size of the plan, including the thickness of the paper bag paper, has many requests, so it is necessary to customize according to the actual situation, to get twice the result with half the effort, the economical intention, to save material, green environmental protection, corporate capital investment, supply More guarantees.

        To see that we often use mechanical packaging is much faster than manual packaging, we can see that there are many requirements on our packaging, give you an example such as candy packaging, in the traditional handmade sugar 1 Minutes can only be a dozen pieces, but to see it is up to hundreds or even thousands of pieces per minute in the candy packaging machine, increasing efficiency by dozens of times.
        Secondly, the paper bag machine can effectively guarantee the quality of the package.
        In this use, we must see that the mechanical packaging of the paper bag machine can be based on the requirements of the packaged goods, so it is necessary to see that in this use, it is necessary to obtain the package with the same specifications according to the required size, and this can be seen above. When it comes, manual packaging is not guaranteed. Secondly, it is especially important to export goods. Only mechanical packaging. At this time, we suggest that everyone can achieve the standardization of packaging. Secondly, the product standard meets the requirements of collective packaging.
        Finally, the paper bag machine can achieve the operation that cannot be achieved by manual packaging.
        We will see that there are some packaging operations, because it makes us more convenient. At this time, it is necessary to see vacuum packaging, air-filled packaging, body packaging, isostatic filling, etc. These are all impossible to achieve by hand packaging, and can only be realized by paper bag packaging.

        The paper bag machine is a bag made of paper, so it is very environmentally friendly, and the pollution to the environment should be neglected, and it can be recycled. Nowadays, many kinds of various kinds of bags appear in our lives. The main reason is that the cost is not high, and it is more convenient to take materials.
        Depending on the packaged item, the package should have resistance to moisture, water vapor, gas, light and heat, and also have a certain impact strength, vibration strength and package moisture, etc., and must have on the packaged items. A certain degree of protection. For example, foods must prevent decay and mildew. Drinks should be prevented from spilling and so on.
        At the same time, when selecting materials, it should be non-toxic and non-polluting. Of course, non-toxic is basically difficult, but it should be minimized. However, the bags made by the paper bag machine are made of paper and can satisfy one condition. The packaged material can be produced on a large scale. This is the most necessary. Especially the printing industry. The demand is large. The paper bag produced by the ribbon machine is easy to use.
        The above requirements enable the production of paper bag machines to be continuously applied to different areas of society.

         Why is the paper bag environmentally friendly?
         One is a paper bag that can be used repeatedly with natural materials, and the other is that it does not leave solid waste in the natural environment after being discarded, and does not cause "white pollution." After the general plastic bag is damaged, it is thrown away and it is difficult to decompose. Even if a small part is decomposed, it will produce certain harmful substances.
        The material of the environmental protection bag can be naturally decomposed, and the degradation time is not long, and it can be repeatedly used repeatedly without causing environmental pollution. Although plastic shopping bags are convenient to use in life, but the large amount of use and recycling are not in place, the pollution is very serious, and it also causes a certain amount of energy waste. I think those ultra-thin plastic bags, though It is easy to break when used, but it is very difficult to be naturally degraded. It has become the main source of white pollution. It has become a worldwide problem for white pollution.
        At present, although we have restricted the use of plastic shopping bags, some small farmers' markets are still in use, and the use of paper bag machines has produced more environmentally friendly paper bags, making people accustomed to using paper tote bags and contributing to environmental protection. Give a strength.
