    Called shopping bags
    The shopping bag, as the name suggests, is a bag used for shopping. At present, the shopping bags available on the market are mainly: plastic shopping bags, non -woven shopping bags, paper shopping bags, cotton and linen shopping bags, etc. Essence

    The material classification
    Plastic
    Plastic shopping bags are packaged materials made of polyolefins as the main raw materials and appropriately added other substances. The adopted polyolefins are mainly polyethylene (PE), commonly known as soft glue. The main products include low -density polyethylene or high -voltage polyethylene (LDPE), high -density polyethylene or low -voltage polyethylene (HDPE), linear low -density polyethylene ( LLDPE) and Mammami Polyvinpe (MLLDPE). In order to reduce its cost, most companies add about 30%of calcium carbonate to make a filling plastic shopping bag. Such plastic shopping bags do not release toxic gases when burning in the dump. The National Plastic Shopping Bag Standard just introduced divided the plastic shopping bags into three categories:
    ordinary plastic shopping bags -using polyolefins and fillers as raw materials. Such plastic shopping bags do not have degradation performance, and it is not abandoned in the wild. Will not degrade. Such plastic shopping bags have excellent recyclables and can be reused multiple times. The performance of the recycling material is slightly reduced to varying degrees, but it can be used for shopping bags or garbage bags with low production performance requirements and poor color requirements. The key question is whether it can be recycled.
    Serbile plastic shopping bags -such shopping bags use modified starch as the main raw materials, and appropriately add a small amount of degradable materials to improve its performance. The plastic shopping bag is abandoned in the wild after use.
    The degradation plastic shopping bag -such shopping bags can be produced as raw materials that can completely degrade plastic and have fully degradable performance. Product abandonment can be completely degraded into small molecular microorganisms without any environmental pollution. Such plastic shopping bags are promoted abroad. According to the specific composition of fully degraded plastics, it can be divided into three categories as follows:
    (1) PLA and PHA biodegradable plastics synthesized by natural starch as raw materials through biological fermentation methods require a lot of food Therefore, development space is limited.
    (2) The fatty polycarbonate (APC) category with carbon dioxide as the raw material degrades plastic. It uses the industrial by -product carbon dioxide that is shouted by everyone as the raw material. The amount of emissions eliminates the global warming phenomenon caused by greenhouse gases, and it is obtained in one stone, so the market prospects are broad.
    (3) The complete degradation product of non -starch degradation is added to ordinary plastic. It is in the industrialization stage. For example, the degradation performance is reliable and very promising.
    non -woven fabric
    non -woven shopping bags are non -woven fabrics made of plastic. Many people think that it is a natural material, which is actually a misunderstanding. Commonly used non -woven raw materials are polypropylene (English abbreviations PP, commonly known as patelion) or polyzed phenyl acetate (commonly known as PET, commonly known as polyester), especially PP and plastic shopping bags. The five major plastic varieties are plastic varieties that cannot be degraded in 50 years. For example, we all call ordinary non -woven shopping bags that are environmentally friendly shopping bags, which are made of polypropylene fiber through special processes. In essence, polypropylene (PP) is a typical variety of plastic. Like ordinary plastic shopping bags, it cannot be completely degraded.
    In specific cost -effectiveness, the strength of non -woven bags under the same conditions is not as good as plastic bags, and it is not waterproof, and its price is several times higher than that of plastic bags. It should be mentioned that the difficulty of recycling and reuse is greater than ordinary plastic shopping bags for non -woven shopping bags made of more than two materials.
    paper category
    everyone knows that the strength and water resistance of paper are not good. Many water -based products such as seafood cannot be packed, and heavier metal products are difficult to support. First of all, the raw materials for making paper are mainly wood, and the world's forest resources are extremely scarce. This is the greatest waste of environmental resources. Secondly, the process of making paper will produce a lot of water pollution. Cross -paper factories across the country are beaten everywhere. Therefore, a large amount of paper bags are the greatest waste of environmental resources and the greatest pollution to the environment.
    cotton and linen
    The strength of cotton and linen shopping bags is better than paper bags and can be used multiple times, but water resistance is not good. The advantages of cotton and linen shopping bags are recyclable, but what should I do if the cloth bag is dirty? Washing with water is the most commonly used method, but washing water wasted water resources, and phosphorus -containing laundry powder would contaminate the soil. At the same time, ordinary water washing cannot eliminate bacteria.

    The waste paper
    1. For general dry goods, it is recommended to use the nation's waste or European waste, and control the production of the original paper according to the technical indicators of the A or B or B -class cowhide box paper. The surface layer can hang noodles or noodles. This should be based on whether to print complex patterns and advertisements. The quantity of the paper pages can bear the weight of 8-15 kg at 135 ~ 150 grams /m2.
    2. For goods that need to bear a certain amount of moisture, you can also use full waste paper. But on the basis of the above standards, add a certain amount of wet strong agent 0.5 ~ 1.0%, and the dry strength of the wet strength of 10-15%.
    3, for meat or other wet goods, you can also use all waste paper to make shopping bags. This requires an environmentally friendly oil -proof agent to add or surface to the slurry in the process of papermaking. You can also spray water -soluble or degradable resin on the surface with good surface strength.
    4. Many manufacturers in Mainland China have developed full -scrapped paper clips. That is to say, when the paper is copied, the two layers of pulp bind to the textile principle to add water -soluble yarns. The one layer of this kind of paper can achieve the strength of the four layers of cowhide paper, which can completely replace ordinary cement bag paper. Similarly, a single -layer paper can be used on the shopping bag.
    5, these products are safe and environmentally friendly.

    The design classification
    1, advertising shopping bags
    The shopping bag advertisement can use the limited area of ​​the bag body to spread the market information of enterprises or product services to the world. When customers carry shopping bags printed with store advertisements and walk through the streets and alleys, they are actually some exquisite advertising bags, not as they make an excellent advertising signboard, but the cost is relatively low.
    2, knowledge -based shopping bags
    It is to print all kinds of knowledgeable patterns, texts, such as world famous paintings, Chinese calligraphy, etc., and print on shopping bags.

    6. Time -oriented shopping bags
    Min people generally pursue high -level lifestyle, and fashionable commodity leaders' temporary consumption trends. When the "hot" appears in the society, if the store prints the product pattern and publicity information on a beautiful shopping bag, it is undoubtedly an important trick of promotion. When consumers see that a hot spot is sold, they also have "the temptation that cannot be stopped."
    7, environmentally friendly shopping bags
