What are the advantages and disadvantages of environmental protection bags?

Advantages and disadvantages of various environmental protection bags:

1, non-woven bag: the main material is non-woven. Non-woven fabric is a new type of fiber product that directly uses polymer chips, short fibers or filaments to form a soft, breathable and planar structure through various networking methods and consolidation techniques. Production technology: non-woven bags generally use screen printing technology, which is often called "screen printing", and has always been a common printing technology for many manufacturers. Generally, manual printing is used, so the color control in the process is not easy to control, so many new non-woven printing methods have appeared. Here we introduce several mainstream printing methods on the market at present. However, with the continuous improvement of customers' requirements for product printing exquisiteness and environmental protection, many new non-woven printing methods have emerged. This paper introduces several mainstream printing methods in the market: named after using water-based elastic mucilage as printing medium, it is more common in textile printing, also called printing. When printing, the color paste is mixed with water-based elastic glue. When developing the printing plate, chemical solvent is not needed, and it can be washed directly with water. It is characterized by good coloring power, strong hiding power and fastness, washability and basically no odor. The gravure products processed in this way are usually called laminated non-woven bags. This process is divided into two steps, that is, the traditional gravure printing process is used to print pictures and texts on the film, and then the film printed with patterns is compounded on the non-woven fabric through the laminating process. This process is generally used in non-woven bags printed with large-area color patterns. It is characterized by exquisite printing, full machine production and short production cycle. In addition, the product has excellent waterproof performance, and the durability of the finished product is better than that of non-woven bags produced by other processes. There are two kinds of films to choose from: bright film and matte film, and matte film has matte effect! The disadvantage is that it conflicts with the concept of environmental protection because the film is difficult to degrade. Thermal transfer thermal transfer belongs to special printing in printing! This method requires an intermediate medium, that is, printing pictures and texts on a thermal transfer film or paper, and then heating them with a transfer device to transfer the patterns to a non-woven fabric. The commonly used medium in textile printing is thermal transfer film. Its advantages are: exquisite printing, rich hierarchical versions, comparable to photos. Suitable for small area color image printing. Disadvantages are high price and high printing cost. Advantages Non-woven bag is a green product, durable, beautiful in appearance, good in air permeability, reusable, washable, silk-screened, marked and long in service life. Suitable for any company, any industry as advertising, gifts. Consumers get a beautiful non-woven bag when shopping, and businesses get invisible advertisements, so non-woven fabrics are more and more popular in the market.

2, environmentally friendly paper bags, materials, as long as the material of the bag contains some paper, it can be collectively called paper bags; Production technology: there are many kinds of paper bags, all kinds of materials and all kinds of paper. Paper bags are generally made of white cardboard, whiteboard paper, coated paper, kraft paper and a small amount of special paper. There are four types of paper bags according to the different sealing methods of bag edge, bottom and back: slotted bottom bag, open corner bottom bag, valve seam bag and valve flat hexagonal bottom plastic bag. Because of the opening method, the name portable paper bag appeared. Some paper bags are portable. More than four layers of kraft paper are used to make bags and packaging products, such as cement and fertilizer. According to the performance of packaging, different types of paper bags are used. Advantages: It should be customized according to the actual situation, so as to achieve the goal of getting twice the result with half the effort and being economical and applicable, and provide more guarantee for saving materials, protecting the environment and investing capital in enterprises.
