After the material is formed, the plastic film is produced from the ton bag through a machine, and the plastic film is cut into filaments. Then heat is used to shape it to make PP raw yarn, which is then woven and laminated to make a ton bag base fabric.
The production of container bags requires sling stitching. This is the entire production process. It seems simple, but you must be careful during production, otherwise it will cause problems in later use. Ton bags greatly improve people's work efficiency and ensure production operations. Ton bags look simple, but their production is not. The design of ton bags must comply with environmental protection regulations and not damage the ecology. At the same time, the cargo volume must be ensured to ensure that items can be securely protected during loading, unloading, storage, and transportation. Therefore, the technical requirements for ton bag manufacturers are relatively strict.
Second-hand ton bags are also very clear, we usually put some flour, feed, and other materials. This is not a problem. This type of bag has a relatively high weight and shows advantages in quality and density. Some unused items are inside, and the rest may be damaged. Compared with new ton bags, use second-hand bags. It is relatively low, generally neat and clean when processed and customized, and the quality is good. The tonnage of bag-making material is made of polypropylene. I heard that PP is a crystalline polymer. The suitable PP in plastic is 0.91g/Cm3 (less than water). In general plastics, the temperature of PP is 80-100°C and can be boiled in boiling water. PP has excellent stress crack resistance and high flexural fatigue life. It is better than PE material. PP products are light in weight, have good toughness, and good chemical properties. The disadvantages of PP are: low dimensional accuracy and lack of rigidity. Weather resistance It is aging, brittle, and easy to deform. PPR (pentatricopeptide repeats), also known as random copolymer polypropylene (PPR), has high processability and creep resistance when drinking. It has outstanding properties and has the common advantages of random copolymerized polypropylene. It can be widely used in the production of packaging materials, household appliance parts, and various films.
