Precautions for use of paper bags
Other factors that affect the stability of container bag stacking, such as the flow characteristics of loaded materials, the empty space in the bag and the air trapped in the bag. The stacking stability of container bags can be improved by shaking the container bags during loading and squeezing the trapped air after loading. When loading and unloading with a forklift, the pallet at the bottom of the goods shall not be unloaded by the forklift foot, and the two lifting lugs at the top of the goods shall not be dragged out. If there is no pallet, try to unload the cargo with 4 lifting lugs. Prevent the packaging bag from being damaged due to uneven force on the goods. The container bag is usually unloaded by gravity, but sometimes the suction pipe is also used for unloading. When gravity is used for unloading, the unloading speed can be controlled by adjusting the size of the unloading port. The disposable container bag can be unloaded by simply cutting the bottom of the bag. A cutting knife with a handle of appropriate length is required to cut the bottom of the disposable container bag. The container bag with discharge port shall be hung safely before the operator unties the lanyard at the discharge port. The operator must not stand under the container bag. During loading and unloading, appropriate dust control measures shall also be taken to avoid flying of loaded materials. In case of electrostatic hazard, corresponding measures shall be taken.
Functions and Differences of Flexible Container Bag Film
Flexible container bags are woven from polypropylene flat wires. Because of this braided structure, very small raw materials may leak out from the weaving gap or sewing line pores, such as fine sand, fine powder and other products. If you use non coated container bags to pack powder products, when you knock one side of the container bag, you will see dust cloud like products leaking out of the container bag. Although in some scenarios, it doesn't matter; However, in other scenarios, this is not allowed. The structure of coated container bag is the same as that of non coated container bag. However, before the bag is sewn into shape, an additional layer of polypropylene film will be coated on the sheet cloth to seal the flat yarn weaving gap. The coating film is common in the bag, because it can prevent the powder products from being embedded in the woven flat wire when discharging.
Classification knowledge of various container bags
Classification knowledge of various container bags: Supplements generally refer to nutrients such as vitamins, amino acids and minerals. Most of their raw materials are in the form of granules and powders, so the entire production and transportation process needs to meet the standards of food/drug grade. Container bags are generally used for bulk transportation of supplements and raw materials, and three points should be noted for such container bags. 1. Leakproofness Generally, when sewing the container bags, the pieces of cloth will pierce holes, and fine powder may leak out from the holes or weaving gaps. The leakproof container bag shall be specially designed according to the transported goods, and the leakproof strip, non-woven fabric or double-layer bag body shall be adopted according to the flow coefficient of goods (the greater the leakage is, the easier the leakage is).
Non negligible points in the production process of woven bags
The production process of woven bag manufacturers is also a process of constantly solving problems. For woven bags, it is important to eliminate static electricity generated in the production process. In fact, this problem can be easily solved by professional woven bag manufacturers. We already know that in the production process of woven bags, many processes can eliminate static electricity, from the purchase of raw materials to the delivery of woven bags. One of the easy to operate procedures is in the process of wire drawing, as long as the use of static elimination equipment or a piece of wet cloth can be very simple to eliminate.
Have you been hit by the notice of plastic woven bag covering?
1. Align with the middle of the rubber roller as much as possible before rolling the cloth. 2. Before the roll of woven bag is fed into the vehicle, both ends of the silicone rubber roller shall be coated with silicone oil. 3. The synchronous speed is reduced to less than 30 m/min when receiving and unloading cloth. 4. Clamp the roll before receiving the cloth, and don't forget to stick the tape. After receiving the cloth, keep the cloth edge aligned with the polarization correction photoeye and then lift the pinch roll. 5. When connecting new cloth, the width of the cloth varies, so it is necessary to observe the cloth edge and adjust the mold edge. 6. The vehicle speed is slightly slow before receiving cloth; After receiving the cloth and before the double-layer joint enters the corona, turn off the corona machine first. 7. After the double-layer joint enters the compound roll, lift the edge cutter and turn on the hair dryer. After the joint, cut and trim the edges. 8. When the joint is rolled, change the roll in time.
Focus on the research and development, production and sales of high-standard industrial packaging bags such as container bags and paper bags
