FIBCs are as useful a product as possible without coating or plating. In today's packaging design of container bags, it is necessary to make the packaging feel more beautiful and more corrosion-resistant and use electroplated materials. This not only brings about the problem of mass recycling and material reuse of obsolete products. Secondly, most paints themselves are toxic. If everyone eats these packaged foods, it will cause great harm to everyone. The second coating and electroplating process also brings great pollution to the working environment. For example, coatings evaporate toxic solvent gases and produce waste liquids and waste residues including heavy metals, such as during electroplating. Therefore, packaging materials that are uncoated or plated should be selected as much as possible. The above is a detailed introduction to what you should pay attention to when purchasing a fork bag. When purchasing plastic packaging bags for food, everyone can refer to suitable fork-ton bags.
The quality of container bags directly affects the company's subsequent market development, so it is essential to conduct certain quality inspections before the products leave the factory.
There are two effective quality inspections used before container bags leave the factory.
One is a stress test. Put the fully loaded container bag on a pressurizing machine for a pressure test. The pressure applied by the press is four times the full load weight of the container bag. You may use the static load method, that is, the self-weight of the four-layer fully loaded bag. The pressurizing time is For more than eight hours, if the contents do not spill out and the bag body is not damaged during this test, it means that the container bag has passed this test.
The second type is the drop test. Lift the fully loaded container bag with lifting equipment. The bottom of the bag should be more than 0.8m above the ground, and then drop vertically to a solid and flat ground. If the contents do not spill out and the container bag body is not damaged, it means After this test.
Supervised and controlled the ton bag material purchasing warehouse Material purchasing and packaging product warehouses must prevent fireworks, have fire safety, heat insulation, waterproofing, good lighting and natural ventilation, and keep clean, orderly, and dry. The purchase of materials and storage of packaging products must comply with their characteristics and regulations. The source of raw materials must be clear, must be inspected when entering the warehouse, and must be well marked. Records must be established of the names, manufacturers, quality specifications and models, factory entry time, and quantity of various raw materials such as ton bags and other products to ensure that the accounts are consistent. The storage of raw materials must be fly-proof and mildew-free and must be delivered according to the first-in-first-out method. Supervision and control of production workshops such as ton bags. The natural environment of the production workshop must comply with product standards and regulations. Fireworks, high-temperature protection, waterproofing, lighting, and natural ventilation must be excellent and must be kept clean and orderly. The stacking must meet certain safety standards, and the stacking height must be high. The width ratio cannot exceed 2m.
