You don't know the suction nozzle of self-supporting bag hidden secret!

In recent years, with the continuous development of plastic packaging, more and more food companies begin to take suction nozzle self-supporting bag as product packaging. Suction nozzle self-supporting bag manufacturers understand this is because the packaging is easy to open, can be repeated the advantages of sealing and packing materials consumption, high-level printing decoration, packaging, warehousing, transportation cost is low, solve the advantages of small volume, referred to as environmentally friendly packaging, popular throughout the country. Suction nozzle self-supporting bag sealing performance and cap torque directly affect the shelf life of product and product application adaptability. Sealing performance is refers to the suction nozzle self-reliance mouth sealing reliability, through the test can ensure sealing and integrity, prevent leakage caused because of poor sealing performance, pollution, degradation and other issues. Seal performance test have a variety of methods, commonly used method is to use leakage test instrument, seal tester is generally use vacuum principle, respectively - according to the national standards 30 kpa, 50 kpa, 70 kpa, - Keep 0 90 kpa. 5 minutes. For vacuum packaging is recycled experimental samples. Method is to adopt the principle of visual method, of course, is a method of qualitative inspection for quantitative detection of suction nozzle sealing and leakage performance of self-supporting bag packing, sealing performance test equipment can take positive pressure method. Bottle packaging is a common form of food and beverage packaging. Packaging bottle caps lock and unlock the torque size is production device control one of the technical parameters of offline or online. The torque value is suitable for the transportation of products, and consumption has a great influence. Is one of the key products of corporate control. Suction nozzle self-supporting bag bottle caps lock and the size of the open torque value is one of the production line or online keying technology parameters. Torque values can be suitable for the suction nozzle bag products in the middle of the transport and consumption has great influence.
