1. What is the plastic suction nozzle of the self-supporting bag
Self-supporting plastic nozzle refers to a flexible packaging bag with a horizontal support structure at the bottom and a suction nozzle at the top or side; its self-supporting structure can stand on its own without relying on any support and regardless of whether the bag is opened or not. The self-supporting bag originated from the French company Thimonier. In 1963, Mr. McLaus Duye, who was the CEO of the French Thimonier company, successfully applied for a self-supporting bag patent. It was widely recognized in the US market in the 1990s and was promoted throughout the scope Prevail.
Second, the advantages of self-supporting plastic nozzles
Stand-up pouch plastic nozzle is a relatively new form of packaging, compared with the common packaging form is the portability; stand-up pouch plastic nozzle can be easily put into a backpack or even a pocket, and can reduce the volume as the content decreases , More convenient to carry. In terms of improving product quality, enhancing shelf visual effects, portability, convenience, freshness and sealability, etc. The self-supporting bag plastic nozzle is made of PET / foil / PET / PE structure laminated, and can also have 2 layers, 3 layers and other specifications materials, depending on the different products packaged, the oxygen barrier can be added as needed to reduce Oxygen permeability rate, extend the shelf life of products.
At present, the soft drink packaging in the market is mainly in the form of PET bottles, composite aluminum paper bags, and cans. Today, with the increasingly obvious homogenization competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The self-supporting plastic suction nozzle combines the fashion of repetitive packaging of PET bottles and composite aluminum paper bags. At the same time, the printing performance is also unmatched by traditional beverage packaging. Due to the basic shape of the self-supporting bag, the display area of the suction bag It is significantly larger than PET bottles, and better than packages such as Tetra Pak pillows that cannot stand. Of course, because the nozzle bag belongs to the category of flexible packaging, it is currently not suitable for the packaging of carbonated beverages, but it is unique in juices, dairy products, health drinks, and jelly foods.
Third, the production process of self-supporting bag plastic nozzle
The self-supporting bag plastic suction nozzle is composed of a suction nozzle and a self-supporting bag, each of which has high requirements for the process. If it is not well-handled, unqualified products will appear, and the bag will rise during use. Problems such as broken bags and leaks. In order to avoid this situation in the production of self-supporting bags, we must pay attention to the punching, bag bottom, bottom heat sealing and other links, especially the joints of the four-layer and two-layer self-supporting bags are prone to breakage. The horizontal sealing knife is If it is not enough, it is necessary to install a heat sealing knife, and partly to strengthen the heat sealing. In addition, self-supporting pouches with spouts are required to have good opening performance. When making bags, the surface static electricity must be removed to avoid adsorption between the pouches, which is not conducive to the pouch sealing machine to take the pouches.
At present, domestic self-supporting bagged nozzles have two methods: manual nozzles and heat-sealed nozzles. The temperature is transferred to the mouth by heat conduction, so that the mouth melts and is welded to the PE sealing layer of the bag.
The finished bags after production must be inspected by a special detector to prevent leakage and damage. At the same time, the physical properties of the self-supporting bag must also be tested by tensile strength and pressure.
The above is a brief introduction about the plastic suction nozzle of the self-supporting bag. Nowadays, green packaging that expands the function of food packaging and reduces the environmental pollution of the packaging has become the development trend of new packaging. It is believed that the packaging of plastic suction nozzles for self-supporting bags will become better along this development trend.
