According to the aluminum spout pouch manufacturer, this is because the packaging is easy to open, can be sealed repeatedly, and the consumption of packaging materials is low, high-level printing decoration, packaging, warehousing, and transportation costs are low, and the advantages of solving small volume are called Environmentally friendly packaging.
With the continuous development of packaging, more and more food companies have begun to adopt aluminum spout pouch as product packaging. According to the aluminum spout pouch manufacturer, this is because the packaging is easy to open, can be sealed repeatedly, and the consumption of packaging materials is low, high-level printing decoration, packaging, warehousing, and transportation costs are low, and the advantages of solving small volume are called Environmentally friendly packaging. The sealing performance of the nozzle bag and the torque of the bottle cap directly affect the shelf life of the product and the application adaptability of the product.
The sealing performance refers to the reliability of the sealing of the mouth of the aluminum spout pouch. Through the test, the sealing performance and integrity of the product can be guaranteed, and problems such as leakage, pollution and deterioration caused by the poor sealing performance of the product can be prevented. There are many ways to test the sealing performance. The most common method is to use the sealing tester. The sealing tester generally uses the vacuum principle, and keeps it at -30kPa, -50kPa, -70kPa, -90kPa for 0.5 minutes according to the standard. For vacuum packaging, mainly recovered experimental samples. Of course, the method is based on the principle of the visual method, which is a qualitative inspection method. If you want to quantitatively detect the sealing and leakage performance of the nozzle self-supporting bag filler, you can use the positive pressure method sealing performance test equipment.
