In recent years, with the continuous development of plastic packaging, more and more food enterprises have started to adopt self-supporting mouth bags as product packaging.Independent suction nozzle bag manufacturer to understand this is mainly due to a cap of packing is very convenient to open and can be repeatedly advantages of sealing and packaging material cost less, printing packaging level is high, packaging, warehousing, transportation, low cost and less waste solution etc. Advantage, is known as environmentally friendly packaging, popular in the country.The sealing performance of self-priming bag and the torsion of bottle cap directly affect the shelf life of its products and the application of adaptability, which are the indexes of strict control by the manufacturers.Then the sealing performance of self-sealing suction bag and the torsion of bottle caps are usually tested.
One, seal performance detection
Sealing performance refers to the strong independent suction nozzle bag sealing, can pass the test to ensure the integrity of the entire product packing seal, prevent because of poor sealing performance, and lead to leakage, contamination, deterioration, etc.There are many types of sealing performance test method, the most commonly used method is to use sealing apparatus, generally sealing apparatus, using the vacuum principle, in – 30 kpa, respectively, according to the national standards – 50 kpa, – 70 kpa to 90 kpa lasts for 0.5 minutes, for vacuum packing mainly inspect the recovery of samples after the experiment., of course, the above method is to adopt the principle of visual observation, is a method of qualitative tests for quantitative detection of suction nozzle bag sealing and leakage performance, then you can take positive pressure method principle of sealing performance test equipment.
Second, the bottle cap torsion test
Bottle packing is one of the most commonly used packaging situations in food and beverage.It is one of the process parameters of the production unit offline or online key control.Whether the torque value can be suitable for the transportation and final consumption of the product has a great impact.Is one of the product indexes that the enterprise focuses on control.
It is one of the process parameters of the production unit offline or online key control.Whether the torque value can be suitable for the middle transportation and final consumption of the suction bag products has a great impact.
