As nut food is hard, the thickness of food packaging bag and the strength of material impact resistance will affect the use effect of packaging; some nut food packaging bag is packed with inert gas, so the sealing property is also very important. The following is an analysis of the testing methods for the sealing and impact resistance of the packaging bag:
1、 For the detection of heat sealing: the sealing strength of the heat sealing parts is verified by the heat sealing strength test. If the heat sealing strength is not proper, the problems such as air leakage and bag breakage will occur.
2、 In view of the sealing test, through the sealing energy (negative pressure method) test, we can find the parts of the finished product packaging that are prone to air leakage and pressure relief.
3、 Aiming at the detection of the impact resistance of the contents, the burst pressure (positive pressure method) test was carried out to verify whether the packaging was filled with gas to test whether the bag was broken under the impact of the internal gas, which was used to find the position where the packaging of nut products was easy to crack and the compressive strength.
4、 According to the analysis of the gas composition in the packaging, through the headspace residual oxygen and carbon dioxide performance test to verify, the proportion of oxygen, carbon dioxide, nitrogen in the finished product packaging can be monitored, so as to determine the sealing performance of the finished product packaging, and the gas proportion inside the packaging meets the quality requirements of nut products.
5、 For the detection of the drop resistance performance, the relevant drop resistance test is provided to further verify whether the package is broken when the package falls within a certain height.
