食品用脱氧剂包装膜防尘、防水、防油性能测试

以食品用脱氧剂包装膜为研究对象,采用显微镜观测法测试其防尘性能,折盒观察法测试其防水、防油性能。优化后测试条件为:防尘测试采用显微镜观察是否有直穿孔;防水性能测试在室温下采用10 mL 0.08%十二烷基苯磺酸钠水溶液;防油性能测试采用5 mL 60℃的橄榄油;以渗漏时间作为防水、防油性能判断依据。该方法能较好地区分直打孔、防尘、三防脱氧剂包装膜,适用于食品用脱氧剂包装膜“三防”性能的日常测试。

Detections of dust proof, water proof and oil proof on packaging film of deoxidizer for food

In this paper,the test methods of dust-proof,water-proof and oil-proof properties of deoxidizer packaging film for food were studied.The microscope observation method was used to test the dust-proof performance,and the folding box observation method was used to test the water-proof and oil-proof performance.After optimization,the test conditions were as follows:for dust-proof test,use a microscope to observe whether there is a straight hole;for water-proof test,use 10 mL,0.08% sodium dodecyl benzene sulfonate aqueous solution at room temperature;for oil-proof test,use 5 mL,60℃ olive oil;take the leakage time as the judgment basis for water-proof and oil-proof performance.This method can distinguish the three kinds of deoxidizer packaging film,such as direct drilling,dust-proof and three proofing.The methods were convenient,simple,stable and were suitable for the routine test of the"three proofing"performance of deoxidizer packaging film for food.
