Abstract
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.
