Problems solved by technology

At present, all deoxidizers use through-through, single-proof or multi-proof packaging materials. When this kind of deoxidizer is used in dry environment products, the moisture contained in the raw material of the deoxidizer will be easily absorbed by the dry environment and lost due to the air holes of the packaging materials. The performance of the deoxidizer will deteriorate, and the oxygen concentration in the package cannot be effectively reduced to a safe range
[0004] For products that have requirements on the appearance of the packaging container, the replacement type deoxidizer used in general packaging materials releases an unbalanced and unstable ratio of oxygen and carbon dioxide, which can easily lead to a negative pressure state in the packaging container; thus affecting product quality and appearance

Abstract

The invention discloses a deoxidizing agent packaging film and a preparation method thereof. The deoxidizing agent packaging film comprises oil-resistant waterproof paper, and the two opposite sides of the oil-resistant waterproof paper are coated with a layer of perforated PE film and a layer of perforated PET film respectively. The thickness of the perforated PE film is 25-50 [mu] m, and the thickness of the perforated PET film is 10-15 [mu] m. The perforated holes in the step 2 and the step 3 do not break through the oil-resistant waterproof paper so that the powder leakage phenomenon of the deoxidizing agent package is avoided, the package can be in direct contact with inclusions, and no dust leaks out. Meanwhile, the oil-resistant waterproof paper can prevent moisture and oil in the inclusions from eroding the deoxidizing agent, and potential safety hazards and hazards such as inclusion pollution caused by leakage of the deoxidizing agent are avoided. The deoxidizing agent packaging film is simple in preparation process and structure, convenient to use, good in transparency and particularly suitable for deoxidizing agent packaging containing indication marks.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a deoxidizer packaging film and a preparation method thereof. Background technique [0002] Deoxygenation packaging (FOA) refers to the use of a deoxidizer that can chemically react with oxygen or catalyze oxygen in a sealed packaging container to remove free oxygen in the packaging container, so that the packaged objects can be stored at a high oxygen concentration. Low (oxygen < 0.1%), even an oxygen-free state of preservation of a technology. [0003] Packaging materials used for deoxygenation packaging are required to have good airtightness, especially high barrier properties to oxygen, and the specific requirement is that the permeability to oxygen is less than 20mL / (m2·24h·0.1MPa, at 20°C) . The packaging material or container should preferably have a certain strength to avoid unattractive appearance caused by shrinkage caused by negative pressure. At pres...
