Problems solved by technology

However, since the entire layer of adhesive glue layer and oil-proof layer are arranged on the air-permeable film, it is easy to cause the air-permeable effect of the packaging material in the prior art to deteriorate.

Embodiment 1

[0059] Embodiment 1: A kind of packaging material of dust-proof oxygen-permeable deoxidizer, such as figure 1 As shown, it includes a polyethylene co-extrusion layer 1, a first adhesive layer 4, a dustproof paper layer 2, a second adhesive layer 5, and a dustproof paper layer 3. Usually, the dustproof paper layer 3 is the outer layer, and the polyethylene co-extrusion layer Extruded layer 1 is the inner layer. Apply glue on both surfaces of the dust-proof paper layer 2 (the glue is composed of Dow water-based glue L-168, Dow curing agent CR3A, and carboxymethyl cellulose with a weight ratio of 100:2:1) .

[0060] Wherein, the polyethylene co-extruded layer 1 and the dust-proof paper layer 3 are provided with vent holes 6, and the aperture of the vent holes 6 is 0.3 mm, and the vent holes 6 are formed on the polyethylene co-extruded layer 1 and the dust-proof paper layer 3. The hole spacing is 1 mm.

Embodiment 2-6

[0079] Embodiment 2-6: A dust-proof, oxygen-permeable and deoxidizer packaging material, the difference from Example 1 is the thickness of the polyethylene co-extrusion layer 1 and the dust-proof paper layer 3, the quantification of the dust-proof paper layer 2, and the second The coverage of the first glue layer 4 and the second glue layer 5 on the dust-proof paper layer 2 and the usage amount of glue therein, the usage amount of the ink are as shown in Table 1, and the polyethylene co-extrusion layer 1 in embodiment 1-3 The consumption of each raw material in outer layer, middle layer, inner layer is as shown in table 2, and the usage amount of each raw material in outer layer, middle layer, inner layer in the polyethylene coextruded layer 1 in embodiment 4-6 As in Example 1; the amount of softwood pulp, hardwood pulp, and processing aids contained in the dustproof paper layer 2 is shown in Table 3.

Embodiment 7

[0080] Embodiment 7: A dust-proof, oxygen-permeable and deoxidizer packaging material. The difference from Embodiment 1 is that the holes in the polyethylene co-extrusion layer 1 gradually expand in the shape of a cone from the outer layer to the inner layer, and the largest hole diameter on the outer layer is is 0.25mm, and the largest hole diameter on the inner layer is 0.4mm. The vent hole 6 on the dustproof paper layer 3 is gradually reduced from the side close to the dustproof paper layer 2 to the side away from the dustproof paper layer 2, and the largest The hole diameter is 0.3mm, and the smallest hole diameter is 0.4mm; and the hole spacing of the ventilation holes 6 on the polyethylene co-extrusion layer 1 and the dustproof paper layer 3 is 3mm.

Abstract

The invention discloses a dustproof and oxygen-permeable deoxidizer packaging material and a production process thereof. The dustproof and oxygen-permeable deoxidizer packaging material comprises a polyethylene co-extrusion layer, a dustproof paper layer and a polyester film layer; glue layers are arranged between the polyethylene co-extrusion layer and the dustproof paper layer and between the dustproof paper layer and the polyester film layer; the gram weight of the glue in each glue layer is 3-5 g / m <2>, and the coating probability of the glue on the two surfaces of the dustproof paper layer is 50-60%; and air holes are formed in the polyethylene co-extrusion layer and the polyester film layer. The dustproof and oxygen-permeable deoxidizer packing material has the advantages of good dustproof effect and good ventilation effect.

Description

technical field [0001] The invention relates to the technical field of packaging materials, more specifically, it relates to a dust-proof, oxygen-permeable and deoxidizer packaging material and a production process thereof. Background technique [0002] Deoxidizer is an additive that absorbs oxygen and slows down the oxidation of food, and is usually a chemical mixture that easily reacts with free oxygen or dissolved oxygen. Wrap it and seal it with the food, it can remove the oxygen remaining in the air in the bag, prevent the food from oxidative discoloration, deterioration and oil rancidity, and also inhibit the growth of mold, aerobic bacteria and food pests. At present, deoxidizers are not only used to maintain food quality, but also used for preservation and rust prevention of grain, feed, medicine, clothing, fur, precision instruments and other items. [0003] The Chinese patent with application publication number CN107264980A and application publication date of Octo...
