Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing:
[0033] Such as figure 1 As shown, a three-proof food preservative packaging bag and its preparation method include PE film layer 001, wrapping paper layer 002 and PET film layer 003, PE film layer 001 is used to wrap around the preservative, and wrapping paper layer 002 sticks Closed on the outer periphery of the PE film layer 001, the PET film layer 003 is bonded to the outer periphery of the wrapping paper layer 002, and there are multiple groups of first air holes 004 uniformly distributed and penetrating through the PE film layer 001 on the PE film layer 001, and on the PET film layer 003 There are multiple groups of second air holes 005 that are evenly distributed and run through the PET film layer 003. The shapes of the first air holes 004 and the second air holes 005 are both quadrangular pyramids. The first air holes 004 and the second air holes 005 have small apert...

The invention provides a three-proofing food preservative packaging bag which comprises a PE film layer, a packaging paper layer and a PET film layer, the PE film layer is used for wrapping the periphery of a preservative, the packaging paper layer adheres to the periphery of the PE film layer, the PET film layer adheres to the periphery of the packaging paper layer, multiple sets of first air holes which are evenly distributed and penetrate through the PE film layer are formed in the PE film layer, and the first air holes are communicated with the PE film layer. The PET film layer is provided with a plurality of groups of second air holes which are uniformly distributed and penetrate through the PET film layer, the first air holes and the second air holes are rectangular pyramid-shaped, the small-aperture ends of the first air holes and the second air holes face one side of the preservative, the packaging paper adopts oil-proof and water-proof paper, the distance between two adjacent groups of first air holes is 1.5-2.5 mm, and the distance between two adjacent groups of second air holes is 1.5-2.5 mm. And the distance between two adjacent groups of second air holes is 3.5-4.5 mm. The packaging bag has the advantages that the air permeability of the packaging bag is ensured, and meanwhile, the safety during use is also ensured.
Description
technical field [0001] The invention relates to the technical field of packaging bag production, in particular to a three-proof food preservative packaging bag and a preparation method thereof. Background technique [0002] Wrapping paper is mostly used for packaging food deoxidizers. Wrapping paper is used to make sealed paper bags and pack deoxidizers. After putting them into food packaging bags, the deoxidizers in the wrapping paper can absorb the oxygen in the food packaging bags and play a role. To prevent food oxidation purposes. [0003] Most of the existing deoxidizer packaging bags are made of non-woven fabric and breathable film bonded by glue. There are two major problems in the use of this kind of packaging bag. One: because the deoxidizer is in powder form, the powder deoxidizer It is easy to seep out from the film holes of the non-woven fabric and the breathable film, contaminating food; second: the glue coating is evenly applied, which is easy to block the fi...
