Abstract
The utility model discloses an oil-proof and water-proof deoxidizing agent, a drying agent or a preservative of a ventilating window with an oxygen indicating line. The utility model can not leak powder, and can isolate the oxygen indicating line from food, thereby improving the food safety.
Description
Technical Field
The utility model belongs to the field of deoxidizing agents, and particularly relates to an oil-proof and water-proof deoxidizing agent, a drying agent or a preservative with an oxygen indicating line ventilation window.
Background
In modern food packaging process, generally can make into the wrapping bag through the packaging film and seal including food package to protect inside food, when convenient transportation storage, make things convenient for food to keep long-time fresh degree, partial fresh food still can put into the oxidation of pouch deoxidier in order to reduce inside food in the wrapping bag, makes things convenient for fresh food's long-time storage. Oxygen indicator lines are also usually provided in the deoxidizer to indicate whether the deoxidizer is effective.
The problems of the deoxidizer in the current market are as follows: 1. the risk of powder leakage exists; 2. the oxygen indicator line is exposed outside, and the color-changing component has certain safety risk when contacting food and human body.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide an oil-proof and water-proof deoxidizing agent, a drying agent or a preservative with an oxygen indicating line ventilation window aiming at the defects of the background art, so that powder can not leak, the oxygen indicating line can be isolated from food, and the food safety is provided.
The utility model adopts the following technical scheme for solving the technical problems:
take grease proofing waterproof type deoxidier, drier or antistaling agent of oxygen indication line transom, make the wrapping bag by the packaging material banding, pack deoxidier, drier or antistaling agent granule in the wrapping bag and make, be located in the wrapping bag and be equipped with the oxygen indication line between two banding to this oxygen indication line both ends heat-seal is inside the banding, the oxygen indication line is including the oxygen indication cotton thread that has the oxygen indicator, the oxygen indication cotton thread is inboard at the wrapping bag through the fixed seal of plastic film that has the bleeder vent, the wrapping bag is located the region at oxygen indication line place and is provided with the bleeder vent.
Further, the packaging material is formed by compounding a PET layer and a CPP layer, the CPP layer is an inner layer, and the PET layer is an outer layer.
Furthermore, the plastic film is fixedly connected with the inner side of the packaging bag through glue.
Furthermore, the plastic film is a hot-melt plastic film and is fixed with the packaging bag in a hot-melt adhesion mode.
Compared with the prior art, the utility model adopting the technical scheme has the following technical effects:
1. the packaging material of the oxygen agent, the drying agent and the antistaling agent adopts an incompletely perforated full-plastic (such as PET/CPP) composite material, the oil-proof and water-proof performance of the packaging material is far superior to that of a so-called three-proof film on the market at present, the material cost is lower, perforation is not needed, and the problem of powder leakage is avoided;
2. the process problem is not complicated and is easy to solve, air can enter from the ventilation window to contact with the oxygen indicating cotton thread and then react with the deoxidizer through the ventilation hole of the plastic film;
3. the product safety is greatly improved, and the deoxidation effect is obvious.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a structural view of the packaging bag of the present invention before heat-sealing.
In the figure, 1, a packaging bag; 11. a ventilation window; 2. a plastic film; 21. oxygen indicates cotton thread.
Detailed Description
The technical scheme of the utility model is further explained in detail by combining the attached drawings:
the utility model provides an oil-proof and waterproof deoxidizer, a desiccant or a preservative with an oxygen indicating line vent window, as shown in figures 1 and 2, a packaging bag 1 is made by sealing edges of packaging materials, deoxidizer, desiccant or preservative particles are filled in the packaging bag 1, an oxygen indicating line is arranged between two sealing edges of the packaging bag 1 in the packaging bag 1, two ends of the oxygen indicating line are heat-sealed in the sealing edges, the oxygen indicating line comprises an oxygen indicating cotton line 21 with an oxygen indicator, the oxygen indicating cotton line 21 is fixedly sealed and attached to the inner side of the packaging bag 1 through a plastic film 2 with vent holes, and vent holes are arranged in the area of the packaging bag 1 where the oxygen indicating line is located.
Further, the packaging material is formed by compounding a PET layer and a CPP layer, the CPP layer is an inner layer, and the PET layer is an outer layer.
Further, the plastic film 2 is fixedly connected with the inner side of the packaging bag 1 through glue.
Further, the plastic film 2 is a hot-melt plastic film, and is fixed with the packaging bag 1 through hot-melt adhesion.
When the utility model is produced:
1. firstly, forming ventilation holes in the area of the packaging material for arranging the oxygen indicating lines to form a ventilation window 11, then making a cotton line with the oxygen indicator into a strip, a sheet or a thread without imitation cloth strips and the like, and then fixing and sealing the area of the ventilation window 11 of the packaging bag 1 by using a plastic film 2 with the ventilation holes. Plastic film 2 passes through glue and 1 inboard fixed connection of wrapping bag, perhaps plastic film 2 chooses for use hot melt plastic film, and it is fixed through the mode that hot melt bonds between 1 with the wrapping bag, and the packaging material of wrapping bag 1 is formed by PET layer and CPP layer complex to the CPP layer is the inlayer, and the PET layer is outer, and the CPP layer has hot melt, and it can hot melt with hot melt plastic film 2 and be connected.
2. The two ends of the oxygen indicating cotton thread 21 are sealed in the sealed edges of the packaging bag 1, and the end part of the oxygen indicating cotton thread 21 is not exposed outside the sealed edges of the packaging bag 1, so that the packaging bag 1 of the utility model does not need to be perforated completely (the oil-proof and water-proof effects are good), the deoxidizer, the desiccant and the preservative agent in the packaging bag 1 cannot leak out (although the packaging bag 1, the plastic film 2 and the oxygen indicating cotton thread 21 are perforated, the powder leakage probability is very small), air can enter the breathable plastic film 2 from the ventilation window 11 to react with the oxygen indicating cotton thread 21, and then enters the packaging bag 1 from the ventilation holes of the plastic film 2 to react with the deoxidizer. The oxygen indicating cotton thread 21 of the present invention is sealed in the packaging bag 1, which not only ensures good air permeability, but also does not directly contact with food, and improves safety. The oxygen indicating cotton thread 21 of the present invention may be alcohol soaked common cotton thread to obtain deoxidant with disinfection function.
