Abstract

The utility model relates to a vacuumized packaging bag with an anti-oxidation function, which cannot affect the purity of material. The body of the packaging bag is provided with two layers; wherein, the outer layer (1) is an airtight isolating layer; the inner layer (2) is an air-permeable layer capable of blocking solid powder; the inner and the outer layers are bound together to form a circumferentially sealed cavity (4); antioxidant is filled in the cavity; and the packaging bag is also provided with an exhaust tube (3), one end of which is exposed out of the outer layer (1) to communicate with the atmosphere and the other end of which is connected with the wall body of the inner layer (2). The packaging bag can ensure that the packaged material can be fully isolated from the air and protected by the antioxidant without being polluted, so that the material can be effectively prevented from oxidative deterioration.

Description

A kind of vacuum packaging bag with anti-oxidation function

Technical field

The utility model relates to a kind of vacuum packaging bag, especially a kind of vacuum packaging bag with anti-oxidation function.

Background technology

Part material, usually unstable as medicine chemical material etc., in the process of accumulating in case contact the just easy moisture absorption, oxidation deterioration with air.Therefore in order to guarantee the stability of material, the general mode of enclosed package that adopts is packed it in the prior art.But because this class material generally is pulverulence, fly upward easily, conventional meanses such as employing vacuum packing machine can't extrude the air of bag to keep vacuum state, therefore, even airtight, but the air that remains in the packaging process in the bag still can quicken the rotten of material.In order to prevent the material oxidation, generally can adopt the method that adds antioxidant in the prior art, the latter often directly is blended in the material, though played the sludgeproof effect, itself has also become impurity, has influenced the purity of material.

The utility model content

The technical problems to be solved in the utility model can prevent effectively that for providing a kind of material from contacting with air, has not only had anti-oxidation function but also can not influence the vacuum packaging bag of feed purity.

The bag of the vacuum packaging bag that the utility model is related has two-layer, and skin is sir-tight barrier layer, and internal layer is for intercepting the air-permeable layer of pressed powder, and ectonexine partly bonds with closed chamber around forming, and is filled with antioxidant in this chamber; Packaging bag also has an extraction pipe, and an end of this extraction pipe exposes skin and communicates with atmosphere, and the other end is connected on the internal layer wall body, during use, by this extraction pipe the gas in the bag is extracted out, to keep vacuum state.

Described skin is made by one or more materials in polyethylene, polypropylene, polystyrene, polyamide, polyester, polyvinyl alcohol, polyvinylchloride, polyvinylidene chloride, ethylene-vinyl alcohol copolymer, ionomer, the aluminium foil.

Described internal layer is made by bag filter paper or nonwoven fabrics, and these two kinds of materials can intercept pressed powder by actv., can prevent the pollution of antioxidant to material again.

Chamber between the ectonexine can be that a big chamber constitutes, and also can be made up of several separate capacitors.

Described antioxidant is one or more in vitamin C derivatives, EDTA-2Na, day intrinsic safety Ge Lesi series oxygen absorbent, Japanese Fu Laisile series oxygen absorbent, the U.S. Fu Laisipa series oxygen absorbent.

During use, after the end closure that described extraction pipe communicates with atmosphere, be fully enclosed in the whole packaging bag.

In the packaging process, material is enclosed packaging bag, bleed by extraction pipe with air extractor, air in the bag, comprise that the air in the chamber will be drawn out of, because an end of this extraction pipe is directly to be bonded on the inner layer wall, this mouth of pipe that just is equivalent to bleed is surrounded by one deck filtering net, and actv. has prevented that solid material is drawn out of.After air was taken out to the greatest extent, at this moment the end that the sealing extraction pipe communicates with atmosphere, just was vacuum state in the whole packaging bag.

Owing to be filled with antioxidant in the chamber between the ectonexine, formed barrier one in the periphery of material.Because the obstruct of internal layer, antioxidant again not can with mixing of materials, avoided material is polluted.

In sum, adopt the related vacuum packaging bag of the utility model, can guarantee that material and the air adorned are isolated fully, and under not contaminated state, be protected that actv. has prevented this material oxidation deterioration by antioxidant.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a cutaway view of the present utility model.

The specific embodiment

The bag of Fig. 1, vacuum packaging bag shown in Figure 2 has two-layer, and outer 1 is sir-tight barrier layer, is made by aluminium foil; Internal layer 2 is made by bag filter paper for intercepting the air-permeable layer of pressed powder; Ectonexine at the chamber 4 of upper and lower side bonding with closure around forming, is filled with antioxidant-vitamin C in this chamber respectively; Packaging bag also has an extraction pipe 3, and an end of this extraction pipe exposes outer 1 and communicates with atmosphere, and the other end is connected on internal layer 2 wall bodies.

In the packaging process, material is enclosed packaging bag, bleed by extraction pipe with air extractor, after air was taken out to the greatest extent, at this moment the end that the sealing extraction pipe communicates with atmosphere, just was vacuum state in the whole packaging bag.
