Abstract
The invention relates to the technical field of living articles, in particular to a wrapping bag beneficial to food storage. The wrapping bag at least comprises an outer layer, an inner layer and a thermal insulation layer arranged between the outer layer and the inner layer. The wrapping bag is provided with a bag opening communicated with an inner cavity and an air extraction valve. The food wrapping bag is in a multi-layer structure; due to arrangement of the thermal insulation layer, the functions of seal, thermal insulation and light resistance are achieved; air in the bag is pumped out through the air extraction valve to enable the wrapping bag to be in a vacuum state, proper protective air can be filled in the wrapping bag through the air extraction valve, and therefore a good internal environment is created for food stored in the bag, and the food wrapping bag has the advantages of being long in preservation time, solid, durable, easy to manufacture, low in price and wide in application range and the like, and can be widely used in preservation of vegetables, meat and fruit and the like.
Description
Technical field
The present invention relates to technical field of living goods, espespecially a kind of packaging bag that is beneficial to food storage.
Background technology
At present, the food preserving bag that uses in the life is generally individual layer, and it is by being evacuated to reach the purpose of food fresh keeping in will declining.But because the ambient pressure effect very easily causes freshness protection package damaged; And when external temperature was higher, because freshness protection package is close to food, and the heat energy of food absorption can't be emitted, thereby causes interior green-house effect, very easily causes food decay, rotten.As seen, above-mentioned freshness protection package can not satisfy people far away to the requirement of food fresh keeping.
Summary of the invention
The object of the invention is to overcome the defective of prior art, a kind of packaging bag that is beneficial to food storage that provides.
For achieving the above object, the present invention adopts following technical scheme:
Food pack, this packaging bag at least by outer, internal layer and be folded in skin and internal layer between thermal insulation layer form, packaging bag is provided with sack and the evacuating valve of communication with cavity.
The present invention has multiple-structure; and be provided with the effect that thermal insulation layer has played sealing, heat insulation, resistance light, by evacuating valve air in the bag extracted out, form vacuum; and suitable atmosphere gas can be fed in the bag from this evacuating valve; store food has caused a good internal environment in the bag thereby give, and it is long to have fresh keeping time, durable; make simple; cheap, the advantage such as widely applicable can be widely used in the fresh-keeping of vegetables Lay, meat, fruit etc.
Description of drawings:
Accompanying drawing l is structural representation of the present invention.
The specific embodiment:
The present invention is further described below in conjunction with accompanying drawing:
Consult shown in Figure 1, food pack provided by the invention, its at least by outer 1, internal layer 2 and be folded in outer 1 and internal layer 2 between thermal insulation layer 3 form, packaging bag is provided with sack 4 and the evacuating valve 5 of communication with cavity.
During use; food is after treatment put into packaging bag from sack 4; then with band sack 4 is tightened rapidly, then from evacuating valve 5 air in the bag is extracted out, form vacuum; again with atmosphere gas; such as nitrogen etc., be fed into the bag from evacuating valve 5, like this; food can reach good fresh-keeping effect in the bag under the duplicate protection of thermal insulation layer 3 and atmosphere gas.
Claims (1)
1. food pack is characterized in that: this packaging bag at least by outer (1), internal layer (2) and be folded in skin (1) and internal layer (2) between thermal insulation layer (3) form, packaging bag is provided with sack (4) and the evacuating valve (5) of communication with cavity.
