Abstract
The utility model discloses a crops germplasm resources vacuum storage bag, the bag body of making including plastic film, wherein, the bag body all around with the sealing strip that the middle part was hot pressing together, was day font, respectively be equipped with one in the sealing line at this bag body both ends from the strip of paper used for sealing, be equipped with the easy tear mouth of mutual correspondence on the sealing strip both sides between corresponding this self-sealing strip and the adjacent sealing strip. The bag body is made of an Al + PA + PE composite film, and the total thickness is 0.14 mm. The utility model has the advantages that: the double openings are reserved, when seeds need to be taken, one side is torn, at the moment, one half of the seeds are sealed by the self-sealing strips, and the other half of the seeds can still be stored in vacuum, so that the storage life of the seeds is prolonged, and the seeds are convenient to store, distribute and share; the AL + PA + PE composite aluminum foil material is adopted, so that the seed storage and distribution device is soft, durable and good in sealing degree, and is convenient for seed storage and distribution.
Description
Technical Field
The utility model relates to a crop germplasm resources vacuum preservation bag, mainly used preservation of crops seed.
Background
The crop germplasm resources are the most valuable precious wealth for human survival and development, are national important strategic resources, are the material basis for crop breeding, biological science research and agricultural production, and are the important guarantee for realizing grain safety, ecological safety and agricultural sustainable development. Therefore, the countries in the world pay great attention to the proper preservation and effective utilization of the germplasm resources of crops. The three main factors determining the seed life in the storage process are the oxygen content, the moisture content and the temperature respectively, the crop germplasm resources stored in a global low-temperature bank in a seed form reach millions, and the seeds currently stored in the national crop germplasm bank reach more than dozens of thousands. However, most of the materials for germplasm resource storage currently adopt paper bags, aluminum boxes, plastic bottles, vacuum packaging bags and the like. Although few vacuum packaging bags are used, seeds are generally sealed in a plastic bag, and the storage materials have the following defects: once a part of seeds need to be removed, the sealing bag needs to be opened, so that the seeds in the bag are completely exposed to the air, and the storage period of the seeds is inevitably shortened; the residual seeds need to be stored again, and the plastic bag needs to be vacuumized and sealed again, so that the operation is very troublesome, and the storage, the distribution and the sharing of germplasm resources are inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a crops germplasm resources vacuum storage bag to solve the above-mentioned problem that prior art exists.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a crops germplasm resources vacuum storage bag, includes the bag body that plastic film made, wherein, the bag body all around with the middle part be hot pressing sealing strip that is the day font together, respectively be equipped with one in the sealing line inner limit at this bag body both ends and proclaim oneself the strip, be equipped with the easy tear mouth that corresponds each other on the sealing strip both sides between corresponding this proclaim oneself strip and the adjacent sealing strip.
The bag body is made of Al + PA + PE composite film, and the total thickness is 0.1-0.2 mm.
The utility model has the advantages that: the double openings are reserved, when seeds need to be taken, one side is torn, at the moment, one half of the seeds are sealed by the self-sealing strips, and the other half of the seeds can still be stored in vacuum, so that the storage life of the seeds is prolonged, and the seeds are convenient to store, distribute and share; the AL + PA + PE composite aluminum foil material is adopted, so that the seed storage and distribution device is soft, durable and good in sealing degree, and is convenient for seed storage and distribution.

Description of reference numerals: 1. the bag body, 2, sealing strip, 3, easily tear mouth, 4, self-sealing strip.
Detailed Description
Referring to fig. 1 and 2, the utility model relates to a crops germplasm resources vacuum storage bag, bag body 1 made including plastic film, wherein, bag body 1 all around with the middle part be hot pressing together, be sealing strip 2 of day font, respectively be equipped with one in the sealing line of this bag body 1 both ends from strip 4, be equipped with the easy tear mouth 3 of mutual correspondence in corresponding this from strip 4 and the 2 both sides of sealing strip between the adjacent sealing strip 2.
The bag body 1 can be made of (but not limited to) an Al + PA + PE composite film, and the total thickness is 0.14 mm. The utility model discloses a typical dimension of bag body 1 does: the opening length is 120mm, and the depth of each bag body 1 is 120 mm.
The utility model discloses be two disjunctor sealing bags in fact, there is sealing strip 2 separately at the middle part, and both sides edge also seals with sealing strip 2, and the opening at both ends is equipped with from sealing strip 4, takes the evacuation to form sealing strip 2 at both ends hot pressing after packing into the germplasm resources that will save. When seeds need to be taken, the seeds are torn from the easy-tear opening 3 at one end of the bag body 1, and the seal of the self-sealing strip 4 is opened, so that the seeds are conveniently distributed and shared; and the seeds in the other half of the bag body 1 can still be guaranteed to be stored in vacuum, so that the storage life of the seeds is prolonged.
