Description

Vacuum grain bag

Technical Field

The utility model belongs to the technical field of the wrapping bag technique and specifically relates to a vacuum line bag is related to.

Background

The common vacuum bag in the current market is two layers of smooth surfaces, so that the upper layer and the lower layer are very easy to be attached together to form wrinkles, the air exhaust is not smooth, the phenomenon of air residue is caused, the appearance is not smooth, and the quality of packaged food is influenced due to the defects. The smooth vacuum bag is easy to break and has great influence on the appearance of the food filled in the bag, thereby having potential food safety hazard.

Therefore, vacuum line bags appear on the market, the existing vacuum line bags have lines such as diamond shapes and double-sided twills, but the vacuum line bags are difficult to manufacture, the temperature control requirement is high, large pressure values are required, the cost is high, the continuous vacuum pumping performance of the vacuum line bags is not good, and after each vacuum sealing of the vacuum bags is finished, the next vacuum sealing operation can be continued only after the heating wire or the silica gel of a machine is cooled. In addition, in order to maintain good vacuum-pumping performance, the thickness of the grain surface must be made to be relatively deep, which results in that the grain bag is relatively thick and the transportation cost is increased.

When the vacuum grain bag is processed in the prior art, the grain is embossed by an embossing machine, the existing mode is that the embossing machine is used for extruding protrusions, and air-exhaust dents are reserved, so that the working pressure ratio of the embossing machine is easily larger.

Disclosure of Invention

The utility model aims at: in order to overcome the defects of the prior art, the utility model provides a vacuum texture bag, it utilizes the embosser to directly extrude the recess, and impressed watermark thickness is little, reduces the cost of transportation.

The technical scheme of the utility model: the utility model provides a vacuum line bag, includes the bag body, be equipped with the holding chamber that is used for holding article on the bag body, the even distribution has a plurality of recesses on the surface of at least one of them bag face of the bag body, and each recess interval sets up, and forms the bellied bump to another bag face between two adjacent recesses, and each recess switches on each other and forms and can guide the air of holding intracavity to the outer air guide groove of bag body.

By adopting the technical scheme, the vacuum bag with better continuous vacuum-pumping performance can be manufactured by using small embossing thickness, the air in the bag can be pumped more cleanly, a higher negative pressure value is achieved, meanwhile, the pressure and the temperature of the vacuum film material during production and manufacturing are reduced, the process requirement is reduced, the energy consumption is reduced, the thickness of the vacuum embossing surface is reduced, the transportation cost can be effectively reduced, the material requirement is lower, and the vacuum embossing bag with the same performance can be manufactured without using an embossing film with a specific formula.

The utility model discloses a further set up: the thickness of each groove is 0.2 to 0.4mm.

Preferably, the thickness of each groove is 0.25mm.

By adopting the further arrangement, the supporting force generated is different according to the different cross-sectional shapes of the air guide grooves, the thickness of the grain surface can be changed accordingly, the thickness of the vacuum grain surface is reduced, and the transportation cost can be effectively reduced.

The utility model discloses a further setting again: the cross section of the air guide groove is arc-shaped or trapezoid.

Adopt above-mentioned further setting again, make things convenient for guide air to discharge more, processing is also more convenient simultaneously.
