Abstract
A plastic vacuum packaging bag comprises two plastic films formed through hot pressing and binding manner. The plastic vacuum packaging bag adopts a secondary sealing manner and can easily and completely extract air in the bag, a ventilating straight line is formed through evenly-spaced holes left when the pressing and binding are conducted at the lower part of the bag, a lower sealing line parallel to the ventilating straight line is formed at the lower part of the ventilating straight line, and an air extracting hole is reserved on the lower sealing line. The utility model has the advantages that the plastic vacuum packaging bag can avoid the pest breeding in the grain including rice and dust pollution, and the storage time of products is prolonged.
Description
Technical field
The utility model relates to for example plastic packaging bag of rice (below be omitted) of food in bulk material, relates to a kind of plastics vacuum packaging bag particularly.
Background technology
Traditional plastic packaging bag is to form with 2 rectangular film hot pressing or stitching, when being unkitted food material, 4 jiaos are the right angle, behind the dress material, 4 angles are sharp-pointed taper, easily become the gathering ground of insect or dust, neither attractive in appearance, and because bag contains air, be unfavorable for the food long term storage, the infringement food quality.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of plastic packaging bag, and providing a kind of four jiaos is arc, seals the vacuum plastic packaging bag that the below has a ventilative straight line to deflate on the top has.
This plastics vacuum packaging bag, comprise the plastic sheeting of 2 heat pressure adhesives, it is characterized in that cementing line is formed by connecting by the dual-side of rectangular film, the segmental arc gone up on sealing line, ventilative straight line and 4 angles, be provided with sealing line and portable limit above the sack, reserve at interval hole uniformly during sack below pressing, the aperture forms a ventilative straight line less than the particle diameter of material, below ventilative straight line, lower sealing line with ventilative straight line parallel is arranged, on the lower sealing line, be reserved with bleeding point.
After packaging bag both sides and bottom pressing, from sealing the can rice, will seal pressing on the top then, again from bleeding point with the air extraction between the grain of rice in the bag, at last the bleeding point pressing is shut.
The utility model has the advantages that: 1. after the can air in the bag is drained only, formed vacuum state, can prevent that the food insect that comprises rice from growing or dust pollution, prolonged the storage time of product.2. the overall image of packaging bag that around is fillet is more attractive in appearance.3. reduce volume in the transportation, reduced carrying intensity.
Description of drawings
Fig. 1 is the utility model front view
Among the figure: 1, side, 2, go up sealing line, 3, portable limit, 4, ventilative straight line, 5, segmental arc, 6, the lower sealing line, 7, bleeding point
The specific embodiment
As follows according to elaboration the utility model implementation process shown in Figure 1:
2 rectangular film are passed through hot forming, cementing line is formed by connecting by the dual-side 1 of rectangular film, the segmental arc 5 gone up on sealing line 2, ventilative straight line 4 and 4 angles, be provided with sealing line 2 and portable limit 3 above the packaging bag, reserve at interval hole uniformly during packaging bag below pressing, the aperture forms a ventilative straight line 4 less than the particle diameter of material, below ventilative straight line 4, a lower sealing line 6 parallel with ventilative straight line 4 is arranged, on lower sealing line 6, be reserved with bleeding point 7.
Claims (1)
1, a kind of plastics vacuum packaging bag, the plastic sheeting that comprises 2 heat pressure adhesives, it is characterized in that, cementing line is by the dual-side (1) of rectangular film, last sealing line (2), segmental arc (5) on ventilative straight line (4) and 4 angles is formed by connecting, be provided with sealing line (2) and portable limit (3) above the packaging bag, reserve at interval hole uniformly during packaging bag below pressing, the aperture is less than the particle diameter of material, form a ventilative straight line (4), in ventilative straight line (4) below, a lower sealing line (6) parallel with ventilative straight line (4) is arranged, on lower sealing line (6), be reserved with bleeding point (7).
