Abstract
It the utility model is related to a kind of packaging bag, it is characterised in that：It includes outer packaging bag, is placed in the packing inside bag of the outer packaging bag inner chamber, and the upper limb of the upper limb of the packing inside bag and the outer packaging bag is tightly connected, so as to form sealing cavity layer between the outer packaging bag and packing inside bag；The sealing cavity layer is stretched into the bottom connection filling channel of the outer packaging bag, described filling channel one end, and the other end of the filling channel passes the outer packaging bag.
Description
Technical field
A kind of packaging bag is the utility model is related to, especially with regard to a kind of packaging bag suitable for fresh fruit of vegetables.
Background technology
At present, most commodity are packed in the form of inner packing adds outer packing.Wherein, inner packing is used for packing
Commodity, outer packing main function are the breakage for reducing inner packing, the friction and vibrations that reduce commodity.The advantages of this mode is mesh
The inner packing of front complement and the description of materials of outer packing are abundant, reliable in quality, cheap；Shortcoming is to need to be wrapped twice
Dress, cost is up for further reducing.
The packaging of fresh fruit of vegetables is usually to be packed using the packaging bag of polyethylene or polyvinyl chloride with air-vent,
The advantages of manner of packing is that fresh fruit of vegetables can continue that respiration occurs, and caused vapor can be scattered and disappeared by air-vent；
Shortcoming is the controlled atmospheric packing that can not carry out active, can not avoid the compression injury of product.
The content of the invention
It can reduce commodity crush injury in view of the above-mentioned problems, the purpose of this utility model is to provide one kind, reduce commodity
Packing cost and the packaging bag for improving commodity packaging efficiency.
To achieve the above object, the utility model uses following technical scheme：A kind of packaging bag, it is characterised in that：It is wrapped
Outer packaging bag is included, is placed in the packing inside bag of the outer packaging bag inner chamber, and the upper limb of the packing inside bag and the outer packaging bag
Upper limb be tightly connected so that between the outer packaging bag and packing inside bag formed sealing cavity layer；The bottom of the outer packaging bag
Portion connects filling channel, and the sealing cavity layer is stretched into described filling channel one end, and the other end of the filling channel passes institute
State outer packaging bag.
The outer packaging bag and packing inside bag are formed in one.
The packing inside bag is using hot sealing or sets Self-enclosing to seal.
A plurality of hot pressing line is set on the inwall of the packing inside bag, and it is multiple in the setting of the edge of the outer packaging bag
Fixing band.
The fixing band uses fiber, paper, polyethylene, polyvinyl chloride, polypropylene or aluminium foil polyethylene composite.
Multiple air-vents are set on the packing inside bag, and the air-vent is used to connecting the packing inside bag and described close
Seal cavity layer.
The aperture of the air-vent is 1~1000 μm.
The outer packaging bag and packing inside bag use polyethylene, polyvinyl chloride, polypropylene or aluminium foil polyethylene composite.
For the utility model due to taking above technical scheme, it has advantages below：1st, the utility model uses interior outsourcing
Pack is tightly connected, and forms sealing cavity layer between the two, and filling channel passes through outer packaging bag bottom communication seals cavity layer, business
Only once package encapsulation in packing inside bag, reduces commodity packaging cost to product, improves commodity packaging efficiency；Meanwhile pass through inflation
Passage is inflated to outer packaging bag, and gas buffer layer is formed in outer packaging bag, can reduce the crush injury of commodity.2nd, this practicality
New packing inside bag is sealed using hot sealing or Self-enclosing, sets a plurality of hot pressing line after sealing on packing inside bag, outside
The edge of packaging bag sets multiple fixing bands, can position of the affixed merchandise in packaging bag, that reduces commodity rocks collision.
The 3rd, multiple air-vents, air-vent connection packing inside bag and sealing cavity layer are set on packing inside bag of the present utility model, to commodity
Play preservation.4th, exterior and interior packing bag of the present utility model is using polyethylene, polyvinyl chloride, polypropylene, aluminium foil polyethylene etc.
Material, these material sources are extensive, and cost is low, can reduce the production cost of packaging bag.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model includes outer packaging bag 1 and is placed in the packing inside bag 2 of the inner chamber of outer packaging bag 1, and it is interior
The upper limb of packaging bag 2 is tightly connected with the upper limb of outer packaging bag 1, so that it is empty that sealing is formed between outer packaging bag 1 and packing inside bag 2
Cavity layer 4.Sealing cavity layer 4 is stretched into the bottom connection filling channel 3 of outer packaging bag 1, the one end of filling channel 3, and the other end passes outer
Packaging bag 1.
In above-described embodiment, outer packaging bag 1 and packing inside bag 2 are formed in one.
In above-described embodiment, as shown in figs. 2 to 4, packing inside bag 2 is using hot sealing or sets Self-enclosing 6 to seal, for more
Position of the good affixed merchandise in packing inside bag 2, avoids commodity from being rocked in packing inside bag 2, reduces the collision between product,
A plurality of hot pressing line 5 is set on the inwall of packing inside bag 2, and multiple fixing bands 7 are set in the edge of outer packaging bag 1, it is fixed
Band 7 is using fiber, paper, polyethylene, polyvinyl chloride, polypropylene or aluminium foil polyethylene composite etc..
In above-described embodiment, as shown in figure 5, in packaging fresh fruits and vegetables, to ensure the freshness of fruits and vegetables, in packing inside bag
Multiple air-vents 8 are set on 2, and the aperture of air-vent 8 is 1~1000 μm, so, is filled by filling channel 3 into outer packaging bag 1
