Abstract
Disclosed is a plastic composite venting packing bag, which mainly comprises a bag body 1. The utility model is characterized in that a narrow-bar non-woven fabric 2 is compounded in the seam of the bag body 1, countless tiny venting holes 3 are arranged on the non-woven fabric 2. The utility model has the advantages that when the object is charged, the pressure rises in the bag and the gas is exhausted from the venting hole 3 on the non-woven fabric 2 which is compounded in the seam of the bag body 1 because the narrow-bar non-woven fabric 2 is compounded in the seam of the bag body 1. The residual gas can be exhausted in the bag after the product is packed, which can not only reduce air in the packing bag, improve and lengthen the guarantee period of the product, but also can reduce the damage of the packing bag when conveying or piling the product and is more convenient to pile the product tidy. The utility model is especially fitful for packing rice corn. Otherwise, the utility model also has the advantages of simple structure, low manufacturing cost and the like.
Description
Technical field
The utility model relates to a kind of packaging bag, particularly has the compound ventilating packaging bag of a kind of plastics of airing function.
Background technology
Plastic packaging bag inevitably will enter air in packaging process, packaging bags finish seal after, these gases just remain in the packaging bag, the gas that remains in the packaging bag promptly influences a bag interior product quality guarantee period, the gas that makes packaging product remain in the bag when carrying, stacking again can produce very big pressure, thereby causes packaging bag to be broken.The interior residual gas that has of packaging bag simultaneously makes a bag type can not keep smooth and stabilized conditions, thereby influences the stacking of packaging bag.For solving the problem of gas residue in the packaging bag, Chinese patent has openly been invented a kind of one-way exhaust valve plastic packaging bag in the prior art, though this kind packaging bag has solved the problem of gas residue in the packaging bag, this packaging bag one-way exhaust valve complex structure, tooling cost height.Another kind of is that compound moulding compiled bag, though solved the ventilative problem of plastic packaging bag, causes the anti-soak properties of packaging bag to descend.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at above-mentioned technology, and the gas that provides a kind of energy of design will remain in the packaging bag is discharged, and has airing function and simple in structure, the novel compound ventilating packaging bag of a kind of plastics.
The compound ventilating packaging bag of a kind of plastics of the present utility model mainly comprises bag 1, it is characterized in that: the seam at bag 1 is compounded with a fillet nonwoven fabrics 2, is provided with countless small breather holes 3 on nonwoven fabrics 2.
The utlity model has following advantage: because the seam of bag 1 is compounded with a fillet nonwoven fabrics 2, on nonwoven fabrics 2, be provided with countless small breather holes 3, when the can article, pressure rises in the bag, gas is discharged by the breather hole on the compound nonwoven fabrics 2 of the seam of bag 13, the interior residual gas of packaging bag was discharged after the packing of product finished, can not only reduce air in the packaging bag, improve and prolong the shelf-life of product, and can also reduce breakage in carrying or packaging bag during the stacking product, the neat stacking of more convenient product, this packaging bag are specially adapted to the packaging of cereal crops such as rice.In addition the utility model packaging bag also have simple in structure, the processing and manufacturing low cost and other advantages.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the compound ventilating packaging bag scheme drawings of a kind of plastics of the utility model.
Fig. 2 is compounded with the partial enlarged drawing of a fillet nonwoven fabrics 2 for this packaging bag seam.
