Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to the package field, especially to a package bag.

2. Description of Related Art

In the panel industry nowadays, liquid crystal glasses are usually applying horizontal stacking method to dispose in the package case, and simultaneously a pad layer is used to separate two glass panels next to each other for buffer function and prevent liquid crystal panel adhering together when taking out a liquid crystal panel.

Liquid crystal glasses have higher criteria in package materials that pads in use is free from dust, pollution or water-stains to prevent polluting or etching peripheral terminals or elements around liquid crystal glasses, so present pads are packed by applying plastics packages and then sealed by applying taps or thermo-pressing methods. However, plastics packages usually are polyethylene bags that preventing entering from dust or water stain entering from the air after sealing, but air inside and outside the bags cannot be able to ventilate to adjust the temperature and moisture inside the bags in time. After pads is packed well, surfaces of the pads inside the bags are usually having water stains to polluting or etching peripheral terminals or elements around the liquid crystal glasses due to higher temperature inside compartments after long-distance transportation.

SUMMARY

Because of existed defects of present technology, the invention provides a package bag with effects of water-proof air permeability.

To achieve the object described above, the invention employs technology hereinafter:

A package bag comprises a package bag body and at least a film, at least a through hole disposed on the top of the package bag body, and the film with waterproof air permeability is attached on a surface of the through hole.

Wherein, the package bag body is manufactured with polyethylene material.

Wherein, the film includes a first film layer, and the first film layer is made of foaming polyurethane material.

Or, the film includes a first film layer, and the first film layer is made of Polytetrafluoroethene (PTFE) material.

Wherein, the film includes more than one mentioned first film layers and a dry layer disposed between two layers of the first film layers.

Wherein, the dry layer is a moisture-proof sheet.

Or, the dry layer is active carbon.

Wherein, the film is attached on one inside surface of the package bag body.

Wherein, the film is attached on a side of the package bag body, and the area of the side is smaller than those of other sides.

The package bag of the invention has good waterproof performance and air permeability performance to keep clean and dry inside the package bag even at high temperature environment and effectively protects products inside the package bag.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 2 is the local structure of schematic view of embodiment 1 of the invention.

FIG. 3 is the local structure of schematic view of embodiment 2 of the invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

To make the objects, technical solutions and advantages of the present invention will be more clearly understood, the accompanying drawings and the following embodiments of the present invention will be described in further detail. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

Embodiment 1

Refer to FIG. 1, the invention provides a package bag, comprising a package bag body 10 and at least a film 20, at least a through hole 100 is disposed on the top of the package bag body, and the film 20 with waterproof air permeability is attached on a surface of the through hole 100.

In this embodiment, the package bag body 10 is manufactured with polyethylene material, and sealed by a tap.

As shown in FIG. 2, a package bag body is used for stacking a plurality of pads 200 to achieve waterproof air permeability of film 20, and a film 20 in this embodiment is a layer of a first film layer 21 which can be made of foaming polyurethane material or Polytetrafluoroethene (PTFE) material here and both materials are with good heat insulation and air permeability; in particular, when the first film layer 21 is made of foaming polyurethane material, which has several micro holes to achieve ventilation inside and outside the package bag, and simultaneously prevent steam and dust from entering.

The film is attached on an inner surface of the package bag body 10 to prevent steam entering the package bag when being tore open by some unusual force.

It is understandable that the amount of through hole 100 can be disposed a lot, and correspondingly the film 20 adhere to an inner surface of a corresponding through hole 100. At least a film 20 is attached on a side of the package bag body 10 at the same time, and the area of the side is smaller than those of other sides. The side is not covered when stacking multiple package bags 10 with pads 200 on the larger area, and is able to ventilate with air outside.

Embodiment 2

As FIG. 3 shows, this is the local structure of schematic view of the embodiment of the invention, and what differences from the embodiment 1 is that the film 20 includes multiple first film layers 21 and a dry layer 23 disposed between two layers of the first film layers 21 in this embodiment. Due to increasing the dry layer 23, an opening of the first film layer 21 in this embodiment is larger a little than that in the embodiment 1 to ensure air inside and outside the package bag can exchange normally. Wherein, the dry layer 23 is a moisture-proof sheet or active carbon. The dry layer 23 can also act absorbing even when little outside steam entering the film 20 by this kind of arrangement and preventing continuing entering inside of the package bag, which is with well air permeability and simultaneously preventing water stain occurrence happened inside the package bag more efficiently.

The package bag provided by the embodiment of the invention disposes a through hole 100 on a surface of the package bag body 10, a film 20 with waterproof air permeability is disposed correspondingly on the through hole 100 to prevent dust and steam outside entering to the bag, and due to the well air permeability performance of the film 20, the air inside and outside of the package bag can be exchange normally to prevent pads 200 get wet from forming vapor due to different temperatures inside and outside the package bags.

The above-described specific embodiment is only of the present invention, and it should be noted that those of ordinary skill in the art, in the present invention without departing from the principles of the premise, but also several improvements and modifications can be made, these improvements and retouching also be considered the scope of the present invention.
