Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to the package field, especially to a
package bag.
[0003] 2. Description of Related Art
[0004] 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.
[0005] 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.

BRIEF DESCRIPTION OF THE DRAWING
[0018] FIG. 1 is a structural schematic view of a package bag of
the invention.
[0019] FIG. 2 is the local structure of schematic view of
embodiment 1 of the invention.
[0020] FIG. 3 is the local structure of schematic view of
embodiment 2 of the invention.
DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] 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
[0022] 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.
[0023] In this embodiment, the package bag body 10 is manufactured
with polyethylene material, and sealed by a tap.
[0024] 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.
[0025] 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.
[0026] 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
[0027] 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.
[0028] 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.
[0029] 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.
