Please with reference to Fig. 5 and Fig. 6, packaging bag 900 is to use the sheet material 100 that comprises intermediate layer 10, skin 20 and internal layer 30 to process.
Intermediate layer 10 is with the formed sheet type rete of mixture that comprises one of them kind material of from the group that medium density polyethylene and aromatic metal quasi-polyethylene are constituted, selecting.
Medium density polyethylene has the intermediate density between the density of the density of high density polyethylene (HDPE) (hereinafter will be described) and low density polyethylene (LDPE) (hereinafter will be described); It has remarkable surface flatness, durability and moisture barrier properties comprises; And compare hot cohesiveness and cohesion with high density polyethylene (HDPE), because its fusing point is lower than the fusing point of high density polyethylene (HDPE) with brilliance.
The aromatic metal quasi-polyethylene is to use aromatic metal class catalyst (metallocene catalyst) to prepare.Identical with medium density polyethylene is; The aromatic metal quasi-polyethylene also has remarkable surface flatness, durability and moisture barrier properties comprises; And compare hot cohesiveness and cohesion with high density polyethylene (HDPE), because its fusing point is lower than the fusing point of high density polyethylene (HDPE) with brilliance.
Outer 20 are configured on the intermediate layer 10, are with comprising high density polyethylene (HDPE), low density polyethylene (LDPE) and in order to the formed sheet type rete of mixture of the antistatic agent of antistatic.
High density polyethylene (HDPE) is the hard polyethylene of preparation under lower or middle pressure, and it has remarkable moisture barrier properties comprises, and compares the hear resistance with brilliance with low density polyethylene (LDPE), because its fusing point is higher than the fusing point of low density polyethylene (LDPE).
Low density polyethylene (LDPE) is preparation and have a more low-density soft polyethylene under elevated pressures, and it has remarkable pliability, and compares with high density polyethylene (HDPE) and to have remarkable hot cohesiveness, because its fusing point is lower than the fusing point of high density polyethylene (HDPE).
Antistatic agent is used for antistatic, and it can be such as sulfonate (sulfonate), alkyl trimethyl ammonium chloride (alkyl trimethyl ammonium chloride) or alkyl dimethyl glycine betaine surfactants (surfactant) such as (alkyl dimethyl aminoacetic acid betaine).Use alkyl trimethyl ammonium chloride in the present embodiment.
In the present embodiment, be 100 parts high density polyethylene (HDPE) for weight, operating weight is the antistatic agent that 50 parts to 100 parts low density polyethylene (LDPE) and weight is 1 part to 15 parts.
Under this situation, if operating weight is less than 50 parts low density polyethylene (LDPE), then outer 20 pliability can reduce, and antistatic agent is difficult for transferring to outer 20 surface, so antistatic performance can reduce.If operating weight is greater than 100 parts low density polyethylene (LDPE), then outer 20 hear resistance can reduce, and antistatic agent can ooze out from outer 20 surface, so the surface can become sticky.
In addition, as if the antistatic agent of operating weight less than 1 part, then antistatic performance can reduce.If operating weight is greater than 15 parts antistatic agent, then antistatic agent can ooze out from outer 20 surface, so the surface can become sticky.
Internal layer 30 is configured in the below in intermediate layer 10, and is by comprising medium density polyethylene and in order to the formed sheet type rete of mixture of the intrinsic dissipative polymer of antistatic.
Intrinsic dissipative polymer is a kind of polymer with multiple functional group (functional groups), and it is normally by will (for example) metal salt compound (for example, LiN (CF 3SO 3) 2) be the compound (such as polyethylene glycol (polyethylene glycol) and polyester elastomer (polyester elastomer)) of main (ether-based) with ether, be the elastomer of main (nylon-based) with nylon or be that the elastomer of leading (urethane-based) mixes in specific ratio and processes with the urethane as cosolvent.For example, intrinsic dissipative polymer can be polyether block polyamide copolymer (polyether block polyamide copolymer).Especially, be main or be main intrinsic dissipative polymer, then can guarantee the pliability of internal layer 30 fully with the urethane if use with nylon.In the present embodiment, using with nylon is main intrinsic dissipative polymer.
In the present embodiment, be 100 parts medium density polyethylene for weight, operating weight is 10 parts to 30 parts an intrinsic dissipative polymer.Under this situation, as if the intrinsic dissipative polymer of operating weight less than 10 parts, then antistatic performance can reduce.If operating weight is greater than 30 parts intrinsic dissipative polymer, then the fundamental characteristics of internal layer 30 can reduce because of medium density polyethylene, and intrinsic dissipative polymer can transfer on the surface of internal layer 30, so the surface can become sticky.
In the present embodiment, sheet material 100 has the thickness of 40 μ m to 100 μ m.If thickness is less than 40 μ m, the durable of sheet material 100 then, thereby be not suitable for being used for making the packaging bag 900 of accommodating liquid crystal display device module L.If thickness is greater than 100 μ m, then the manufacturing cost of sheet material 100 is high, and can on the polarizing coating of the liquid crystal display device module L that is accommodated, form indenture.

The mixture of fusing is mixed respectively; And interconnect quilt while and co-extrusion extrusion next (coextruded) continuously three ring moulds (triple annular die) that form from first extruder, second extruder and the 3rd extruder, thereby squeeze out tubular type (tube-type) sheet material that intermediate layer 10, skin 20 and internal layer 30 pile up each other continuously.
The tubular type sheet material that utilizes so-called blowing method (blowing method) to make to squeeze out expands and cooling, thereby makes it to have thickness and the width of wanting.
Cooled sheet material is cut into suitable size, thereby accomplishes the manufacturing of the sheet material 100 be used for packing liquid crystal display device module L.
Because internal layer 30 is to be used for the mixture of intrinsic dissipative polymer of antistatic and to form by comprising, so sheet material 100 can keep the electrostatic-proof function long period.What be different from traditional sheet material 1 (being coated with antistatic backing 6 on it) is even that when internal layer 30 Long contact time liquid crystal display device module L, intrinsic dissipative polymer can not transferred on the liquid crystal display device module L yet.
Therefore; What be different from traditional sheet material 1 is; Tradition sheet material 1 must be made extra diaphragm 8 and diaphragm 8 is attached on the liquid crystal display device module L; Use sheet material 100 then to need not when packing and transfer liquid crystal display device module L, to be attached to diaphragm 8 on the liquid crystal display device module L and, therefore can to reduce the cost of packing liquid crystal display device module L, reduce the process of packing liquid crystal display device module L from liquid crystal display device module L removal diaphragm 8.
In addition, if sheet material 100 is carried out heat seal, then can be made into the packaging bag 900 that is used for accommodating liquid crystal display device module L.Fig. 6 is shown as an instance of packaging bag 900.In sheet material 100; Because outer 20 comprise that high density polyethylene (HDPE) and internal layer 30 that hear resistance is higher comprise the medium density polyethylene that hear resistance is lower; So when heat seal is carried out in packaging bag 900; Face-to-face and two internal layers 30 of configuration cohere easily each other, and two skins 20 of contact external heat are difficult for fusing.
In addition, in sheet material 100, because internal layer 30 is to be formed by the mixture that comprises medium density polyethylene, so internal layer 30 can have remarkable surface flatness.Thus, liquid crystal display device module L is easier to put into packaging bag 900 or takes out from packaging bag 900.
In addition; What be different from traditional sheet material 1 (it comprises with the formed PET film 2 of hard material) is; Because sheet material 100 comprises with formed intermediate layer 10, outer 20 of softer polyethylene and internal layer 30; Even so be housed in large-sized packaging bag 900 and the edge of packaging bag as shown in Figure 4 900 when being folded as undersized liquid crystal display device module L, the edge of packaging bag 900 can not form indenture yet on the polarizing coating of liquid crystal display device module L.
According to the present invention; Owing to be used for packing the internal layer of the sheet material of liquid crystal display device module and be by comprising medium density polyethylene and forming in order to the mixture of the intrinsic dissipative polymer of antistatic; So internal layer can have remarkable surface flatness, even and when internal layer contacts liquid crystal display device module intrinsic dissipative polymer can not transfer on the liquid crystal display device module yet.
Though the present invention discloses as above with preferred embodiment; Yet any professional and technical personnel of being familiar with should be understood that; In not breaking away from technical scheme scope of the present invention; When making a little change or modification aspect form and the details, technical scheme scope of the present invention ought look claims and the equivalent variations person of defining is as the criterion.
