Problems solved by technology
However, there is a problem as follows: due to changes in temperature and humidity conditions during transportation or storage, dew condensation occurs on the display screen, resulting in adhesion between the display screen and the surface protection coating material, and the adhesion part will be damaged. The wet state continues due to the accumulation of water vapor, and as a result, changes in the optical color tone of the display screen, etc.

Embodiment 1
[0119] A bag was produced using the film A as the front side film and the film A as the back side film. Using a bag making machine, two pieces of roll-shaped film with a width of 350 mm are stacked and continuously drawn out, and their inner surface layers are respectively used as inner surfaces, and one side in the length direction and 2 sides in the width direction are sealed by a pulse heat sealer. The sides were sealed (thermally fused), and cut to a length of 220 mm to obtain a 350 mm×220 mm packaging bag with an opening on one side.
Embodiment 2
[0121] A packaging bag having an opening on one side of 350 mm×220 mm was formed in the same manner as in Example 1 except that the film B was used as the front side film and the film B was used as the back side film.
Embodiment 3
[0123] A 350 mm×220 mm packaging bag having an opening on one side was formed in the same manner as in Example 1 except that the film C was used as the front side film and the film C was used as the back side film.

Abstract
To prevent a surface-protecting cover material and a display screen of a liquid crystal module from coming into close contact and allowing a liquid crystal module to be packaged all the more readily. Proposed is an anti-static packaging bag for liquid crystal module, which is a bag constituted from a front film portion and a back film portion and having an open portion and a closed portion, at least the front film portion containing an anti-static agent and at least the inner surface that is to be the inside of the bag being an irregular surface.
Description
technical field [0001] The invention relates to an antistatic packaging bag used for packaging liquid crystal modules of computers, televisions, etc., and a packaging method of the liquid crystal modules. Background technique [0002] In order to prevent the liquid crystal modules of computers, TVs, etc. from attaching to garbage, dust, etc., or being damaged or polluted when they are shipped from the factory, the display screen is covered with a surface protection coating material, and then the entire liquid crystal module is stored in a plastic film Bags, and fixed with protective materials such as expanded styrene, corrugated paper, etc., and then packed and shipped. [0003] The main function of the surface protection coating material is to prevent garbage, dust, etc. from adhering to the display screen, and at the same time prevent the display screen from being damaged. However, there is a problem as follows: due to changes in temperature and humidity conditions during...
