Glass substrate package

Abstract

A glass substrate package ( 1 ) in which a glass substrate ( 2 ) is packed and sealed is prepared by folding a film such as a PET film ( 3 ) which does not dirty surfaces of the glass substrate ( 2 ), inserting the glass substrate ( 2 ) into the folded portion of the PET film ( 3 ), and heat sealing three sides of the folded portion of the PET film while squeezing the air out of the folded portion so that heat-sealed portions ( 4 ) and ( 5 ) are formed. The package achieves high efficiency in transportation and storage of glass substrates (specifically, glass substrates to be used for LCDs etc.), and concurrently eliminates the need for a chemical washing process which is carried out after unpacking and before processing of each glass substrate and which uses special detergents.

1 . A package in which a glass substrate is packed and sealed, said package comprising a film which does not dirty surfaces of the glass substrate.  
   
   
       2 . A package according to  claim 1 , wherein the film is a polyethylene terephthalate film.  
   
   
       3 . A package according to  claim 1 , wherein the film is a laminated film comprising a plurality of layers.  
   
   
       4 . A package according to  claim 3 , wherein the innermost one of the layers constituting the laminated film is a polyethylene terephthalate layer.  
   
   
       5 . A package according to  claim 3  or  4 , wherein at least one of the layers constituting the laminated film has a moisture-proof property.  
   
   
       6 . A package according to  claim 5 , wherein said at least one layer having the moisture-proof property is an aluminum layer which is not the innermost layer.  
   
   
       7 . A package according to any of claims  1 - 6 , wherein an internal volume of the package has been deaerated.  
   
   
       8 . A package according to any of claims  1 - 7 , wherein the glass substrate is a glass substrate to be used for a liquid crystal display.
