Packaging body

Abstract

A packaging body comprising a bag body filled with a compound of the following formula (1) and further filled with an inert gas so as to occupy 80 vol % or more with respect to the total capacity of an internal space formed by the bag body.

1 . A packaging body comprising a bag body filled with a compound of the following formula (1) and further filled with an inert gas so as to occupy 80 vol % or more with respect to the total capacity of an internal space formed by the bag body: 
       
         
           
           
               
               
           
         
       
       (in the formula (1), R 1  and R 2  represent each independently an alkyl group having 1 to 8 carbon atoms or cycloalkyl group having 5 to 8 carbon atoms, R 3  represents a hydrogen atom or methyl group, and X represents a single bond, sulfur atom, oxygen atom, alkylidene group having 1 to 8 carbon atoms or cycloalkylidene group having 5 to 8 carbon atoms.). 
     
     
         2 . The packaging body according to  claim 1  wherein the bag body is made of a gas barrier wrapping material. 
     
     
         3 . The packaging body according to  claim 2  wherein the gas barrier wrapping material has an oxygen transmission rate of 200 [cm 3 ·25μm·m −2 ·day −1 ·atm −1 ] or less. 
     
     
         4 . The packaging body according to  claim 1  wherein the compound of the formula (1) is 2,4-di-t-amyl-6-[1-(3,5-di-t-amyl-2-hydroxyphenyl)ethyl]phenyl acrylate or 2-t-butyl-6-(3-t-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate. 
     
     
         5 . A method of producing a packaging body, comprising
 a filling step of filling a bag body with a compound of the following formula (1),   an introduction step of further introducing an inert gas into the bag body so that the gas occupies 80 vol % or more with respect to the total capacity of an internal space formed by the bag body: and   a sealing step of sealing the bag body obtained via the filling step and the introduction step:   
       
         
           
           
               
               
           
         
       
       (in the formula (1), R 1  and R 2  represent each independently an alkyl group having 1 to 8 carbon atoms or cycloalkyl group having 5 to 8 carbon atoms, R 3  represents a hydrogen atom or methyl group, and X represents a single bond, sulfur atom, oxygen atom, alkylidene group having 1 to 8 carbon atoms or cycloalkylidene group having 5 to 8 carbon atoms.).
