Abstract

A bag having walls formed at least predominantly of paper material, the paper material having been made antistatic by addition of a conductive salt, is made flame retardant at the same time if the paper material has been admixed with a flame retardant in a concentration such that the leakage resistance is <10 9 Ω.

Claims

exact text as granted — not AI-modified

1 . Bag having walls formed at least predominantly of paper material, the paper material having been made antistatic by addition of a conductive salt, characterized in that the paper material has been admixed with a flame retardant in a concentration such that the leakage resistance is &lt;10 9 Ω. 
   
   
       2 . Bag according to  claim 1 , characterized in that the flame retardant is an organic halogen salt, phosphorus salt or boron salt or a salt containing nitrogen compounds. 
   
   
       3 . Bag according to  claim 1 , characterized in that the salt is water-soluble. 
   
   
       4 . Paper bag according to  claim 2 , characterized in that the flame retardant is an alkali metal pyrophosphate, alkaline earth metal pyrophosphate or ammonium pyrophosphate. 
   
   
       5 . Bag according to  claim 1 , characterized in that the paper material has been admixed with ≧20% by weight of flame retardant.
