BS 6455:1984

This standard BS 6455:1984 Method for monitoring the levels of residual solvents in flexible packaging materials is classified in these ICS categories:

• 55.040 Packaging materials and accessories

This British Standard describes a method for monitoring the levels of certain residual volatile solvents in unprinted and gravure or flexographic printed papers, films, foils and laminates intended for packaging.

The method is suitable for monitoring the presence of at least the following solvents:

acetone	2-ethoxy-ethanol
tetrahydrofuran	isopropanol
N-propanol	isopropyl acetate
toluene	ethyl acetate
ethanol	methyl ethyl ketone (butanone)
N-propyl acetate	isobutanol

NOTE 1. Methyl ethyl ketone and tetrahydrofuran have very similar retention times and cannot be resolved by this method. However, the presence of both solvents in any one sample rarely occurs.

NOTE 2. The titles of the publications referred to in this standard are listed on the inside back cover.

Describes a method of monitoring the levels of certain residual volatile solvents in gravure or flexographic printed and unprinted papers, films, foils and laminates intended for packaging. Intended primarily for process control purposes.
