Dangerous Goods by Road
Bags, water resistant, 5L3: to prevent the entry of moisture the bag shall be made waterproof, for
example by the use of:
(a) separate inner liners of water resistant paper (e.g. waxed kraft paper, tarred paper or
plastics-coated kraft paper); or
(b) plastics film bonded to the inner surface of the bag; or
(c) one or more inner liners made of plastics material.
Maximum net mass: 50 kg.
Woven plastics bags
5H1 without inner liner or coating
5H2 sift-proof
5H3 water resistant
Bags shall be made from stretched tapes or monofilaments of a suitable plastics material. The strength
of the material used and the construction of the bag shall be appropriate to the capacity of the bag and
to its intended use.
If the fabric is woven flat, the bags shall be made by sewing or some other method ensuring closure of
the bottom and one side. If the fabric is tubular, the bag shall be closed by sewing, weaving or some
other equally strong method of closure.
Bags, sift-proof, 5H2: the bag shall be made sift-proof, for example by means of:
(a) paper or a plastics film bonded to the inner surface of the bag; or
(b) one or more separate inner liners made of paper or plastics material.
Bags, water resistant, 5H3: to prevent the entry of moisture, the bag shall be made waterproof, for
example by means of:
(a) separate inner liners of water resistant paper (e.g. waxed kraft paper, double-tarred kraft paper
or plastics-coated kraft paper); or
(b) plastics film bonded to the inner or outer surface of the bag; or
(c) one or more inner plastics liners.
Maximum net mass: 50 kg.
Plastics film bags
5H4
Bags shall be made of a suitable plastics material. The strength of the material used and the
construction of the bag shall be appropriate to the capacity of the bag and to its intended use. Joins and
closures shall withstand pressures and impacts liable to occur under normal conditions of carriage.
Maximum net mass: 50 kg.
Paper bags
5M1 multiwall
5M2 multiwall, water resistant
Bags shall be made of a suitable kraft paper or of an equivalent paper with at least three plies, the
middle ply of which may be net-cloth and adhesive bonding to the outer paper plies. The strength of
the paper and the construction of the bags shall be appropriate to the capacity of the bag and to its
intended use. Joins and closures shall be sift-proof.
Bags 5M2: to prevent the entry of moisture, a bag of four plies or more shall be made waterproof by
the use of either a water resistant ply as one of the two outermost plies or a water resistant barrier
made of a suitable protective material between the two outermost plies; a bag of three plies shall be
made waterproof by the use of a water resistant ply as the outermost ply. Where there is a danger of
the substance contained reacting with moisture or where it is packed damp, a waterproof ply or
barrier, such as double-tarred kraft paper, plastics-coated kraft paper, plastics film bonded to the inner
surface of the bag, or one or more inner plastics liners, shall also be placed next to the substance. Joins
and closures shall be waterproof.
Maximum net mass: 50 kg.
