Bags, sift-proof, 5L2: the bag shall be made sift-proof, for example by the use of:
(a) paper bonded to the inner surface of the bag by a water resistant adhesive such as bitumen; or
(b) plastics film bonded to the inner surface of the bag; or
(c) one or more inner liners made of paper or plastics material.
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
