WATER-TIGHT PAPER CANS

To make an all-paper can water-tight, submerge it in molten paraffine, or pour hot paraffine in and out of the can. Paper, paraffined on one side, may be run on the inside or on the outside of the can, or both, to produce a moisture-proof container which will hold semi-liquids for an indefinite time.

Some paper cans have slip-on covers and bottoms, others have the top and bottom crimped on; others still have a neck for the lid. Expensive types of paper cans have spun-on ends, and many are made with screw-on tin tops.

When printed or lithographed wrappers are carefully applied to the paper cans, they cannot be told from regular tin cans. Many wrappers for paper cans are done in beautiful colors.
