Patent KR-790000157-B1 (KR)
Title: Packing method of melting-type packing sack for asphalt substance
Inventor: KIM C Y
Filed: 1978-02-22
Granted: 1979-03-22
Abstract: Polyethylene film packing sack, whose m.p. is almost the same as asphalt, was packed in a hard packing basket.  The bottom was then filled with cooling water. Hot, molten asphalt was than poured in displacing the water which was forced over the rim of the basket followed by sealing the sack.  Because the m.p. of the asphalt and PE film is almost the same the packing doesn't have to be removed prior to remelting as with paper packing.
