                      SILGAN HOLDINGS ANNOUNCES ACQUISITION
                        OF CANADIAN PLASTIC BLOW MOLDER,

supplier of consumer goods packaging  products,  announced today the acquisition
of substantially all of the assets of Cousins-Currie Limited, a leading Canadian
blow molder of custom designed large-ware plastic bottles.  The business,  which
had sales of approximately CAD $55 million (or approximately US $48.4 million at
current  exchange  rates) for the latest  twelve  months,  is  headquartered  in
Woodbridge,  Ontario.  The  purchase  price of CAD $48.3  million  was  financed
primarily  with  Canadian  dollar  borrowings  under the  Company's  bank credit

the 50  best-managed  companies in Canada for the last three years as determined
by an independent study. Combined with Silgan's existing plastics business, this
transaction creates a market leading competitive  position for our custom bottle
franchise in Canada," Mr. Lewis concluded.
