                  SILGAN HOLDINGS RAISES 2004 EARNINGS OUTLOOK


STAMFORD, CT, January 11, 2005 - Silgan Holdings Inc.  (Nasdaq:SLGN),  a leading
supplier  of  consumer  goods  packaging  products,  announced  today that it is
raising its 2004 full year and fourth quarter earnings outlook to at least $4.40
and $0.76 per diluted share,  respectively,  including  rationalization charges.
The Company's  previous full year earnings  outlook had been a range of $4.06 to
$4.26 per diluted share.  Primary  contributors to this revised earnings outlook
are better than projected sales volume recorded late in the fourth quarter and a
favorable pre-tax benefit of $3 million  resulting from a litigation  settlement
reached with an equipment supplier in the last week of December.

As previously  announced,  Silgan  Holdings will release its fourth  quarter and
full year 2004 earnings  results on Thursday,  February 9, 2005,  after the U.S.
markets close. The Company will then host its earnings  conference call at 11:00
a.m. eastern time on February 10, 2005, during which the Company will discuss in
detail the  results for this period as well as provide  more  detailed  earnings
guidance for 2005.

The toll free number for domestic  callers is (800)  299-7089 and  international
callers should dial (617) 801-9714.  The pass code is 42088112. For those unable
