                        SPARTECH CORPORATION ANNOUNCES

                 FIRST QUARTER FISCAL 2005 SALES AND EARNINGS


     ST. LOUIS, March 8, 2005 - Spartech Corporation (NYSE:SEH) announced
today sales and earnings for its first quarter ended January 29, 2005.

     Spartech's Chairman, President and CEO, Bradley B. Buechler, reported
that sales for the first three months of fiscal 2005 were $304.5 million, a
26% increase (representing 3% internal growth, 10% from acquisitions, and 13%
from price/mix) compared to the Company's first quarter sales last year of
$241.5 million.  However, the Company's fiscal 2005 first quarter operating
earnings were $10.3 million or 45% lower than the $18.8 million reported for
the same quarter la
st year.  These sales and operating results produced first quarter net
earnings of $2.8 million or $.09 per diluted share (in line with our early
February 2005 guidance for the quarter), compared to $7.7 million, or $.26
per diluted share generated in last year's first quarter.

     Commenting on the results, Mr. Buechler stated, "Spartech's first
quarter proved to be a very difficult one.  Record high resin prices,
combined with increases in several conversion cost components, including
labor, freight, and utilities, resulted in severe downward pressure on our
margins.  Based on these unacceptable results, we implemented several
operational changes, involving the closing of certain plants and the
planned disposal of two non-core operations.  We estimate that the
implementation of these actions will cost $5-6 million over the second and
third quarters of fiscal 2005, but going forward, will eliminate an
estimated $9 million of annual pre-tax expenses. The estimated costs will
include asset write-downs, severance, moving, and lease buy-out expenses
..with two-thirds of these expected to be non-cash expenditures."

SEGMENT RESULTS
  Custom Sheet & Rollstock - Net sales in our Custom Sheet & Rollstock
  segment were $189.6 million in the first quarter of fiscal 2005, an
  increase of 22% from the $155.4 million produced in the same three month
  period of 2004.  This sales increase was attributable to our late fiscal
  2004 acquisition of VPI (7%) and the impact of price/mix changes (16%)
  being partially affected by a 1% decline in internal volume (pounds
  sold).  This slight decrease in internal volume was primarily the result
  of slowdowns in the group's Building & Construction and Pool & Spa
  markets.  The segment's operating earnings declined by 47% due to sharp
  raw material price increases and greater than normal freight, utility
  and start-up costs of our recently expanded Donchery, France facility.

  Color & Specialty Compounds - The Company's Color & Specialty Compounds
  group saw its sales increase sharply to $97.1 million or 36% greater
  than last year's $71.3 million.   Approximately 20% of this increase was
  the result of the Company's VPI acquisition, with 9% driven by price/mix
  changes, and the remaining 7% from strong internal growth, principally
  in the Lawn & Garden and Transportation markets.  However, operating
  earnings declined by about 8% due once again to persistently high resin
  prices, coupled with excess conversion costs resulting from high energy-
  related expenses and lingering start-up costs in the group's expanded
  facility in France.

  Molded & Profile Products - Our Molded & Profile Products segment
  produced a 20% increase in first quarter 2005 sales - from $14.8 million
  last year to $17.8 million this year. New customers, added by the wheels
  unit, along with strong sales into the marine market produced the bulk
  of this increase.  However, operating earnings for the group declined by
  nearly 50% in the first quarter, related to product mix changes and
  start-up costs associated with the ramp-up of new production capacity at
  our Tupelo, Mississippi, facility.

          Earnings

     Finally, Mr. Buechler stated,  "As we move forward into our second
quarter, we are seeing some mixed economic signals from the various markets
we serve - packaging remains strong, while building & construction and
transportation are showing some weakness.  Therefore, we will expeditiously
move forward with the plant restructuring program we announced on February
9, and will diligently monitor all costs throughout our operations as we
move toward a more globally competitive company in the years ahead.  In
addition, we remain committed to expanding our raw material sourcing
horizons to give us some relief on the persistently high prices for our raw
materials in an effort to better serve our growing customer base.
Considering all of the above, and assuming no significant deterioration in
the overall economic environment, we believe our best guidance for full
fiscal year 2005 diluted earnings per share is $1.30 to $1.40."

* Our effective tax rate decreased from 38.2% in the first quarter of 2004
to 26.0% in the first quarter of 2005.  This decrease reflects a reduction
in deferred tax liabilities associated with implementation of state tax
planning strategies that will reduce our long-term effective tax rate,
relative to low earnings before income taxes.  We estimate that our
effective tax rate will approximate 37% for the remainder of fiscal 2005
resulting in an approximate 36% effective tax rate for the fiscal year.
