Sonoco-Alcore to Increase European, U.K. Paperboard Prices

Sonoco-Alcore S.a.r.l. today announced it will raise prices by 40
Euro per metric ton on all paperboard grades in continental Europe. In
addition, the Company will raise prices by 10 GBP per metric ton on
all paperboard grades in the United Kingdom. Both price changes are
effective with shipments on or after May 1, 2008. The increase in the
United Kingdom is in addition to a 25 GBP per metric ton price
increase that went into effect on January 28, 2008.

According to Eddie L. Smith, Sonoco, vice president--Industrial
and Consumer Products, Europe, "Every effort has been made to manage
costs in our paper mills operations, however, rapid increases in the
cost of energy, chemicals, starch and transportation make it necessary
for us to recover these inflationary expenses."

Sonoco-Alcore S.a.r.l. is wholly-owned by Sonoco (NYSE:SON) and
operates 30 tube and core plants and six paper mills on the European
continent and in the United Kingdom.
