Abstract

PURPOSE: To prepare deodorized pellets of ethylene polymer suitable for food packaging use, by exposing raw ethylene polymer pellets to an odorless inert gas stream of a specific flow rate for a specific time.
CONSTITUTION: Ethylene polymer pellets are charged in a semi-closed vessel such as silo, and deodorized by treating with an odorless inert gas such as N2 and air under the condition given below: The flow rate of the gas <1000m3/T.Hr; and the temperature, the gas flow rate, and the treating time satisfy the formula [wherein t is treating time (Hr), W is gas flow rate per unit wt. of pellet (m3/T.Hr), T is temperature of gas (°K) and R is gas constant, i.e. 1.987Cal/mol.°K]
