Abstract
A method can include consecutively batch processing at least two different polyethylene grades in pellet form in a pellet handling unit. A ratio of a melt flow index (MI) of a first polyethylene in pellet form (MI) to a MI of a later processed polyethylene in pellet form (MI) can be smaller than 0.30. The method can include processing an intermediate polyethylene grade in pellet form. An amount of intermediate polyethylene grade processed can be at most 1/100of a handling capacity of the pellet handling unit. The intermediate polyethylene grade can have the same MI as the later processed polyethylene in pellet form.
