The invention relates to a distributor, which comprises a shell which is internally provided with a main runner and at least a subrunner; and each subrunner is respectively communicated with the main runner. The distributor is characterized in that the intersection of the main runner and the subrunner are removably provided with a diversion part. The diversion part of the distributor can be replaced according to the requirement, thus realizing the manufacture of laminated plastic packing material in the thickness direction and multicolor plastic packing material formed by various materials with different colors on one extrusion molding equipment; the replacement process of the diversion part is simple and fast, spends shorter time and does not affect the normal proceeding of the manufacture; the expense of providing various diversion parts is lower; a plastic packing product manufacture can achieve the purpose of manufacturing various plastic packing materials on one extrusion moldingequipment by only adding minimal investment. The distributor can be used for the manufacture of different sheets by simple and rapid replacement or adjustment, thus greatly increasing the utilizationfactor of the device.
