Recently, the packaging department of Shanghai Petrochemical Plastics Department adopted a reasonable standardization of material placement, scientific layout of loading positions, re-planning of pedestrian access and other measures to re-divide the functional positioning of the storage area. This plan has increased the space for on-site product placement. It also provides a safe passage for on-site personnel walking and forklift driving, and optimizes the forklift and pedestrian route in the storage area, which can effectively solve the safety hazards of product super-line placement and forklift pedestrians.
