Case of Collaborative Packaging of Stretch Film and Paper Corner Protectors: Optimization Practice of Home Appliance Warehousing and Logistics

A certain home appliance manufacturing enterprise is confronted with two major problems in the finished product warehousing process: the bottom of the cartons deforms after being stacked more than three layers, and the corners are damaged due to manual handling during loading and unloading. The overall damage rate of the goods reaches 4%.

Solution: Composite unitized packaging system

The enterprise implements a combined plan on the automated packaging line

Bottom reinforcement: L-shaped paper corner protectors (50×50mm) are installed on the eight edges of the bottom cartons of all pallets to form an anti-pressure framework.

Overall fixation: Use a pre-stretching wrapping machine (in conjunction with 20-micron machine film) to systematically wrap the entire palletized goods that have completed the corner protection installation.

Layered protection: Add horizontal paper corner protectors between every two layers of cartons to distribute the stacking pressure.

Implementation effect and key data.

Stacking safety breakthrough: The number of stacking layers has been increased from 3 to 5, and the vertical space utilization rate of the warehouse has risen by 40%.

The rate of transportation damage has sharply declined: The rate of corner damage during outbound loading and trunk transportation has dropped from 4% to less than 0.5%.

Improved loading and unloading efficiency: Standard unitized packaging has increased forklift operation efficiency by 50% and reduced loading time by 35%.

Comprehensive cost optimization: Despite the increase in initial investment, the reduction in cargo damage and the improvement in efficiency have led to a 18% decrease in the annual total logistics cost.

This case demonstrates that the systematic combined application of stretch film and paper corner protectors can achieve a full-chain protection upgrade from warehousing to transportation, and is an effective solution to deal with the high-intensity working environment of modern logistics.
