Comparison of Returnable Paper and Plastic Corrugated Packaging Trays for the United States Postal Service
This study provides a comparison of paper and plastic corrugated materials that are used for packaging. The test containers were mail trays used by the United States Postal Service. The test methods consist of performing an accelerated test in a warehouse facility that closely simulates the everyday handling characteristics encountered by these trays in postal facilities. The results also compared differences in material-recycled content and fabrication processes. The results show that the reusable plastic corrugated trays performed 2.5 to 3 times better than similar types of reusable paper corrugated trays.
