ROI Calculation Logic

Assuming 1,000 wrap operations per day at a large food processing plant or logistics hub, this technology could reduce an average of 5 seconds of additional work per operation due to unrolling. This translates to approximately 347 hours of annual labor efficiency improvement. At an estimated labor cost of $13.50/hour (AI est.), this could save ~$4.5K/year (AI est.) in personnel costs. Additionally, a 5% reduction in wrap material waste (from an annual spend of ~$65K on wrap materials (AI est.)) could yield ~$3.5K/year (AI est.) in material savings. The total potential cost reduction could be ~$8K/year (AI est.).

Speed to Market
4× faster than in-house development
This technology applies the established physical phenomenon of triboelectric charging, with its basic principles clearly defined. The detailed operational mechanism is described in the patent specification, eliminating the need for licensees to conduct research and development from scratch. Its simple structure, designed for attachment to existing wrap cartons, could significantly shorten the time from prototyping to mass production. This offers an estimated 1.5-year reduction in market entry time compared to in-house development.
