Biodegradable Packaging Films with Shelf Life in Local Food Markets: Optimization Modeling

Abstract

The transition toward sustainable food supply chains necessitates the replacement of conventional petroleum-based plastics with biodegradable packaging films. However, the adoption of these sustainable alternatives in local food markets is often hindered by uncertainties regarding their impact on shelf life and overall economic viability. This paper presents a comprehensive optimization modeling approach designed to balance the material properties of biodegradable packaging films with the shelf life requirements of fresh produce in local market settings. By conceptualizing a multi-objective framework, the study evaluates the oxygen transmission rates, water vapor permeability, and mechanical strength of various biopolymers against the respiration rates and spoilage kinetics of highly perishable goods. The proposed model seeks to minimize packaging costs and food waste while maximizing the effective shelf life under variable ambient conditions typical of local agricultural markets. Through extensive simulated case studies focusing on specific produce categories, the analysis demonstrates that optimized biodegradable packaging configurations can achieve shelf life extensions comparable to conventional plastics, resulting in significant reductions in aggregate supply chain waste. The findings provide a theoretical foundation and practical guidelines for local producers and distributors to select appropriate biodegradable materials that align with both environmental sustainability goals and economic constraints.
