Biodegradable Non-Toxic Gel Formulation Expands Rapidly
Converters are reformulating gel pack contents away from petroleum-based gel compounds toward biodegradable non-toxic formulations that satisfy packaging waste reduction mandates expanding across the European Union and several US states covering cold-chain packaging. This reformulation requires requalifying thermal hold performance and leak resistance against pharmaceutical and food delivery brand standards, a process several converters report taking six to nine months per product line. Pelican BioThermal and Sonoco ThermoSafe have both announced completed biodegradable conversion programs covering their core cold-chain client ranges, while smaller regional converters continue testing alternative formulations to match incumbent thermal performance without raising unit costs. This dynamic also shapes the thermal insulation packaging market, valued by MMA at USD 9.8 billion in 2025 and expected to reach USD 24.3 billion by 2036.
Market Impact: adds 8% annual gel pack volume
