Pet Food Brands Lead Metal-to-Plastic Conversion
Pet food brands are converting traditional metal cans to plastic retort formats faster than any other category, driven by consumer preference for lighter, easier-to-open packaging and brand interest in differentiated shelf presence relative to conventional metal can competitors. Sonoco Products and Silgan Holdings have both expanded pet food retort can capacity since 2023, targeting companies that want reliable barrier performance matching metal can shelf-life expectations. Smaller regional converters are following more slowly, constrained by the barrier engineering investment required for retort-grade plastic qualification, but conversion is broadening steadily each year across major markets.
