FORT WAYNE, IND. — Aunt Millie’s, a family-owned bakery company, has made the inner wrap on its Aunt Millie’s Hearth Breads degradable. The change will affect 12 bread varieties.

In December, the company said it converted the inner wrap for all its Hearth Breads to EnviroSafe 502E degradable OPP film, which decomposes completely into CO2 and biomass over time when exposed to sunlight, moisture and heat.

“Degradable inner wrap costs 50% more than non-degradable film, but we thought it was worth it for the sake of the environment,” said Melissa Dunning, marketing director for Aunt Millie’s. “Aunt Millie’s wants to lead the way in sustainable bread packaging.”

Ms. Dunning said there will not be an increase in the suggested retail price of the bread.

The outer bags of all Aunt Millie’s bread varieties are made with No. 4 LDPE plastic, which is recyclable, but not accepted for recycling in all areas.
