HumusPak is a US-based startup that offers home compostable protective packaging products like air cushions and compostable mailers. The startup uses cornstarch or vegetable-based plastic, and bio-based polymer to make these packaging products, which are highly protective and cost-effective. Businesses use the startup’s lightweight packaging air cushions to improve product protection. Also, they break down into natural elements in a composting environment without leaving toxic chemicals in the soil.
