Biodegradable Packaging Materials for F&B Industry

Insulated food containers that preserve food quality, stack well, have audible snap closures, and are compostable. The containers have a base and cover that snap together with protrusions and recesses. The base and cover have angled sides that form an interference fit. When the cover is removed, the interference snaps the protrusions into the recesses with an audible snap. The containers are insulating, stackable, and made from compostable materials. The containers can be used for transporting and cooking food without sogginess or leaks.

Method for producing biodegradable and compostable containers and packaging using agricultural and food waste as starting material. The method involves mixing the waste with a plasticizer, hydrothermal treatment to modify the components, and thermoforming to shape the material into containers. The resulting containers have high biodegradability and compostability due to using waste with specific fiber, lipid, protein, and carbohydrate content ranges. The method enables sustainable production of biodegradable packaging without additional waste or emissions.

Fully biodegradable and compostable product packaging that reduces waste sent to landfills and has a lower environmental impact compared to traditional packaging. The packaging is made entirely of biodegradable, compostable, and recyclable materials. It includes a biodegradable box, biodegradable filler material, biodegradable product, and biodegradable adhesive. The packaging can be fully biodegraded and composted, unlike conventional packaging which often contains non-biodegradable materials. The use of biodegradable components allows the entire packaging assembly to be biodegraded and composted, reducing waste in landfills. The biodegradable adhesive used to join the box panels is also biodegradable. The filler material, product, and adhesive all break down naturally.
