From airtight wraps to shelf stable bottles and containers, plastic packaging plays a key role in delivering a safe food supply, from farm to table and is a material of choice for freezing foods for longer term storage.

Plastics have also driven innovations in packaging design. For example, modified atmosphere packaging helps preserve food freshness by capturing a reduced-oxygen air mixture in a plastic package. This technique can extend a product’s shelf life by slowing the growth of bacteria.

In the United States, the Food and Drug Administration regulates the safety of food-contact packaging, including plastics used in contact with food.

Many plastics, such as polystyrene and polyethylene, have been used in food packaging for decades.

All food-contact packaging materials must pass FDA’s stringent approval process—the agency must find them safe for use in a specific packaging application—before they can be put on the market.

INOX tunnels handle plastic packaging for food products in all shapes and sizes.

Controlled product infeed and outfeed marshaling ensure that all surfaces of the packaging are contacted by the cooling medium throughout the tunnel length to ensure the effective temperature change required.
