New American Food Packaging

The packaging structure, printing methods and packaging methods of several food packaging in the United States have certain unique features.

Meat Packaging US meat packaging uses a variety of composite materials to meet a variety of different packaging processing conditions and storage and transportation environment. In addition to traditional composite packaging materials for high temperature and pasteurization, new transparent, high barrier composite packaging materials are also being introduced. These composite packaging structures are particularly suitable for modified atmosphere packaging and vacuum packaging.

There are two types of packaging: one is a pre-formed bag, which includes a valve bag for ham packaging, a three-side flat sealing bag for cooked meat products, and a second hot-formed coil for use as the bottom and lid of a packaging tray.

U.S. meat composite packaging materials are usually PA/PE, OPA/ALU/PE, PET/ALU/PE, PA/EVOH/PE, PET/EVOH/PE, PET/ALU/PET/PE, PET/ALU/PET/ PP, PVE/EVOH/PE and so on. Among them, the composite packaging OPA/ALU/PE is suitable for pasteurization and is mainly used for ham packaging bags; PET/ALU/PET/PE is suitable for disinfection of cooked ham for ham packaging bags; PET/ALU/PET/PP is suitable for Semi-finished and cooked ham packaging bags can be sterilized by high temperature; PET/ALU/PE has good processing performance, suitable for packaging trays of semi-finished meat slices, etc.; PA/EVOH/PE has high barrier property, good physical and chemical properties, and is suitable for vacuum packaging of ham slices. Composite packaging PET/EVOH/PE has high barrier property, suitable for ham vacuum packaging; PA/PE composite packaging material can be thermoformed, has excellent adhesion with the product, suitable for ham packaging, etc.; FVE/EVOH/PE can be Thermoforming, good stiffness, high barrier properties, suitable for gas withered packaging. The above-mentioned printing method for composite packaging of meat products is gravure printing or flexo printing, and the color printing effect is very good.

Frozen foods are packaged in the United States, and perishable foods are often frozen and packaged. Their packaging requirements can both ensure freshness and at the same time maintain shelf display of the product to promote sales. Packaging machines use horizontal or vertical packaging machines.

In order to visually demonstrate the quality and shape of packaged products, frozen packaging materials most commonly used in frozen foods in the United States are mainly aluminum (M) composite packaging materials. Because of its good visual effects, the packaging form is three-side sealed bags, which can increase the cost-effectiveness of products. They are PET/M/PE, PET/PK/M, OPP/PE/M, and PET/PE. Among them, PET/M/Pi, aluminized composite packaging material is suitable for packaging of vegetables, jams and fresh meat; PET/PE/M is similar to the former composite film in performance, but the printing effect is better; OPP/PE/M aluminum composite coating The membrane is less affected by the environment and is suitable for vegetable packaging. PET/PE is suitable for high-speed packaging of fruits. Aluminized composite packaging printing method for gravure printing, color up to 10 colors, color printing effect is good.
