U.S. Flexible Packaging Technology World Class

The United States is in a leading position in the development of flexible packaging technology in the world. In particular, the packaging structure, printing methods and packaging methods of various food packaging in the region have a de facto reference value for food production and packaging companies in China.

Soft drink packaging. With the increasingly stringent environmental protection requirements, flexible packaging is also becoming a trend, and a variety of different types of new packaging are successfully meeting the stringent preservation requirements of beverages.

The printing method is gravure or flexo. The packaging is in vertical bags.

Packing material, structure and characteristics: PET/ALL/PE, suitable for vertical packaging bags of various fruit juices, etc. It has excellent mechanical properties and is suitable for heat sealing; PET/EVOH/PE, suitable for various fruit juices, etc. Packaging bag, good barrier property, good transparency; PET/ALU/OPA/PE, better heat resistance than PET/ALU/PE; PET/ALU/PET/PE, applicable to all kinds of non-concentrated beverages, tea Beverage vertical bags such as coffee are better than ET/ALU/PE. (Note: ALU is aluminum foil, the same below).

Coffee packaging. Coffee is a traditional product of Europe. Its packaging has a long history of development. Nowadays, the packaging of various composite structures can satisfy any requirements for the storage and display of coffee.

The printing method is gravure printing, with up to 10 colors; the packaging is in the form of a three-side seal or a four-side seal, and is used for granular or powdery vacuum or modified atmosphere packaging.

Packaging materials, structure and characteristics: PET/ALU/PE, suitable for vacuum or modified atmosphere packaging bags; OPP/ALU/PE: suitable for vacuum or modified atmosphere bags, excellent mechanical resistance, and good processing performance; PET/M /PE, suitable for vacuum or modified atmosphere packaging bag, without barrier when the aluminum foil is quite high; paper PE/ALU/PE, suitable for single bag vacuum or modified atmosphere packaging, easy to eat; OPA/ALU/PE, suitable for Vacuum or modified atmosphere bags have excellent barrier properties and mechanical resistance.

Meat product packaging. Meat packaging uses a variety of composite materials to meet a variety of different storage and packaging processing conditions. In addition to the traditional composite materials for high-temperature and bar-type disinfection, new transparent, high-barrier structures are also being introduced. These structures are suitable for air-conditioning and vacuum packaging.

The printing method is gravure printing or flexo printing; the packaging forms are pre-formed bags (including valve bags for ham packaging, three-side flat sealing bags for cooked meat products), thermoformed coils (used as the bottom and lid of the tray); the packaging machine is Thermoforming machine.

Packaging materials, structure and characteristics: OPA/ALU/PE, suitable for pasteurization, for ham bags; PER/ALU/PET/PE, suitable for cooked ham sterilization bags; PET/ALU/PET/PP, suitable for semi-finished products Cooked ham bags can be used for high temperature sterilization; PET/ALU/PE, suitable for meat packaging tray cover, etc.; PA/EVOH/PE, high barrier property, suitable for vacuum packaging of ham slices; PET/EVOH/PE, high barrier property , suitable for ham vacuum packaging; PA/PE, thermoformable, with excellent adhesion to the product. Suitable for ham packaging caps; PVE/EVOH/PE, thermoformable, good stiffness, high barrier properties, suitable for modified atmosphere packaging.

Frozen food packaging. Perishable foods are the most commonly used, and their packaging requirements guarantee high preservation and product display.

The printing method is gravure, with up to 10 colors; the packaging is a three-sided sealed bag; the packaging machine is a horizontal and vertical packaging machine.

Packaging materials, structure and characteristics: PET/PE, suitable for high-speed packaging of fruits; PET/M/PE, aluminum composite film, good visual effect, suitable for packaging of vegetables, jams and fresh meat; PET/PE/M, The performance is similar to that of the former two composite films, but the printing effect is better; OPP/PE/M, aluminized composite film, is less affected by the environment and is suitable for vegetable packaging.

Fresh jam packaging. Several types of modified atmosphere packaging are commonly used in the packaging of such products, and the composite structure should be suitable for heat treatment.

The printing method is gravure printing or flexo printing; the packaging forms are thermoformed disks and bags; the packaging machine is vertical.

Packaging machine packaging materials, structure and characteristics: PET / PP, good mechanical properties, pasteurization, suitable for atmosphere packaging and pasteurization of the tray sealing lid, easy to tear; PET / EVOH / PE, high gas barrier , Pallet closure cap for modified atmosphere packaging; PET/EVOH/PP, same as the previous one, but suitable for heat treatment; OPA/PE, very good mechanical properties, suitable for modified atmosphere packaging; OPA/PP, transparency High, suitable for heat treatment, suitable for modified atmosphere packaging and pasteurization.
