U.S. centralized packaging new technology

The United States is in a leading position in the development of the world's flexible packaging printing technology, especially the packaging structure, printing methods and packaging methods of various food packaging in the country, and it is unique.

Beverage soft packaging With the increasingly stringent environmental protection requirements, flexible packaging is also becoming a trend, and new types of packaging with different structures are successfully meeting the demanding requirements for 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. Packing bag, good barrier property, good transparency; PER/ALU/PET/PE, better heat resistance than “PER/ALU/PE”; PER/ALU/PET/PE, suitable for all kinds of non-concentrated beverages, tea Beverage vertical bags, such as coffee, have better mechanical properties than "ET/ALU/PE" (ALU is aluminum foil).

Coffee packaging Coffee is a traditional European product. Its packaging has a long history of development. Nowadays, the packaging of various composite structures can meet the requirements for any 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: PER/ALU/PE, suitable for vacuum or modified atmosphere packaging bags; OPP/ALU/PE: suitable for vacuum or modified atmosphere packaging 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 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, used in ham packaging bags; PER/ALU/PET/PE, suitable for cooked ham sterilization bags; PER/ALU/PET/PP, suitable for semi-finished products Ham bag can be used for high temperature sterilization; PER/ALU/PE, suitable for meat packaging tray cover; PET/EVOH/PE, high barrier property, suitable for ham vacuum packaging; PET/EVOH/PE, high barrier property , suitable for ham vacuum packaging; PA/PE, thermoformable, with excellent adhesion to the product. Suitable for ham packaging cap; PET/EVOH/PE, thermoformable, good stiffness, high barrier property, suitable for modified atmosphere packaging.

Frozen food packaging The preservation of perishable foods is the most commonly used and its 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 modified atmosphere packages are commonly used in the packaging of such products, where the composite structure is 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/PE, 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.
