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 flexible packaging

With the increasingly stringent environmental protection requirements, flexible packaging is also becoming a trend. New types of packaging with different structures 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 properties, 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 are better than “ET/ALU/PE” (ALU is aluminum foil).

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 meet the requirements for any storage and display of coffee.

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

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 preservation 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 ham packaging valve bags, cooked meat products trilateral flat sealing bags), thermoforming coils (used as the bottom and cover 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 , Cooked ham bags, can be used for high temperature sterilization; PER/ALU/PE, suitable for meat packaging tray cover, etc.; 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 most commonly used perishable foods are preserved, and their packaging requirements guarantee high preservation and product display.

The printing method is gravure, with up to 10 colors; the packaging is in the form of 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, wherein 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 sealing 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, high transparency For heat treatment, suitable for modified atmosphere packaging and pasteurization.
