The world's leading position in the US Flexible Packaging Technology Development Division
The United States is in a leading position in the development of the world's flexible packaging printing technology, especially in the country's various food packaging packaging structure, printing methods and packaging methods, it is unique.
Beverage soft packaging
As environmental protection requirements become more stringent, flexible packaging is becoming a trend, and new packaging of various structures is successfully meeting the demanding requirements of beverages. The printing method is gravure or flexo. The package is in the form of a vertical bag or the like.

Packaging materials, structure and characteristics: PET/ALL/PE, suitable for vertical beverage bags such as juices, with good mechanical properties, suitable for heat sealing; PET/EVOH/PE, suitable for beverages and other vertical beverages Packaging bag, good barrier property and good transparency; PER/ALU/PET/PE, better heat resistance than "PER/ALU/PE"; PER/ALU/PET/PE, suitable for various non-concentrated beverages, tea Vertical packaging bags for beverages such as coffee, which have better mechanical properties than "ET/ALU/PE" (ALU is aluminum foil).
Coffee is a traditional product in Europe. Its packaging has a long history of development. Nowadays, the packaging of various composite structures can meet the requirements of any storage and display of coffee.
The printing method is gravure printing, up to 10 colors; the packaging form is three-side seal or four-side seal, 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, good processing performance; PET/M /PE, suitable for vacuum or modified atmosphere packaging bags, barrier properties are not high when aluminum foil is not used; 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 bag, high barrier and excellent mechanical resistance.
Meat products are packaged in a variety of composite materials to meet a variety of storage and packaging processing conditions. In addition to the traditional composite materials for high temperature and pasteurization, new structures with transparent and high barrier properties are also being introduced. These structures are suitable for air conditioning and vacuum packaging.
The printing method is gravure or flexo printing; the packaging form is pre-formed bag (including valve bag for ham packaging, three-side flat bag for cooked meat products), thermoformed roll (used as bottom and cover for tray); packaging machine is Thermoforming machine.
Packaging materials, structure and characteristics: OPA/ALU/PE, pasteurized for ham bags; PER/ALU/PET/PE, suitable for cooked ham sterilized bags; PER/ALU/PET/PP, suitable for semi-finished products Cooked 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 vacuum packaging of ham slices; PET/EVOH/PE, high barrier property It is suitable for vacuum packaging of ham; PA/PE, it can be thermoformed, and the adhesion with the product is very good. Applicable to ham packaging cover; PET / EVOH / PE, can be thermoformed, good stiffness, high barrier properties, suitable for modified atmosphere packaging.
Frozen food packaging
Preservation of perishable foods is common, and its packaging requirements ensure high preservation and product display effects.
The printing method is gravure printing, up to 10 colors; the packaging form is a three-side sealing 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, aluminized composite film, good visual effect, suitable for packaging of vegetables, jams and fresh meat; PET/PE/M, It has similar performance to the first two composite membranes, but the printing effect is better; OPP/PE/M, aluminized composite membrane, which is less affected by the environment, is suitable for vegetable packaging.
Fresh jam packaging
Several modified atmosphere packagings are commonly used in the packaging of such products, wherein the composite structure is suitable for heat treatment.
The printing method is gravure or flexo printing; the packaging form is thermoformed disc, bag; the packaging machine is vertical.
Packaging machine packaging materials, structure and characteristics: PET / PP, good mechanical properties, pasteurization, suitable for modified packaging and pasteurized tray closure, easy to tear; PET / EVOH / PE, high gas barrier The tray sealing cover PET/EVOH/PE for modified atmosphere packaging is the same as the former, but suitable for heat treatment; OPA/PE, very good mechanical properties, suitable for modified atmosphere packaging; OPA/PP, high transparency Suitable for heat treatment, suitable for modified atmosphere packaging and pasteurization.
