US flexible packaging printing technology leads the world

The United States, in the world's soft

packaging technology development, holds a leading position, especially the country's various

packaging structures, printing methods and packaging methods are particularly distinctive. Beverage flexible packaging: as environmental requirements become increasingly strict, flexible packaging is also becoming a trend, and many new packaging structures of different types are successfully meeting the demanding freshness-preservation requirements of beverages.

The United States holds a leading position in the development of flexible packaging printing technology worldwide, layout design, especially the country's various food packaging structures, printing methods and packaging methods are particularly distinctive.

Beverage flexible packaging: as environmental requirements become increasingly strict, flexible packaging is also becoming a trend, and many new packaging structures of different types are successfully meeting the demanding freshness-preservation requirements of beverages. The printing method is gravure or flexographic printing. The packaging format is stand-up pouches, etc.

Packaging materials, structures and properties: PET/ALL/PE, suitable for various juice and other beverage stand-up

Web publishing, very good mechanical properties, suitable for heat sealing; PET/EVOH/PE, suitable for various juice and other beverage stand-up pouches, with good barrier properties and good transparency; PER/ALU/PET/PE, better heat resistance than "PER/ALU/PE"; PER/ALU/PET/PE commercial web offset in China, suitable for various non-concentrated beverages, tea and coffee and other beverage stand-up pouches, better mechanical properties than "ET/ALU/PE" (ALU is aluminum foil).

Coffee packaging: coffee is a traditional European product with a long history of packaging development. Today, packaging with various composite structures can already meet any storage and display requirements for coffee.

The printing method is gravure, up to 10 colors; the packaging format is three-side seal or four-side seal mechanism/organization, used for granular or powdered vacuum or modified atmosphere packaging.

Packaging materials, structures and properties: PER/ALU/PE, suitable for vacuum or modified atmosphere packaging pouches; OPP/ALU/PE: suitable for vacuum or modified atmosphere packaging pouches, with very good mechanical resistance and good processing performance; PET/M/PE, suitable for vacuum or modified atmosphere packaging pouches book reviews, with fairly high barrier properties when aluminum foil is not used; paper PE/ALU/PE, suitable for single-pouch vacuum or modified atmosphere packaging, convenient to eat; OPA/ALU/PE, suitable for vacuum or modified atmosphere packaging pouches, with excellent high barrier properties and mechanical resistance.

Meat product packaging: meat product packaging uses a variety of composite materials "China Printing Blue Book", to meet various different preservation and packaging processing conditions. In addition to traditional composite materials suitable for high-temperature and pasteurization sterilization, new transparent, high-barrier structures are also being continuously introduced; these structures are suitable for modified atmosphere and vacuum packaging.

The printing method is gravure or flexographic printing; the packaging formats are preformed pouches (including valve bags for ham packaging and three-side flat-seal pouches for cooked meat products) and thermoformed rollstock (used as the base and lid of trays); the packaging machine is a thermoforming machine.

Packaging materials, structures and properties: OPA/ALU/PE, suitable for pasteurization, used for ham packaging pouches; PER/ALU/PET/PE manufacturer information, suitable for cooked ham sterilization pouches; PER/ALU/PET/PP, suitable for semi-finished and cooked ham pouches, can use high-temperature sterilization; PER/ALU/PE, suitable for sliced meat packaging tray lids, etc.; PET/EVOH/PE, high barrier enterprises, suitable for ham slice vacuum packaging; PET/EVOH/PE, high barrier, suitable for ham vacuum packaging; PA/PE, thermoformable, with very good adhesion to the product. Suitable for ham packaging lids; PET/EVOH/PE financial crisis, thermoformable, good stiffness, high barrier, suitable for modified atmosphere packaging.

Frozen food packaging preservation: the most commonly used for storing perishable foods, its packaging requires simultaneously ensuring high freshness retention and product display effect.

The printing method is gravure, up to 10 colors; the packaging format is three-side seal pouches; the packaging machines are horizontal and vertical packaging machines.

Packaging materials, structures and properties: PET/PE, suitable for high-speed packaging of fruit; PET/M/PE lithographic printing, metallized laminated film, good visual effect, suitable for packaging vegetables, jam and fresh meat, etc.; PET/PE/M, similar in performance to the previous two laminated films, but with better printing results; OPP/PE/M platemaking, metallized laminated film, less affected by the environment, suitable for vegetable packaging.

Fresh jam packaging: several types of modified atmosphere packaging are commonly used in the packaging of such products, among which composite structures are suitable for heat treatment.

The printing method is gravure or flexographic printing; the packaging formats are thermoformed trays and pouches; the packaging machine is vertical.

Packaging machine packaging materials, structures and properties: PET/PP, good mechanical properties, pasteurizable general introduction, suitable for modified atmosphere packaging and pasteurized tray sealing lids, easy to tear open; PET/EVOH/PE, high gas barrier, used for tray sealing lids in modified atmosphere packaging; PET/EVOH/PE, same as the previous one printing inspection, but suitable for heat treatment; OPA/PE, very good mechanical properties, suitable for modified atmosphere packaging; OPA/PP, high transparency, suitable for heat treatment Shanghai Guanghua, suitable for modified atmosphere packaging and pasteurization.
