A good packaging, can play the role of icing on the cake, so people pay more and more attention to packaging. In recent years, three-dimensional aluminum foil bag with its excellent performance, into people's vision, become the topic of food packaging discussion center.
Basic information
Aluminum foil three-dimensional bag refers to a composite bag containing aluminum foil, according to the unique properties of aluminum with other high barrier materials after dry composite aluminum foil bag products. The main film substrates of composite bag are: outer printable film BOPA BOPET BOPP inner heat-sealing film CPP PE, and co-extrusion film. AL (aluminum foil) is also one of them, usually as an intermediate layer of these materials according to the requirements, by glue composite film.
Aluminum foil three-dimensional bag common structure: PET/PA/PE or CPP PET/AL/CPP PA/AL/CPP PET/PA0/ AL/CPP Basic characteristics are: Among them, PE is suitable for low temperature, CPP is suitable for high temperature cooking, PA is to increase the physical strength and puncture resistance, AL aluminum foil is to increase the barrier performance, shading is generally used as an intermediate layer. PET increases mechanical strength, crisp. Then according to the demand, the combination of various properties, sometimes in order to increase the barrier (oxygen and humidity resistance) can use water resistant PVA high barrier coating. Can be customized according to different composite materials and thickness of the product. Storage environment temperature ≤38 ° C, humidity ≤90%. General product specifications: thickness 0.10mm and 0.14mm, three side sealing, sealing 10mm, product specifications and sizes can be customized according to customer needs.
Production process
Solid aluminum foil bag of whole production process: aluminum smelting, rolling, cold rolling, intermediate annealing cold-rolled - in the wool, roughing, aluminum foil rolling, finishing, cutting, aluminum foil product annealing, composite, bag making, three-dimensional aluminum foil bag product packaging -. In this aluminum foil bag process, from aluminum foil wool to the whole process of processing foil, and then in the compound bag.
advantage
Three-dimensional aluminum foil bag has good metal luster, good light resistance, good reflection ability to heat and light, metal luster and reflection ability is also very good to improve the brightness of three-dimensional aluminum foil bag printing color; Good isolation, strong protection, no gas and water vapor, to prevent moisture absorption, gasification, not easy to bacteria and insects damage; Shape stability is good, not affected by humidity changes. Easy to process, can be three-dimensional aluminum foil bag printing, color difference, embossing, surface coating, glue and paint; Composite aluminum foil bag, also has the advantages of isolation.
application
Suitable for use as carton packing lining bag, specifications can be customized according to customer requirements; Suitable for packing bags when loading export goods; Mainly used for dust-proof products, box lining, etc. Plastic dust cover for machine tools, boxes and other large parts; This product is suitable for material, textile products, clothing and other products of light and heavy packaging.
Note: Different raw materials can be selected according to the material requirements of customers, and the roots can be produced according to the appearance, length and thickness of customers' requirements. The packaging method can be based on customers' requirements, and the roots can be quoted according to the specifications and sizes. Three-dimensional aluminum foil bag is suitable for all kinds of circuit boards, electronic products, precision machinery parts, consumer goods, industrial products and other packaging. For example: used for all kinds of PC board, IC integrated circuit, optical drive, hard disk, electronic components, all kinds of LED industry SMT patch, light strip packaging, electronic equipment, precision hardware, auto parts and other packaging. The size can be customized according to the needs of customers, but also can be made into different sizes of flat/three-dimensional bags.
Suitable for soft drink packaging. Three-dimensional aluminum foil bag bag not only has the repeated packaging of PET bottle and the fashion of composite aluminum paper bag, but also has incomparable advantages in the printing performance of traditional beverage packaging. Because of the basic shape of the self-standing bag, the display area of suction nozzle bag is obviously larger than that of PET bottle, and it is better than the packaging of non-standing Bairi bag.
