Aluminum foil for packaging can be regard as the most common seen application area of aluminium foil products. The packaged items range from food, medicine, cable, cigarette and so on. Due to its excellent characteristics, aluminum foil is widely used in packaging materials for food, beverages, cigarettes, medicines, photographic plates, household daily necessities, etc. Electrolytic capacitor materials, thermal insulation materials for buildings, vehicles, ships, houses, etc can also use aluminium foil as raw materials, thus we can see that aluminum foil is an integral part of life.
The thickness of aluminum foil for packaging is really thin, and double zero aluminum foil is more often applied. The double-zero aluminum foil is relatively thin, Mainly used in the packaging industry, such as food packaging, cigarette packaging and so on. It is widely used in food packaging, refrigeration and storage; catering, hotels, households, etc. It has the advantages of preservation, quality preservation and environmental protection. Aluminum foil packaging is the latest environmentally friendly package product in the world. Aluminum foil containers mainly include: barbecue trays, aviation lunch boxes, fast food boxes, food turnover trays, cake cups, stove mats, etc. The specifications can be customized according to customer requirements.
To improve the quality of aluminum foil for packaging, the slitting process is important. Double zero aluminum foil slitting process control: The surface oil removal quality of aluminum foil is not only related to the quality control of the rolling process and annealing process, but also related to the tightness of the slitting process. Since the aluminum foil coil is surrounded by hot air in the annealing furnace, the rolling oil between the foil layers needs to escape through a certain gap and volatilize into gas. If the aluminum foil coil is too tight, the rolling oil will evaporate. becomes difficult. In production, it is very important to control the void ratio of the double zero aluminum foil. In the slitting operation, according to different material widths, the taper tension of slitting is adjusted between 6% and 32%, and a good oil removal effect is achieved.
