After the aluminum foil is combined with plastic and paper, the shielding properties of aluminum foil are combined with the strength of paper and the heat sealability of plastic, which further improves the shielding performance against water vapor, air, ultraviolet rays and bacteria necessary as packaging materials, greatly Broadened the application market of aluminum foil. Because the packaged items are fully isolated from external light, humidity, and air, the packaging is fully protected.
1100 aluminum foil is industrial pure aluminum with high corrosion resistance, electrical and thermal conductivity. The 1100 aluminum plate has low density and good plasticity. It can produce various aluminum materials through pressure processing, but its strength is low. 1100 pure aluminum plate is usually used in places that require good processability, high corrosion resistance, and do not need too high strength, such as nameplates, sheet metal products, hollow hardware, etc. The surface should not have rolling defects such as variegated spots, herringbone patterns, bright lines, and surface color differences that affect the use. The level of oil on the surface of the aluminum foil in the H18 state should reach 31 dyne; there should be no oil spots and no serious gasoline smell.
