An alloyed double-zero aluminum foil with high peel strength and high heat-sealing strength sp drug pack

Abstract

The embodiment of the present invention discloses an alloyed double-zero aluminum foil with high peel strength and high heat-sealing strength SP drug pack, which includes the following components calculated by mass percentage: Si 0.3-0.4%, Fe 0.8-1.2%, Cu≤0.02% , Mn≤0.50%, Ti 0.010—0.035%, Cr≤0.10%, Zn≤0.10%, Cd≤0.10%, Li≤0.10%, Na≤0.10%, Pb≤0.10%, Zr≤0.0003%, Mg≤0.05 %, V≤0.03%, B 0.002—0.02%, and the balance is Al. The double-zero aluminum foil provided by the invention contains Ti, Cr, Zr, V, B, Na and Pb, which improves the mechanical properties of the double-zero aluminum foil to a certain extent, and solves the problem that the mechanical properties of the aluminum foil in the prior art do not meet the requirements for use. The problem of peeling off is difficult during use. In the preparation method of the double-zero aluminum foil of the present application, by melting the main components and adding raw materials with less content in stages, the main components of the double-zero aluminum foil can be evenly distributed, and the mechanical properties of the double-zero aluminum foil can be improved.

Description

technical field [0001] The invention relates to the field of aluminum foil degreasing, in particular to an alloyed double-zero aluminum foil with high peel strength and high heat-sealing strength for SP medicine packs. Background technique [0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets by metallic aluminum. Its hot stamping effect is similar to that of pure silver foil hot stamping, so it is also called fake silver foil. Due to the soft texture, good ductility and silvery white luster of aluminum, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and darken in color, and will fade when rubbed or touched, so it is not suitable for hot stamping on the covers of books and periodicals that are stored for a long time. Aluminum foil can be divided into thick foil, single zero foil and double zero...
