̥ aluminum foil classification
(1) according to the thickness according to the thickness difference can be divided into aluminum foil thick foil, single zero foil and double zero foil. (1) thick foil: thickness of 0.1 ~ 0.2 mm of foil. (2) the single zero foil: thickness of 0.01 mm and 0.1 mm/less than the foil. (3) dual zero foil: the so-called double zero foil is in its thickness to mm for the measurement unit after the decimal point two zero foil, usually less than 0.0075 mm thickness for the aluminum foil. Use English expressions, thick foil called "heavy gaugefoil ', 'single zero foil called" medium gaugefoil ", double zero foil says "lightgaugefoil' '. Sometimes foreign than 40 LTM thickness of aluminum foil called light gauge foil, and the thickness > 40 BTM of aluminum foil collectively referred to as heavy gaugefoil.
(2) according to shape aluminum foil according to shape can be divided into roll shape aluminum foil and flake aluminium foil. Aluminum foil deep processing wool is roll shape most supply, only a few handicraft industry packing occasions sheets with aluminum foil.
(3) according to state by state aluminum foil can be divided into hard foil, half hard foil and soft foil. (1) hard foil: after rolling without softening (annealing) of aluminum foil, not through degrease processing, surface by the more difficult. So hard foil in printing, joint, coating must be skimmed treatment before, if used for machining and forming can be used directly. (2) half hard foil: aluminum foil hardness (or intensity) in hard foil and soft foil between the aluminum foil, normally used for forming. (3) soft foil: after rolling through full annealing and softening the aluminum foil, and the material of the soft, surface no residual oil. Most current applications, such as packing, composite, electrical materials, use soft foil.
(4) according to the surface foil surface state can be divided according to a light aluminum foil and LiangMianGuang aluminum foil. (1) a light aluminum foil: ShuangGe rolling of aluminum foil, liu side after light,-hair black face, such aluminum foil called a light aluminum foil. A light aluminum foil, the thickness of the usually no more o. 025 mm. (2) LiangMianGuang aluminum foil: leaflet rolling in the aluminum foil, two paintings and roll contact, the two sides of the aluminum foil for roller surface roughness and divided into two different mirror surface light aluminum foil and ordinary 2 face light aluminum foil. 2 face light aluminum foil, the thickness of the general not less than 0.01 mm.
(5) with aluminum foil and according to state by state can be divided into element foils, embossing foil, composite foil, coating foil, coloring of aluminum foil and printing the aluminum foil. (1) element foils: after rolling without any other processing of about aluminum foil, also called the light foil. (2) the embossed foil: on the surface, there are all kinds of pressure of aluminum foil decorative pattern. (3) composite foil: the aluminum foil and paper, plastic film, paper joint is in the form of composite-aluminum foil. (4) coating foil: surface with all kinds of resin or paint of aluminum foil. (5) colored aluminum foil: with a single color on the surface of aluminum foil. 6 printing aluminum foil: through the printing on the surface the formation of decorative pattern, design, text or picture of aluminum foil, can be a kind of color, the most to 12 kinds of color. Soft aluminum foil could further down into the quad-zero foil, used for upscale decoration.
(6) according to the purposes in accordance with the different USES foil can be roughly divided into medicine foil, food foil, containers foil, air conditioning foil, packing foil, electronic foil, cable foil, sealing foil, tape foil, barbecue foil, close water foil
