Classification of aluminum foil

Aluminum foil has a variety of classifications, different aluminum foil also has a different role. The following simple classification of aluminum foil, according to the thickness of aluminum foil, shape, Aluminum Foil state or material can be classified.

Aluminum foil According to thickness difference can be divided into thick foil, single 0 foil and double 0 foil. ① thick foil: thickness of 0 1~0.2mm foil. ② Single 0 Foil: thickness of 0.0lmm and foil less than 0.1mm. ③ Double 0 Foil: The so-called double 0 foil is in its thickness of MM as the unit of measurement when the decimal point has two zero foil, usually the thickness of less than 0.0075mm. When expressed in English, Aluminum Foil the thick foil is called "heavy gauge foil '", a single 0 foil called "Medium gauge foil", and a double 0 foil called "light gauge". Foreign sometimes the thickness of ≤40ltm aluminum foil called light gauge foil, and the thickness of the aluminum foil >40BTM collectively known as heavy gauge foil.

Aluminum foil by shape can be divided into rolled aluminum foil and flaky foil. Aluminum foil deep processing of wool most of the roll-like supply, Aluminum Foil only a few handicraft packaging occasions only with flaky foil.

Aluminum foil According to the state can be divided into hard foil, semi-rigid foil and soft foil. ① hard foil: After rolling without softening treatment (annealing) of aluminum foil, without degreasing treatment, the surface of the residual shantou. Therefore, the hard foil in the printing, laminating, Aluminum Foil coating must be done before degreasing treatment, if used for forming processing can be directly used. ② semi-hard foil: aluminum foil hardness (or strength) between the hard foil and the soft foil, usually used for forming processing. ③ Soft foil: After the rolling after full annealing and softened aluminum foil, the material is soft, the surface is not residual oil. At present, most areas of application, such as packaging, laminating, electrical materials, Aluminum Foil are used in soft foil. Aluminum foil According to the surface state can be divided into one side light (single-sided light) aluminum foil and two-sided light (double-sided light) aluminum foil. ① one side of the light aluminum foil: Double rolled aluminum foil, after the volume of light, one side of the black, such aluminum foil is called a light aluminum foil. The thickness of a light foil usually does not exceed O. 025mm. ② Two-sided light aluminum foil: Single sheet rolling aluminum foil, both painting and roll contact, aluminum foil on both sides of the surface roughness of the rollers are divided into mirror two surface light aluminum foil and ordinary two-sided light aluminum foil. Two surface light aluminum foil thickness is generally not less than 0.01mm.

Aluminum foil According to the state can be divided into the element foil, embossed foil, composite foil, coated foil, color aluminum foil and printed aluminum foil. ① foil: After rolling, no other processing of aluminum foil, also known as light foil. ② Embossed Foil: The surface is embossed with various patterns of aluminum foil. ③ Composite Foil: The aluminum foil and paper, plastic film, cardboard laminating in-formed composite aluminum foil. ④ coated Foil: The surface is coated with various types of resin or lacquer foil. ⑤ Colored aluminum Foil: the surface is coated with a single color of aluminum foil. ⑥ Printing aluminum Foil: by printing on the surface to form a variety of patterns, patterns, text or picture of the aluminum foil, can be a color, up to 12 kinds of color.

Aluminum foil with light weight, Aluminum Foil airtight and cladding of good and so on-series of advantages, therefore, in many sectors of the national economy and People's daily life to obtain a wide range of applications, but at present it is mainly used in packaging, electromechanical and construction of the three major areas.

After aluminum foil processing is an important link of an enterprise, it is related to the yield and profit point of a company. The higher the yield, the greater the enterprise profit point. Of course, the yield is every a links to control, standardized operation, but also the need for sophisticated equipment and strong sense of responsibility of the leadership, staff. Equipment and operating specifications I do not understand, dare not to judge, I can only cut on the knife on the basis of practice analysis. Below I talk about why the split-cut, multilateral, powder. The problem of material itself and equipment is mostly related to blade stripping, multilateral and powder removing. There are usually two kinds of blades for aluminum foil slitting. One is a round blade, one is a slice of the blade also known as a razor. The razor blade is fixed to a point, the material rewinding passively cut, delimits. Aluminum foil is active slitting, the faster the speed, the smaller the blade resistance. The slower the opposite. The thickness of the blade corresponds to the resistance. The thicker the blade, the greater the resistance. The thinner the opposite. Because the razor blade is cut fixed, the knife edge and foil, thin material contact, tangent point prone to fatigue and fever, so after a period of time will not be sharp, knife blunt will appear tearing phenomenon, the emergence of powder burrs unavoidable. Of course, Aluminum Foil these are also related to slitting angles. Choosing Good razor blades is the first choice for solving these problems, and ceramic blades should be preferred.
