thickness

Aluminum foil thickness can be divided into thick foil, single-zero foil and double zero foil.

① thick foil ("heavy gaugefoil"): the thickness of 0.1 ~ 0.2mm foil.

② "single gauge foil" ("medium gauge foil"): thickness of 0.01mm and less than 0.1mm / foil.

③ double-foil ("light gauge foil"): the so-called double zero foil is in its thickness in mm as the unit of measurement after the decimal point has two zero foil, usually less than 0.01 thickness of the aluminum foil, that is 0.005 ~ 0.009mm aluminum foil . Abroad, sometimes the thickness of the foil ≤ 40ltm called "light gauge foil", and the thickness of> 40btm aluminum foil collectively referred to as "heavy gauge foil".

Shape

According to the shape of aluminum foil can be divided into rolled aluminum foil and aluminum foil. Most of the deep processing of aluminum foil roll was the supply of only a handful of handicraft packaging occasions with sheet aluminum foil.

Aluminum foil can be divided into hard foil, semi-hard foil and soft foil according to the state.

① hard foil: rolling without softening treatment (annealing) of the aluminum foil, without degreasing treatment, the surface Bu Bu Shan. Therefore, rigid foil in the printing, lamination, coating must be degreased before processing, if used for forming processing can be used directly.

② semi-hard foil: aluminum foil hardness (or strength) in the hard foil and foil between the foil, usually used for forming process.

③ soft foil: after rolling fully annealed and soft aluminum foil, soft material, no residue on the surface. Most applications, such as packaging, composites, electrical materials, etc., use soft foil.

Surface state

Aluminum foil according to the surface state can be divided into one side light aluminum foil and two-sided aluminum foil.

① single-sided aluminum foil: double-rolled aluminum foil, sub-volume after a bright side, - surface hair Ukraine, such as aluminum foil known as a side. The thickness of one side of the aluminum foil is usually not more than 0.025 mm.

② double-sided aluminum foil: single-rolled aluminum foil, roll contact on both sides, aluminum foil on both sides due to different surface roughness of the roll is divided into mirror two-sided aluminum foil and ordinary two-sided aluminum foil. The thickness of two-sided aluminum foil is generally not less than 0.01mm.

Processing status

Aluminum foil can be divided according to the processing state of foil, embossed foil, composite foil, coated foil, aluminum foil and printed aluminum foil.

① foil: rolling without any other processing of aluminum foil, also known as light foil.

② embossed foil: the surface pressure of a variety of patterns of aluminum foil.

③ composite foil: the aluminum foil and paper, plastic film, cardboard fit in - from the formation of composite aluminum foil.

④ coated foil: the surface coated with various types of resin or paint aluminum foil.

⑤ colored aluminum foil: the surface coated with a single color of aluminum foil. ⑥ Printing Aluminum Foil: It can form a variety of patterns, patterns, text or picture aluminum foil by printing on the surface, can be a color, up to 12 colors.

Soft aluminum foil can also be further suppressed into four foil, for high-end decoration.
