Talking About The Classification Of Aluminium Foil Jumbo Roll

Talking about the classification of aluminium foil jumbo roll

thickness

Aluminium foil jumbo roll can be divided into thick foil, single zero foil and double zero foil according to the thickness difference.

① Thick foil ("heavy gaugefoil"): foil with a thickness of 0.1 to 0.2 mm.

②Single zero foil ("medium gauge foil"): foil with a thickness of 0.01mm and less than 0.1mm/.

③Double zero foil ("light gauge foil"): The so-called double zero foil is a foil with two zeros after the decimal point when its thickness is measured in mm, usually aluminium foil jumbo roll with a thickness of less than 0.01, that is, aluminium foil jumbo roll with a thickness of 0.005~0.009mm . In foreign countries, aluminium foil jumbo roll with a thickness of ≤40ltm is sometimes referred to as "light gauge foil", and aluminium foil jumbo roll with a thickness of >40btm is collectively referred to as "heavy gauge foil".

shape

Aluminium foil jumbo roll can be divided into roll aluminium foil jumbo roll and sheet aluminium foil jumbo roll according to the shape. Most of the aluminium foil jumbo roll deep-processing wool is supplied in rolls, and sheet aluminium foil jumbo roll is only used in a few handicraft packaging occasions.

According to the state, aluminium foil jumbo roll can be divided into rigid foil, semi-hard foil and soft foil.

①Hard foil: The aluminium foil jumbo roll that has not been softened (annealed) after rolling, and has no residue on the surface when it is not degreasing. Therefore, the hard foil must be degreased before printing, lamination, and coating, and it can be used directly if it is used for forming.

②Semi-hard foil: aluminium foil jumbo roll whose hardness (or strength) is between hard foil and soft foil, usually used for forming.

③Soft foil: aluminium foil jumbo roll that has been fully annealed and softened after rolling. The material is soft and there is no residual oil on the surface. Most applications, such as packaging, lamination, electrical materials, etc., use flexible foils.

surface condition

Aluminium foil jumbo roll can be divided into one-sided smooth aluminium foil jumbo roll and two-sided smooth aluminium foil jumbo roll according to the surface state.

①Single-sided smooth aluminium foil jumbo roll: double-rolled aluminium foil jumbo roll, one side is bright after sub-rolling, and the other side is black, such aluminium foil jumbo roll is called one-sided smooth aluminium foil jumbo roll. The thickness of one side light aluminium foil jumbo roll is usually not more than 0.025mm.

②Double-sided smooth aluminium foil jumbo roll: single rolled aluminium foil jumbo roll, both sides are in contact with the roll, and the two sides of the aluminium foil jumbo roll are divided into mirror two-sided smooth aluminium foil jumbo roll and ordinary two-sided smooth aluminium foil jumbo roll due to the different surface roughness of the roll. The thickness of the two-sided glossy aluminium foil jumbo roll is generally not less than 0.01mm.
