A Brief Introduction Based On The Thickness And Shape Of The Aluminium Foil Jumbo Roll Thickness

A brief introduction based on the thickness and shape of the aluminium foil jumbo roll

thickness

According to the different thickness, aluminium foil jumbo roll can be divided into thick foil, single zero foil and double zero foil.

① Thick foil: 0.1~0.2mm thick foil.

②Single-chip microcomputer: the thickness is 0.01mm, and less than 0.1mm/piece.

③Double zero foil: The so-called double zero foil refers to the foil with two zeros after the decimal point of thickness, in millimeters. The thickness of aluminium foil jumbo roll is generally less than 0.01 mm, that is, the thickness is between 0.005 and 0.009 mm. This thick foil is called "heav" in English.

Single zero foil is called "medium gauge foil", double zero foil is called "medium gauge foil", and double zero foil is called "optical gauge foil". aluminium foil jumbo roll with a thickness of ≤ 40 mm is sometimes referred to as lightweight foil abroad, and foil with a thickness of more than 40 btm is collectively referred to as thick gauge foil.

shape

According to the shape of the foil, aluminium foil jumbo roll can be divided into roll and sheet. Most of the wool for deep processing of aluminium foil jumbo roll is supplied in coils, and sheet aluminium foil jumbo roll is only used in a few process packaging occasions.

aluminium foil jumbo roll can be divided into hard foil, semi-hard foil and soft foil.

①Hard foil: The aluminium foil jumbo roll that has not been softened after rolling will remain on the surface without degreasing treatment. Therefore, the hard foil must be degreased before printing, laminating and coating. If it is used for molding, it can be used directly.

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

③After the soft foil is rolled, complete annealing to soften the aluminium foil jumbo roll. The material is soft and there is no residual oil on the surface. Most application areas, such as packaging, composite materials, electronic materials, etc., use soft foils.

surface condition

aluminium foil jumbo roll can be divided into single-sided smooth aluminium foil jumbo roll and double-sided smooth aluminium foil jumbo roll according to surface conditions.
