Aluminum Foil Has Good Plasticity
Jun 22, 2017


A metal foil directly into a sheet of hot stamping material, the hot stamping effect and the effect of pure silver foil stamping similar, it is also known as false silver foil. As the texture of aluminum is soft, good ductility, with silver and white luster, if the calendering after the film, with sodium silicate and other substances mounted on the offset paper made of aluminum foil, but also for printing. Aluminum Foil But the foil itself is easy to oxidize and darken the color, friction, touch and so will fade, it is not suitable for long-term preservation of the book cover and other hot stamping.

2 Classification of aluminum foil:

By thickness

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

① thick foil: the thickness of 0.1 ~ 0.2mm foil.

② single piece of foil: the thickness of 0.01mm and less than 0.1mm / foil.

③ double zero foil: the so-called double-zero foil is in its thickness in mm units of measurement when the decimal point after the two zero foil, usually less than 0.01 thickness of aluminum foil, 0.005 ~ 0.009mm aluminum foil.

By shape

Aluminum foil can be divided into roll-like aluminum foil and sheet aluminum foil. Most of the deep processing of aluminum foil is rolled, and only a handful of handicrafts are used for sheet aluminum foil.

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

① hard foil: after rolling without softening (annealing) of the aluminum foil, without degreasing treatment, the surface of the cloth is poor. So hard foil in the printing, bonding, Aluminum Foil coating must be defatted before treatment, if used for forming can be used directly.

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

③ soft foil: after rolling through the full annealing and soften the aluminum foil, soft material, the surface without residual oil. At present most of the application areas, Aluminum Foil such as packaging, composite, electrical materials, etc., are using soft foil.

By surface state

Aluminum foil according to the surface state can be divided into one side of the aluminum foil and aluminum foil on both sides.

① single-sided aluminum foil: double-rolled aluminum foil, after the volume side of the light, - hair Ukraine, this aluminum foil called a side of the aluminum foil. The thickness of an aluminum foil is usually not more than o. 025mm.

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

3 aluminum foil features:

Aluminum foil with a clean, hygienic and shiny appearance, it can be made with many other packaging materials, integrated packaging materials, and aluminum foil surface printing effect is better than other materials, in addition to the following characteristics of aluminum foil:

(1) aluminum foil surface is extremely clean, hygienic, any bacteria or microorganisms can not grow on its surface.

(2) aluminum foil is a non-toxic packaging material, Aluminum Foil it can be in direct contact with food and no harm to human health.

(3) aluminum foil is a tasteless and odorless packaging material, will not be packaged food has any smell.

(4) If the foil itself is not volatile, it itself and the packaged food will never dry or shrink.

(5) whether at high temperatures or at low temperatures, aluminum foil will not have the phenomenon of oil penetration.

(6) aluminum foil is an opaque packaging material, so for sunshine irradiation products, such as margarine is a good packaging material.

(7) aluminum foil has a good plasticity, it can be used for packaging various shapes of products. Can also be caused by any shape containers.

(8) aluminum foil hardness, tension strength is also large, but its tear strength is small, so easy to tear.

(9) aluminum foil itself can not be heated and sealed, must be applied in the surface of heat-resistant materials, such as pe to heat closed.

(10) When the aluminum foil is in contact with other heavy metals or heavy metals, Aluminum Foil there may be adverse reactions
