Aluminium foil laminating machine manufacturers talk about the market development of aluminum foil
According to the introduction of aluminum foil laminating machine manufacturers, with the improvement of people’s living standards and the development of tourism, the demand for beverages and canned foods such as beer and soft drinks has increased. These need modern packaging and decoration to facilitate the international market. competition.
In recent years, in order to meet the market requirements, people have developed good shielding plastic films and spray foil packaging materials, but their overall performance is not as good as over-coating and laminating can be compensated and improved.
Therefore, it can be said that aluminum foil has a variety of excellent properties, relatively perfect packaging materials, in many areas have fully demonstrated its broad application prospects.
In order to improve the rolling efficiency and the quality of aluminum foil products, modern aluminum foil rolling mills develop in four directions: large roll, wide width, high speed, and automation. The width of the roller body of modern aluminum foil rolling mills has reached more than 2200mm, the rolling speed has reached 2000m/min or more, and the roll weight has reached more than 20t.
The corresponding rolling mill automation level has also been greatly improved. The thickness control system (AGC) is generally installed and most of the AFCs are installed. The aluminum foil industry is facing a period of rapid development.
Aluminum foil can be divided into rolled aluminum foil and sheet aluminum foil by shape. Most of aluminum foil deep processing wool is supplied in roll form, and only a few hand-industry packaging uses foil aluminum foil.
Aluminum foil laminator manufacturers said that according to the state of aluminum foil can be divided into hard foil, semi-hard foil and soft foil.
1 Hard Foil: Aluminum foil that has not been softened (annealed) after rolling is free from defects on the surface when it is not degreasing. Therefore, the hard foil must be degreasing before printing, laminating, and coating, and can be used directly if it is used for forming processing.
2 Semi-hard foil: Aluminum foil Hardness (or strength) Aluminum foil between hard foil and soft foil, usually used for forming.
3 Analysis of aluminum foil laminating machine manufacturers, soft foil: aluminum foil that has been fully annealed and softened after rolling. The material is soft and there is no residual oil on the surface. At present, most applications, such as packaging, composites, and electrical materials, use soft foils.
