Aluminum Foil For flexible packaging/Laminated
Aluminum foil is a popular packaging material at present.
Properties: non-toxic, excellent heat conduction and shading;Moisture - proof, air - tight, fresh
In the field of modern printing, aluminum foil products as printing materials mainly include:
Aluminum foil, aluminum foil composite materials, aluminum plating materials, etc.
The most common aluminum foil composite material is aluminum foil paper.Today, small hui for you to introduce the aluminum foil printing process.
Aluminum foil paper is a kind of high-grade packaging paper, it can replace the large area of anodized hot stamping, the product color is gorgeous, not only improve the grade of the product, but also improve the added value of the product, widely used in high-end commodity trademarks and packaging.
Aluminized paper in some developed countries has been a kind of environmental protection of new material, widely used in product packaging, also become a development trend in China.
The structure of aluminum foil
Composite aluminum foil paper is mainly composed of paper base (aluminum foil lining paper), aluminum foil, coating layer and so on.
Aluminum foil backing paper: it is a kind of processing paper with high requirements. The quantitative range is 21~50 g/m2.
Aluminium foil: Rolled from the metal aluminium.
Properties of aluminum foil
First: with a smooth surface, not conducive to ink transfer and absorption.
The aluminum foil layer structure is tight, the surface is almost void, does not have the absorption and permeability of paper.Therefore, after printing ink layer of binders, solvents and water can not be absorbed and stay on the surface of the aluminum foil, affecting the initial drying rate of the ink layer, resulting in imprinting stains.
Second: aluminum foil due to the surface of the aluminum foil layer and the paper between the density, strength and stability and other physical properties of the big difference, the two different properties of the material composite, the expansion rate is not consistent, easy to be affected by environmental temperature and humidity curly.
When the moisture content in the ambient air is greater than that in the lining paper, the lining paper becomes hygroscopic and elongates, and the foil paper curls to the foil surface.
When the water content in the ambient air is less than the water content in the lining paper, the lining paper dehydrates and shrinks, and the foil paper curls to the lining paper surface.
