What is aluminized film and aluminum foil？
Aluminized film is to evaporate high-purity aluminum wire into gaseous state at high temperature (1100~1200 ℃) through vacuum aluminizing process, and then when the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules are deposited on the surface of the plastic film to form a bright light. Metallic colored film.
Aluminized film is a kind of composite flexible packaging material formed by coating a very thin layer of metal aluminum on the surface of plastic film by a special process. Because it has the characteristics of both plastic film and metal, it is a packaging material with beautiful appearance, excellent performance and strong practicability.
Aluminum foil is a material that is directly rolled from metal aluminum into thin sheets. It has soft texture, good ductility, silver-white luster, moisture-proof, air-tight, light-shielding, wear-resistant, non-toxic and tasteless. It is widely used in food, Beverages, cigarettes, medicines, photographic plates, household daily necessities, construction, vehicles and other industries.
Features of aluminized film
1. Save energy and materials and reduce costs.
2. It has excellent folding resistance and good toughness, with few pinholes and cracks, and no bending and cracking, so the barrier property to gas, water vapor, odor, light, etc. is improved.
3. It has excellent metallic luster, and the light reflectivity can reach 97%; and it can form a color film through coating treatment, and its decorative effect is inferior to that of aluminum foil.
4. Partial aluminum plating can be performed by shielding type to obtain any pattern or transparent window, and the contents can be seen.
5. The aluminized layer has good electrical conductivity and can eliminate electrostatic effects; its sealing performance is good, especially when packaging powder products, it will not pollute the sealing part, ensuring the sealing performance of the packaging.
6. It has good adaptability to post-processing such as printing and compounding.
How to distinguish between aluminized film and aluminum foil?
Difference 1: appearance
Aluminum foil: In terms of color, the package is silvery white or silvery gray; the reflectivity is not as good as that of aluminized film.
Aluminized film: the package is silver yellow or silver black; high brightness.
Difference 2: feel
Aluminum foil: feel thick and crisp, heavy.
Aluminized film: feel lighter and softer than aluminum foil packaging.
Difference 3: folding
Aluminum foil: The package is prone to dead folds and dead marks when the package is folded.
Aluminized film: While aluminized packaging does not, it will snap back quickly.
Difference 4: burn
Aluminum foil: The package is ignited with fire, it is not easy to burn, and the aluminum layer will roll back. The aluminum foil package will leave gray slag after burning.
Aluminized film: When the film is burned, different plastic films will burn, and there is no residue of aluminum slag.
