Definition of food aluminum foil packaging bag
Aluminum foil composite film is the most commonly used composite roll film, which usually contains pure aluminum (AL) and aluminum plating (VMPET).
Aluminum foil composite film material
Aluminum foil (AL)
Aluminum foil is a thin sheet formed by rolling high purity aluminum for many times. It is an excellent heat conducting and shading body,
The purity of aluminum foil for packaging is above 99.5%.
aluminizer
Vacuum aluminizing film is a kind of thin film which accumulates aluminum vapor precipitation on various substrates under high vacuum condition
The thickness is generally 350 to 400A.
Characteristics of aluminum foil composite film
Features of aluminum foil
Good mechanical strength, light weight, no thermal adhesiveness, metallic luster, good shading, strong light reflection ability, no thermal adhesion
It is easy to be corroded, good barrier, moisture and water proof, strong air tightness and fragrance retention.
Characteristics of aluminum coating
It has metallic luster, high gas barrier and low adhesion viscosity, so it is easy to transfer aluminum coating after composite processing.
Composite application of aluminum foil
Aluminum foil application
Pharmaceutical packaging materials, high temperature cooking food packaging, barrier packaging (flavor, spice) and electromagnetic shielding packaging.
Application of aluminum coating
Light, non cooking barrier packaging, such as seaweed packaging bags, puffed food bags, biscuit food packaging bags.
