Development of Vacuum metallized pet film

Aluminum foil and Vacuum metallized film

The attraction of the vacuum metallized film is started by aluminum foil. The aluminum foil  is used on the flexible plastic packaging is usually between the 6-20μm thickness.

Aluminum foil with silvery luster, directly on the aluminum foil printing transparent ink, can have a unique gold luster aluminum foil has a good shading, gas resistance, moisture resistance, a good thermal conductivity, electromagnetic shielding. One of the most sudden is the barrier properties of aluminum foil, in the aluminum foil thickness sufficient premise, can completely obstruct the gas and moisture, so in the soft plastic packaging substrate film, aluminum foil is an indispensable material, is widely used in pharmaceutical packaging, food packaging, especially the need for high-temperature cooking and preservation of relatively long time of drugs,

Cosmetics and other high-grade products in the flexible packaging. But aluminum foil has a fatal flaw-bending, aluminum foil is easily to get cracks, affecting the barrier of aluminum foil, while the price of aluminum foil more expensive. In the 80 ‘s, a new technology of one by one vacuum metallized film was introduced.

Since then, more and more people began to change without affecting the quality requirements of the premise, instead of aluminum foil to use the vacuum metallized film, thereby reducing packaging costs. The so-called vacuum aluminum refers to the high vacuum, the aluminum once liquefied immediately after vaporization, and then cooling on the plastic film surface, forming a layer with a good metal gloss thickness of about 300~600-aluminum coating. The thickness of aluminized layer is also expressed by means of light transmittance, optical density or square resistance. According to the coating online understanding, Vacuum aluminized film is generally temperature-resistant and mechanical processing performance of Bopp, BOPET, Bopa, CPP and other materials. In this way, the vacuum aluminized film has both mechanical and physical properties similar to that of the substrate, as well as a barrier property similar to aluminum foil.

We produce high quality metallized PET Film,which also called VMPET film, Vacuum metallized pet film.Aluminum metallized pet film.

our metallized pet film are widely used for printing,lamination,food packaging, decorative purposes, and also for specialty applications including insulation and electronics.

metallized pet film normally refer to Aluminum metallized pet film,which are made entirely of light metal, metallized PET foils are plastic foils which are only evaporated with aluminium powder in a high vacuum. For this process, it is used pure aluminium in powder form with an aluminium content of at least 99,98%. The films produced this way obtain a metallic shine and thereby achieve a special optical effect.

In addition to the optical effect, the aluminum vaporization serves in particular to improve its barrier effects against vapours, gases and aromas in comparison to non-metallized plastic film. Overall, the metallized PET films are less gas-tight than “real” aluminum foil, but more tear resistant, more flexible and lighter. Also, they are less sensitive to corrosion and not as winkle-prone as pure aluminium foil.
