What is VMPET Film?

Jun 10,2022
VMPET film is short for vacuum metalized polyester film, that is, under vacuum conditions, a thin layer of aluminum atoms are deposited on the surface of the PET (polyester) film substrate to finally achieve a bright metal film, which is widely used in flexible packaging and self-supporting. Bag packaging.

Main attribute

High barrier properties

The reason VMPET film is so widely used in stand-up pouch packaging is its high barrier properties and much lower cost than aluminum foil.

Bright metal effect

For stand-up pouch packaging, the bright metallic effect means that the final packaging can achieve a more vivid and solid effect. Just like the ink is printed on a clear PET film, in fact, even with an additional PE layer, the actual artwork is halfway visible.

Sunshine shield properties

Sun-shielding properties mean that packaging using VMPET film can well protect internal products from sunlight, such as potato chips, liquid detergents, biscuits, instant noodles, and more. VMPET film is the best solution for the packaging of these products.

These three excellent properties make VMPET film widely used in flexible packaging and stand-up pouch packaging.

So, how is VMPET film produced?

The vacuum metallization of aluminum wire can only be carried out under vacuum conditions. If there is air inside the metalizing machine, oxygen will cause the aluminum wire to burn easily, and may also cause an explosion, because, during the production process, the temperature must be heated to nearly 2000 degrees Celsius, so that the aluminum wire evaporates into aluminum gas, which makes the aluminum gas evenly deposited on the surface of the PET film.

The thickness of the aluminum layer is very thin, only 350-450 Å (1 Å = 10^(-10) m), while the PET film is 12 microns (1 micron = 10^(-6) m)

Which to choose Aluminum foil coated PE or Metalized pet film coated PE ?

It depends on what product to be made in final procedure. Aluminum foil coated pe is with at least 97% reflectivity, it can be bonded to EPE foam but also most of time for laminated with bubble. Metalized pet film coated PE with lower reflectivity ,but it is with strong surface.

I am a insulated liner/bag manufacturer,what product do you suggest?

There maybe bubble lamination machines and heating pressure lamination machines in your factory, we suggest Aluminum foil 7mic+PE20mic, and Metalized PET film12mic+PE15mic.

If i would like to get a quote ,what information shall i need to know first?

You are request to telling application, material structure,thickness and roll width and quantity.

What is the MOQ and how is packaging?

MOQ is 1000kgs for each product, packaging depends on roll size, common width is 1200mm and 1500mm, length are 4000m to 5000m per roll. Rolls can be vertically packed on pallet also accept to do horizontal suspending packaging.

Is this product by wet lamination or by dry lamination?

Both wet lamination line(extrusion coating) and dry lamination line(glue coating) are equiped in our Pengyuan group.
