5 Areas Where Metallized Films Are Superior to Foils

5 Areas Where Metallized Films Are Superior to Foils

Issue Time:2022/06/15
Looking for ways to increase the barrier properties of your packaging? Here are some factors to consider when optimizing packaging barriers and increasing production efficiency. 

High-barrier metallized PET films have barrier values ranging from 0.31–0.46 g/m 2 /day water vapour barrier and 0.31–0.46 cc/m 2 /day oxygen barrier, and they outperform foils both in production and in the final product advantage packaging integrity.

1. There is no doubt that metallized PET film has better puncture resistance than foil. From the moment a product is manufactured, packaged and shipped, the package will be bent countless times, and pinholes and flex cracks will appear. While the product remains intact, the foil barrier may be adversely affected by vibrations from the contents, creating tiny perforations. High-barrier metallized PET films can improve the shelf life of metal foils by resisting these perforations and maintaining their high-barrier properties.

2. Foil has dead-fold properties that perpetuate creases and wrinkles. Reaching store shelves through a variety of channels, a package may look stale by the time it reaches consumers. Without the memory properties of foil, metallized PET film will withstand this treatment, arriving on store shelves with a fresh and original look and full graphics.

3. Compared with foil, metallized PET film can run at a faster line speed. Typically operating at thinner gauges than standard gauge packaging-grade foils, metallized PET films can be sealed at lower temperatures, increasing line speeds.

4. Due to the different surface properties, the sealing performance of the metallized film is generally better than that of foil. Aluminium hydroxide is produced when the foil is exposed to moisture in the atmosphere and is therefore prone to inconsistent treatment levels across the web, resulting in poor adhesion in foil lamination. Converters found that once they switched to metallized PET films, the problem was corrected. The improved sealing performance also means less sealant is required to achieve a strong bond, which will save money.

5. Puncture resistance, memory properties, minimal investment and increased productivity; all of these factors mean stronger packaging and a more economical way to create your barrier solution.

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.
