Metallized paper, similar to metallized film, is achieved with a thin layer of aluminum atoms onto the surface of paper substrate (of course, with many variants of paper types), and finally a bright metallic paper is finalized, with property as below
- High barrier performance against common paper
- Bright metallic, that can create great metallic background for artwork printing
- Fragrance protection
- Better sunlight sheilding
Plain metallized paper is just with a thin layer of aluminum on surface, and also a varnish is applied on top to protect the aluminum layer. The graphic structure of metallized paper is as below.
Generally, there are two craftsmanship to apply the metallic aluminum coating onto the paper surface, one is called direct metallization coating, and the other is called transfer coating.
With the assistance of transfer coating , the surface of plain metallizied layer can be enabled with further effect, like gold, holographic, multi-lens effect, which can provide better decoration and package purpose in specific application. Below graphic shows the typical structure for holographic metallized paper.

Both sides of metallized paper can be printed, however with different effect and applications.
Print on metallized layer
Beer labels are the most common applications where artwork is printed on the aluminum metallized layer of the metallized paper, as it will be able to present metallic solid effect.
Print on paper side
With clay coating on the paper substrate, the surface is smoothe enough to present the artwork in a vivid way, and artwork can be directly printed on the outside side of paper, and then converted into kinds of standup pouch packages.

Metallized paper can be further laminated with other film materials to achieve multi-function purpose.
- Metallized Paper/LDPE
- Metalized Paper/BOPLA, working as lidding foil
- Metallized Paper/PLA, then be converted into kinds of pouches and lidding foil.
- Metallized Paper/Cellulose film
- Matte BOPP/Metallized Paper/LDPE, lowest cost of matte finish paper pouch foil
Printing, coating, and lamination are all available to be processed on to metallized paper foil, which can be further converted into kinds of pouch packages,lidding foils, labels etc
With paper substreat, Metallized paper should be compostable in nature conditions.
and we are performing the compost and biodegrade test of metallized paper 69 gsm which is buried in the soil of our garden, you may read more here.

The holographic rainbow effect can be widely applied for decoration purpose in our daily life.
With artwork print, Metallized paper can be laminated with other film material and then formed into standup pouch packages, for cookies, snacks, coffee beans etc.
