Metallized paper is finalized by depositing the surface of paper substrate material with a thin layer of evaporized aluminums, enabling it with a metallic barrier performance, decorative and protective properties to the paper substrate. It can be further processed into labels, bags, wraps, sleeves and pouches, which can be widely accepted for the packages of various products.
Here, in this post, we are going to guide our customers with a better understanding on metallized paper, and try to assist the customers to achieve the expected sustainable packages for their lovely products.
More than metallization on kraft paper, the surface of metallized paper is actually reinforced and optimized for better processing, like printing, laminating. A layer of clay coating is applied onto the porous surface, which is intended to achieve a more smoothe and better printability. The primer coating on top of aluminum metallized layer will not only work as protection of the aluminum, but also enhance the adaptability of the inks to be printed.
Nevertheless, the metallized paper we choose comes to the top choice when the customers expect to get the most of compostable paper packages.
Metallized paper is playing a more and more important role in compostable packages. As paper is considered the biodegradable materials which can degrade under so many nature conditions, so the compostable packages acheived with metallized paper are much flavored in the consumer market.
Other than directly evaporizing the aluminum atoms onto the film surface, the aluminumized layer will have to be transfered to the paper substrate with an intermediate operation. First, the aluminum will have to be deposited onto the surface of a release film, which can transfer the aluminumized layer to the surface of treated paper under a certain pressure and thermal conditions. After that, the coating of printing primer will be coated on top of the aluminum layer
The metallized paper we use will be able to meet the requirements for BRC food certifificate.
We hereby commit our metallized paper will be in compliance with FDA regulations, and thir-party inspection is available on customer’s request.
Complicated artwork design can be printed onto the surface of metallized paper with the highest standard of color consistency.
Water-based inks are available for the flexo printing onto metallized paper, which is able to present a better sustainability for the final packages.
When the artwork is not complicated, gravure printing can be applied to achived the printing.
Digital printing can be applied when the customer just start up their business and would like to a lower-cost for the startup.
Metallized paper, can be further laminated with other biodegradable film materials, such as home compostable cellulose paper, biodegradable PLA+PBAT film, industrial compostable BOPLA membrane, biodegradable PBS film, to achieve the compostable standup pouches. The multi-functions of the compostable foil laminate can meet the different requirements of the various products. You may learn more here about the compostable laminated foil based on metallized paper substrate.
The degradation of metallized paper in nature soil conditions is quite like kraft paper. The aluminumized layer will react with water and oxygen into AlOx, which naturally exist on earth in very short time. so actually metallized paper can be taken as fully home compostable material.
We are here to perform our own test to observe the degradation progress of metallized paper in our garden soil conditions, and you may learn more with below link.
Metallized paper is extending its applications for more and more products, and here we are glad to share with you our experience. Just reach us if you need further assistance.
As environmental concerns grow, more and more companies are looking for eco-friendly and sustainable alternatives to traditional plastics. Protecting the environment requires far-reaching projects, that’s why Tongli is always looking for new ways to improve. Lucky for us, we now live in a world where it becomes easier to source sustainable materials, and now we are moving steadily to a more sustainable future.
