Based on the substrate material of cellulose paper, metallized cellulose film is going to achieve much better barrier performance when a thin layer of aluminum astoms are deposited onto the surface. It can be a reinforced layer for products that needs to be kept away from moisture, oxygen, grease etc.
Here, in this post, we are going to guide you with a better understanding on this film, and try to assist the customers to achieve the ideal compostable packages for their lovely products.
The barrier performance of a compostable package matters much when it is intended for products that is senstitive to outside factors, like moisture, sunlight, oxygen, or greases. Cellulose film is of good barrier to oxygen, however sensitive to water. Water can open its molecular structure and pass through the film easily. Vacuum metallization can improve the barrier performance, however it is not so firmable when the film faces environment with high humidity. There are ways to improve the resistance against moisture.
Our company is now outputing gorgerous compostable pouches and rolls for various products based on metallized cellulose paper. When metallized cellulose film is trapped between the foil materials, Not only the print effect is largely imporved win vivid effect, but also the protective function is reinforced as final packages.
The craftsmanship of vacuum metallization can be applied on to cellulose film substrate, and achieve a bright metallic appearance and improved barrier performance. Aluminum wire with purity higher than 99.99% is evaporated into aluminum gas and going to deposit on the surface when the cellulose film passes through the top of evoraption chamber. Now, more and more metallization plants are estabished in the land of china mainland, occupying the largest supply chain in the world of metallized films. So the produce of metallized cellulose film in china will be more cost-effective.
This film is ceritificated home compostable by third-inspection entity TUV, and you may get a sample film of our own for your own tests.
We hereby commit our film will be in compliance with FDA regulations, and thir-party inspection is available on customer’s request.
Metallized cellulose film can work as the reinforced middle layer in the multilayer compostable sachet packaging. When laminated, multi-funcations can be achieved to meet the very particular requirements for each product. In our plant, we are finalizing the laminate process in dry-laminate and solvent-less lamination, and going to achieve the final packages in a more sustainable way.
We are now achieving more gorgeous items based on the multilayer compostable foil of metallized cellophane film. You may learn more here.
Kraft paper works as outside print substrate, which is able to present a more eco-friendly appearance to the consumers, and this foil structure proves to be the most economical package based on metallized cellulose film.
When cellulose film works as the outside print substrate, it works like polyester film, including the matte lacquer. Complicated artwork will be printed on this foil with the highest standard.
Two layers of aluminumized layer are contained in this foil structure, with the aim of improving the barrier performance, to meet the very strict requirments for some sensitive products, like coffee beans, nutrition powder, milk powder etc.
PBS film works as the inner sealing layer, an improved compostable performance under home and garden conditions. This foil laminate should be taken as the true home compostable packages.
Similar to cellulose film, metallized cellulose will degrade quickly under nature soil condtions. The thin aluminumized layer will react quickly with water and oxygen to AlOx elements, which naturally exist on earth. So metallized cellulose should be taken as fully compostable and biodegradable.
Here we are going to perform our own test with sample film of metallized cellulose buried in our garden soil, and we will observe the degradation behavior with our own eyes, and let’s try to figure out the truth.
Along with the widespread of compostable packages in the consumer market, metallized cellulose film are now being more and more applied for the packages of consumer products.
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.
