A few days ago, Treo-fan of Germany developed a new product of biodegradable metallized polylactide (PLA). This product has significantly reduced fragrance, oxygen, and moisture permeability compared to products that do not have a metallized film. The metalized PLA film Biophan is suitable for the packaging of foods with high fat content, such as butter, dried cheese and various kinds of candies. Its appearance is as bright as a mirror, and it has high barrier properties required for food packaging. The company is also currently developing products with higher barrier properties, allowing Bio-phan films to be used for the packaging of fresh foods such as meat and fish.
It is reported that this metal-plated biodegradable film can meet the EU (EU) and US FDA specifications on food-contact materials, and has also passed the relevant certification of the German Industrial Standard (DIN). Treofan expects that Biophan and paper composite packaging will have a promising future in the candy market and can also replace aluminum-containing composite packaging. The good hydrophobicity of the film is also very suitable for this application. The company's test results show that at 23% and 50% relative humidity, the material's oxygen transmission rate is only 1/12 that of the unplated PLA film, similar to metal-coated polypropylene film, higher than metal-coated glass paper. .
