We are first developed single-layer biodegradable sanitary packaging capable of multi-color printing and successfully commercialized in Austrial. In addition, through the upgrading of technology, formulation and process, we also developed the thinnest 50 microns of double-layer laminated degradation packaging and 3-layer paper&plastic laminated degradation packaging. The upgraded packaging solved original difficulties of easy to scratching and ink missing, and improved black dots caused by printing. At the same time, all the glue, ink and paper ued in the packaging meet the degradation standards of Europe, the United States, Australia and other relevant countries.
