What material is the packing bag for pure milk, please?
General milk packaging is basically Tetra Pak packaging or Kang Mei package, aluminum foil about 5% of the quality of the entire package, about 79% of the paper, polyethylene layer of about 16%. Because the aluminum foil, polyethylene layer and paper layer are bonded by hot pressing or adhesion, it is difficult to separate the layers. Learn1986 (in station contact TA) these two documents may be useful to you.
W1l203 (station contact TA) should be food grade polyethylene, safe, easy to tear learn1986 (station contact TA), aluminum foil and polyethylene plastic film and paper interaction combined into polyethylene aluminum plastic composite packaging materials.
