Making milk packaging containers with EPS

Milk packaging containers made of polystyrene have also recently developed. A new milk package consists of three layers of polystyrene, the middle layer is foamed polystyrene, and both sides are covered with the same kind of non-expanded polystyrene. Because the interlayer styrofoam is filled with air, this packaging structure has excellent thermal insulation properties. In addition, the middle layer can increase the strength and rigidity of the material, and it maximizes the saving of raw materials. Since the surface of polystyrene is white and smooth, it is possible to carry out color printing of delicate patterns.
