Abstract

The present invention relates to a corrugated cardboard forming apparatus for packaging used in a variety of packaging, in particular, in the construction of corrugated cardboard by interposing the corrugated medium located between the upper and lower surface paper of the cross-over multiple overlapping or overlapping the thickness of the box while compressing strength The present invention relates to a two-layer corrugated cardboard molding apparatus having an increased buffering effect, which minimizes the packing volume and effectively absorbs the impact from the outside applied to the package to more safely preserve the packaged contents.

Each of the winding rolls continuously feeding the first and second corrugated cores and one surface base paper wound in a roll state; A preheater for preheating each of the corrugated medium and the surface raw material supplied from these winding rolls to a predetermined temperature required for processing; A first one-sided corrugated cardboard forming means for processing the pre-heated corrugated core supplied from the first corrugated winding roll, and bonding the press to the surface raw material supplied by winding the press; The second corrugated core is processed from the second corrugated winding roll, and the second one-side corrugated cardboard forming means for processing the corrugated core to be bonded to the single corrugated cardboard by adhering the first corrugated cardboard on the surface base effectively absorbs the impact from the outside applied to the package. According to the present invention for safer preservation of the packaged contents, the entire packaging material is composed of recyclable paper without using heterogeneous materials that are the main causes of environmental pollution. By providing a high value-added packaging paper sheet, it not only significantly reduces the production cost of packaging materials, but also greatly contributes to environmental protection and resource recycling, and also effectively absorbs the impact from the outside on the packaging. To keep the contents safe Which it will have a variety of advantages, such as being.
