Furthermore, the surface paper and the bottom paper are both PP synthetic paper.
Further, the medium paper is insulating paper.
Further, the core paper is corrugated paper.
Furthermore, the reinforcing strip is made of TPU.
Furthermore, the elastic layer is made of a PP material, a PE material or a PVC material.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the carton paper is folded at the crease to form the carton main body, the reinforcing strip is reinforced at the crease through a hot melting process, and the reinforcing strip is made of TPU (thermoplastic polyurethane), so that the joint has elasticity and folding resistance, is not easy to deform and is not easy to damage; the core paper is in a wave shape, the elastic layer is compounded on the outer surface of the core paper, the core paper is similar to the spiral arrangement of the spring, the elastic layer is made of PP (polypropylene) materials or PE (polyethylene) materials or PVC (polyvinyl chloride) materials, and the PP materials or the PE materials or the PVC materials have elasticity, so that the core paper has high elasticity, namely the box paper has high elasticity, and therefore the corrugated carton which is not easy to deform and has high elasticity and pressure resistance is achieved.
