Description

Honeycomb carton turns over a connection structure

Technical Field

The utility model belongs to the technical field of the carton and specifically relates to a honeycomb carton turns over a connection structure.

Background

The existing cartons are generally made of corrugated boards, and the corrugated boards are in a transverse wavy structure, are not pressure-resistant and easy to deform, so that the corrugated cartons made of the corrugated boards are not high in performance, and some manufacturers can use honeycomb paperboards to make the honeycomb cartons.

The honeycomb paperboard has the following characteristics:

(1) light weight, less material consumption and low cost. Compared with other various plate structures, the honeycomb sandwich structure has the largest strength/mass ratio, so that the performance/price ratio of a finished product is good, which is the key for successfully spreading the honeycomb paperboard.

(2) High strength, smooth surface and difficult deformation. The honeycomb sandwich structure is approximately isotropic, the structural stability is good, the honeycomb sandwich structure is not easy to deform, and the outstanding pressure resistance and bending resistance are the most important characteristics required by box-type packaging materials.

(3) The impact resistance and the buffering performance are good. The honeycomb paperboard is made of a flexible paper core and surface paper, has good toughness and rebound resilience, the unique honeycomb sandwich structure provides excellent buffering performance, the honeycomb paperboard has a higher energy absorption value per unit volume in all buffering materials, and the high-thickness honeycomb paperboard can replace EPS plastic foam cushions which are widely used at present.

(4) Sound absorption and heat insulation. The honeycomb sandwich structure is internally provided with closed cells which are filled with air, so that the honeycomb sandwich structure has good sound insulation and heat preservation performance.

(5) No pollution and conforms to the modern environmental protection trend. The honeycomb paperboard is made of recyclable paper materials, and can be recycled completely after being used.

Although the existing honeycomb carton utilizes the honeycomb structure of the existing honeycomb carton to improve the compressive strength of the carton, because the side wall of the existing honeycomb carton and the turning structure formed by flat pressing the turning pages at the bottom or the upper part of the existing honeycomb carton are easy to damage the strength due to the connection structure between the turning pages at the bottom and the side wall through slitting and pressing line grooving, and then the honeycomb carton for containing articles can not meet the requirement on the bearing capacity of the carton in the storage process.
