Description

  • Field of the invention
  • The present invention relates to the technical field of packaging for the electrical and mechanical products, in particular a paper honeycomb corner protection and the method for their preparation.
  • Technical background
  • The paper honeycomb board is a new environmentally friendly packaging material in China, which can often be used as the packaging for various goods, especially as the export packaging for the electrical and mechanical products. The honeycomb panel has a great importance in environmental protection and the rational use of resources, the reduction of "white pollution", the avoidance of "overpacking", the promotion of "saving with wood". At the same time, the honeycomb panel has a direct influence on the reduction of years of enormous economic losses caused by improper packaging. If the annual direct or indirect reduction of the influence of the foreign technical barrier and the green barrier on the export goods of $ 24 billion is 30%, China's annual export losses will be reduced by $ 7.2 billion.
  • From the Chinese Patent Application 200710030873.7 is known "a paper corner protection, comprises a base body ( 1 ) having an L-shaped cross-section, characterized in that the base body ( 1 ) by an outer corner plate ( 11 ) and an inner corner plate ( 12 ), the outer corner plate ( 11 ) is a hard plate and the inner corner plate ( 12 ) is a paper honeycomb panel, the connection between the outer corner plate ( 11 ) and the inner corner plate ( 12 ) is achieved by adhesive ". By adopting this structure, good compressive strength and buffering are realized, and the packaged goods are better protected, but the manufacturing cost of the L-shaped paper honeycomb corner protector is very high, and the used amount of the paper honeycomb board is also very large, therefore this is Process disadvantageous in the costs compared to the traditional EPS packaging used, and in storage and transport, the space requirement is very large because of the single structure, thereby increasing the cost of transport.
  • US Pat. No. 6,561,357 B2 discloses a one-piece protector which may be stacked or nested in an unfolded position and then folded for use in the desired shape and made substantially from a rectangular laminated sheet. The blade has an outer wall and an inner wall which are connected by a longitudinally from top to bottom extending pivotable portion, and wherein the hinge portion having a plurality of longitudinal folds or notches. The sheet is made of several laminated layers.
  • US 3,887,418 discloses a method for the continuous production of a low density honeycomb core for use in lightweight sandwich panels and laminates. Thin sheets of structural material, such as aluminum foil or kraft paper, are first corrugated into bumps and trough-forming areas, followed by the application of adhesive coatings, for example to the outer surfaces of the ridges and troughs of the layers of corrugated webs. The layers are then stacked so that an adhesive coated corrugated web alternates with an uncoated corrugated web. Heat and / or pressure is then applied to the stack to effect bonding of the stacked material. Expansion of the stack by pulling the outer webs of the bonded stack creates a low density honeycomb core.
  • U.S. 3,086,899 discloses a composite construction laminate and laminar and cellular wall structures consisting of layers of stackable layers consisting of parallel regions of regularly arranged rectangular depressions in the form of connecting elements, the structure being composed such that the connecting elements of the individual juxtaposed layers are continuously intermeshed.
  • US 1,184,968 describes a protective device for contact surfaces of stacked bricks.
  • US 520 366 describes a packaging material comprising two or more superimposed layers of corrugated paper, the corrugations of the layers being arranged diagonally and being superposed at opposite angles of the opposite sides to obtain the greatest possible number of points of contact.
  • GB 2 321 032 A discloses an edge protector for the edges of rolled moldings, for example pallets, wound steel and paper products, made from a roll of elongated sheet of plastic material, the sheet having a longitudinal notch along a major surface which extends only partially across the thickness of the sheet , The indentation divides the sheet into webs which are folded in an L-shaped edge protector.
