Honeycomb paperboard all-paper tray and manufacturing method thereof

Abstract

The invention discloses a honeycomb paperboard all-paper tray and a manufacturing method thereof. The honeycomb paperboard all-paper tray comprises a top board, bottom piers and a bottom belt, wherein the top board comprises a honeycomb paperboard base material, paper cardboards compounded on upper and lower surfaces of the honeycomb paperboard base material, and paper square tubes which are compounded at the periphery of the honeycomb paperboard base material; each bottom pier comprises a honeycomb paperboard filled block, an inner sleeve of the paper square tube and an outer sleeve of the paper square tube; the inner sleeve of the paper square tube is sleeved outside the honeycomb paperboard filled block; and the outer sleeve of the paper square tube is sleeved outside the honeycomb paperboard filled block and the inner sleeve of the paper square tube along a direction vertical to the direction of sleeving the inner sleeve of the paper square tube. The manufacturing method comprises the following steps of: manufacturing the top board; manufacturing the bottom piers; manufacturing the bottom belt; and adhering various bottom piers on the same bottom belt at intervals to form a bottom pier assembly, and parallelly adhering one end of each of the various bottom piers which is not adhered with the bottom belt to the lower surface of the top board. The honeycomb paperboard all-paper tray meets the requirement on environment friendliness, and has the advantages of low cost and high compressive strength and bending resistance.

Description

technical field [0001] The invention relates to an all-paper tray and a manufacturing method thereof, in particular to a honeycomb cardboard all-paper tray used in the packaging and transportation industry and a manufacturing method thereof. Background technique [0002] Previously, shipping pallets were generally made of wood, plastic and metal materials. Plastic transport pallets are restricted and banned due to environmental protection requirements, especially in export transport packaging; metal transport pallets can only be used on special occasions due to their high production costs. Since forest beetle disease was discovered in the United States, the United States, Canada, the European Union and other countries have strictly restricted the use of wood packaging in China, and the export of wood packaging must go through strict fumigation and quarantine, which is cumbersome and greatly increases the cost of packaging and transportation. In addition, my country's nation...
