Research on the application of honeycomb panel in wood substitute pallets (I)

Abstract: China's wood resources are in doubt. Using other recycled citrus materials instead of wood packaging materials has become a new topic that needs to be solved urgently. Honeycomb panel is light in weight, good in compression resistance and earthquake resistance, and can also be used completely in urban areas. It is a new type of environmental protection material that replaces wood with paper. This paper analyzes the current situation of unpackaged materials at home and abroad, This paper expounds the structure and physical properties of honeycomb board, demonstrates the feasibility of replacing wood with honeycomb paper tray and the production process of honeycomb paper tray, and puts forward reasonable suggestions on relevant problems in production. At the same time, it expounds its own views on how to promote the goal of replacing wood with paper in the country; Substitute technique; Tray: using

honeycomb paper as a green packaging material, it has irreplaceable advantages compared with corrugated cardboard, technical materials and plastics. It uses paper instead of technology. A ton of honeycomb cardboard can replace 30 ~ 50 cubic meters of wood, and the cost is only one third of technical materials. The tray made of honeycomb paperboard has the characteristics of light weight, high strength, low cost and good cushioning performance. It can replace EPS white foam, eliminate white pollution and protect the natural environment. It is an environmental friendly new material that meets the development requirements of the 21st century. It is increasingly applied and promoted in the field of packaging at home and abroad

I. Development of wood pallets at home and abroad

pallets (also known as independent accounting boards for stack Finance) are a very important tool for modern industrial and commercial production, transportation, storage and packaging. Since the white bandit was born, there has been a hundred years' history of mechanical storage and transportation tools. According to historical records, the earliest debt transportation pallet. Gugan in the second half of the 19th century, at that time, it was only limited to the stacking of goods in factories and warehouses and short-distance handling

types of pallets in order to meet the needs of the characteristics of various goods loading, the pallet team has grown from small to large, and gradually developed into a large family with a wide variety. According to the use classification of pallets, they can be divided into disposable vulnerable and consumable pallets, operational pallets and warehouses used for joint transportation, special pallets used for short-distance storage and transportation in freight yards, platforms, docks and other internal pallets. They are disposable, generally simple and relatively low-cost, but the bottom pallet and Jack must comply with relevant regulations, In order to facilitate the forklift operation, the general-purpose tray generally needs to participate in the joint transportation. The requirements are relatively strict. In order to unify the management, the international standards organization (ISO) published the recommended standard of D tray in 1965, which includes the specification and size of the tray, the selection of materials, processing requirements and sexual test methods. The competitive tray is generally designed for the enterprise itself, which meets some mechanized loading and unloading, stacking operation services, and is easy to manage, Not easy to lose

there are various forms of pallets, and three kinds of pallets are commonly used, including flat pallets, home pallets and column pallets. At present, flat pallets are most widely used. Finally, according to different operation requirements and systems, flat pallets can also be divided into single-sided, double double double fork and four-way fork

the manufacturing materials and production processes of the tray are different according to the measurement verification conducted by the entrusted measurement department. The tray is divided into material, metal plastic tray and composite tray

specifications of pallets the specifications of pallets vary from region to region. The pallet specification recognized by the international organization for Standardization (ISO) is 1200 × 800mm Euro 1200 × 1o00mm parts of Europe, Canada, Mexico grid}1219 × 1016mm American specification; I1O0 × 1ioomm continental specification in these four kinds of pallets, the Asian specification pallet is recognized by matching with the ISO international container now rolling dry in the world, and is widely used for the advantages of honeycomb paper pallet

(1J green and environmental protection, can be completely recycled

(2) it is clean, moth free, and does not need fumigation and disinfection at all, which meets the requirements of the American market. Pharmaceutical and food industries can directly use

(3) it is flat and smooth, There shall be no debris, nails and other problems that may damage the goods, and the packaging of the load shall be protected to the greatest extent

(4) firm and reliable, with reasonable bearing structure, the maximum bearing capacity can reach 3 tons

(5) light and convenient. The average weight is only 6kg, which is 1/4 of the same wooden pallet, which is convenient for handling; And whether by air or sea, users can save a lot of freight and reduce product costs

(6) mitigate impact. Due to the use of honeycomb paper materials, relying on the advantages of honeycomb special stress structure, the product integrity rate is high

1。 Development status of wood substitute pallets in foreign countries

wood substitute packaging in developed countries mainly includes the use of high-strength multi-layer double arch corrugated boxes; Non wood pallets; The reinforced structural materials of edges, corners, bottoms and roofs, and the application of non lignified materials such as cushioning, positioning, protection and auxiliary materials used as partitions, cushions and filling, have entered the stage of commercial application as early as the mid-1980s. The substitute wooden pallet has attracted widespread attention because of its superior performance

wooden pallets are generally divided into honeycomb cardboard pallets, pulp molding pallets, paper filled pallets, plastic pallets, metal pallets, etc. They, together with the packing cases, as a whole of transportation and packaging, participate in the circulation process of high quality, which has a history of more than 20 years abroad. Although a certain amount of wooden pallets made of processed wood products such as fumigated and antiseptic wooden boxes and plywood are still used until now, substitute wooden pallets are gradually replacing wooden pallets. For example, Dr. Liu Yiwu of the Packaging Research Institute of Hunan University of technology used to make heavy-duty packaging boxes for small and medium-sized wood substitute cartons through automatic production lines, which are fixedly connected with wooden pallets at the bottom of the box. In recent years, paper pallets and non wood composite pallets have been gradually used. Honeycomb paper tray as a new generation of wood tray also plays a great role. Tinek company and Elis caliber pallet group company in the United States have the production and service business of honeycomb paperboard all paper pallets with waterproof treatment and protective packaging materials with cushioning performance used as box corners and bottom. At the same time, it can also be used as a cushion and partition board in heavy-duty packing cases, and cooperate with the inner wall of the box to be a wall panel material for load-bearing reinforcement

in foreign countries, the famous companies that produce modern wooden pallets include dura company in Canada, Einstein Engineering Co., Ltd. in Japan, plastic recycling center (cprr) in New Jersey, polymer IC inc.tx. in the United States, rimaplan Munich in Germany, smorgon consolidated Sydney in Australia, etc
