Extension of corrugated and composite paperboard products (4)

The use of corrugated paperboard trays can reduce transportation costs.

A standard wooden pallet weighs about 27 kilograms, while a paper pallet weighs only about 4.7 kilograms. This means that each truck can hold 850 kilograms of cargo and it is easy to carry. In addition, the paper tray has no slivers of trees, no fixed nails and rough corners, and no toxic chemicals left on the oak trays when fumigated, so it does not pollute the environment and harm the human body. And can be recycled, easy to handle.

Like all three-layer corrugated cardboard, pallets are made of A-type corrugations and have a good ratio of strength and weight. The three-layer corrugated cardboard tray is generally the same strength as the wooden tray, and weighs only 20% of the wooden tray.

In short, the topless cardboard pallet is now the most widely accepted and used packaging in the fruit and vegetable industry in Europe and abroad. After the fruits and vegetables are packaged in the grower's packaging workshop, they can be delivered to the supermarket and moved to the shelves in good condition. It is welcomed by both producers and consumers. It is not only convenient to transport but also can display products better.

Alternative appliances for green packaging of EPS foam plastic

According to the relevant information, since the second half of the previous year, Kelong, Changhong, Haier, Hisense, Aucma, Gree, Midea and other famous brands of domestic and foreign companies have also adopted corrugated composite honeycomb paperboard materials instead of EPS foam plastic liners and wood. Tray, with the international market. The use of corrugated composite honeycomb paperboard materials not only reduces the packaging cost (the cost of packaging each cabinet air conditioner is reduced by about 15-20 yuan), but also eliminates the "white pollution" and opens up a smooth export of foreign trade enterprises' products. "Green channel".

The reuse of packaging waste also plays a significant role. The use of waste corrugated cardboard, corner board, etc. through the post-add 2ET sequence (mainly for bonding, cutting and forming) into the package seat, liner, jacket, etc., instead of EPS foam, with its low cost, excellent effect and other characteristics become lower The new highlight of packaging costs has achieved a further drop in packaging costs while improving the quality of packaging.

Through the redesign of packaging and the research and development of new materials, Skyworth Group has adopted a self-developed packaging method combining corrugated paperboard and honeycomb paperboard to reduce its own packaging cost by 20%. TCL has begun to improve the design of the carton. After the improvement of the paper type, weight, box type and liner material, the cost has been reduced by about 10%.

Taking the improvement of the design scheme of the outdoor machine corrugated cardboard packaging box of Hisense Home Air Conditioning Products as an example: The design of the corrugated cardboard box of the air-conditioning outdoor unit is optimized to keep it fixed and protected; the function of the middle parts is simplified, and the side of the protective product is simplified; Hit the part.

The paper machine profile of the outdoor machine is gentle; the middle liner structure is mainly divided into three parts: upper, lower, and left and right, and each of the three parts has its own emphasis. The underliner is responsible for the bottom surface of the empty adjuster; the center punch and the lower half of the positioning function require higher strength. The factory adopts the combination of corrugated composite paper honeycomb liner and paper type steel to form a tray-like tray. Body, with the bottom structure of the whole machine, to achieve slow; medium, supporting role.

For lighter outdoor units, the left and right cushions may not be used, and the positioning and ease of protection in several directions may be achieved through the cooperation of the structure of the lower cushion and the upper cushion.

This packaging scheme not only reduces the material cost of corrugated board for the production enterprises, but also promotes the various aspects of product circulation, the parties involved, and the relevant personnel to standardize their own work and management level, and in particular can reduce the rough handling. In addition, the reduction in the use of corrugated paperboard is very significant for the current environmental protection, avoiding over-packaging, and our country's annual output of nearly 20 million sets of split air conditioners, which alone can reduce the consumption of corrugated board by nearly 32,000 tons per year. .

Application example of full-paper high-strength "Wazhongwa"

After long-term development and repeated trials, Guilin Paper Products Packaging Factory has developed a full-paper, high-strength, reinforced sandwich corrugated board (abbreviated as “Wazhongwa”), and uses this cardboard as a shockproof and pressure-resistant packaging carton and reinforced structure. Combination packaging containers and snap-on, plug-type connection devices. The above products have broken through the limitations of traditional corrugated packaging and honeycomb paperboard technology. From the appearance to the internal quality, they have promoted the technological leap of packaging products, providing packaging companies and manufacturing industries with a broad space for development and profitability. Its comprehensive advantages are as follows:

Change the wood product packaging, high cost, waste, difficult to recycle, and poor shock resistance, heavy, difficult processing and other defects, easier to quarantine than wood product packaging, safety is good

To solve the fragile, afraid of pressure, bulky or expensive items using foam plastic shock pressure caused by a large number of white pollution, is a pure green packaging;

祛 In addition to the low strength of traditional corrugated packaging paper products, the disadvantages of pressure resistance, breakage resistance inferior to wood, anti-needs and anti-pressure are weaker than those of foamed plastics;

By changing the fatal defects of the traditional "honeycomb paperboard" with shrinking tides and unpredictable gravity, the pressure loss of the packing box during shrinkage and deformation during storage and transportation in humid climate can be avoided.

It is a brand-new solution to meet the needs of large and heavy household appliances. It is a packaging revolution that replaces wood and replaces foam technology. The wide application of corrugated cardboard and its products is one of the important ways to realize paper-based wood.
