Corrugated carton packaging and its practical program (4)

See examples of modest packaging of corrugated boxes to see how to suppress excessive packaging.

(I) Carton reduction and convenient packaging

When designing, attention should be paid to the opening and closing of the packing box, folding and stacking in the form of a flat plate, and the whole is convenient for combination operation; the portable part is firm and durable; the volume in the transportation process is as small as possible, which can reduce the cost and improve the transportation efficiency.

1. The design of packaging structure is simple and reasonable, which is conducive to folding, opening and closing, folding and storage, such as the design of various convenient cartons. Easy to open the box and easy to handle.

2, low cost. Convenient packaging uses less raw materials and can be made from recycled paperboard to make simple cartons and cartons.

From a long-term point of view, we must design packaging around the purpose of environmental protection. It is also a plan for the human ecosystem, and it should not cause excessive resource extraction and waste. There is no contradiction between quality and convenience. Convenient packaging can not only reduce costs, but also protect the environment. The use of simple design and low-consumption design is appropriate. It is a change in the concept of consumption, and it is also the development of market circulation. Packaging design is to guide and lead people in this situation. consumption.

Many countries in the world are advocating "moderate" packaging, reducing packaging as an important measure to achieve green packaging, this new idea is also called "green design." The reduction in packaging awareness has been strengthened, and reductions in packaging have resulted in a reduction in waste, which is the preferred approach for green packaging. This awareness has been strengthened in China in recent years. Many reduced packaging products have been designed; for example, the performance of the material is improved, the strength of the bottle container is improved, the weight of the thin wall is reduced, and the double-arch composite cardboard is used to ensure the strength of the carton. At the same time, the thickness of the paperboard is reduced by 30%; in another example, for the transportation and packaging of many products, the amount of material is greatly saved by improving the packaging structure and the cushioning pad design.

(B) The principle of low weight, high strength and light weight

Low-weight, high-strength, lightweight base papers provide new solutions to over-packaging.

The practical experience of many companies shows that the application of low-weight, high-strength base paper can not only ensure the compressive strength of the carton, but also reduce the amount of raw paper, improve the rate of paper out of the unit, reduce the cost of the carton, so especially by the terminal companies The user's favor. Through the change of the box design, the five-layer box into a three-tier box, etc., can effectively reduce the packaging cost of 5% to 15%. Saving paper consumption also saves storage space. Considering that the price of paperboard paper and liner paper market is significantly higher than that of core paper and corrugated paper, the weight of paperboard and paperboard should be properly reduced, and the weight of paperboard and corrugated paper should be increased to reduce the cost of paperboard and improve the resistance of paperboard. Degree of performance indicators such as the purpose. For the carton enterprises that make home appliance packaging, to minimize the weight of the original paper on the basis of guaranteeing the quality of the carton, it can not only win the user's order but also reduce the product cost.

(c) Advantages of micro-tiles

As the fine corrugated packaging has the advantages of high compressive strength, exquisite printing, etc., it has been recognized by the users, and the dosage has been growing steadily. Nowadays, there are many domestic enterprises that use E楞. For example, Siemens and other large companies have already put forward requirements for using finer and smaller files such as G楞.

1. Compared with solid cardboard, the micro-twisted package saves 20% of the cost. Compared with solid cardboard, the low-weight, high-strength micro-corrugated cardboard box has a better cost performance, thus making the packaging cost more economical and reasonable. Under the same conditions of use, micro-twisted packaging is characterized by its low weight and high strength, which is in line with the current trend of "lightweight" packaging.

2. Compressive and breaking performance is more prominent. While reducing costs, the fine corrugated packaging also ensures superior performance in all aspects of the carton. Compared to large-size packages such as B-type, micro-corrugated packages have lower cassette heights, more unit area turns, denser cassettes and stronger structures, so when using the same base paper and the same pressure, it In the parallel pressure of the pressure strength and buffer capacity and other advantages are more obvious, such as the E楞 box rupture strength can reach 11kg/cm2. The pressure capacity of the outer packaging of a general paper product is at least 7-8 times the weight of the package.

(4) Reuse of packaging waste

The reuse of packaging waste also plays a significant role. The use of waste corrugated paperboard, cornerboards, etc. through the subsequent processing steps (mainly paste, cutting and forming) into the packaging seats, liners, jackets, etc., instead of EPS foam, with its low cost, excellent effect and other characteristics have become reduced packaging The new highlight of cost has realized a further drop in packaging costs while improving the quality of packaging.

The United States, Japan, and other industrialized countries have vigorously advocated "moderate packaging" and reduced "excessive packaging" in the packaging of goods. Many large companies use packaging reduction as the goal of their own work. For example, Matsushita Electric Co., Ltd. requested to reduce 30% of EPS buffer material usage within two years. China is also actively developing substitutes for foaming agents, and uses natural cellulose, lignin, etc. as raw materials instead of EPS to research and develop the structure of pulp enhancers and corrugated boards to increase the strength of packaging paper and paperboard and reduce the use of cardboard. Thickness, thus reducing packaging.
