Modern Logistics Promotes New Development of Packaging Engineering Subject (Part Two)

For the transportation of some large expensive instruments and equipments, if the smart packaging material ERF is used to design the transport packaging cushion support[4], on the one hand, the active vibration impact control can be realized according to the vibration and impact conditions of the circulation environment, and effective The cushioning protection function, in addition, such a buffer bearing can also be reused, the cost can be greatly reduced.
b. Green packaging requirements. From the perspective of the entire logistics process, only the packaging is so dependent on resources and thus affecting the human ecological environment. The packaging industry needs to consume too much resources and increase the input of goods. At the same time, packaging waste also causes environmental pollution. However, packaging is necessary for products, logistics, and activities. Therefore, studying the above-mentioned sub-effects of the modern packaging industry [1] has become a major issue, namely the study of green packaging. The greenization of packaging can be considered from two aspects. On the one hand, the resource requirements should minimize the shortage and the consumption of valuable resources; on the other hand, the packaging wastes have the least environmental pollution or can be recycled and regenerated into useful materials. Based on such requirements, garbage-free packaging such as pipeline transportation, live packaging for container transportation, reusable packaging of smart material ERF, and pollution-free packaging of degradable materials have been proposed.
c. Packaging system requirements; Packaging as an integral part of the logistics must be placed in the logistics system to study. If one-sided emphasis on saving packaging materials and packaging costs, although the packaging costs are reduced, but because of the low quality of the packaging, in the transport and loading and unloading handling and other logistics process caused damage, from the perspective of logistics system, but it is a waste. Because the packaging subsystem and the logistics system and other subsystems are interrelated and mutually restrictive, only the packaging subsystem, which is the basis of logistics, can be closely linked to them, and can create the best for the economic benefits of the logistics system. Condition [5].
d. Packaging standardization requirements. The standardization of packaging includes three aspects of standardization of packaging dimensions, standardization of products in the packaging industry, and standardization of packaging strength. Only the packaging specifications that are closely related to logistics efficiency are discussed here. The first criterion for determining the size of a package is the shape, weight, and volume of the product itself. However, when the logistics is studied as a whole, the size of the packaging must be adapted to the requirements of transportation, loading and unloading, and as far as possible, the specifications that are compatible with the collection and packaging of containers, pallets, etc. should be adopted. This just shows that packaging production (mainly referring to the specification size) determines the circulation, but also reflects the counter-productive effect of circulation on the production of packaging. Therefore, the logistics requirements for the standard size of the packaging, mainly reflected in the product size is smaller (including discrete bodies, powder, liquid and other intangible products) and packaging on the small package packaging. For this case (the reaction of circulation to the packaging production), first determine the logistics module (ie, the basic dimensions of the logistics container unit), and then divide the logistics module to obtain the package size specification series. In this way, the size of the packaged goods is not wasted when shipped, and there is a good stacking efficiency when the pallets are used for loading and unloading.
e. Requirements for convenient packaging. The convenient function is that the packaging itself should have, but in the logistics activities such as distribution, hooligan processing and other links, the higher requirements for the convenience of the packaging, namely, packaging, packaging, Kai Kai and reseal packaging, Simple requirements.
f. Requirements for rationalization of packaging. Reasonable packaging refers to adapting and overcoming various obstacles in the circulation process, adapting to the development of the market economy and continuously optimizing, obtaining optimal social and economic benefits, and giving full play to the useful functions of packaging entities [6]. In logistics activities, it must To rationalize the packaging materials, cost, quality, container structure, etc. The rationalization of buffer packaging is very important, because it can guarantee the safe transportation of products, and because of the simplification of buffer packaging, not only can reduce the corresponding packaging costs, but also can effectively use the packaging resources.
For transport packaging of fruits, vegetables, etc., the literature [7] proposes the law of linear cumulative damage, using the degree of damage to measure the transport safety of the packaging production, but as a complete logistics activity process, it is more reasonable to consider the price of goods. life.
4 Conclusion Throughout the role of packaging in the logistics and modern logistics on the packaging of new requirements, to make the package to serve the logistics, the packaging engineering discipline must be intelligent, green, systematic, standardized, convenient and rational In other directions.
