Overview of export packaging of large-scale equipment in Germany

I. preface

as one of the world's major industrial countries, Germany is a world-famous exporter of mechanical and electronic equipment. In recent years, a large number of German large-scale equipment and complete sets of production line equipment have been exported to China across the sea, involving automotive, petroleum, chemical, steel, machinery, electronics and other industries. How to ensure the safe arrival of these large-scale equipment and complete sets of equipment at the location of users in China or other countries is an important issue for German production enterprises and transportation and packaging enterprises. This paper introduces the methods of export packaging of large-scale equipment in Germany based on what the author saw in securitas, Hamburg export packaging Co., Ltd

II. Packaging method

"securitas" is located in the free port of Hamburg, Germany, which is extremely convenient for shipment and transportation. Moreover, the company has a history of more than 40 years in the packaging of machinery and equipment, so many famous German and European companies are willing to hand over their equipment export packaging to "securitas", In recent years, more than hundreds of thousands of tons of large-scale equipment have been shipped to China after being packaged by "securitas" of Hamburg export packaging Co., Ltd. the company commonly uses two methods of equipment export packaging, namely, box packaging and open packaging

(I) boxed

"securitas" large-scale equipment export packaging mostly uses ordinary closed boxes, and the packing wooden boxes are generally made of pine, which mainly reflects that the base composed of skid, end wood and bottom plate, as well as the frame structure of top cover, side and end face, as well as the beam and beam support are all made of pine. Most top plates, side plates and end plates also use pine boards, and sometimes a certain amount of ordinary plywood and a small amount of oriented strand board (OSB) are also used according to customer requirements

when packing in wooden cases, first select appropriate skids, end logs and base plates according to the weight and size of the equipment, and then drill corresponding holes on the base according to the position of fixing bolts or screws. Next, lay a layer of foamed plastic film on the bottom plate, then a layer of polyethylene plastic film or aluminum-plastic composite film, and lay a layer of foamed plastic film again at the place where the equipment contacts the film, so as to prevent the base or equipment from damaging the surface of the plastic film or composite film, thereby affecting the packaging protection effect. Finally, hang the equipment on the base paved with film, complete the protective packaging such as film heat sealing and fasten the equipment on the base, then nail the beam support on both sides of the base, set up the cross beam, and use steel nails to fix and connect the end plate, side plate and top cover respectively, so as to complete the whole wooden box packaging

(II) open packaging

in addition to box packaging, another equipment packaging method often used by "securitas" is open packaging. Open package refers to the package with no side plate, end plate and top cover, but only the base. Here, the equipment is only fixed on the base, and the equipment is not packed in boxes, but the production process of composite materials is still complex. Simple packaging or partial packaging, such as plastic film, is carried out. This method can save packaging costs for packaging products with low storage and transportation requirements

the packaging process of open packaging is basically the same as that of box packaging. First, drill screw holes on the processed wooden base, lay a layer of foamed plastic film on the base, and then lay a layer of vapor corrosion inhibitor. The place where the equipment contacts the vapor corrosion inhibitor film is padded with a layer of foamed plastic film, and the whole equipment is sealed with vapor corrosion inhibitor film, and then fasten the equipment on the base by various methods. Next, cover a layer of heat shrinkable film from top to bottom, nail the edge of the film around the base with narrow thin wooden strips, and finally heat it around the package with a burning nozzle, so that the outer film shrinks to complete the overall packaging. Such packages are usually loaded and fixed in containers for transportation

(III) pretreatment of wood before packaging

in order to protect China's forest resources, ecological environment and tourism resources, the state has set a relatively small pull. Relevant departments have put forward requirements for wood packaging exported from EU countries to China. All wood packaging exported from EU countries to China must undergo heat treatment, fumigation treatment or other effective pest control treatment recognized by China before export, "Securitas" adopts the method of heat treatment for wood packaging exported to China, that is, the central temperature of wood reaches 56 ℃ and remains for more than 30 minutes. After packaging, the wood package shall be sprayed with marks including wood pretreatment method, treatment location and other information as required

III. protective packaging

for large equipment, its protective packaging means that the packaging should protect the equipment from damage due to the influence of climatic load and mechanical load. Compared with other packaging products, the most important protective packaging of large equipment is rust proof packaging and safe transportation

(I) anti rust packaging

the temperature and humidity changes during transportation have a great impact on the equipment. The temperature difference from dry and cold climate to hot and humid places, or between day and night, will lead to the formation of a layer of condensate on the surface of the equipment. If anti rust packaging measures are not taken, the metal surface of the equipment will rust

"securitas" uses two anti rust packaging methods. One is the desiccant method, that is, hang a certain amount of desiccant in a closed space of polyethylene plastic film or aluminum-plastic composite film, and absorb the moisture in the film cavity during storage and transportation, so as to achieve the purpose of rust prevention. During operation, the bagged desiccant must be hung around the equipment evenly and cannot be placed on the equipment casually. Dry polyurea stands out from many waterproof materials before heat sealing. The drying agent bag should not be exposed to the air for too long. No cracks or small holes are allowed on the surface of the film after heat sealing, and the place where the anchor bolt passes through the film shall be sealed with a rubber sealing washer. Before sealing the whole film, leave a small opening to drain the air in the film cavity, and finally heat seal this opening. This anti rust method is mainly used for packing, and the packing box is often exposed during storage and transportation, without the protection of containers, etc. In order to prevent rain and water, a layer of waterproof paper should be added to the inner side of the end plate and side plate of the wooden box, and a layer of waterproof felt should be sandwiched inside the top cover. After the box is packed, a layer of sun proof and rain proof plastic film should be nailed outside the top cover

another anti rust packaging method used by "securitas" is the vapor phase anti rust method, which mixes a special solid material into paper, plastic film, buffer materials and other carriers. In the process of storage and transportation, this special solid material will become gas molecules to cover the metal surface to form a protective layer, so as to prevent oxygen and water from reacting with the metal to produce corrosion. What the company uses most is the green film, which is a vapor phase rust preventive material and can be used as an ordinary plastic film. Its color is mainly to distinguish it from ordinary plastic film. The packaging process of vapor phase antirust film is the same as that of ordinary plastic film, except that desiccant is not used in the enclosed space, but several strips of vapor phase antirust foam materials are hung on the equipment. Sometimes, in order to prevent the solidified water from accumulating at the bottom of the film, a small crack can be drawn on the vapor phase antirust film at the lowest position in contact with the base, so that the water can leak out in time. The sealing of the vapor phase antirust film is usually not as high as that of the desiccant method. This method is generally combined with heat shrinkable film, and is mostly used in open packaging

(II) safe transportation

if the equipment is not well fixed on the wooden base, the impact and vibration during transportation and loading and unloading will cause the equipment to slip, collide or overturn, resulting in equipment damage. In order to prevent such problems during transportation, the equipment and some packaging auxiliary materials must be fixed on the base. The most common is to fix the equipment directly on the sleeper or skid of the base with bolts, or use safety strapping to fix the equipment on the base, or use wood strips and blocks consistent with the outline of the equipment to clamp the equipment with steel nails or bolts, or use wood strips as pressure bars and fastening screws to fix the equipment, and the method used depends on the specific situation. In addition to these common methods, "securitas" also adopts the method of increasing the friction coefficient between the equipment and the base, for example, adding a layer of rubber material between the two. This method of increasing the friction coefficient, for example, adding a layer of rubber material between the two. This method of increasing the friction coefficient is also suitable for the transportation package and the bottom plate of the transportation tool

IV. conclusion

as the largest port machinery and equipment packaging enterprise in Germany, securitas has had a great influence in Germany and Europe after years of continuous development. The company has accumulated rich experience in the field of export packaging of machinery and equipment, and many practical and effective things are worth learning and learning from domestic peers

in recent years, the export of China's mechanical and electrical products has been in a good upward momentum. With the continuous development of China's modern technology and the introduction of a large number of foreign capital and foreign technology, our equipment manufacturing industry will have greater development. German friends often say that if Germany exports equipment to China now, it will turn the other way in ten or twenty years. Therefore, we should constantly improve the packaging technology of equipment export from now on, improve the quality of equipment export packaging, and lay a good foundation for more equipment export in the future
