Rubber pads or polystyrene foam pads should be placed between the product and the bottom of the box. After checking that there are no missing objects, the box can be closed and stuffed with fillers according to the requirements of 5.3.2.3, and then covered and nailed according to the design requirements. At the same time, the eight corners should be reinforced with angle iron. The selection of steel nails should comply with the provisions of GB349. 5.4.2:2 When small products are packed in corrugated boxes or calcium plastic corrugated boxes; put the inner packed products into the box, fill the gaps with clean filling paper, and close the cover, and use 60mm wide tape to seal the interface to both ends of the interface and extend to half to one third of the height of the two sides. After weighing and recording, the packing list shall be attached to the appropriate position on the side. Then use nylon strapping tape to tie twice, or tie into the shape of "#". The strapping tape shall be overlapped firmly, moderately tight, flat and not twisted. 5.4.2.3 When small products are packed in wooden boxes, put the inner packed products into the box, fill the gaps with clean filling paper, cover and nail them tightly, and then tie them twice with oxidized steel straps. The steel straps shall be overlapped firmly and nailed at two places on each box board. After weighing and recording, the packing list shall be attached to the appropriate position on the side. 5.4.3 The accessories and spare parts of large products shall be packaged in plastic bags (the accessories and spare parts of humid tropical products shall be added with appropriate amount of moisture-proof agent), and then packed into the outer packaging box together with the products. When this is not possible, they shall be packaged separately and shipped together with the products. 5.5 Random documents
5.5.1 The documents supplied with the product should generally include the certificate of quality, instruction manual, principle and installation wiring diagram and other documents. 5.5.2 All random documents should be put into paper bags, and then the paper bags should be put into plastic bags.
