Product packing should be reasonably arranged

The packing arrangement of goods should be scientific. In general, it is a whole consisting of a certain number of commodities stacked in length, width, and height. It is packed in a box and forms a box. The sum of the flat areas on the six sides of the box is the “surface area” of the product, the size of the surface area, and the decisive role in the amount of packaging materials.
If the length, width and height are changed under the same conditions of volume and surface area, the material of the box will also change accordingly. In general, the width is less than the height or length of the packaging material; width is greater than the height or length of the packaging materials; the same width, length greater than the height of the material; the same width, height greater than the length of the province.
However, this is only a general principle, and specific packaging should also be considered based on the product. Items such as towels are put into the box, and the box type is “fixed in width and height, adjusted in height”; in the case of fragile goods, another method is adopted, such as the packaging of daily-use ceramics:
First, queuing different ceramic classifications and classifying them by the same calibre. Then, based on the categorized ceramic volume, we will study how many boxes are packed in each box so that each box can be loaded with full blows.
Second, according to the shape and size of the goods, they are staggered; while others use the vacancy between commodities to hide the handles, ears, and rings in the products and make full use of the capacity of the boxes to fill in the blanks. Measures to reduce the gap between goods, so that even if the goods are loaded flat, but also increased the pressure of the packaging box.
Set-to-shape products can use the product's own space to match the product's size and suit the product set. Using this method, not only can reduce the gap, prevent damage, but also can save materials, save shipping.
Such as jewelry boxes, enamelware, glass, can use the size of the product itself, take a small set of methods together. For some fragile products, it is necessary to strengthen the protection of the corners of the product and add some cushions to make the package flexible so that it can withstand a certain degree of impact.
Dismantling Some products that cannot be reduced in size by pressure, rational arrangement and suiting methods, because of their irregular size and large area, can be disassembled and mounted to reduce the volume. Such as: furniture, medical equipment, sewing machines and other products.
Reasonable Compression of Commodity Volume The packaging of bulky, light-weight, light-bubble products such as cotton, textiles, mats, drawnwork, fishing nets, feathers, bicycle tires, etc., is primarily intended to solve the problem of reasonably compressing the packaging volume. When pressing or pre-pressing boxes, it is generally based on the principle of not damaging the goods. That is, under the premise of protecting the quality of the product, the product volume can be compressed or packaged in a vacuum to save packaging materials and shipping costs.
Compression of the packaging volume with pressure, in the past, was performed using human and animal force compression. Now, mechanical compression is used more often, and compression with an oil press is the best. For example, sacks are packaged in bundles of 200 bundles each, and the stack thickness before unpressing is 1.7 m, after compaction is 60 cm, and after recovery is 90 cm. The size of the rebound has a lot to do with the properties of the tying material. If the rope is bundled manually after compression, the recovery rate will reach 50%. For example, if you pack with iron, compress the bundle, and the recovery rate is only about 5%.
Another way to compress the package volume is to use vacuum packaging. This kind of packaging is generally suitable for textiles, clothing, silk, feathers and other commodities. Textiles and clothing If you use a general compression packaging method, there are usually many wrinkles and creases, and it takes a lot of money to get it back to normal (restore).
In order to solve this problem, Sweden began to study this work in 1967, after years of practice and experiment, invented vacuum packaging technology. This is one of the most important innovations in the packaging field at the time.
