1. Kunshan carton thickness application:

　　1. AA reinforcement is a common type, thinner than 2mm, a little softer, suitable for products that do require high packaging. Guangzhou carton recommends to choose this if the requirements are high.

　　2, KA has good hardness high cost performance, which can be used for most packaging.

3. KK is a very hard type feels very good.

The thickness of the 3-layer carton of the Kunshan carton manufacturer is: if it is B corrugated, the thickness is 2—2.5mm, the feel is relatively hard. If C corrugated is used, although it is the same material as B corrugated, it has a higher degree of pitting. The gap is larger than that of B corrugated, so the hand feel is as strong as B corrugated, but the thickness is 2.5-3mm. After processing, the edges will be compressed. 3 layers are 2-2.5mm. All 5 layers are made of BC corrugated. The thickness is 5mm. After processing, the edges are 4-4.8mm. It is like cutting bread. Although the edges will be compressed, the thickness in the middle has changed. .

2. The relationship between carton thickness carton quality

Generally, the higher the hardness, the better the quality. Thickness material are the two key factors that determine the hardness of the carton. There are usually three-layer five-layer cartons, of course there are thicker seven-layers. The more layers of the cartons, the thicker they are. Three layers are Simple three-layer flat board, but two-layer flat board with a layer of corrugated in the middle, five-layer flat board with three-layer flat board double-corrugated; three-layer five-layer cartons are also listed as corrugated double-corrugated boxes; there are also many kinds of carton materials, good The material is only high in hardness, but also light in weight. Inferior materials are often very low in hardness easy to deform; the material of the carton on the market is "KK>KA>KB>AA>AB>BB" high to bottom, KK material is The current good material, the thickness of three layers is enough to carry the weight of a normal adult year, the surface is smooth textured, KK is good, but the price is also the most expensive, AA, BB materials are slightly harder, but with five layers The thickness hardness are high enough to protect the product damage. Huadu Carton Factory recommends that sellers choose different types of cartons according to their needs. For example, five-layer AA cartons can be used for fragile valuable items, ordinary items that have been dropped, the product itself comes with a carton. Choose three-layer cartons. enough.
