Although the use of packaging cartons is all as packaging materials, there are still differences in their uses. Different packaging products have different requirements in terms of quality. Make sure what they are used for when buying, and make cartons of different quality according to the needs of use, which will ensure the quality of transportation, packaging and delivery.
The packaging cartons for different purposes are made of different materials. For example, corrugated boxes have three layers, five layers and seven layers. And what kind of material to choose according to the bearing capacity of the carton. At this time, we should also observe whether the material is turbid, whether the material with impurities is relatively clean and whether the texture is strong.
In addition to the above two points, it is also important to check whether the indicators are up to standard. The lateral pressure and compressibility of cartons are test standards, and cartons that meet these standards are beneficial to the use of cartons in all aspects.
