The 350g kraft paper used in the 350g kraft paper box is a medium-high gram weight kraft paper. Whether it is hardness or stiffness, it is significantly better than 300g kraft paper. The core advantage lies in its high strength and environmental protection. The high strength is reflected in its excellent compression and puncture resistance, and it can carry 3-8kg objects. The environmental protection performance is that it can be 100% degraded and mass production will not affect the environment. It is suitable for a variety of packaging needs, including moving, logistics transportation, commodity packaging, etc.
The sizes of 350g kraft paper box vary, and the following three are common:
300mm×200mm×150mm in size, suitable for packaging small electronic products, cosmetics, stationery, etc., with a load-bearing capacity of 15-20kg;
400mm×300mm×200mm, 500mm×350mm×250mm in size, commonly used for packaging clothing, small daily necessities, food, etc., with a load-bearing capacity of 20-30kg;
600mm×400mm×300mm, 800mm×500mm×400mm in size, used for packaging larger home appliances, furniture accessories, sports equipment, etc., with a load-bearing capacity of 30-40kg.
The above sizes are more common in daily life, and we can also customize them according to customer needs.
The load-bearing capacity of 350g kraft paper box will change under different humidity environments. The higher the humidity, the more obvious the decrease in load-bearing capacity, which is related to the material characteristics of kraft paper.
The moisture in the air will gradually be absorbed by the kraft paper, and the fibers in the kraft paper will absorb moisture and expand. At the same time, the bonding force between the fibers will weaken, resulting in a decrease in the strength of the kraft paper and a decrease in the overall load-bearing capacity of the carton;
The moisture in the kraft paper will gradually dissipate and become dry. When subjected to external force, the fibers are easily broken, thus affecting the load-bearing capacity of the carton;
350g kraft carton can maintain good performance, the fibers are in a relatively stable state, and the carton can reach its designed load-bearing capacity.
For the convenience of users, the size specifications can be customized.
