In addition to protecting goods and facilitating storage and transportation, cardboard paper boxes also play the role of beautifying and promoting goods. Cardboard paper boxes belong to green products, it is conducive to environmental protection, loading, and unloading transportation. The next will provide you with a detailed introduction to cardboard paper boxes.
Here is the table of contents:
How is the strength of cardboard paper boxes designed?
What are the design principles of the cardboard paper box?
1. Side compression strength = surface raw paper comprehensive ring compression strength + comprehensive corrugated paper ring compression strength * shrinkage rate general side pressure calculation according to the lowest ring compression strength of raw paper (safe and reliable), the actual test value will be appropriately greater than the theoretical calculation value.
2. Breaking strength: The maximum external force that a unit area of corrugated board can withstand before rupture is uniformly increased. Unit: Kg/cm2.
Cardboard paper box rupture strength = face paper rupture strength + middle grid paper rupture strength + bottom paper rupture strength
4. Side compression, breakage resistance, puncture with cardboard. Cardboard paper box edge compression strength will be lower than the cardboard edge compression strength (due to the loss of corrugated in the manufacturing process).
5. Cardboard paper box compressive strength = side compression strength (N/cm) * Calicut constant F. The F value depends on the perimeter length of the cardboard paper box, 2*(length + width) cm. and the corrugated flute type.
6. The compressive strength of cardboard paper box = corresponding to the compressive strength of ordinary box type * 0.6 * 1.62 * shaking cover width/carton width.
7. Cardboard paper boxes, cardboard bonding strength. As with corrugated paper boxes, the force is required to separate the unit length of cardboard face paper from the corrugated paper. Unit: N / m flute.
8. Stacking strength and compressive strength.
The required compressive strength of a cardboard paper box = [gross weight of the box * (stacking layers - 1)] * safety factor K. The former part is the static stacking strength of the cardboard paper box.
Cardboard paper box structure design is from the actual conditions of packaging and production, based on scientific principles of the packaging shape structure and internal accessories for the design. Design must ensure that the structure has sufficient strength, hardness, and the ability to resist other environments.
Qualified cardboard paper box products start with the right structural design. Designers must not only truly understand the customer's intent, but also be familiar with the post-processing process. Designers should understand the nature, shape, size, and weight of the cardboard paper box contents, the arrangement, transportation, and stacking of the contents, the storage environment of the contents, the transportation route and time, as well as the carton box type and production materials before the design begins. Designers in determining the size of the cardboard paper box are mainly to consider two factors: one is to be able to accommodate the contents; the second is to have sufficient strength. Just like the extensions box, it's internal how can contain enough items on how to design. The constraints of the cardboard paper box size and shape of the factors in addition to the contents of the package, there are many other factors, such as ergonomic factors, the size of the pallet, the size of the truck car, the size of the container space, with the size of the shelf size. Only when the design is carried out so meticulously will it be possible to have holographic paper boxes in the future.
Nanjing Lipack Co., Ltd. will provide comprehensive, full, and precise services for target customers is the customer to get greater value-added and create a win-win situation with customers. At the same time, we need to keep innovating, keep pace with advanced technology, and manufacture new concepts of cardboard paper boxes to serve society.
A corrugated carton is made of corrugated cardboard, which is a multi-layer bonded body, it is less by a layer of wavy core paper sandwich and a layer of cardboard, is a kind of cardboard paper box. It has high mechanical strength and can withstand collisions and drops during handling. The next section will introduce you to the advantages of corrugated paper boxes and how to prevent insects daily?

What are the points of corrugated paper boxes?
How can corrugated paper boxes be protected against insects?
Corrugated paper boxes are made of corrugated cardboard and are widely used paper container packaging, which is widely used for transportation packaging. Corrugated packaging paper boxes are widely used because they have many unique advantages.
1. Good cushioning performance. A Corrugated paper box has a special structure. 60-70% of the volume of the cardboard structure is empty, so it has good shock absorption performance and can avoid collision and impact of the packaged goods.
2. Lightweight and solid. A corrugated board is a hollow structure, with less material to form a rigid corrugated paper box body, so it is light and strong, compared with the same volume of wooden boxes, only 1/4 to 1/5 of the weight of wooden boxes.
3. Small size. A corrugated paper box can be folded into a flat board when it is stored and transported, which is convenient for storage and transportation; when it is used, it is opened into a box, and the volume is much smaller than the same volume of a wooden box and plywood box.
4. Sufficient raw materials and low cost. The production of corrugated cardboard raw materials, corner wood, bamboo, straw, reeds, etc. can be, so the cost of corrugated boxes is low, only about half of the same volume of wooden boxes.
5. It is easy to automate production. Complete sets of automatic corrugated paper boxes production lines have been manufactured, which can produce corrugated paper boxes in large quantities and with high efficiency.
6. Low cost of packaging operations. The use of corrugated paper boxes for packaging makes it easy to automate the packaging of goods, reducing the packaging workload and lowering packaging costs.
7. Less metal usage. The corrugated paper box forming, only a small number of box nails, compared with the manufacture of wooden boxes, only and it is only 5%, but still as a rigid paper box.
8. Good printing performance. Corrugated paper box has good ink absorption ability, is easy to print, and convenient to promote goods.
9. Recyclable and reusable. Corrugated paper boxes can be reused many times, reducing the cost of packaging and no pollution to the environment.
1. Physical method.
Pack individual food products with a higher strength film so that insects cannot penetrate the corrugated paper box and prevent insects. But this method must change the existing packaging line, in addition to the extra cost of film.
2. Using chemical methods.
The specific approach is to use paperboard coated with chemicals to package food to prevent insects. The specific approach is to coat the surface of the corrugated paper boxes hanging surface with insect-proof paint. This is not an insecticide, but a natural essential oil that can be used as a food additive. Its function is not to kill insects, but to repel them and prevent them from the outside. This can be done without changing the existing packaging line and keeping the cost low. Its addition is simple and can be printed onto the surface of corrugated paper boxes with aniline printing machines, making it suitable for small batch production of corrugated paper boxes.
Nanjing Lipack Co., Ltd. has boldly introduced advanced automatic production equipment, strengthened production management, and strict quality control. The company, which has been completely transformed, stands out in the fiercely competitive market with its stable quality, fast delivery, and price advantage of corrugated paper boxes, and is developing steadily.
