A corrugated paper box is die-cut, creased, nailed, or glued to make corrugated boxes. Corrugated paper box is one of the most widely used cardboard paper boxes, and the amount has been the top of various packaging products. Next, we will introduce you to corrugated paper boxes.

What is the technology and principle of the corrugated paper box?

1. The main printing methods in the corrugated paper box industry are.

Lithographic offset printing (ink color printing), letterpress printing (carton water-based printing). Compared with color printing, water-based printing has high strength, low cost, high production efficiency (fast delivery time), and an overall printing effect close to color printing, which is widely used in the transportation packaging of products.

2. Main production processes of a corrugated paper box.

Corrugated paper box automatic production line, printing process, post-processing, and forming process; printing work has realized the automatic operation of printing, slotting, die-cutting, gluing and packaging in one process.

3. Water-based printing of corrugated paper boxes belongs to the additive color printing method. The color original is electronically color-separated into a reverse image and then printed on a printing press. The ink is transferred from the anilox rollers of the printing press to the printing plate, and then the ink is transferred from the printing plate to the corrugated board. Most of the cartoon paper boxes are also printed using the overlay color method.

4. Prepress technology (traditional plate making)

(1) Color originals processed by electronic color separation into monochrome and then out of the film sheet (negative image soft film).

(2) Back exposure: exposure of the back of the plate with ultraviolet light to form the base of the printing plate.

(3) The main exposure: remove the protective film on the front of the plate, put on the negative picture, cover the vacuum film, vacuum pumping, the main exposure with ultraviolet light, the content of the negative picture transferred to the printing plate.

(4) Wash plate: wash the plate in the plate washer with a potion to wash off the unexposed resin on the printing plate, forming the intaglio printing plate.

(5) Drying.

(6) De-stick: ultraviolet light source irradiation.

(7) Post-exposure: hardness adjustment.

What kinds of shapes are there in corrugated boxes?

According to the shape of corrugated, there are 3 designs of corrugated paper boxes: V, U, and UV.

The V-shaped corrugated waveform is characterized by a high value of plane resistance pressure, which saves adhesive usage in use and saves corrugated base paper. However, corrugated paper boxes made of this waveform are poorly cushioned and do not easily recover from pressure or impact.

The U-shaped corrugated waveform is characterized by a large adhesive area, strong bonding, and a certain degree of elasticity (better recovery). When a corrugated paper box is impacted by external forces, it is not as fragile as a V-shaped flute, but the plane is not as strong as a V-shaped flute.

Based on the performance characteristics of V-flutes and U-flutes, UV-shaped corrugated sticks, which combine the advantages of both, are now commonly used. The result is a corrugated packaging paper box that maintains the high-stress resistance of V-flute and the high adhesive strength and flexibility of U-flute.

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.

What are the points of corrugated paper boxes?

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.

How can corrugated paper boxes be protected against insects?

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.
