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.

Here is the table of contents.

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.

Advantages of window paper bags

From a design point of view, the Window paper bag is not limited to a certain area or a certain pattern. If used properly, it will produce some unexpected effects, which will help increase consumer goodwill and consumer desire. From a production point of view, opening a window is also a cost-saving method. We all know that window packaging bags are also to be printed. However, compared with full-page printing, the larger the window, the more printing ink can be saved. From a practical point of view, the Window paper bag can more intuitively display the product itself and increase the selling point. Consumers can see what kind of products they want at a glance, saving some tedious steps and indirectly eliminating consumers’ worries about products.

What are the types of flower paper bags?

According to the different ways of bag side, bottom and back cover, it can be divided into open seamed bottom bag, open adhesive corner bottom Paper bag forms such as bag, valve suture bag, Window paper bag, etc. According to the different handles and digging methods: NKK (perforated and threaded), NAK (non-holes and cords, divided into no-fold and standard fold-type), DCK (cordless bag body digging handle), BBK (with The tongue is not punched).

What are the advantages of using window paper bags to pack flowers?

Using Paper bags for flowers packaging is safer and more environmentally friendly. The paper bag is non-toxic, tasteless, and non-polluting. It meets the standards of the National Environmental Protection Agency, has high strength, and is highly environmentally friendly. It is currently one of the most popular environmentally friendly packaging materials in the world. The resistance to cracking, destruction, and dynamic strength are very high. The window design is very delicate, allowing people to see the beautiful flowers inside while protecting the flowers from accidental damage from the outside world. The bottom is widened and thickened, and the volume becomes larger. It can be placed in a standing position: The thickened bottom design makes the product packaging bag more load-bearing, and the bottom is not easy to fall, so it is firmer and safer. What’s more, the Paper bag for flowers has a retro feel, toughness, and is not easy to deform.

In today's society, people's awareness of environmental protection continues to increase, and they also prefer products with environmental protection words. Many companies are paying more and more attention to shouldering their social responsibilities, and they are all making contributions to environmental protection in their way. Our company is no exception, we are committed to providing a more environmentally friendly paper bag for the retail store. In this article, we will introduce the environmental protection of paper bags for retail stores.

Environmentally friendly paper materials

Recycled paper is the main material for the retail paper bag produced by our company. Rather than cutting down trees to reduce vegetation coverage, we are more inclined to choose recycled paper made from recycled paper to make retail paper bags. In this way, we can not only reduce the production cost of retail paper bags, thereby reducing the sales price of retail paper bags to benefit customers but also avoid the problem of aggravating vegetation damage, thus better protecting the ecosystem. As the old saying goes-kill two birds with one stone.

The above is the environmental protection reflected in the retail paper bag production process. Next, let's talk about the part reflected in the use process. Because it is a paper bag, the service life will not be as long as that of a woven bag or plastic bag. But please don't worry, our paper bag for the retail store is 100% recyclable. Even if it does not flow into the recycling channel, it can be completely degraded. So please rest assured to use our retail paper bag.

Environmentally friendly printing ink

Due to the need for aesthetics or publicity, some patterns or text are sometimes printed on our paper bag for a retail store. At this time, you may be worried. Will the ink attached to the paper bag for retail stores pollute the environment? We have also considered this issue, so we use environmentally friendly water-based soy ink for printing. This ink is extracted from soybean oil, which is renewable, non-hazardous, and easy to recycle. In addition, its resistance to light, heat, and friction is also stronger than traditional inks. Soy ink has high transparency, good fluidity, and colorability, bright colors, and is not easy to fade. It is suitable for a wide range of color printing. When paper bags for retail stores are recycled, soy inks are easier to clean during the deinking process than traditional inks, which effectively reduces the damage to the retail paper bag during deinking. It also makes the deinked retail paper bag easier to degrade.

In contemporary times, protecting the ecological environment and developing a green economy has gradually become the general trend. From various government policies on restricting the use of plastics, we can see that the government attaches great importance to environmental protection.
