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?
What kinds of shapes are there in corrugated boxes?
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.
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.
Nanjing Lipack Co., Ltd. attaches great importance to customer experience, the pursuit of cost-effective products, to provide more valuable and more impressive corrugated paper boxes, to better enhance customer brand recognition and product sales!
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.
Based on the principle of trying our best to meet customer needs, our company can provide customers with customized retail paper bags. Customers can put forward requirements for the design of retail paper bags according to their preferences and actual user needs. Not only the paper quality used in the retail paper bag can be changed according to customer requirements, but also the handle of the retail paper bag can also be changed. This article will briefly introduce the different types of handles.
Here is the content list:
l Paper handle
l Plastic handle
l Braided handle
The retail paper bag handle shape of this material is more diverse. Let's start with the twisted paper handle. Twisted paper handles are usually made by twisting the kraft paper into a long strip, then cutting it to an appropriate length, and finally sticking its ends on the inside of the retail paper bag. This form of paper retail paper bag handle is relatively tough and not easy to pull off. There is also a flat paper handle. Unlike the twisted paper handle, the cross-section of this handle is flat and different from the round cross-section of the twisted paper handle. This kind of retail paper bag handle has a larger contact area with the user's hand, which means that the force area is larger. Under the same pressure, the pressure received by the retail paper bag user's hand is smaller. The last is the die-cut handle. This design is very material-saving. The process of making it is also very simple, that is, to open an oval hole on the finished retail paper bag, the size is suitable for the average person to penetrate three to four fingers.
The appearance of the retail paper bag handle described below is very similar to the twisted paper handle mentioned above, but it is made of PP as the main raw material, which is what we often call polypropylene. Plastic handles tend to be stronger and more malleable than fragile paper handles. In addition, it is fixed to the retail paper bag in a perforated manner, which means that it can withstand heavier contents. Generally, wine bags, or retail paper bags for shoes, can consider using this type of handle.
Compared with the retail paper bag handles of the previous two materials, the braided handle is undoubtedly a more friendly handle. We offer two options here, one is a cotton rope, the other is a ribbon handle. The handle made of woven fabric is softer and more comfortable, and it is also more textured, which helps to complement the appearance of the beautifully designed retail paper bag to create a more ideal visual effect. Some luxury stores generally use ribbon handles as the handles of their retail paper bags, because this handle is shiny, feels good, looks more stylish, and is in line with the style of their products.
