Do Kraft paper bags have several practices?
What are the performance parameters of kraft paper bags?
(1) small white kraft paper bags, the general number of such bags, the use of a wide range, many customers require such cheap and durable kraft paper bags, usually the practice of such kraft paper bags are machine forming, machine laminated rope, completely by the machine operation.
(2) the practice of medium-sized kraft paper bags, usually, medium-sized packaging bags are machine laminated molding after the human hand sticker rope and made into kraft paper bags, due to kraft paper bag forming equipment by forming size restrictions, and kraft paper bag sticker rope machine can only stick smaller handbag rope, so the practice of kraft paper bags by the limitations of the machine. Many of the bags do not have the means for the machine to complete the sole production, still have to go through manual production.
(3) large bags, with reverse-head kraft paper bags, thicker yellow kraft paper bags, the practice of these kraft paper bags to be built purely by hand, to ensure quality, these types of kraft paper bags can not yet be put into machine production, these types of kraft paper bags production costs are higher, but also very strong, good quality.
(4) regardless of which kraft paper bags are above, if the number is not large enough, generally used purely handmade, because of the machine production of kraft paper bags loss, there is no way to solve the practice of small quantities of medium-sized packaging bags.
(1) Printing: Offset printing, CMYK printing, screen printing
(2) Handle material: twist paper handle bag
(3) Surface treatment: silver print, gold print, embossed or embossed, spot UV, varnish, matt laminate, gold laminate
(4) Size: custom made
(5) Shapes: flat pockets, square bottom open pockets, square bottom valve pockets, one-piece glued bottom bags (for food packaging)
(6) Material: polypropylene, kraft paper, aluminum foil
(7) Stitching method: paper sealed bottom, heat-sealed bottom, glued bottom.

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!
Generally, brands spend a lot of time and effort to perfect every detail of their products before they are launched. All the marketing messages that the brand presents to the public are kept in mind by the customers. Therefore, in addition to the product itself, jewelry paper bags are also one of the important factors that need to be considered as a priority. Also, jewelry paper bags can be considered as an extension of your brand.
Here is the content list:
l Product advantages from quality jewelry paper bags
l What kind of jewelry paper bag should be selected for the product?
1. Quality jewelry bags help to display jewelry or precious items in an attractive way.
2. Quality jewelry paper bags help keep items safe.

5. High-grade jewelry paper bags add value to jewelry or products and also add a certain charm.
If you want to make your luxury jewelry paper bags shine in the sales process and use them as an extension of your brand, you need to consider the following points.
1. Brand style: is it fashionable, retro, high-end, fun? Which paper bag color to use will have a big impact on the customer's buying decision. The most important thing is that you need to make sure that the style of the jewelry paper bag matches the style of your entire brand.
2. Attract the target user: For example, if your target user is the post-90s, you may make the appearance of jewelry paper bags more modern will be more attractive to their attention. On the other hand, if your users are middle-aged successful people, then there is no need for too many popular design elements when customizing jewelry paper bags.
3. Can fight against competitors: The purpose of custom jewelry paper bags for brands is to protect the product and stand out from the many competitors.

Only distinguish from the competition can also ensure that the product stands out.
