What kind of printing method is used for general paper packaging boxes?

Offset printing, that is, lithography, is one of the four major printing, and it is the most commonly used one in the printing industry at present. First, paper products use offset printing, and other printing methods are rarely used.

What is this kind of paper in a shoe box or some clothes packaging? What's the use of this paper?

This kind of paper is called copy paper, but it is generally called household paper in China, which is inferior.

Copy paper has a wide range of uses:

1 Fruit packaging: Copy paper is an important paper in northern fruit packaging materials. It was originally used to package Sydney, so it was named Sydney paper.

Clothing, shoes, leather goods and hardware packaging: In the southern market of China, copy paper is mainly used for the packaging of clothing, shoes, leather goods and other products.

Packaging of porcelain, wine and handicrafts: it has the functions of moisture-proof, ventilation, protection and shaping.

4. Copying paper printing: Copying paper has good printing effect, and can be printed in single color, double color, four color, corporate Logo and trademark, and can be dyed red, blue, gold, silver and other colors.

Used for lettering in seal cutting: Because of the special nature and thinness of copying paper, ink does not spread, so when lettering, Yin Gao is often written on copying paper.

So I think it should be used for moistureproof and ventilation.

What are the advantages of paper packaging boxes?

Advantages: the package is cheap, the materials are easy to obtain, it has certain impact buffering capacity, it can be recycled and degraded, and it is convenient to print.

The paper is fully used, and the recycled miscellaneous paper has a certain environmental protection effect, but the paper mill itself is seriously polluted by acid and alkali.

What paper does the packaging industry generally use to make gift boxes (chip cardboard boxes)? 5 points

Hardcover boxes generally use coated paper or matt paper. Corrugated color boxes generally use gray board paper (white characters on gray background)

What kind of paper is used in general paper bags? What is the size?

CorelDraw 10 (or 1 1, 12) is generally used to make portable paper bags. This is a vector graphics production software, which can be enlarged without distortion. Now the packaging design can also use his. PS, but the effect is not as good as CorelDraw. The packaging box designed by our company now uses CorelDraw. Download Huajun Software Park onlinedown/ Zhongguancun online download channel download.zol/ Portable Application Alliance xdowns/ portable paper bag size design must be disassembled, and the size of six sides should be quite accurate. The specific size depends on the customer's requirements.

What paper do you usually use for food wrapping paper?

White board and gray board are commonly used in packaging, but the prices are different, and the white board is more expensive.

The general packaging paper is 250g gray board, but different factories have different requirements, mainly using gray board.

In addition, copy paper, decal paper, dust-free paper, etc. are usually used.

How to distinguish the materials of packaging cartons?

What's the name of the material used in the paper packing box?

Materials of paper packaging box: corrugated board and honeycomb board.

Characteristics of corrugated board

Corrugated board is a widely used board, which uses paper instead of wood, especially for commodity packaging. According to the shape of corrugated, it can be divided into U-shaped, V-shaped and uv-shaped corrugated.

According to the cross-sectional structure of corrugated layer, it can be divided into five kinds of corrugated boards: A, B, C, D and E. According to the number of corrugated layers, it can also be divided into one, two, three, five and seven layers of cardboard (that is, three-layer corrugated board). The main features of corrugated board are:

(1) Corrugated boxes made of corrugated cardboard are usually transported in the form of folding or tiling, which is convenient to carry, improves transportation efficiency and saves storage space.

(2) The corrugated cardboard packaging box has low manufacturing cost and saves materials.

(3) High strength and good cushioning performance, which can avoid the collision and impact of packaged goods, and is especially suitable for the transportation and packaging of heavy products such as machinery and electromechanical products. (4) The production of corrugated boxes can be carried out on highly mechanized, automated and efficient equipment with high working efficiency.

Characteristics of honeycomb paperboard

Honeycomb paperboard is made according to the principle of natural honeycomb structure. It is a new type of environment-friendly and energy-saving material, which has a sandwich structure. Corrugated base paper is connected into countless hollow solid regular hexagons by adhesive bonding, forming an integral stress part-paper core, and both sides are bonded with facial paper. The main features of honeycomb paperboard are:

(1) has the advantages of light weight, less materials and low cost. Compared with other kinds of board structure, honeycomb sandwich structure has the largest strength/mass ratio, so its finished product has better cost performance, which is the key to the success of honeycomb paperboard.

(2) High strength, smooth surface and difficult deformation. Honeycomb sandwich structure is nearly isotropic, with good structural stability and not easy to deform. Its outstanding compression and bending properties are the most important characteristics required by box packaging materials.

(3) Good impact resistance and cushioning. Honeycomb paperboard is made of flexible paper core and tissue paper, which has good toughness and resilience. The unique honeycomb sandwich structure provides excellent cushioning performance, and the energy absorption per unit volume is higher among all cushioning materials. High-thickness honeycomb paperboard can replace EPS foam plastic liner which is widely used at present.

(4) Sound absorption and heat insulation. The interior of honeycomb sandwich structure is a closed cell filled with air, so it has good sound insulation and heat preservation performance.

(5) No pollution, in line with the trend of modern environmental protection. Honeycomb cardboard is all made of recyclable paper, which can be 100% recycled after use.

Scraps and scraps in the production process of corrugated boxes can also be die-cut and bonded to make various shapes of honeycomb corrugated board cushions. Even if discarded, it can be naturally degraded and absorbed, and it is a good green packaging material. In Europe and America, the wooden packaging of goods imported from China must be fumigated, and honeycomb paperboard, as a new type of environmental protection material, can fully meet the packaging requirements of goods imported from China in Europe and America.
