Most of the paper packaging we come into contact with is industrial white cardboard, also known as FBB (FOLDING BOX BOARD), which is a single-layer or multi-layer combined paper that is wholly made of bleached chemical pulp and full-sized. It is suitable for the Printing and packaging of products characterized by high smoothness, good stiffness, clean appearance, and good formation. C1S Ivory board has very high requirements for whiteness. There is A, B, and C three grades according to the different whiteness. The whiteness of grade A is not less than 92%, the whiteness of grade B is not less than 87%, and the whiteness of grade C is not less than 82%.

Due to different paper mills and different usages, FBB is divided into many brands, and ivory board at different prices also correspond to other final products.

The common packaging on the market is basically made of industrial FBB. Among them, the NINGBO FOLD (FIV) produced by the APP paper mill ( NINGBO ASIA PULP & PAPER CO., LTD ) is the most famous brand, and the others are the IBS, IBC of the BOHUI paper mill. (Now BOHUI PAPER MILL also belongs to the APP group, getting better managed and more stable production every month )

The regular GSM of NINGBO FOLD (FIV) is 230gsm, 250gsm, 270gsm, 300gsm, 350gsm, 400gsm.(same price for range 230-400 GSM )

Due to the difference in bulk, FBB can be divided into normal bulk FBB and high bulk FBB. Due to the thickness requirements of packaging cardboard in different regions, the bulk difference mainly depends on the difference of the market. The bulk of normal bulk FBB is generally around 1.28. The bulk of high-bulk FBB such as IBM, IBH, and IBM-P is basically around 1.6. High-bulk FBB has two advantages over normal bulk FBB: one is the high whiteness of the finished paper, and the product grade is high; the other is the high bulk, which has cost advantages for users.



Due to the whiteness requirements of industrial FBB, fluorescent whitening agents are added, but this additive is harmful to the human body, so the food-grade board is not allowed to add fluorescent whitening agents. The card is the same as industrial FBB, but it has higher requirements on the workshop environment and the composition of the paper, and cannot contain substances that are harmful to the human body.

Since it does not contain fluorescent whitening agents, the food-grade board is basically yellowish in color and is mainly used in food-related packaging or high-end cosmetic maternal and child products.

Food-grade board can be divided into the ordinary food-grade board which can be used for frozen products.

The duple board is also a very widely used paper in the packaging industry. In addition to the ivory board, common packaging materials also includes duplex board. Duplex board is a kind of uniform fiber structure, with filler and sizing components on the surface layer and a layer of paint on the surface, which is produced by multi-roller calendering. This kind of paper has high color purity, relatively uniform ink absorption, and good folding resistance, and the duplex board has small flexibility, and toughness, and is not easy to break when folded. It is mainly used for printing packaging boxes. Duplex board can be divided into white back duplex board and grey back duplex board.

The duplex with a white back is double-sided white, the regular gsm is 250/300/350/400/450gsm.

The duplex with a grey back is one side white and one side grey, it is normally cheaper than a double-sided white duplex, and the regular gsm varies from different brands.

Coated paper and coated board are often used in printing, so what is the difference between coated paper and coated board? Generally speaking, coated paper is lighter and thinner. In terms of usage, the two are also different.

Coated paper, also known as coated printing paper, is called powdered paper in Hong Kong and other regions. It is a high-grade printing paper made of base paper coated with white paint. It is mainly used for printing the covers and illustrations of high-end books and periodicals, color pictures, various exquisite commodity advertisements, samples, commodity packaging, trademarks, etc. 

The characteristic of coated paper is that the paper surface is high in smoothness and has good gloss. Because the whiteness of the paint used is more than 90%, the particles are extremely fine, and it has been calendered by a super calender, the smoothness of the coated paper is generally 600~1000s.

At the same time, the paint is evenly distributed on the paper and shows a pleasing white color. The requirement for coated paper is that the coating is thin and uniform, without air bubbles, and the amount of adhesive in the coating is appropriate to prevent the paper from powdering and hair loss during the printing process.

The following is the detailed difference between coated paper and coated card:

Characteristics of coated paper:

1. Forming method: one time forming

2. Material: high quality raw material

3. Thickness: general

4. Paper surface: delicate

5. Dimensional stability: good

6. Strength/Stiffness: Normal, Internal Bonding: Good

7. Main application: picture book

The regular gsm of art paper: 80gsm, 90gsm, 100gsm, 128gsm, 158gsm, 200gsm, 250gsm, 300gsm.( It means for gsm from 80-300 gsm art paper can be in glossy or matte )






Characteristics of coated board:

1. Forming method: one-time molding and multiple molding together, generally three layers

2. Material: cheap fiber can be used in the middle

3. Thickness: Thick

4. Paper surface: slightly rough

5. Dimensional stability: slightly worse

6. Strength/Stiffness: Strong, Internal Bonding: slightly worse

7. Main application: package

The regular gsm of C2S art board: 210gsm, 230gsm, 250gsm, 260gsm , 280gsm, 300gsm, 310gsm, 350gsm, 360gsm, 400gsm. ( Art board over 300 gsm can only in gloss, no matte )



Offset paper, formerly known as "Daolin paper" and wood-free paper is mainly used for lithographic (offset) printing presses or other printing presses to print higher-level color prints, suitable for printing single-color or multi-color book covers, texts, inserts, pictorials, maps, posters, color trademarks, and various packaging paper.

Offset paper is generally made of bleached coniferous wood chemical pulp and an appropriate amount of bamboo pulp. 

When processing offset paper, filling and sizing are heavy, and some high-grade offset papers also need surface sizing and calendering. Offset paper uses the principle of water-ink balance when printing, so the paper needs to have good water resistance, dimensional stability and strength. Offset paper has the advantages of white quality, crispness, flatness and fineness. After the books and periodicals are made, the characters are clear, and the books and periodicals are flat and not easy to deform.

Offset paper can be classified according to color: super white, natural white, cream, yellow.


The regular gsm of offset paper: 68gsm, 78gsm, 98gsm, 118gsm. 



Carbonless copy paper is a kind of leuco copy paper, which has the functions of direct copying and direct color development. Its color development is mainly: under the action of external force, the force-sensitive pigment and oil solution in the microcapsules overflow and contact with the color developer to cause a dyeing reaction, thereby playing the role of copying. It is mainly used for multiple forms, bills, continuous financial notes, general business financial notes, etc.

There are two coatings in carbonless copy paper: a CF layer containing a chromogenic agent and a CB layer containing a chromogenic agent. The chromogenic agent is a special colorless dye that has been dissolved in non-volatile carrier oil and encapsulated by microcapsules of 3-7 μm. The impact pressure of forceful writing and printing can crush the microcapsules, allowing the colorless dye solution to flow out and contact the color developer, and a chemical reaction occurs to present colored graphics, thereby achieving the purpose of copying. Carbonless copy paper is divided into 45g/m2CB paper, 47g/m2CF paper and 52g/m2CFB paper according to the quantity; according to the color of the paper, there are five types: red, yellow, green, blue, and white; according to the color traces, there are blue, Yellow, orange, black, red and other colors.


Carbonless copy paper is mostly used on documents. The existing formal documents with legal effect such as invoices, contracts and treaties have all used carbonless copy paper. Traditional receipts are just ordinary paper, so it is necessary to add a carbon layer under the receipt. The carbonless copy paper is bound with special paper.



As far as triplet carbonless copy paper receipts are concerned, they can be divided into upper paper, middle paper, and lower paper. Upper paper is also called back-coated paper (code name CB, that is, Coated Back), the back of the paper is coated with microcapsules containing Limin pigment oil; middle paper is also called front and back double coated paper (code name CFB, that is, Coated Front and Back), The front side of the paper is coated with the color developer, and the back is coated with microcapsules containing Limin pigment oil; the lower paper is also called surface-coated paper (code name CF, that is, Coated Front), and the paper surface is only coated with the color developer. Self-coloring paper (codenamed SC, Self-Contained) is coated with a microcapsule layer containing Limin pigment oil on the back of the paper, and coated with a color developer and microcapsules containing Limin pigment oil on the front.

The upper paper and the lower paper do not have the copying effect, only the middle paper has the copying effect. When using documents printed on carbonless paper, there is generally a small piece of cardboard placed on the form, so as to avoid excessive writing force and cause other forms placed below to be copied.
