A. Classification of cardboard materials Cardboard materials are classified according to the weight per unit area. In the mainland market there are mainly the following kinds of paperboard K paper: 250g/M*M A paper: 175g/M*M B paper: 125g/M*M (these three generally imported paper) 7 paper: 200g/M*M 8 paper: 260g/M*M C paper: 127g/M*M (Taiwan paper) core paper: basic 100g/M*M large machine 105-110g/M*M strengthened core paper: + paper 115g / M * M other reinforcing core depending on the customer, in Taiwan there are 130g, 140g, 150g, 180g, 190g / M * M reinforcing core paper, but in mainland China is common 140g, 150g, 180g / M * M reinforcing core paper. II. Cardboard structure 1, cardboard structure refers to the number of cardboard ratio combinations, generally according to customer requirements to do the ratio, from the five-layer K Ⅲ K, K Ⅲ A to three-layer C Ⅱ can be. 2, the pit (wave) refers to the holes in the cross-section of the cardboard. Commonly, there are A wave, B wave, C wave, D wave, E wave. The mainland generally use B wave, C wave, E wave. 3, wave height: A wave = 5mm B wave = 3mm C wave = 4mm D wave = 2mm E wave = 1.5mm, five-ply paper two waves consisting of BC pits, single-ply paper is generally used in the B pit. Three. Carton form Carton is generally divided into A-type, B-type, C-type, packaging cartons and beer boxes, knife card, partition. 1, A type: common A1: general standard type; A3: bottom without cover or cover without bottom type; A5: double cover completely interspersed. 2, the partition refers to the carton in the upper, middle, lower, left and right objects are separated from each other to play a protective role of cardboard. Knife card refers to the same layer of objects in the honeycomb nest type packaging with a cut and interlocking paper card. 3,C-type is the carton for shoes, which has an open and closed lid. 4, packaging carton: similar to the A5 carton, but generally directly affixed to the tape packaging, not nailed, can be divided into open or side-open type. Carton material introduction, if good. To add points so it seems that K paper seems to be the best paper. Generally use B=B, paper thickness of about 6mm, the lowest material. If customers have requirements, can also be used A = B, this material is better than B = B strength, the price is high, and A = A paper quality than A = B, B = B good, the thickness of 6mm, the price is also high, unless the special requirements of the selection of the first letter (such as K A B) that the outer layer of paper quality, the middle symbols (such as =) that the number of layers, the latter letter that the inner layer of paper quality W-white outer box A-good yellow box B-slightly poorer yellow paper K-quality of paper Best and most expensive W=A five-layer good paper white box W=B five-layer slightly poor paper white box W=A=B five-layer good white box (this is universal) A=B five-layer yellow box (this is universal) 3A=B three-layer yellow box (medium) 3B three-layer yellow box (poor) for dolls A=B five-layer yellow A=A five-layer yellow W=A five-layer white W=A five-layer white W=B five-layer white A3A three-layer yellow W3A three-layer white box W3K three-layer white outer box 3A three-layer yellow outer box (good) Facing paper: W represents 160 grams of white kraft card; K represents 230 grams of kraft card; A represents 175 grams of kraft card; B represents 127 grams of kraft card; C represents 127 grams of kraft hanging (imitation kraft card); I hope that the above can help you. Thank you for adopting!

For a long time, corrugated cartons have been widely used as the main form of single transportation packaging, which also determines its printing process to stay in the stage of simple line-text printing, which has been unable to get faster development.
However, with the continuous development of the packaging market, the single transportation function of the carton has gradually changed to a sales function, and consumers' purchasing psychology and aesthetic concepts have also been changing; the continuous growth of export commodities has also forced the domestic carton production to internationalization, which has resulted in higher and higher post-pressing requirements on the one hand, and higher requirements for the environmental performance of the products on the other. Wallem carton is responsible for the double task of commodity transportation, commodity display and promotion.
Its color is becoming more and more bright and eye-catching, and the pattern printing is becoming more and more exquisite, so that it can attract customers' interest and *** purchase desire. This requires corrugated cartons to meet the strength of the same time to have excellent surface printing quality, multi-color color printing has gradually become the future direction of the development of carton printing.
Introduction to the carton printing process At present, China's corrugated carton printing methods are varied, mainly offset printing, flexo direct printing, flexo or gravure pre-printing, screen printing, as well as in recent years has just risen in the digital printing methods. Among them, corrugated carton ink flexo printing occupies the main market of carton printing with its advantages in plate material, ink, printing pressure, printing efficiency and other aspects.
Each printing method has its own advantages and disadvantages and the scope of printing, according to the actual situation and the characteristics of the carton products to choose the appropriate printing process. Carton offset printing process Offset printing has a simple plate making process, low cost, fast speed advantage, is the most widely used indirect printing technology, in the printing of books, newspapers and magazines, paper packaging printing has always occupied a dominant position.
The graphic portion of the printing plate and the blank portion of the printing plate are almost on the same plane. When printing, water is first supplied to the printing plate to wet the blank portion of the printing plate, and then the ink is coated, and the principle of oil and water repulsion is applied to transfer the ink to the rubber blanket and then to the substrate to complete the printing process. Offset corrugated box printing is divided into offset indirect printing and direct printing two ways.
The indirect printing method is to print the corrugated box face paper first, and then use a single machine to re-laminate the corrugated. Offset printing products can be screened up to 200 lines / inch, beautiful patterns, stable quality and high quality.
The PS version of the plate is easy to make, but also can be laminated, varnished and other surface finishing processes, in the current high-grade sales of packaging carton printing accounted for a considerable part of the proportion. Offset printing technology, although more mature, fast printing speed, but the way is not suitable for cardboard linkage production line, finished product production efficiency is low, complex processes, long cycle.
As the offset printing process to the fountain solution, will increase the moisture content of the original paper, improper control is also prone to overprinting failure. Coupled with offset printing pressure, printing width is limited and other factors, can not meet the needs of high-volume carton production.
From the point of view of the cardboard processing technology, offset printing after the process of lamination, but also due to the pressure and the colloid left too much moisture, so that the carton of the flat compression strength, adhesive strength and other technical indicators are difficult to meet the requirements of high-grade goods on the packaging. In addition, offset printing is currently no relatively environmentally friendly ink use is also affecting the use of its promotion of another obstacle.
The development and use of micro-corrugated products is the future development trend of the carton industry, and offset printing is the best way to print and process them. The direct offset printing process for corrugated cartons is now more mature in foreign countries, and the production of corrugated cardboard can be put directly into a special offset printing machine.

Carton materials and specifications:
Carton commonly used three-layer, five-layer, seven-layer use less, each layer is divided into lining paper, corrugated paper, core paper, facial paper, lining, facial paper, tea board paper, kraft paper, corrugated paper core paper, a variety of paper color and feel are not the same, the paper produced by different manufacturers (color, feel) is not the same, the national standard for corrugated cardboard boxes GB6543 The national standard for corrugated cardboard boxes is GB6543-86 "corrugated cardboard boxes".
Carton class:
At present, the commonly used types of cartons are: double-tower carton, A work carton, heaven and earth cover carton; commonly used sealing method: I-word, Wang-word, day-word; the thickness can be divided into: three-layer, five-layer, seven-layer;
a. Ordinary carton paper: Ordinary carton paper X: K A B C 3 in order of deterioration; X9X (thickness of 2 mm) that E Pit (young pit) X3X (thickness of 3 mm) - indicates a single layer X = X (thickness of 6 mm) ---- indicates a double layer X ≡ X (thickness of 9 mm) ---- indicates a triple layer X ---- indicates the surface paper, pit pattern ---- ordinary pit paper, the intermediate layer of flat paper ---- does not indicate that, then the ordinary paper. W-indicates white paper, single pit (paper) double pit (paper) three pit (paper) young pit (paper).
b. Ordinary carton material selection:
General use B = B, paper thickness of about 6mm, the lowest material. If the guests have requirements, can also be used A = B, this material is better than B = B strength, the price is high, and A = A paper quality than A = B, B = B good, the thickness of 6mm, the price is also high, unless the special requirements to choose.
Cartons now use corrugated class shape generally have A flute, C flute, B flute, E flute; four, their height for the A & gt; C & gt; B & gt; E; to do the inner box are generally used E flute flat and beautiful, the outer box is generally used BC flute thickness is moderate, compression resistance is not bad, if you ask for the box compression resistance is good, then you can choose the AB flute. Now the domestic use of paper stamps have nine dragon paper, not bad, the quality of the quality of imported paper is not far away, but the price is relatively cheaper.

Beer box, beer card depends on the processing costs depending on the style of the 4. centimeters converted to inches formula: inches = centimeters * 2.54 5. K paper is the best paper. W paper is white paper. 6. I believe that you have an understanding of this, so here to say more. In addition to add a little. I do not want to type. COPY from the outside, we look at: the structure of the carton expression is as follows: top paper: paper name, weight / tile: tile strength, weight, flute / core paper: tile strength, weight / liner: paper name, weight example: top paper kraft card 300 grams / high tile 180 grams (A/B flute) / core paper 180 grams of Puwa / liner 280 grams of containerboard corrugated carton pricing formula Carton price ($) = Corrugated cardboard factory price per square meter (yuan / m2) * carton unfolding area (m2) a. Calculation of corrugated cardboard factory price per square meter 1.
The three-layer corrugated box is mainly used for packaging lightweight inner packages, three-layer corrugated box is also called a single corrugated box its structure is made of a corrugated paper on both sides of the sticky one face paper combination. Five-layer corrugated boxes are mainly used for single-piece packaging of lighter weight and fragile contents; five-layer corrugated boxes, also known as double-corrugated boxes, used to be referred to as three yellow two-watt.
The structure of the five-layer corrugated box is made of face paper, liner, two core papers and two sheets of corrugated paper bonded together, and the combination of flute type usually adopts the AB type (the pharmaceutical packaging in Chongqing area with this type of the most), the AC type, the BC type, the AE type or BE type. Seven-layer corrugated carton consists of the following cardboard three-layer corrugated boxboard (mainly used for heavy-duty goods packaging, such as motorcycles, etc.); Composition: from the face of the paper, corrugated paper, corrugated paper, core paper, corrugated paper, corrugated paper, corrugated paper, corrugated paper, liner glued together and become.
The combination of corrugated flute type is usually BAB type, BAA type, CAC type or BAC type 2. Unified corrugated cardboard unit of measurement 1). General carton factory purchases face paper, liner, core paper, corrugated medium are calculated by tons. That is, the various kinds of paper, liner, core paper, corrugated medium for how many yuan per ton, the unit is expressed as "yuan / ton", and the calculation must be converted into "yuan / kg", such as the purchase price of 5200 yuan / ton, then by kilogram that is 5200 yuan / 1000kg = 5.20 yuan /kg. 5.20 yuan / kg.2). The general weight of paper usually speak grams, in fact, should be how many grams per square meter that is, a variety of paper, paper, core paper, corrugated paper weight are "g / m2" as the representative unit for the calculation of the amount of units must be unified here must be "g / m2" Converted to "kg/m2".
If the purchase of 300 grams of kraft paper, that is, 300g/m2 of kraft paper, at this time will be "300 grams / m2" converted to (300/1000) kg / m2 "will be 0.3kg / m2. 3). Corrugated cardboard to produce corrugated coefficient of determination of corrugated cardboard due to pressure corrugated caused by the shortening of the length of the paper in the direction of the shortening ratio known as the compression ratio coefficient.
This coefficient is not standardized among manufacturers because the production capacity and management level of each manufacturer directly affects the yield of corrugated board, but the packaging industry generally defaults to the following coefficients: A flute compression ratio coefficient of 1.59, which means that 1.59 meters of corrugated board is 1 meter long after corrugating; B flute compression ratio coefficient of 1.36, which means that 1.36 meters of corrugated board is 1 meter long after corrugating. The compression ratio coefficient of B flute is 1.36, i.e. 1.36 meters of corrugated paper is 1 meter long after corrugation.
The compression ratio coefficient of C flute is 1.50, i.e., 1.50 meters of corrugated paper is 1 meter long after corrugating, and the compression ratio coefficient of E flute is 1.27, i.e., 1.27 meters of corrugated paper is 1 meter long after corrugating.
3. Corrugated boxes of various paper per square meter of paper price calculation (1) (1) face paper, lining paper, core paper algorithm Example: the purchase price of 4,800 yuan / ton of face paper for 350 grams / m2, the price per square should be; (4,800/1,000) * (350/1,000) = 4.8 * 0.35 = 1.68 (yuan / square meter) (2) (2) Corrugated paper algorithm Example: the purchase price of 1800 yuan / ton of high-strength tiles for 180 g / m2, the price per square meter should be: (1800/1000) * (180/1000) * 1.59 = 1.8 * 0.18 * 1.59 = 0.516 (yuan / square meter) 4. Calculation of the cost per square meter of raw materials for corrugated cardboard Existing customers want to make a five-layer corrugated cardboard box, the requirement to use a top paper for the Kraft Card 300 grams / high tile 180 grams (A/B flute) / grid paper 180 grams Pu / liner 280 grams of tea board paper, try to calculate the cost price per square meter of containerboard. List of calculations: paper name weight price (yuan / ton) ply coefficient calculation formula (yuan / per square meter) kraft 300 5200 1 1 (300/1000) * (5200/1000) * 1 * 1 = 1.56 high-strength tiles 180 2250 2 (1.56 + 1.39) (180/1000) * (2250/1000) * 2 * 2.95 = 2.39 Core paper 180 1700 1 1(180/1000)*(1700/1000)*1*1=0.306 Lining paper tea board paper 280 2500 1 1(280/1000)*(2500/1000)*1*1=0.70 Total (yuan per square meter) = 4.965. Main factors and coefficients for calculating the ex-factory price of corrugated cardboard cartons The ex-factory price should include the cost of raw materials and other amortized costs of cartons.
Other amortized costs include auxiliary materials (adhesives, ink, flat wire, power), depreciation of equipment, workers' wages, taxes, etc. In the ex-factory price of the carton, the cost of raw materials for cartons generally accounts for 0.5-0.7, and other amortized costs account for 0.5-0.3, and the general manufacturer's value is the cost of raw materials for cartons accounted for 0.65, and other amortized costs accounted for 0.35. While the simple projections are based on the factor of half of the materials and half of the labor, i.e., 0.5 for the large both. 0.5 coefficient for the large both estimated.
6. The ex-factory price of corrugated cardboard boxboard ex-factory price = boxboard raw materials per square meter cost price / 0.65 As noted in "4. boxboard raw materials per square meter cost price calculation" in the information provided can be calculated boxboard ex-factory price should be; boxboard ex-factory price = 4.96 / 0.65 = 7.63 yuan / square meter.
Carton material is divided into how many categories of different carton materials have what uses
Carton material is divided into how many categories of different carton materials have what uses? Carton material is roughly divided into facial paper, lining paper, corrugated paper, core paper. Today's life, we often see the carton is usually a simple design of the counter box, but Zhangjiakou carton can be customized according to customer requirements to different specifications, shapes and materials of the carton.
What are the uses of carton materials
The cartons we often see are usually simple counterparts of the design of the box, but we can also according to customer requirements to customize different specifications, shapes and materials of the carton.
The use of the carton determines its design principle, the design is mainly on the corrugated and material of the carton.
First of all, we design the corrugated carton according to the characteristics of the items held in the carton, the transportation environment, the pressure strength to design the corrugated carton, according to the number of corrugated carton to determine the number of layers, generally divided into three layers, five layers and seven layers, the three-layer is more common. The carton material is divided into A, B, C three, but also according to the items held in the carton to determine the materials used, generally speaking, clothing and other cartons with a three-layer BC surface can be, such as home appliances and other heavy items should be used five AB surface, because of its high compressive strength.
Zhangjiakou Carton Factory grasp the trend of the times, making the carton quickly occupied the market for paper packaging containers. Zhangjiakou Carton Packaging Co. All employees are always in line with the "quality first, customer first" principle of first-class cartons, sincere service, waiting for the country from all walks of life, new and old customers to negotiate patronage.
