Packets Of Paper Types And Characteristics Of Commonly Used
China is the world's largest tobacco producer, with annual output of 34.45 million large box. Most of these cigarettes are used Carton Packaging, paper type mainly white cardboard, white paper, coated paper and aluminum foil. If the country by 34 million big boxes, soft, hard box packaging at 50% of all the four varieties of paper for the annual sales: 490 thousand tons of white cardboard, white paper, 300,000 tons, 68,000 tons coated paper, aluminum foil 105,000 tons. In recent years, strong development momentum of the hard box packaging, therefore, increasing the amount of white cardboard. The extensive use of aluminum foil paper, it is a strong performance with Chinese characteristics, whether hard or soft pack bag, whether a class and second class smoke, or low end of the four, five smoke, have adopted gorgeous, high-cost aluminum foil. The occurrence of this phenomenon has greatly promoted China's aluminum foil production enterprises. Although this result Romance of a cigarette case to some extent "excessive packaging" in the flood, but also heavy Chinese cigarettes, elegant performance most vividly, the world Packets Areas of new eyes.
The following are commonly used in paper packets of the types and standards.
A white cardboard Thick white cardboard is a strong, quantitative large thick. As the surface is not colored, often called white cardboard.
China's white cardboard divided into A, B, C three levels. A whiteness of not less than such 92%; B, which are not less than 87%; C, which are not less than 82%.
White cardboard raw material is 100% bleached chemical wood pulp, which is the best bleached softwood kraft paddle, or accompanied by some of bleached hardwood kraft paddle.
Packets of white cardboard require high stiffness, bursting strength, smoothness and whiteness. Paper required level, and not to have streaks, spots, uneven, production of warpage. As the packets of white cardboard. Mainly web gravure printing machine to print, so the anti-white cardboard targets require a higher tension. Tensile strength, also known as tensile strength or tensile strength, which means that the fracture of paper can bear the greatest tension to kN / m, said. Gravure printing machine is holding when starting roll, high-speed printing should bear a greater tension, often break if the paper is inevitably result in frequent downtime and reduced efficiency, but also increases wear and tear the paper.
White cardboard packets are two types, One is the FBB (yellow core), a is the SBS (white core), using the FBB and SBS packets are single coated white cardboard. FBB formed by the three pulp, surface layer and the underlying use of sulfate Wood pulp Core layer of the use of chemical mechanical wood pulp mill. Positive (print side) as coating layer, using two or three scraper coating, no coating layer opposite. As the middle layer is the chemical mechanical pulp mill, this pulp slurry timber was high (85% -90%), production costs are lower, therefore, FBB made of cardboard and relatively low price . This long-fiber pulp in many small fibers, fiber bundles less, as the thickness of paper is good, therefore, the same weight of FBB much thicker than the SBS. SBS usually carried out by three plasma composition, surface layer, core layer, the underlying use bleach kraft pulp. Front (print side) of the coating layer, with the FBB also use two or three times as blade coating, no coating layer opposite. Also used as core layer bleached kraft pulp, high whiteness, so called white core. Meanwhile, the pulp fiber small, large paper tightness, SBS FBB than the thickness of the same gram much thinner. For example, the Hongta Yanlord of 230g/m2 FBB, the thickness of 320 m, and 230g/m2 of SBS, the thickness of 295 m.
2, Single White Cardboard The past, also known as single-sided white board paper white board paper. Single positive quality white paper must be white and smooth, well organized, good stiffness, easy to fluff when printing, less stretching deformation, suitable for chromatic printing. Meanwhile, it has good folding, so as to ensure the pressure line when cutting indentation, straight edge lines will not cause paper breakage.
Single white paper by the multi-layer composite sheet made of the quality of each layer requires several different slurry.
