Bag printing paper specifications paper specifications are what generally based on the type, size, weight to calibrate. (1) bag printing paper type of printing paper in the paper version of the paper is divided into two types of web peace. Only web width calibration, no length setting, is typically used is high even rotary press. Flat paper has a long and broad set of non-woven bags, mostly used in printing paper plate. (2) the weight of the paper bag printed paper weight as well as the quantitative and so heavy that the usually quantified. Quantitative known as weight, is the weight per unit area of ??the paper, the unit is the number of grams per square fans, such as weight per square meter of the paper is 60 grams, usually 250 or less per square meter called paper, 250 grams per square meter referred to above as cardboard. In the printing industry, indicates the paper weight of the unit as well as make important creative non-woven bags, the unit is kg (kilogram). Order a heavy paper of 500 full paper. Quantitative and format depending on the paper size, using the following formula to make weight and quantitative conversion: Order weight (kg) = paper area (m2) × 500 quantitative (g / m2) ÷ 1000 film bag printing concept: in mounted on the paper layer of transparent plastic film is coated. Specifically, as product brochures printed in the cover, the outer surface of the carton easy to wear these parts, if you need the protective film material non-woven bags, just after printing, folding, and trimming before giving it mounted one, which layer film must be transparent, has good toughness, uniform texture, no trachoma bubble, the surface is very smooth, it is usually made of a polypropylene material, it also pre-applied adhesive thermoplastic polymer and paper in order to combine printing plant with hot rollers to it firmly affixed to the paper. Thus, the surface of the paper has a better luster, texture and thicker non-woven bags made and printed on the top of the color is protected. We saw earlier, glazing have the same effect, but the thick paper coating becomes brittle, but become flexible folding after lamination. Category: Today's coated paper covers are generally required to film, high-end cartons and bags, covers product brochures and corporate brochures, calendars trademark on clothing, ...... also covered. You will find the film, there are two, one is bright as a mirror, one is not very reflective, which are called "light films" and "dumb film." Most transparent bright film, almost no effect on the ink, but it's sometimes not very flattering reflection, such as handbag cover after the film shiny, slightly deformed after loading things will look very soft, very low, calendar does not apply bright film, because it interferes with the line of sight, but on a flat surface hardcover book covers, cardboard boxes, the effect is bright as a mirror is good; the texture of thick steady dumb film, the film is generally believed that it is more than light high-end, its price is more expensive, but it looks like that will affect the ink varnish, very picky colors, such as people's skin, a little biased some of the corporate color will not work, and it is not appropriate to use dumb film.
