Wrapping Paper Gift Set What effect does wrapping paper gift set have on printed products?

The GRAIN of the paper refers to the DIRECTION of the paper fiber, which is parallel to the DIRECTION of the paper MACHINE, also known as the vertical direction, that is, the MACHINE DIRECTION (MD), and the vertical direction of the paper machine is called the CROSS DIRECTION (CD). Many properties of paper have significant directivity. Longitudinal direction (MD) tension and kneading resistance is strong, and the tear is weak, easy to tear off, because the grain is longitudinal, transverse direction is more difficult to tear off. After the web is cut flat, its GRAIN has two names: 1, LONG GRAIN, also known as straight grain, referred to as LG, its grain along the long side, that is, the paper fiber is parallel to the long side. 2, SHORT GRAIN, also known as horizontal grain, SG for short, the grain runs along the short edge, that is, the paper fiber is parallel to the short edge. The natural grain of paper is an absolute concept, which is different from the grain of paper embossing. The long or short grain of paper is a relative concept, relative to the size of the paper. If a positive paper is long grain, folio is short grain.

Therefore, in the printing process, if you do not pay attention to the grain of the paper, the effect of printing can be very different. Especially box or bag printing. Some printing plants in order to save costs, regardless of the paper grain direction, at the time of opening the paper, the production of some packaging boxes are tough, but some packaging boxes are more fragile, some packaging boxes are always easy to break, and some packaging boxes with a long time will not have problems. Especially handbag printing, a large part of the handbag is Ding three open, the horizontal opening of the third of the paper grain and vertical open paper grain is very far. If the paper itself is not good paper, the difference is even greater. High-grade printing absolutely can not appear such products. Some printing salesmen do not understand this truth for a few years, obviously are the same paper, why do the effect of some strong, and some weak it; Some edges are always broken, while others remain intact. Some edges are rough inside, while others are smooth and clean.
