Printing method and design points of vacuum packaging bags

Vacuum packaging bags generally use two printing methods: gravure printing and flexographic printing. gravure printing is a direct printing method that directly imprints the ink contained in the gravure pits onto the substrate. Flexographic printing, on the other hand, uses an elastic convex printing plate to transfer ink onto the substrate, and each printing method has its own characteristics. So, what are the printing methods and design points for vacuum packaging bags?

The design of vacuum packaging bags before printing should follow the following two principles:

(1) The small text and lines on the packaging bag should be designed as a single package to avoid inaccurate printing of multiple colors. The width of fine lines cannot be less than 0.1mm, otherwise they are prone to loss or unclear strokes during printing. The net height of Chinese fonts shall not be less than 1.8mm, and the net height of English fonts shall not be less than 1.5mm.

(2) Special attention should be paid to the reversed white text on vacuum packaging bags during design. If the text is small, especially when the strokes are thin, monochrome should be used. Attention should also be paid to the selection of fonts, such as round head font, bold font, and contour font. However, fonts with significant differences in strokes, such as Song font and Old Song font (thin horizontally and thick vertically), should be used with caution. If this font is used in the design, it should be noted that the net height of Chinese fonts should not be less than 2.5mm, and the net height of English fonts should not be less than 2mm.
