Packaging design experience sharing

Packaging design covers a wide range of topics, from the design of the structure of the form, the use of fonts in the content, and the choice of different materials for the package. In general, packaging design can be said to include all aspects of it. The following and share some of my experience on packaging design.
First, the packaging color.
According to the different packaging materials, we need to pay attention to: as aluminum – plastic flexible packaging and aluminum – paper flexible packaging has opaque, can be considered in accordance with the conventional color. But for single-layer polyethylene packaging such transparent packaging, you can consider the color of the contents as a complementary color for printing, the color of the contents can be used as a pattern background, or as an accent color (window color) can be.
The color of liquid items, solid size granular items can be used for the background color of flexible packaging, this packaging is recommended to leave a transparent window on the package, or a single-sided printing full version of opaque color, the back only printing instructions text, so that the contents are transparent and visible.
Second, the content of the package on.
Bar code must have a contrast obvious background color, not to use the contents as a background, so as not to read the code reader can not read.
The text has no strong rules, as long as to ensure that the contact surface with the food is not printed on. The artistry of the text is the space for the design to play. The size of the text, the name of the product can be larger, but still depends on the size of the bag, but also artistic treatment, that is, some text deformation and so on. Description text can be smaller, but the minimum can not be less than 2.5mm, or invisible. All the text should contrast with the background color, so that can be clearly readable.
Third, the packaging of the white, this is no hard and fast rules, also belongs to the category of design creativity, as long as you follow a principle can be, good-looking, can attract the purchase is good.
