Food packaging bags belong to one of the food packaging materials testing categories, mainly made of plastic materials, such as polyethylene packaging bags, polypropylene packaging bags, polyester packaging bags, polyamide packaging bags, polyvinylidene chloride packaging bags, polycarbonate pack...
In addition to providing protection for food, the design of food packaging bags should also take into account the aesthetic feeling and can arouse the appetite of consumers. Let’s take a look at what aspects should be paid attention to in the design of food packaging bags.
1. Color Problem...
6、 Heat-seal leakage
Leakage is due to the existence of some factors, so that the parts that should be combined by heating and melting are not sealed. There are several reasons for leakage:
A: Insufficient heat-sealing temperature. The heat-sealing temperature required by the same packaging ma...
4、 Hot sealing extrusion PE problem
During the heat-sealing process of the composite film, PE is often extruded and stuck to the heat-sealing film. The more it accumulates, the more it affects normal production. At the same time, the extruded PE oxidizes and smokes on the heat-sealing die, givi...
2、 Friction coefficient problem
Friction in packaging is often both drag and resistance, so its size should be controlled within an appropriate range. Coils for automatic packaging are generally required to have a small internal friction coefficient and a suitable external friction coefficient. ...
Packaging machines can be divided into vertical and horizontal ones, and vertical ones can be divided into continuous (also known as roller type) and intermittent (also known as palm type) ones. Bagging can be divided into three side sealing, four side sealing, back sealing, and a number of lines...
8. Design of portable paper packaging box
This method is mainly to increase the handle of the package and design it into a portable package, so that the overall shape of the package will be greatly changed. This kind of full colors printed paper packaging box must be designed according to the wei...
5. Comparison of the curve and straightness of the main body of the paper packaging boxes
In paperboard packaging box’s modeling design, there are two main factors that affect paper cartons’ modeling: one is linear, the other is surface. The change of line shape will inevitably affect and produc...
1. Change the three-dimensional dimension method
This method is mainly suitable for paperboard boxes with variable packaging forms, such as granular, strip, powder, small piece, paste, liquid, combined shape and other products. As long as the one-dimensional, two-dimensional or three-dimensional...
Creative graphics are divided into concrete, abstract and decorative graphics. Figurative figure is a true portrayal of nature and a way to describe and reproduce things. Abstract graphics are used to express the connotation and theme of design with points, lines, surfaces and other elements, giv...
Application of Decorative Graphics
Decorative figures generally refer to deformed animals and plants and geometric images, with concise lines and highly generalized expressive force. Compared with concrete and abstract graphics, decorative graphics are more concise and refined, more fashionable, ...
Creative graphics have emotions.
It is not really said that emotions come from the graphics themselves. On the one hand, this emotion is affected by the designer’s subjective imagination and aesthetic level. On the other hand, consumers are affected by personal preference and aesthetic leve...
