1.Personalized Customized Structure
In order to meet the unique shapes and display requirements of different high-quality products, personalized packaging structural design is necessary. For example, for high-end artworks with irregular shapes, the packaging structure should closely fit the contour of the product to prevent it from moving during transportation and display. This may involve using 3D scanning technology to obtain the precise shape data of the product and then using computer-aided design (CAD) software to model and optimize the packaging structure.
For instance, for a crystal sculpture with a complex shape, packaging designers can use 3D scanning to obtain the three-dimensional model of the sculpture. Then, based on this model, a multi-layer nested paper box structure can be designed. The outer paper box can provide basic protection and brand display functions, while the inner layer can precisely fix each part of the sculpture through customized grooves and cushioning materials to ensure its stability during transportation.
2.Functional Structural Design
High-quality packaging often needs to have multiple functions, such as being easy to open, convenient for taking out products, and having anti-theft features. The easy-to-open structure can adopt a special tear opening design, which allows consumers to easily open the packaging while ensuring its integrity. For example, in some high-end food gift boxes, a sealing sticker with an easy-tear line will be designed at the sealing position. Consumers only need to pull it gently to open the gift box.
For high-quality packaging that requires anti-theft features, such as the packaging of high-end electronic products, anti-counterfeiting seals and special locking structures can be used. This kind of locking structure can firmly lock the packaging when it is not damaged. Once it is illegally opened, obvious marks will be left, thus ensuring the security of the product.
3.Space Utilization and Stacking Design
During transportation and storage, the space utilization efficiency and stacking stability of packaging are very important. The structural design of high-quality packaging should consider the reasonable layout of products in the packaging to reduce space waste. Meanwhile, the shape of the packaging should be designed to be easy to stack. For example, regular shapes such as cuboids and cubes can be adopted, and matching stacking structures such as grooves and protrusions should be designed at the bottom and top of the packaging to ensure that it will not tip over when stacked.
For example, in the high-quality packaging of wine, the placement of wine bottles and the design of the internal compartments of the paper box should fully consider space utilization. The paper box can be designed to accommodate multiple bottles of wine, and the distance between the compartments should be appropriate. It can not only fix the wine bottles but also ensure the stability of the entire packaging when stacked, reducing the risk of damage during transportation.
1.Paper Processing Technology
Surface Treatment Technology: In order to enhance the texture and visual effect of high-quality packaging, various paper surface treatment technologies are adopted. For example, hot stamping technology can make the packaging surface present patterns or words with a metallic texture. Metal foil is transferred to the paper surface through high temperature and high pressure. It is often used for highlighting the logo of high-end cosmetics gift boxes and brand logos. Embossing technology uses special molds to emboss various textures on the paper surface, such such as leather textures and wood textures, making the paper look more textured and increasing the high-end feel of the packaging.
2.Coating Technology: Applying a special coating on the paper surface can endow the paper with different properties. For example, a moisture-proof coating can prevent the packaging from being damaged by moisture in a humid environment, which is very important for the packaging of some high-end tea, tobacco and other products. The oil-proof coating is suitable for packaging food containing grease, such as high-end chocolate gift boxes, to prevent grease from seeping out and affecting the appearance of the packaging and the quality of the product.
3.Composite Material Technology
High-quality packaging often uses composite materials to combine the advantages of different materials. For example, combining paper with plastic film can have both the printability of paper and the moisture-proof and flexibility of plastic. This composite material can be used to make the window part of the windowed paper box, allowing consumers to see the product while ensuring the overall performance of the packaging.
In addition, paper can also be combined with metal foil and used in the packaging of some high-end electronic products that need to shield electromagnetic interference or to increase the metallic luster and barrier properties of the packaging. For example, in the packaging of some high-end smart watches, a paper-aluminum foil composite material is used, which can not only protect the watch from electromagnetic interference but also enhance the texture of the packaging.
Material Forming Technology
During the production of high-quality packaging, paper or composite materials need to be processed into various shapes. For the forming of paper boxes, high-precision die-cutting technology is the key. The die-cutting process can accurately cut the paper into the required shapes and sizes, and can also perform creasing operations at the same time, facilitating the folding and forming of the paper box.
For some packaging with special shapes, such as irregular-shaped paper boxes, thermoforming technology may be adopted. Thermoforming is to heat plastic sheets or composite materials to a softened state and then form them through molds. This technology can produce complex shapes, such as packaging with curved and concave-convex structures, to meet the creative design requirements of high-quality packaging.
1.High-precision Printing Technology
High-quality packaging has high requirements for printing precision to ensure clear and exquisite patterns and words. Offset printing is one of the commonly used high-precision printing technologies. It can print high-quality color images and delicate words. By using high-quality inks and fine printing plates, offset printing can achieve vivid colors and distinct layers of printing effects. For example, on the packaging of high-end perfume gift boxes, offset printing can accurately reproduce the logo of the perfume brand and exquisite flower patterns, enhancing the visual appeal of the packaging.
Digital printing technology is also being increasingly used in high-quality packaging. It has the advantages of high flexibility and being able to realize small-batch customized printing. Digital printing can quickly print personalized packaging according to different design requirements and can ensure relatively high printing quality. For some limited-edition high-quality packaging or product packaging that needs to frequently update the design, digital printing is a good choice.
2.Special Printing Technology
UV Printing Technology: UV printing uses ultraviolet-cured inks during the printing process. This kind of ink can quickly solidify under ultraviolet irradiation. UV printing can achieve some special effects, such as local gloss and a raised tactile feel. In high-quality packaging, it is often used to highlight the key information of products or brand logos, making them more conspicuous on the packaging. For example, on the packaging of high-end electronic products, the product name is printed with a raised effect through UV printing, which not only enhances the visual impact but also gives consumers a tactile experience.
Anti-counterfeiting Printing Technology: In order to prevent high-quality packaging from being counterfeited, anti-counterfeiting printing technology is crucial. Common anti-counterfeiting printing technologies include anti-counterfeiting ink printing and holographic anti-counterfeiting printing. Anti-counterfeiting inks can be color-changing inks, fluorescent inks, etc., which change color or emit fluorescence under specific conditions (such as light irradiation, heating, etc.) to verify the authenticity of the packaging. Holographic anti-counterfeiting printing prints holographic patterns with three-dimensional and rainbow-like color changes on the packaging. This kind of pattern is difficult to copy and is an effective anti-counterfeiting means. For example, on the packaging of high-end liquor, holographic anti-counterfeiting printing technology is used to print the brand's unique holographic patterns on the wine bottle labels or paper boxes. Consumers can distinguish the authenticity of the product by observing the integrity and color changes of the patterns.
