The core technologies in the design of paper packaging structures

In the field of paper packaging, structural design is a crucial aspect that directly affects the functionality, protection, and aesthetics of the packaging. The following will elaborate on the core technologies in the design of paper packaging structures.
Buffer structure design
The product will face various impacts and vibrations during transportation and storage, and the design of the buffering structure is to effectively absorb these external forces and protect the product from damage. Common cushioning structures include corrugated cardboard structures. Corrugated cardboard provides excellent cushioning performance through unique waveform structures such as A, B, C, etc. Different types of corrugated cardboard have differences in height, cushioning capacity, and compressive strength. For example, A has a high height and good cushioning performance, making it suitable for packaging large and fragile products; B-ribs are relatively fine and have high compressive strength, commonly used for packaging products that require high space requirements and certain protection.
In addition to corrugated cardboard, special cushioning structures can also be designed, such as foldable pulp molded cushioning pads inside packaging boxes. This type of cushion can be customized according to the shape of the product, closely fitting the contour of the product and providing comprehensive protection.
Self locking structure design
The self-locking structure enables paper packaging to maintain a stable shape without the need for additional glue or tape after assembly. This not only improves the assembly efficiency of packaging, but also reduces environmental pollution. Common self-locking structures include tongue locking and lock locking.
Tongue type self-locking refers to the matching design of tongue and slot on the box cover and body of the packaging box. When assembling, the tongue can be inserted into the slot to achieve tight fixation. This structure is simple and easy to operate, and is widely used in various types of paper box packaging. Lock type self-locking is a design that uses a structure similar to a buckle to fasten different parts of the packaging box together, providing a stronger fixing effect. It is commonly used for packaging that requires significant external force, such as cardboard boxes used for transportation.
Display structural design
In the process of product sales, a good display effect can attract consumers’ attention and enhance the competitiveness of the product. Display structure design aims to highlight the characteristics and advantages of the product, allowing consumers to visually see the product. Open window design is a common display structure that directly displays part or all of the product by opening windows on the packaging box, allowing consumers to have a clear understanding of the product’s appearance. The shape and size of the window can be designed according to the characteristics of the product, for example, circular windows are suitable for displaying circular products, and irregularly shaped windows can increase the uniqueness of the packaging.
In addition, some foldable display rack structures can also be designed. This structure can be folded up during transportation to save space, and when it reaches the sales location, it unfolds into a display rack to showcase the product on the shelf, which not only facilitates transportation but also improves the display effect of the product.
Convenient opening structure design
For consumers, easy to open packaging can bring a better user experience. The convenient opening structure design should take into account consumers’ usage habits and strength. Easy to tear design is a common and convenient way to open the packaging box. A line that is easy to tear is designed at the seal of the packaging box, and consumers only need to gently tear it to open the package. To increase the strength and stability of the tear prone area, reinforcing strips can be added at the tear prone area.
In addition, the pull tab opening structure is becoming increasingly popular. This structure allows consumers to easily open the packaging by installing a pull tab on the packaging box. It is suitable for larger packaging boxes or packaging that requires greater opening force.
The core technology of structural design for paper packaging covers multiple aspects such as buffering, self-locking, display, and convenient opening. By using these technologies reasonably, paper packaging with complete functions, beautiful and practical appearance can be designed to meet the packaging needs of different products.
