Description

[Technical Field]

[0001] This utility model relates to a packaging box, specifically an integrated, non-adhesive, snap-on packaging box, belonging to the field of packaging material technology. [Background Technology]

[0002] Fresh produce such as fruits and vegetables requires high-performance packaging boxes during transportation. These boxes must possess sufficient mechanical strength to ensure stacking stability, while also considering factors such as moisture resistance, breathability, lightweight design, and cost-effectiveness. Currently, the most widely used transport packaging on the market includes traditional corrugated cardboard boxes and injection-molded plastic crates, both of which have significant limitations.

[0003] Traditional corrugated cardboard boxes are made of paper and typically require the use of sealing studs, tape, and other auxiliary materials for sealing and securing. This method is cumbersome, incurring high labor and material costs, and is inefficient. More seriously, cardboard boxes have poor moisture resistance, easily absorbing moisture and softening in cold chain or high-humidity environments, leading to a sharp decrease in compressive strength and potentially causing box deformation, damage, or even spoilage of the contents. Furthermore, cardboard boxes often have insufficient ventilation, especially in enclosed transport environments where moisture and heat can accumulate, affecting the quality of fruits and vegetables. Although cardboard boxes offer advantages such as being foldable when empty and easy to recycle, their poor durability and low reusability limit their application in high-end logistics.

[0004] Injection-molded plastic crates offer excellent waterproof and moisture-proof properties as well as structural strength, allowing for multiple reuses. However, their drawbacks are equally significant: First, injection-molded crates are typically rigid structures, taking up considerable space when empty and resulting in extremely high costs for return transport. Second, high mold costs and energy-intensive production processes hinder flexible applications in small to medium-scale settings. Third, their overall weight increases logistical burdens. Furthermore, ordinary plastic crates generally lack quick-folding and assembly capabilities, leading to poor convenience in use and storage.
