AIn the modern logistics and packaging industry, corrugated packaging boxes occupy an important position because of their environmental protection attributes and cost advantages. At present, RSC (standard slotted box) and RETT (double corrugated box) are widely used in the market, and there are significant differences in structure design, material cost and application scenarios, which provide multiple references for enterprises to choose packaging solutions.
Structural and protective performance
As a traditional standard slotted box, RSC adopts single or double wall corrugated cardboard structure, and realizes rapid assembly through prepressed folding lines, which is suitable for batch processing in automated production lines. It is characterized by strong compression resistance. The single-wall model can bear about 5-10kg weight, and the double-wall model is increased to 15-25kg. It is widely used in the transportation of conventional goods such as electronic products and clothing. RETT corrugated paper mail boxes feature a double-layer thickened design. Some products are made of 2mm thick cardboard and combined with matte or glossy lamination processes, offering superior moisture resistance and cushioning performance. They are particularly suitable for long-distance transportation of precision electronic devices such as laptops and tablets.
Cost and Environmental Characteristics
In terms of cost, RSC achieves lower unit prices through standardized production. Market data as of June 2026 shows that the unit price range for industrial-grade RSC corrugated cartons is 0.47 - 1.29 yuan, with a minimum order quantity of 1,000 units; RETT mailing boxes, due to their thickened materials and complex manufacturing processes, generally have a unit price ranging from 1.02 to 2.30 yuan, with a minimum order quantity of 500 pieces. In terms of environmental protection, both use recycled materials as the base material. The recycling rate of RSC can reach over 85%, while RETT reduces ink usage through embossing UV technology, further lowering carbon emissions. A certain packaging industry report indicates that the average logistics cost of enterprises using RSC packaging is reduced by 12%, while the damage rate of RETT is 30% lower than that of ordinary cartons.
Application scenario differentiation
RSC is suitable for high-frequency and standardized e-commerce shipping scenarios, such as lightweight goods like clothing and daily necessities. RETT is more competitive in the field of high value-added products. For example, the custom color printed RETT carton, which is popular in 2026, combines protection and brand display functions through screen printing and logo embossings. Although the unit price is 1.85-2.58 yuan, it is still favored by the skin care and 3C accessories industries. It is worth noting that with the stricter environmental regulations, the utilization rate of recycled materials in RSC has increased from 60% to 75% since 2022, which forms a differentiated competition with the ecological and environmental positioning of RETT.
Industry experts suggest that enterprises should consider product characteristics, transportation distance and brand image when selecting products: fragile and high-end goods should give priority to the enhanced protection of RETT, while large quantities of conventional goods can be optimized by RSC. In the future, with the advancement of corrugated paper material technology, the two types of packaging boxes may further integrate in terms of lightweight and high-strength performance.
