Shenhua Printing Plate Knife Pad: Low-cost biodegradable universal model, suitable for the environmental protection needs of small and medium-sized enterprises.

During the green transformation process of small and medium-sized enterprises, they not only face the pressure of environmental compliance but also are constrained by cost control. The conventional biodegradable elastic pads are relatively expensive, while low-cost pads do not meet environmental protection requirements and are difficult to achieve a balance between "environmental protection" and "cost". Shenzhou Printing Materials, based on the urgent environmental needs of small and medium-sized enterprises, has launched low-cost biodegradable universal knife plate elastic pads. Through formula optimization and process upgrading, while controlling costs, it achieves biodegradability, high precision, and helps small and medium-sized enterprises complete the green transformation at a low cost.

In terms of the balance between cost and biodegradability, using domestic bio-based biodegradable materials, with corn starch and natural rubber as the core raw materials, replacing expensive imported biodegradable materials, and at the same time through large-scale production and simplifying redundant processes, the production cost is reduced, and the product price is more than 45% lower than that of conventional biodegradable elastic pads, and is the same as that of ordinary low-cost elastic pads; optimizing the biodegradable formula, adding biodegradable accelerators, the elastic pad has a degradation rate of over 90% in the natural environment, with a degradation cycle of 180-270 days, no harmful residues, and obtaining EU OK compost and China environmental product certification, meeting environmental protection compliance requirements.

In terms of performance and compatibility, this elastic pad adopts standardized production control, with thickness error controlled within ±0.05mm, hardness fluctuation ≤ 3 Shore A, rebound rate ≥ 92%, compression permanent deformation rate ≤ 7%, and can be adapted to the common cutting scenarios of small and medium-sized enterprises (such as ordinary cartons, express bags, simple food packaging); covering common thicknesses of 1.0-2.5mm and common hardnesses of Shore A 45-65, no need for customization, can be directly purchased in stock, and is compatible with flat press flat and round press flat various common cutting equipment, without additional debugging. After a small packaging enterprise applied this solution, it successfully passed the environmental protection compliance review, the waste elastic pads do not require special treatment, and saves nearly 10,000 yuan in environmental treatment costs per year, and the comprehensive cost of consumables is reduced by 28%, perfectly balancing environmental protection and cost requirements.
