Compared with other ordinary white or other monochrome, black can not only cover up minor scratches or dirty marks, but also give people a deeper impression.

Environmental protection concept: green choice for sustainable development
As a responsible corporate citizen, Sanhai Packaging is always concerned about environmental protection issues and is actively engaged in the development of a new generation of greener packaging materials. The so-called "degradable plastics" refers to a class of polymer matrix materials that can be gradually decomposed into water molecules, carbon dioxide and other harmless substances in the natural environment. Such new materials can not only reduce the dependence on fossil fuel resources, but also help to alleviate the increasingly serious pressure of environmental pollution. At present, Sanhai has obtained a number of relevant certification certificates issued by domestic and foreign authoritative institutions, and has established a good reputation image in the industry. Many international brands have also begun to gradually adopt this new type of environmentally friendly packaging solutions to fulfill their social responsibilities with practical actions.

Flexible specifications: meet diverse packaging needs
In order to adapt to the changing demand trends in the market, Sanhai provides a wide variety of size options for customers to choose from. They range from small size models suitable for sending electronic accessories to large-capacity models large enough to hold clothes and shoes, covering almost all types of items that may be encountered in daily life. For small and medium-sized e-commerce sellers who face the dual challenges of inventory management and cost control, a reasonable stocking strategy is essential. It is suggested that some products of regular size can be hoarded before the promotion season. If non-standard customization is involved, the principle of on-demand purchase can be adopted according to the actual situation, which can not only ensure sufficient supply of goods but also avoid the occurrence of excessive backlog and waste of funds.

Direct Supply from Manufacturers: A Faster and Efficient Supply Chain Model
As a direct-to-end manufacturer, Sanhai Packaging is able to offer a more competitive pricing and service experience than traditional distribution channels. First of all, in terms of price, after removing the intermediate links, the final buyer can get more benefits. Secondly, it also has obvious advantages in service response speed. The whole process from placing an order and inquiring to the final delivery and delivery is completed in the shortest time. In addition, the perfect logistics distribution network covers all major cities and areas in the country, and even remote places can be delivered on time. Many customers who have cooperated say that it is precisely because of the choice of such a reliable supplier partner that they have been able to gain a firm foothold in the market and continue to grow.
