Coated duplex board with white back stands out as an excellent material for packaging and printing due to its core characteristics of combining functionality with 100% environmental friendliness. Made from high-quality 100% recycled pulp and waste paper pulp, it practices sustainable development concepts from the raw material stage, reducing the consumption of virgin wood and alleviating pressure on forest logging, while responding to modern market demands for eco-friendly packaging through resource recycling, making it an ideal choice under the trend of green economy.

In terms of craftsmanship, coated duplex board with white back innovatively adopts double-sided coating technology, with both sides finely treated at the micrometer level to form a uniform and symmetrical honeycomb pore structure. This special construction not only makes the surface smooth and flat, with a touch as delicate as silk, but also fundamentally solves printing issues such as ink penetration and bleeding. Even when performing full double-sided printing, it maintains color saturation without color bleeding and sharp text edges without blurring, presenting product information more intuitively and accurately, especially suitable for scenarios requiring double-sided display such as blister cards, color cards, and color boxes.

In terms of practicality, coated duplex board with white back offers multiple grammages of 300g, 350g, 400g, and 450g, allowing flexible adaptation to different needs. Lightweight 300g is suitable for exquisite product packaging cards, while 450g can be chosen for heavy electronic accessory packaging to enhance load-bearing capacity. It covers a wide range of products including color boxes, blister cards, food boxes, menus, calendars, and hang tags, balancing stable physical properties and visual aesthetics.

Printing compatibility is another highlight, as it accurately reproduces every texture of the design draft whether it's the delicate gradient of offset printing, the vivid colors of flexography, the deep layers of gravure printing, or the three-dimensional tactile feel of UV printing, providing ample space for creative design.

In terms of quality assurance, duplex white paper has passed multiple international certifications including FSC, EUDR, SGS, and MSDS: FSC Recycled 100%, EUDR makes tracing easier and more convenient, while SGS and MSDS reports verify the safety of the product when in contact with clothing, medicine boxes, and other products. With multiple certifications, it meets global market compliance standards and provides reliable quality endorsements for brands, becoming a material example that balances functionality, environmental friendliness, and safety. 

Note: Due to the batch differences in de-inking pulp and waste paper, there may be slight differences in fiber distribution and color between batches, which is a normal phenomenon for this product.
