In the world of paper, some grades attract attention for their distinctive finish or specialist applications. But there is one grade that rarely wins on appearance alone, and yet ranks among the highest-volume, most widely used papers in the printing industry — woodfree offset paper, known in Chinese as 双胶纸 (shuāng jiāo zhǐ).

The name reflects the manufacturing process: both sides of the sheet are surface-sized, a treatment that tightens and smooths the paper's surface, significantly improving ink holdout and writing performance. Because both sides receive this treatment, the paper performs consistently on both faces — which is precisely what the name describes, and precisely what makes it so versatile.

Many everyday papers are either single-sided sized or entirely untreated at the surface, which causes ink to penetrate unevenly, writing to feather, and printed detail to lose sharpness. Woodfree offset paper's double-sided sizing creates a uniform surface layer that regulates ink absorption, producing cleaner halftone dots, sharper text edges, and more accurate reproduction of fine detail.

Compared to coated paper, woodfree offset has no coating layer. It retains the natural fibre texture of the paper itself — soft to the touch, matte, and non-reflective. Extended reading does not cause the eye strain that can come with the high-gloss surface of coated grades. This quiet, natural quality is one of the primary reasons it has remained the material of choice in book publishing and cultural print for decades.

Woodfree offset paper does not aim to dazzle. It aims to ensure that every act of writing and printing is accurate, clear, and comfortable. That straightforward reliability is why it has remained the market standard year after year.

Book publishing is where woodfree offset paper is consumed in the greatest volume. Textbooks, literary titles, reference works, children's books — the vast majority use woodfree offset for their text pages. Its matte, non-reflective surface performs well under both natural and artificial light, its whiteness is well-calibrated for extended reading comfort, and it has been the default choice of the publishing industry for generations.

The printing industry is an equally significant market. Product instruction manuals, operating guides, report interiors, and contract documents — applications that require print precision without the reflective finish of coated paper. Woodfree offset's matte surface is well-matched to this range of needs, and its cost sits comfortably below coated alternatives, making it a practical choice for high-volume document printing.

Demand from the office and stationery sector is equally consistent. Copy paper, printer paper, notebook pages, letterhead, notepads — wherever writing or printing takes place, woodfree offset is almost always present. It is compatible with water-based inks, oil-based inks, laser printing, and inkjet printing alike, making it the most universally applicable choice for office paper applications.

The packaging industry is also an increasingly active user of woodfree offset. Interior liner sheets, separator paper, in-box instruction printing, and the outer surfaces of brand packaging that emphasises a natural, tactile aesthetic — woodfree offset's warm, matte quality makes it a compelling alternative to coated paper for brands whose visual language calls for an understated, natural tone.

Woodfree offset paper is available across a wide grammage range, from 60gsm to over 120gsm, and the right choice depends primarily on the intended use. Book text pages are typically specified at 70 to 80gsm — sufficient opacity to prevent show-through, while keeping overall book weight manageable. Instruction manuals and report interiors generally call for 80 to 100gsm, which provides enough body to hold its shape when handled. Standard office copy and print applications are most commonly served by 70 to 80gsm. For archival documents or high-quality publication interiors where a premium feel is expected, 100gsm and above offers a noticeably more substantial hand and a stronger impression of quality.

Songhong Paper supplies woodfree offset paper across multiple grammage specifications, with consistent whiteness, high flatness, and reliable batch-to-batch uniformity — well suited to the volume purchasing requirements of printers, publishers, packaging manufacturers, and office supply procurement teams. Every batch is subject to rigorous quality control covering whiteness, grammage, and surface smoothness, so your print and writing results remain consistent across orders.
