How Lokta Paper Is Made: From Himalayan Bush to Handmade Sheet

High in Nepal's middle hills, between 5,000 and 10,000 feet altitude, grows the Daphne bush — an unassuming shrub whose inner bark has been transformed into one of the world's most remarkable papers for over a millennium. The process remains entirely handmade, chemical-free, and sun-powered.

The Daphne Bush

Two species of Daphne provide the raw material for Lokta paper: Daphne bholua and Daphne papyracea. Both grow wild in Nepal's hill forests, primarily in the Baglung, Myagdi, Parbat, and Dolakha districts. The bushes reach 6-12 feet in height and produce long, fibrous inner bark that is the papermaking material. Crucially, Daphne bushes regenerate from their root system after bark harvesting — the plant is not killed, and new shoots grow within a year. Full bark regrowth takes 5-7 years, making Lokta one of the most sustainable fiber sources in the world. The Nepali government regulates harvesting through community forestry user groups to ensure long-term sustainability.

Bark Harvesting

Harvesting takes place during the dry season (October-March) when bark strips most easily. Villagers trek into the forest, select mature Daphne bushes (typically 3+ years of bark regrowth), and carefully strip the outer bark to reveal the inner bast fibers. The inner bark is peeled off in long strips, bundled, and carried back to the village — often several hours' walk through steep, roadless terrain. A single harvester can collect 15-25 kg of wet bark per day. The bark is initially air-dried in the village before further processing.

Cooking the Bark

The dried bark strips are soaked in water for 24-48 hours, then boiled in a large iron cauldron with wood ash (a natural alkali) for 4-6 hours. The wood ash dissolves the non-cellulose components (lignin, pectin) that bind the fibers together, leaving behind pure cellulose fibers. This is the only 'chemical' used in the entire process — wood ash from the cooking fire. No bleach, no synthetic chemicals, no acids. After boiling, the softened bark is rinsed in clean water to remove ash residue.

Beating the Pulp

The cooked bark fibers are spread on a flat stone slab and beaten with wooden mallets until they break down into a smooth, even pulp. This beating process — done entirely by hand — takes 1-2 hours per batch. The quality of beating determines the final paper quality: thorough beating produces smooth, even sheets, while less beating creates a more textured, fiber-rich paper. For specialty papers with visible fiber texture, beating is intentionally kept minimal.

Forming the Sheets

The beaten pulp is mixed with clean water in a shallow vat to create a slurry. A rectangular wooden frame — typically 50x75cm — covered with fine muslin cloth is dipped horizontally into the vat, collecting an even layer of pulp on its surface. The amount of pulp collected determines the paper weight (GSM). The frame is then carefully removed and placed in direct sunlight to dry. This sun-drying takes 4-8 hours depending on temperature and humidity. The UV in sunlight naturally whitens the paper slightly and helps bond the fibers.

The Finished Sheet

Once fully dry, the paper sheet is gently peeled from the muslin cloth on the frame. Each sheet has two distinct sides: the face side (which was exposed to the sun) is smoother, while the mold side (which sat against the muslin) has a subtle fabric texture. Both sides are usable. The sheets are inspected for consistency, graded by weight and quality, and stacked for transport to Kathmandu, where they are sold as raw material to papercraft workshops or shipped directly to international buyers.

Why Lokta Paper Lasts

Lokta paper's legendary durability comes from several factors. The Daphne bark fibers are naturally long (up to 3cm), creating a strong interlocking paper structure. The paper is naturally acid-free — unlike wood-pulp paper, which contains lignin that causes yellowing and eventual disintegration. And Daphne bark contains natural compounds (daphnin and other coumarins) that are toxic to insects, giving the paper built-in resistance to bookworms, silverfish, and other paper pests. This combination of long fibers, acid-free chemistry, and natural pest resistance explains why Lokta documents in Nepal's national archives remain intact after more than 1,000 years.
