There are many types of paper available in larger cities in Nepal. However, the paper made by traditional methods is still considered the strongest and most durable of all. Because of its durability, Nepali paper is still a thriving small industry.
The traditional method doesn't need high tech equipment, machines, or electricity. All one needs is the skill and locally available products: stones, wood, water, and the availability of tree bark harvesting. Also, traditional Nepali paper is stronger and longer lasting than conventional, industrially processed Nepali paper and as a result is commonly used for official letters and documents.
In the Eastern region of Nepal, there are two paper processing areas that I knew of. One is the district that I lived in (Sankhuwasabha). A local entrepreneur with connections in Kathmandu (a retired ghorka army soldier) established a factory out of his house. The man receives orders from Kathmandu and the employees work all day and most of the night to make the paper for the order. After the paper is made it is tied and bound in large volumes. The packages (weighing around 50 kilograms each) are then carried by porter to the roadhead three days away. From there the paper continues by bus or truck into Kathmandu. In Kathmandu, the paper is sold as is or cut into working sizes for retail and/or redistribution.
