Bird Feed Jute Sack Manufacturing. Introduction: Jute is a long, soft, shiny vegetable fiber that can be spun into coarse, strong threads. It is produced primarily from plants in the genus Corchorus, family Tiliaceae. Jute is one of the cheapest natural fibers and second only to cotton in the amount produced and variety of uses. Jute sacks are commonly used for storing and transporting grain and other agricultural products. They are also used for packaging food items such as coffee, tea, and spices. Jute sacks are also used to make carpets, rugs, and other home furnishings. The manufacturing process of jute sacks involves several steps. Jute plants are first harvested and the fibers are extracted. The fibers are then spun into threads which are woven into fabric. The fabric is then cut and sewn into sacks of various sizes. Jute sacks are a cheap and durable option for packaging and storing products. They are also biodegradable and environmentally friendly.
