The journey of a non woven bag

0
1K

Once the materials are selected, the manufacturing process commences with the melting of polypropylene pellets. These pellets are heated to a high temperature until they transform into a viscous liquid. This molten plastic is then extruded through a spinneret, which forms continuous filaments. These filaments are laid down in a web-like structure, creating the foundation of the non woven bag. This process is known as spunbonding, and it is one of a common methods used in the production of non woven bags.

After the fibers are laid down, they undergo a bonding process. There are several techniques for bonding the fibers together, including thermal bonding, chemical bonding, and mechanical bonding. Thermal bonding is a widely used method, where heat is applied to fuse the fibers, creating a strong and cohesive fabric. This step is essential as it enhances the strength and durability of the non woven bag, allowing it to withstand various stresses during use.

Once the bonding is complete, the fabric is then treated to improve its properties. For instance, some non woven bags may undergo a water-repellent treatment, making them suitable for carrying items that may get wet. Additionally, the fabric can be printed with vibrant colors and designs, allowing for customization that appeals to consumers. This versatility is one of the reasons why non woven bags have become a popular choice for businesses looking to promote their brand in an eco-friendly manner.
