PP Leno Bags are primarily made from polypropylene (PP), a lightweight yet durable thermoplastic polymer. Polypropylene is chosen for its excellent strength, flexibility, and resistance to moisture, making it ideal for packaging perishable items like fruits and vegetables. Leno bag manufacturers use PP granules, which are melted and extruded into fine threads, forming the mesh-like structure that enhances ventilation.
UV Stabilizers for Durability
To improve the longevity of Leno mesh bags, UV stabilizers are added to the polypropylene material during the manufacturing process. These stabilizers protect the bags from degradation caused by prolonged exposure to sunlight, ensuring they remain strong even in outdoor storage conditions.
Color Pigments and Additives
Leno bag manufacturers incorporate color pigments to differentiate bags based on application or branding needs. Common colors include red, yellow, green, and blue. Additionally, anti-static and anti-slip additives are sometimes blended into the material to enhance handling efficiency.
Reinforced Stitching and Drawstrings
Apart from polypropylene, PP leno bags are often reinforced with strong stitching and optional drawstrings. These elements improve the bag’s load-bearing capacity and make it easier to secure and transport bulk produce efficiently
