Product Introduction

PP packaging bags are mainly used to produce woven bags, sewn-bottom open bags, square-bottom valve bags, FFS heavy-duty bags, laminated bags, and square-bottom open bags. They are manufactured using advanced processes such as circular weaving, extrusion coating/lamination, and multi-layer co-extrusion blow molding. Common sizes include 100x150mm and 200x300mm, suitable for small items such as snacks and small accessories; 250x350mm and 350x500mm, suitable for medium-sized items such as books and clothing; and 500x700mm, suitable for large items such as fertilizers, chemical products, and food ingredients.

The core advantage of PP packaging bags lies in their extremely high strength-to-weight ratio, exhibiting excellent tensile strength, puncture resistance, and abrasion resistance, enabling them to withstand repeated handling and stacking of heavy products. Through lamination, it achieves excellent moisture and dust barrier properties, protecting the contents from environmental humidity. The bag is sturdy and durable, with strong UV resistance, making it suitable for short-term outdoor storage. Simultaneously, the bag surface is smooth, offering excellent printing performance for high-definition brand display. It is perfectly compatible with modern FFS fully automated packaging lines, significantly improving packaging efficiency and reducing overall costs.

PP packaging bags are an ideal heavy-duty packaging choice for materials such as chemical granules (e.g., PE, PP, PVC), fertilizers, building materials (e.g., cement, gypsum powder), agricultural feed, grains (e.g., rice, beans), and food ingredients (e.g., sugar, salt). Its diverse bag types and superior performance make it an indispensable industrial packaging carrier for the global chemical, agricultural, building materials, and food industries.
