Woven Bag
Woven Bag
PP woven bags, also known as polypropylene woven bags, are made from polypropylene as the main raw material. They are extruded and stretched into flat strands, and then processed through weaving, printing, cutting, and sewing to form packaging containers.
They have excellent flexibility and impact resistance, and can stably protect the internal items in various environments. With the characteristics of being lightweight, durable, and cost-effective, they have become the preferred choice for packaging in many industries.
Whether it is granular, powdered, or block-shaped items, they can be safely and conveniently stored and transported through PP woven bags. At the same time, their recyclable and reusable feature also aligns with the current green development concept.
Woven Bag
Advantages
High-strength and durable
Made from high-quality polypropylene raw materials and processed through special techniques, it has excellent tensile strength and tear resistance, can withstand the weight of heavy items, and is less likely to be damaged during transportation and handling, effectively ensuring the safety of the items.
Excellent weather resistance
It has good performance in withstanding high and low temperatures, with minimal changes in physical properties, and can adapt to different climate environments in different regions. Whether in hot southern regions or cold northern regions, it can be used normally.
Waterproof and moisture-proof
Some PP woven bags are treated with coating, forming an effective barrier against moisture and water intrusion, preventing the internal items from getting damp and deteriorating. Especially suitable for packaging products with high requirements for moisture protection, such as grains and chemical raw materials.
Light and easy to carry
Compared to traditional wooden or iron packaging, PP woven bags are lightweight and small in size, making them easy to load, handle, and store, which can reduce transportation costs and labor intensity, and improve work efficiency.
High customization degree
According to different customer needs, it can be personalized in terms of color, size, thickness, and printed patterns, meeting the brand promotion and diverse packaging needs of customers.
Environmentally friendly and recyclable
The main raw material of PP woven bags, polypropylene, can be recycled and reused. After being discarded, it can be properly treated to reduce environmental pollution and comply with national environmental protection policies and sustainable development requirements.

Shopping bags / Eco-friendly bags
Thick PP woven bags with printed patterns are used as shopping bags. They are more durable than ordinary plastic bags and can be reused.
Moving and Storage
With large capacity and strong load-bearing capacity, it is perfect for packing clothes, books, bedding and other items. It is an excellent helper for moving and home storage.
Logistics and express delivery
For some light and fragile goods that are not afraid of being crushed and have large volumes (such as textiles, toys, and plastic products), the express delivery industry uses woven bags for packaging.
Temporary covering
During outdoor activities, it can be used temporarily to cover items that are afraid of getting wet; farmers use it to cover crops or haystacks.
PP woven shopping bags are often used as a big shopper for groceries or as promotional material at a trade fair or other event. The strong PP woven material ensures that the bag will be reused often. The shoppers are provided with soft webbing loops or loops made of PP woven material.
For the printing of the PP woven shopping bags, you can choose from different quality materials. If you are using small-sized shoppers or if the bag is used for light products, a thickness of 120 grams PP woven is sufficient. The large format shoppers, as you see them in the supermarket, are usually made of 160 grams PP woven. 140 grams PP woven is the middle way. The PP woven material is finished with a gloss or matt laminate. PP woven shopping bags have a woven structure on the inside. With RPET shopping bags, the material feels a lot softer.

Woven Polypropylene Manufacturing Process
The manufacturing process of woven polypropylene reusable bags involves several steps. Here's the process:
Material Selection: Polypropylene (PP) resin is the primary raw material for woven polypropylene bags. The resin may contain additives to enhance specific properties like UV resistance or color.
Extrusion: The polypropylene resin is melted and extruded through a circular die to create flat plastic tapes. These tapes are then stretched and cooled to form a flat ribbon-like structure.
Warping: The flat tapes are wound onto spools and arranged parallel to each other. These tapes will become the warp (lengthwise) threads of the woven fabric.
Weaving: The warp tapes are interlaced with weft (crosswise) tapes using a weaving machine. The weaving process creates a woven fabric with a unique pattern and texture.
Lamination (Optional): In some cases, the woven fabric may undergo a lamination process to enhance strength, water resistance, or printability. A layer of polypropylene film may be added to one or both sides of the custom laminated bag fabric.
Printing (Optional): If desired, the woven fabric can be printed with various designs, logos, or information. This step typically occurs after lamination.
