Standard PP woven bags are a simple, durable, and cost-effective packaging solution for a wide range of dry products. Made from woven polypropylene (PP) fabric, these bags provide good strength and flexibility for packaging, transportation, and storage.
They are widely used for fertilizers, animal feed, rice, grains, seeds, minerals, chemicals, and construction materials.
What Are Standard PP Woven Bags?
Standard PP woven bags are packaging bags made from woven polypropylene fabric.
During production, polypropylene resin is extruded into flat tapes. These tapes are then woven together to create a strong PP fabric. The fabric is cut and sewn into bags according to the required size and capacity.
The basic structure is simple:
PP Resin → PP Tapes → Woven Fabric → Cutting → Sewing → Finished PP Woven Bag
Basic Structure
| Part | Material | Function |
|---|---|---|
| Main fabric | Woven polypropylene | Provides strength and durability |
| Sewing thread | PP or other suitable thread | Connects bag panels |
| Printing | Ink | Displays product and company information |
| Bag opening | Woven PP fabric | Used for filling products |
| Bottom | Sewn PP fabric | Supports the packaged product |
Standard PP woven bags normally have a straightforward construction, making them suitable for large-volume packaging where basic strength and functionality are the main requirements.
Key Benefits of Standard PP Woven Bags
1. Good Strength
The woven polypropylene structure provides good tensile strength and resistance to tearing.
This allows the bags to withstand normal handling during filling, transportation, loading, unloading, and stacking.
2. Lightweight
PP is a lightweight material, so woven PP bags can provide good packaging performance without adding excessive packaging weight.
3. Cost-Effective
Standard PP woven bags have a relatively simple structure and production process.
This makes them an economical option for businesses that purchase packaging bags in large quantities.
4. Flexible
PP woven fabric is flexible and can accommodate different product volumes.
The bags can also be manufactured in different sizes, fabric weights, colors, and capacities.
5. Easy to Customize
Standard PP woven bags can be customized according to product and customer requirements.
| Customization | Options |
| Bag size | Customized |
| Capacity | Customized |
| Fabric weight | Customized |
| Bag color | White or customized |
| Printing | Customized |
| Sewing | Different sewing methods |
| Packaging | Bundles, pallets, or customized |

Standard PP Woven Bags for Fertilizer
Fertilizer is one of the common applications for PP woven bags.
They can be used for products such as:
- NPK fertilizer
- Compound fertilizer
- Urea
- Agricultural fertilizer
- Granular fertilizer
For fertilizer packaging, the bag size and fabric weight should be selected according to the product weight, density, filling process, and transportation conditions.
Standard PP Woven Bags for Animal Feed
PP woven bags are also commonly used for animal feed packaging.
| Feed Type | Common Packaging |
| Poultry feed | PP woven bags |
| Livestock feed | PP woven bags |
| Fish feed | PP woven bags |
| Feed additives | PP woven bags |
| Agricultural feed products | PP woven bags |
The bags can be printed with product information, company logos, handling instructions, and other branding elements.
Standard PP Woven Bags for Rice and Grains
PP woven bags are suitable for packaging many agricultural products, including:
- Rice
- Wheat
- Corn
- Seeds
- Other grains
The appropriate bag size depends on the product density and required filling weight.
For example, a 25 kg rice bag may require different dimensions from a 50 kg grain bag.
Standard PP Woven Bags for Industrial Products
Standard PP woven bags are also used for many industrial materials.
Common products include:
- Calcium carbonate
- Gypsum powder
- Sand
- Dry chemicals
- Industrial minerals
- Construction materials
For heavier products, the fabric weight and sewing construction should be selected according to the required load-bearing performance.
How to Choose the Right PP Woven Bag
Selecting the correct PP woven bag starts with understanding the product and packaging process.
| Factor | What to Consider |
| Product | Powder, granule, grain, fertilizer, feed, etc. |
| Product weight | Required filling capacity |
| Product density | Determines bag volume and dimensions |
| Bag size | Must match product volume |
| Fabric weight | Affects strength and durability |
| Filling method | Manual or automatic filling |
| Transportation | Handling, stacking, and shipping conditions |
| Printing | Product information and branding |
| Quantity | Affects production and pricing |
1. Product Type
Different products have different packaging requirements.
Granular products such as fertilizer and grains can generally be packaged in standard woven bags, while fine powders may require additional consideration of containment and bag construction.
2. Bag Capacity
The capacity should match the customer’s required filling weight.
Common options include:
25 kg | 40 kg | 50 kg
Custom capacities are also available.
3. Fabric Weight
Fabric weight is an important factor affecting bag strength.
For example, a bag designed for 25 kg products may use a different fabric specification from a bag designed for 50 kg products.
The final specification should be determined according to the product weight and handling conditions.
4. Bag Dimensions
Bag dimensions should match the product volume rather than only the filling weight.
Products with different densities may require different bag dimensions even when they have the same filling weight.
5. Printing
Standard PP woven bags can be printed with basic product and company information.
Typical printing content includes:
- Company logo
- Product name
- Product weight
- Product information
- Handling instructions
- Contact information
