|---|---|---|
| Seeds (Wheat, Corn) | 90-120 | 25-50 kg |
| Nuts (Almonds, Cashews) | 70-100 | 10-25 kg |
| Rice and Grains | 80-110 | 25-50 kg |
| Coffee Beans | 80-100 | 15-30 kg |
| Starch and Flour | 60-80 | 10-25 kg |
3. Bag Size
PP Woven Bags can be customized in terms of size to suit different product volumes. The size of the bag must balance between holding a sufficient volume of product and being manageable for transportation and storage. Larger bags (50 kg capacity) are often used for bulk products like grains and rice, while smaller bags are more common for higher-value products like nuts or coffee beans, where protecting the integrity of the product is critical.
| Product | Typical Bag Size | Volume |
|---|---|---|
| Rice, Soybeans, and Corn | 50 x 80 cm | 50 kg |
| Coffee Beans | 40 x 60 cm | 25-30 kg |
| Wheat and Barley | 50 x 80 cm | 50 kg |
| Nuts (Almonds, Cashews) | 40 x 60 cm | 15-25 kg |
| Starch and Flour | 40 x 60 cm | 10-25 kg |
Customization Options for Woven Recyclable Bags
One of the most significant benefits of Woven Recyclable Bags is their versatility and customizability. Customers can choose from several customization options based on the specific needs of the product they are packaging.
1. Lamination
Lamination is an essential option for certain agricultural products that are sensitive to moisture or external contaminants. A laminated bag is coated with a thin layer of polyethylene (PE) or another material to make it water-resistant.
- Laminated Woven Recyclable Bags are ideal for products like rice, soybeans, and coffee beans, which require additional protection from humidity to maintain freshness and quality.
- For products that need breathable packaging, such as certain types of grains or nuts, non-laminated bags may be preferred. These bags allow for better air circulation, reducing the risk of mold or spoilage.
2. Inner Liners
An inner liner can be added to Woven Recyclable sacks to offer extra protection, particularly for moisture-sensitive products such as starch or flour. The liner is usually made of a thin PE film, providing an additional barrier against moisture while also preventing contamination from external elements.
- Products like starch, flour, and processed grains often benefit from inner liners due to their high moisture sensitivity.
- Grains and nuts, which are less moisture-sensitive but still require some protection, may use either laminated bags or bags with inner liners depending on transportation and storage conditions.
3. Sealing Methods
The way a bag is sealed also plays a critical role in ensuring the product remains fresh during transport and storage. Options include heat sealing, stitching, or using valve bags that allow for quick and easy filling and sealing.
- Heat Sealing: Provides an airtight closure, ideal for moisture-sensitive products like coffee beans and starch.
- Stitched Closure: Typically used for larger bags that hold products like grains or seeds, providing a strong and durable seal.
