When it comes to industrial packaging solutions, Sewn Open Mouth Bags (SOM Bags) have gained significant popularity for their durability, versatility, and ability to secure a wide range of products. These bags are commonly used in packaging for various industries such as chemicals, agriculture, food products, and construction materials. The strength of these bags lies in their design, material, and production process, making them an ideal choice for both heavy-duty and lightweight packaging applications.
Sewn Open Mouth Bags, also referred to as Sewn Open Mouth Sacks or Open Mouth Bags, are designed to ensure that products are safely enclosed, whether for long-term storage or transportation. Their open-top design allows easy filling, while the sewn closure ensures that the contents are sealed securely. Understanding the manufacturing processes and the stringent quality control mechanisms behind these bags is essential to ensuring their reliability. This is especially true when it comes to the raw materials used in their production — namely, PP (polypropylene) and PE (polyethylene) plastic granules.
Material Quality and Its Role in Bag Durability
Before diving into the specifics of Sewn Open Mouth Bags and their use, it’s critical to highlight the importance of the materials used in their production. Polypropylene (PP) is the primary material used for these bags, and its quality is fundamental to the bag’s performance. PP granules are highly versatile and offer a range of desirable qualities, including resistance to wear, tear, and environmental stress. The material also possesses significant chemical resistance, making it suitable for packaging various products, including chemicals, grains, and fertilizers.
At VidePak, our commitment to quality starts with sourcing the best PP and PE plastic granules. These materials undergo rigorous testing to ensure they meet high standards before being used in the production process. Below are key parameters that are tested for each batch of PP and PE granules used in manufacturing:
| Test Parameter | Description |
|---|---|
| Appearance | Granules are visually inspected for any discoloration, contamination, or inconsistencies. |
| Melt Flow Index (MFI) | Measures the ease with which the granules can be molded, indicating material flow characteristics. |
| Density | Determines the material’s density, ensuring that it meets specific product weight requirements. |
| Tensile Strength | Tests the force required to stretch the material before it breaks, ensuring durability under stress. |
| Elongation at Break | Measures how much the material can stretch before breaking, indicating flexibility and resistance. |
| Thermal Stability | Ensures the material can withstand high temperatures without degrading. |
| Chemical Resistance | Assesses the granules’ resistance to common chemicals that may be encountered during use. |
| UV Resistance | Tests the material’s ability to withstand ultraviolet (UV) light exposure without degradation. |
This quality testing ensures that only the highest quality materials are used in the production of Sewn Open Mouth Bags.
Production Process and the Role of Equipment
After the raw materials pass quality checks, the next step is the production process. At VidePak, we employ advanced machinery, including Starlinger equipment, which is known for its precision and efficiency. The use of circular looms and extrusion lines guarantees that the bags produced are of the highest quality and meet international standards. The Sewn Open Mouth Bags are woven to a specific tightness and strength that makes them ideal for handling and transporting heavy goods.
A key feature of our production is the use of a multi-layered extrusion process, which helps ensure the bags are tear-resistant and provide additional strength. The bags’ construction is critical, especially when they are used for heavy-duty applications such as bulk grain or construction materials. The multi-layer construction provides added durability and protection against punctures or tears during handling and transportation.
Additionally, the lamination process plays an important role in the overall strength of the bags. Laminated bags offer enhanced moisture resistance and can withstand rough handling without compromising the contents. Whether you are using Sewn Open Mouth Bags for fertilizers or Block Bottom Bags for bulk construction materials, the laminated finish ensures better protection for your goods.
Applications of Sewn Open Mouth Bags
The versatility of Sewn Open Mouth Bags extends to a wide range of applications. Here are a few common areas where these bags are used:
- Agriculture: For packing seeds, fertilizers, and other agricultural products, Sewn Open Mouth Sacks provide a cost-effective solution that can be customized in terms of size, strength, and material.
- Construction: Open Mouth Bags are used to carry construction materials such as cement, sand, and gravel. The strong PP material can hold heavy loads and is resistant to tears, even in harsh weather conditions.
- Food Products: Sewn Open Mouth Bags are used in the food industry for packaging grains, sugar, and flour. Their breathability ensures that food products remain dry and fresh during storage.
- Chemicals and Fertilizers: In industries dealing with chemicals or fertilizers, these bags provide an excellent solution due to their resistance to chemicals and moisture. The bags can be sealed tightly to prevent any leakage.
