Sewn open mouth bags, also known as open mouth sacks or block bottom bags, are widely used in various industries due to their durability and functionality. These bags are designed for easy filling and are suitable for a range of applications, from agriculture to construction. To ensure the highest quality and production efficiency, our company utilizes a comprehensive set of equipment from the globally recognized supplier Starlinger. This article will delve into the features of sewn open mouth bags, the production process, and how advanced technology contributes to superior product quality.
1. Overview of Sewn Open Mouth PP Bags
Sewn open mouth bags are crafted from woven polypropylene, making them robust and versatile. Their design includes a wide opening at the top, allowing for easy filling, which is particularly beneficial in high-volume environments.
Key Features of Sewn Open Mouth Bags:
- Durability: Constructed from high-strength materials, these bags can withstand heavy loads and rough handling.
- Versatile Applications: Ideal for various products, including grains, animal feed, fertilizers, and construction materials.
- Customization: Available in different sizes, colors, and printing options to meet specific branding and operational needs.
2. Importance of Quality in Sewn Open Mouth Bags
Quality is paramount when it comes to packaging. Sewn open mouth bags must meet specific performance criteria to ensure that they protect the contents effectively and withstand the rigors of transport and storage. Here are some key quality aspects:
2.1 Structural Integrity
The bags must maintain their shape and strength even when filled to capacity. Any weakness in the seams or material can lead to failures, resulting in product loss.
2.2 Moisture Resistance
For many applications, moisture can be a significant threat. Ensuring that the bags provide adequate protection against humidity and moisture is crucial for maintaining product quality.
2.3 Aesthetic Appeal
In many industries, the appearance of the packaging plays a role in marketability. Consistent color and branding help to establish a strong brand identity.
3. The Production Process of Sewn Open Mouth Bags
To achieve the high-quality standards required for sewn open mouth bags, our production process is meticulously designed and implemented using advanced technology from Starlinger. Here’s a breakdown of the main production steps:
3.1 Extrusion
The process begins with the extrusion of polypropylene resin into film. This step is critical as the quality of the film will directly affect the final product.
3.2 Circular Weaving
The extruded film is then woven into fabric using circular looms. This process creates a strong, durable material suitable for bag production. The use of advanced circular looms ensures uniformity and consistency in the fabric.
3.3 Printing
Once the fabric is woven, it may undergo printing. This step allows for branding and product information to be displayed on the bags. High-quality printing technology ensures that colors are vibrant and consistent.
3.4 Coating and Laminating
To enhance the properties of the bags, they may be coated or laminated. This provides additional moisture resistance and can also improve UV protection, making the bags suitable for outdoor storage.
3.5 Sewing and Finishing
Finally, the bags are cut to size and sewn closed at the bottom. This sewing process ensures that the bags are securely sealed and ready for filling.
4. Comprehensive Equipment from Starlinger
