When it comes to packaging solutions, Open Mouth Bags play an essential role in various industries. From agricultural products to industrial materials, these bags offer flexibility, durability, and customization to meet specific needs. This article will delve into the manufacturing process of Open Mouth PP Bags, focusing on the importance of material quality control and how companies like VidePak ensure top-notch products.
The Versatility of Open Mouth Sacks
Open Mouth Sacks, a key form of woven polypropylene (PP) bags, are popular for their simple yet highly effective design. These bags are commonly used in packaging a wide range of products, including grains, fertilizers, and pet food. The design of Open Mouth Bags is quite versatile, with variations like Sewn Open Mouth Bags and Block Bottom Bags catering to different functional needs. The ultimate advantage of these sacks is their ability to be easily filled and sealed, offering efficient and secure storage for bulk items.

Understanding the Role of Raw Materials in Manufacturing
The foundation of any quality packaging product lies in its raw materials. For Open Mouth PP Bags, the materials used must be of the highest standard to ensure durability, strength, and reliability. VidePak sources its PP and PE pellets from renowned producers like SINOPEC, CNPC, YPC, and Hengli Group. These suppliers are leaders in the plastics industry, known for their commitment to quality. By only using new PP and PE plastic pellets, VidePak ensures that every bag is made from high-quality, virgin materials rather than recycled ones, which could compromise performance.
Quality Control at Every Step
To guarantee the highest standards of product quality, VidePak implements a rigorous quality control process, beginning with the procurement of raw materials. The company conducts strict batch testing on incoming materials to meet international standards. The raw materials undergo a series of tests, including tensile strength tests, melt flow index tests, and impurity screenings. This process ensures that each batch of PP and PE pellets meets the required specifications before they are used in production.
| Parameter | Test Method | Standard |
|---|---|---|
| Tensile Strength | ASTM D638 | ≥25 MPa |
| Melt Flow Index | ASTM D1238 | 10-30 g/10 min |
| Moisture Content | ISO 15512 | ≤0.5% |
| Color Consistency | Visual Inspection | Consistent, no spots |
| Impurity Screening | Microscopy and filtration | ≤0.05% |
The Open Mouth Bags manufacturing process involves high-tech machinery and skilled labor. VidePak uses equipment from top-tier suppliers like Starlinger to produce woven bags with precise specifications. The process includes weaving, laminating, printing, and finally sewing the bags. Each step is monitored to ensure consistent quality across all products.
Why Use Only New PP and PE Pellets?
The choice of using only new PP and PE pellets has significant advantages. These materials provide superior strength, better printability, and enhanced durability compared to recycled plastic. Additionally, they offer better resistance to moisture and environmental conditions, ensuring the integrity of the contents inside the Open Mouth Bags. For industries requiring high-performance packaging, this quality makes a tangible difference in product safety and shelf life.

The Role of Block Bottom Bags in Specialized Packaging
Block Bottom Bags are another variant of Open Mouth Bags, designed for improved stacking and handling. These bags are engineered to stand upright, thanks to their structured base. This makes them ideal for bulk products that need to be stored and transported efficiently. Whether used in the agricultural sector or for heavy-duty industrial materials, Block Bottom Bags ensure better use of space in warehouses and transportation.
Meeting International Standards
VidePak’s commitment to quality is further demonstrated through its adherence to international standards such as ISO 9001 for quality management systems and ISO 14001 for environmental management. By maintaining high standards in both manufacturing and environmental impact, VidePak ensures that its Open Mouth Bags and other woven products meet the needs of global markets. From the material sourcing stage to the finished product, every step is designed to align with industry regulations and meet customer expectations.
Conclusion: The Importance of Quality Control
The ultimate performance of Open Mouth Bags depends not only on the design but also on the materials and quality control processes in place. By partnering with top-tier suppliers like SINOPEC, CNPC, YPC, and Hengli Group, and employing strict quality control measures, VidePak ensures that each bag is of the highest quality. Whether for agricultural, industrial, or commercial use, VidePak’s Sewn Open Mouth Bags, Block Bottom Bags, and other woven packaging solutions offer unmatched reliability, durability, and performance.
