Square Bottom Valve Bags are a high-demand product in the packaging industry due to their durability, flexibility, and reliability in various applications. These bags are ideal for packaging granular materials, powders, and other bulk products across different sectors.
Characteristics of Square Bottom Valve Bags
Square Bottom Valve Bags, also referred to as Square Bottom Valve Sacks, Square Bottom Woven Bags, and Valve PP Bags, are crafted from polypropylene (PP) to provide several beneficial features:
- Enhanced Stability and Stackability
The square bottom design allows for better stability, making these bags easy to stack. Unlike traditional woven bags, which tend to sag, Square Bottom Valve Bags retain their form, thus enhancing warehouse space efficiency and minimizing the risk of tipping over. - Strength and Durability
Made from high-quality PP materials, Square Bottom Valve Bags exhibit exceptional tensile strength. They are suitable for handling heavy and coarse materials without tearing or bursting. With a dense woven structure, they are highly resilient against mechanical stress, providing reliable performance during transport and storage. - Moisture Resistance
These bags are often laminated or coated, providing resistance to moisture, ensuring the protection of the contents from environmental factors. The moisture barrier is critical for products sensitive to humidity, such as cement, chemicals, and food-grade products. - Easy Filling and Sealing
Featuring a valve opening, these bags simplify filling and sealing, speeding up the packaging process. The valve automatically closes once the bag is filled, preventing spillage or leakage, which reduces packaging costs. - Customization Options
VidePak offers Square Bottom PP Bags with various customization options, including multicolor printing for branding, different sizes to suit specific needs, and additional features like perforations for breathability.

Quality Control in Raw Material Selection and Management
To ensure the highest standards in Square Bottom Valve Bags, strict quality control measures are implemented at every stage, from raw material procurement to storage.
1. Procurement of High-Quality Raw Materials
VidePak sources high-quality raw materials to ensure the structural integrity and reliability of Square Bottom PP Bags. The primary materials include new polyethylene (PE) and polypropylene (PP) granules, which provide the necessary flexibility and strength for our bags.
- Supplier Selection and Vetting
VidePak selects suppliers based on their track record, compliance with environmental standards, and production consistency. The company conducts regular audits to verify supplier adherence to stringent quality standards. - Batch Testing of Raw Materials
To maintain consistent quality, raw materials are tested in batches upon arrival. These tests include analyzing mechanical properties such as tensile strength, elongation, and impact resistance. - Specific Material Requirements
The specifications for materials used in Valve PP Bags require granules with low melting points for ease of processing while maintaining durability.
2. Warehouse Storage and Handling
Proper storage and handling of raw materials are essential to prevent contamination or degradation. VidePak’s facilities follow strict protocols to preserve material quality throughout the production cycle.
- Temperature and Humidity Control
Storage areas are climate-controlled to maintain stable temperature and humidity levels. Excessive heat can cause materials like PP to lose flexibility, impacting the final product’s performance. - Batch Segregation
Each batch of raw materials is labeled and stored separately to track their quality over time. This system allows for better traceability and enables prompt action if an issue arises in a particular batch. - Regular Inspections
Routine inspections are conducted to identify any signs of degradation or contamination, which could compromise the quality of Square Bottom Woven Bags.
