Chemical White PP Woven Bag

The White PP Woven Bag is an industrial packaging bag made primarily from polypropylene (PP) through a woven process. The white bag is typically used to create a clean, uniform visual effect, making it suitable for industries with high demands on packaging appearance. PP, a thermoplastic, is widely used in packaging due to its excellent processing properties and stable chemical structure. The bag is produced using a warp and weft weaving process, resulting in a bag structure with high strength and toughness. This weaving process, unlike conventional blown film bags, significantly improves the bag's tensile strength and load-bearing capacity.

White PP Woven Bag Features:

1. High Strength:

The White PP Woven Bag is woven from high-density polypropylene flat yarn, achieving a tensile strength of ≥500N/50mm in both warp and weft directions, complying with GB/T 8946-2013. The bag's uniform weave density and stable structure are capable of withstanding a vertical drop test (from a height of 0.8m) under a standard load of 50kg, making it suitable for transporting heavy materials. The reinforced seams connecting the bag bottom and body, with a strength of ≥80N/5cm, effectively prevent cracking during handling. This strength makes the White PP Woven Bag excellent for heavy-load applications such as cement and chemical industries, ensuring safe transportation.

2. Corrosion Resistance:

The PP material used in the White PP Woven Bag exhibits excellent chemical stability and is resistant to corrosion from common acids, alkalis, and salts. After 72 hours of exposure to a chemical environment with a pH of 3-11, the bag's strength retention rate remains at least 95%, meeting the corrosion resistance requirements for chemical packaging materials. The inner layer can be laminated with LDPE film to further block the penetration of corrosive dust or particulate matter. This feature makes the White PP Woven Bag suitable for loading chemical raw materials such as sodium carbonate and ammonium chloride, ensuring long-term packaging stability.

3. Excellent Moisture Resistance:

The White PP Woven Bag's inner layer is laminated with 0.03-0.05mm thick LDPE film, achieving a water vapor transmission rate of ≤5g/m²/24h (38°C, 90% RH), meeting the GB/T 16928-2021 moisture-proof packaging standard. The bottom is heat-sealed with a seal width of ≥10mm, ensuring a reliable seal. After 30 days of storage in an environment with a relative humidity of 95%, the moisture content of the bag contents remains ≤0.5%. This moisture-proof performance ensures the stability of the chemicals contained in the bag in humid environments, making it suitable for storage and transportation in high-humidity regions in southern China.

4. Environmentally Friendly and Degradable:

This White PP Woven Bag incorporates a photo-oxidative and biodegradable masterbatch, complying with the GB/T 38083-2019 standard for biodegradable materials. Under natural sunlight and microbial action, it achieves a degradation rate of ≥30% in 90 days and ≥60% in 180 days. Degradation primarily produces CO₂, H₂O, and biomass, with no harmful residues. This product has passed SGS environmental certification, meeting the modern industry's demand for green packaging and is suitable for use by chemical companies focused on sustainable development.

5. Flexible Customization:

The White PP Woven Bag is fully customizable in size, color, and printing. Finished product dimensions range from 450-910mm in length, 350-600mm in width, and 80-180mm in base width, with a tolerance of ±3mm. It supports one- to four-color printing using a gravure printing process with an overprint accuracy of ≤1mm. Customers can provide designs for logos, warning signs, product information, and other features to create branded packaging. The square base enhances stacking stability and adapts to diverse storage needs.

6. Stable Structure:

The White PP Woven Bag features a square bottom design with a width of 80-180mm, providing a low center of gravity when loaded and allowing stacking up to 3 meters without tipping. The bag's corners are reinforced, and the bottom seams utilize a double-thread chain stitch with a stitch density of 8-10 stitches/3cm. The empty bag exhibits high stiffness, making it easy to bag with automatic filling equipment. This structural design improves storage efficiency, reduces manual intervention, and is suitable for use in automated production lines.

7. Clean Appearance:

The White PP Woven Bag features a white base fabric, resulting in a smooth, impurity-free surface that meets the chemical industry's packaging cleanliness requirements. The white background enhances printing contrast, ensuring clear and eye-catching text and graphics. The production environment complies with ISO 9001 clean management standards, preventing dust and oil contamination. The bag's surface is odorless and does not transfer harmful substances, ensuring the purity of the chemical packaging. This aesthetic enhances brand image and is suitable for export and high-end markets.

8. Cost Optimization:

White PP Woven Bags utilize cost-effective PP raw materials, resulting in unit packaging costs 10%-15% lower than comparable composite bags. Material utilization is ≥95%, and scraps are recyclable. For mass production (≥100,000 bags), the unit price is controlled at 1.8-2.5 yuan per bag, making them economical and durable. Their long service life allows for multiple uses, reducing overall logistics costs. This cost advantage makes them widely applicable for packaging bulk materials such as cement and chemicals.

White PP Woven Bag Applications:
