The inner lining of the ton bag is an additional anti-seepage layer inside the ton bag (container bag), usually made of polyethylene (PE) or polypropylene (PP), and used in combination with the external woven bag to form a double-layer protective structure. Common specifications include flat bottomed large openings, reinforcement with tension bars, etc., suitable for the load-bearing requirements of 1-2 tons of materials.

2、 Core functions and advantages

Moisture proof and Leak proof: The inner membrane adopts waterproof materials (such as PE) heat sealing technology, effectively isolating moisture, dust, and liquid leakage. It is suitable for chemical powders, fertilizers, and other materials that are prone to moisture.

Durability: Thick inner lining (such as 6 or more threads) paired with high-strength woven bags, resistant to forklift handling and high-frequency turnover.

Economic flexibility:

Second hand inner membrane ton bags can be refurbished through high-pressure cleaning, reducing packaging costs for enterprises.

Support size customization (such as 30cm × 40cm to 120cm × 150cm) to meet the needs of different industries.

3、 Typical application scenarios

Chemical industry: Sealed transportation of raw materials with high moisture-proof requirements such as granular resin and industrial salt.

Agriculture and Environmental Protection: Anti swelling packaging for bulk materials such as fertilizers and sludge to reduce transportation pollution.

Pre pressing of building materials: moisture-proof storage and turnover of sand and cement in bridge engineering
