1. High Barrier Performance
This transparent bag in box is made of food-grade PA/PE or high barrier PE material, with oxygen permeability as low as ≤0.5 cm³/(m²·24 h) and water vapor permeability ≤0.5 g/(m²·24 h). It effectively blocks oxygen and moisture from entering, ensuring the freshness and quality of liquid products such as beverages and edible oil for a long time.

2. Durable & Anti-damage
Featured with anti-rubbing property and high tensile strength (vertical/horizontal ≥20 MPa for PE material), the bag is not easy to break or tear during transportation and use. Its soft texture also makes it resistant to kneading, adapting to various storage and handling scenarios without easy damage.

3. Eco-friendly & Recyclable
The single-material PE version of the transparent bag in box is 100% recyclable, which conforms to environmental protection requirements. Even the composite PA/PE structure is made of food-grade non-toxic materials, reducing environmental pollution while ensuring the safety of packaged liquid products.

4. Customizable Design
We offer comprehensive customization services for the bag, including size, thickness, valve type (such as white, blue, green valve options) and valve position adjustment.

5. Easy Dispensing & Leakproof
Equipped with a professional spout valve, the bag enables smooth and controlled dispensing of liquids without splashing. The tight sealing design of the valve and the heat-sealed edges of the bag ensure excellent leakproof performance, avoiding liquid leakage during storage and use.

6. Versatile Application
Suitable for packaging a wide range of liquid products, including water, milk beverages, fruit jam, wine, edible oil, engine oil and daily chemical products. It is an ideal packaging solution for food, beverage, chemical and other industries due to its food-grade safety and excellent barrier performance.
