1. Superior Barrier Performance
This transparent bag in box is crafted with high barrier PE/PA materials, boasting oxygen permeability ≤0.5 cm³/(m²·24 h) and water vapor permeability ≤0.5 g/(m²·24 h). It effectively isolates external oxygen and moisture, preserving the freshness and quality of liquid products like wine, juice and edible oil for an extended period.
2. Durable & Damage-Resistant
Endowed with anti-rubbing and tear-resistant properties, the bag features a tensile strength of ≥20 MPa (vertical/horizontal) and a breakage nominal strain of ≥200%. It is not easily broken or torn during transportation, storage and use, and its soft texture also makes it resistant to kneading.
3. Eco-Friendly & Recyclable
The single-material PE version of the transparent bag in box is made of 100% recyclable food-grade PE, while the PA/PE composite version uses non-toxic food-safe materials. Both options reduce environmental impact and meet global eco-friendly packaging requirements.
4. Flexible Customization
We provide comprehensive customization services, including tailoring the bag's size, thickness and valve type (such as white, red, blue valve options). Logo printing and valve position adjustment are also available to meet the personalized packaging needs of different industries and brands.
5. Leakproof & Easy Dispensing
Equipped with a professional leakproof spout valve, the bag enables smooth and controlled liquid dispensing without splashing. The heat-sealed edges and tight valve sealing design further ensure no liquid leakage during storage, transportation and use.
6. Versatile Industrial 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 a versatile packaging solution for food, beverage, chemical and pharmaceutical industries due to its food-grade safety.
