20L Heavy-Duty Transparent Bag-in-Box for Olive Oil and Juice

This 20L bag-in-box is built for large-volume liquid packaging. The transparent bag lets operators check remaining content at a glance once it is placed inside a corrugated box. Four-side heat sealing keeps the bag firm and resistant to collapsing, while the top can be fitted with a spout or butterfly valve for smooth, controlled dispensing. Combined with the outer box, it handles stacking, drop and pressure demands in retail, food service and filling line use.

The bag body is made from food-grade PE and multilayer laminated film, with an inner layer suitable for direct contact with edible liquids and an outer layer available in clear or matte finish. We support 1-8 colour gravure printing for brand marks, volume scales and usage instructions. Bag style, spout diameter and film width can be adjusted, with capacities such as 5L, 10L and 20L, and matching roll film in the same material is available. Customisation by sample or artwork is welcome.

These bags are widely used for edible oil, syrup, juice, concentrate and sauce packaging and transfer, as well as liquid dispensing in food service chains, food processing and household chemical lines. Custom orders start with confirming bag type, capacity and outlet style, followed by sampling, printing and bulk production. Our factory is located in Dongguan, Guangdong, with a Class 10,000 cleanroom and an MOQ of 10,000 pcs, and we work with export packing requirements.
