51-20L Liquid BIB Bag-in-Box | Aluminum Foil Clear Laminate Pouch for Cooking Oil, Egg White & Soup

Built for bulk liquid food handling, this 20L-class bag-in-box pouch suits cooking oil, egg white, soup and similar liquids during filling, transfer and storage. It works with a cardboard outer carton; once filled and sealed, the inner pouch stays closed through shipping and warehousing. A valve selected for the liquid's viscosity lets users dispense without opening the full bag.

The laminate brings together aluminum foil, pure aluminum and transparent film. Foil blocks light and oxygen, pure aluminum strengthens the moisture barrier, and the clear window helps monitor fill level. Finished pouches feel structured rather than rigid; edge seals remain intact after repeated folding, making them suitable for long-haul transport after filling.

Branding can be printed in 1–8 colours. Capacities run from 1–200 L, with pouch length and fitment sized to the filling line. Accessory options include butterfly valves, tap valves, oil valves, pointed-spout valves and the outer carton. Minimum order quantity is 10,000 pcs.

Primary applications include cooking oil, egg white and liquid soup, while the same format also serves bulk sauces and beverages. Relevant search terms include BIB bags, bag-in-box, valve pouches, liquid bags, sauce bags and juice drink bags, reflecting broad compatibility across food and beverage supply chains.

Kody Packaging performs lamination and pouch conversion in Dongguan, Guangdong. Before dispatch, we verify seal strength and valve tightness, and can produce samples from a customer's reference pouch or drawing. Because material and accessory combinations vary by order, final pricing follows sample approval and confirmed quantity. Pouch length, fitment diameter and carton dimensions are also confirmed together.
