20L Dairy Bag-in-Box (BIB) with Spout Valve

The 20L dairy Bag-in-Box (BIB) with spout valve is a flexible packaging solution designed for dairy products. The inner bag uses a food-grade multilayer composite film structure, with available materials such as PET/AL/PE, PET/NY/PE, PET/VMPET/PE, PET/PE, PA/PE, PET/AL/NY/PE, kraft paper/PE, and PET/VMPET/NY/PE, in 150–250 µm thickness. The spout valve is the core technical variant of this product, supporting dairy filling, dispensing, and use with bag-in-box systems.

The production process follows gravure printing → lamination → slitting → bag making → heat sealing, with 1–8 color gravure printing available. The product is made in Dongguan, Guangdong, in a 10,000-class clean workshop. Materials are food-grade, and material certificates can be provided upon customer request.

This 20L specification is suitable for dairy packaging, with a minimum order quantity of 10,000 pcs. The factory offers sampling from samples/drawings and supports custom sizes and artwork according to customer requirements, so the BIB inner bag and spout valve configuration can match different dairy packaging needs.

For developing a 20L dairy Bag-in-Box with spout valve, customization can be based on specified composite material, thickness, printing colors, and artwork design. The materials and process focus on food-grade materials, multilayer lamination, and heat-sealed bag making, suitable for customers evaluating and sampling 20L BIB dairy packaging.
