3L Dairy Bag-in-Box (BIB) with Button Valve

The 3L dairy bag-in-box (BIB) with button valve is designed for dairy packaging. The bag body uses multilayer composite films, with common structures including 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, with a thickness of 15–25 silk; suitable composite structures can be selected according to dairy packaging requirements.

The production process is gravure printing → lamination → slitting → bag making → heat sealing. Printing supports 1–8 color gravure printing and can be customized for dairy packaging layouts. The 3L specification and button valve configuration are the core identifying features, distinguishing it from same-size, same-use bag-in-box products with different valve types.

The product is made in Dongguan, Guangdong, in a 10,000-class cleanroom using food-grade materials; material certificates are available on request. The MOQ is 10,000 pcs, suitable for dairy bag-in-box sourcing needs with clearly defined specifications, application, and valve configuration.

The factory offers sample/image proofing and supports custom sizes and layouts on request. For 3L dairy bag-in-box with button valve applications, customization can be discussed around multilayer composite film structures, printing colors, and layout solutions.
