The 3L red wine Bag-in-Box (BIB) with button valve is a flexible packaging solution designed for 3L red wine packaging and dispensing. The button valve is the core dispensing component of this product, distinguishing it from same-specification, same-application options with ordinary valves or valveless bag types, and it helps support controlled dispensing. The bag body uses food-grade multilayer laminated materials, 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 range of 15–25 silk (multilayer lamination), selectable according to red wine packaging requirements.
In terms of materials and specifications, the product is based on food-grade materials, and material certificates can be provided upon customer request. Common laminated materials can be selected according to content, transportation, and presentation needs, with thickness controlled at 15–25 silk (multilayer lamination). The 3L capacity is suitable for red wine bag-in-box applications, and the button valve supports dispensing control, making it suitable for red wine packaging scenarios that require both packaging protection and ease of use.
The production process is gravure printing → lamination → slitting → bag making → heat sealing, with printing supporting 1–8 color gravure printing. Production is located in Dongguan, Guangdong, in a 10,000-class cleanroom. The MOQ is 10,000 pieces, suitable for red wine bag-in-box packaging projects requiring stable batch supply.
The factory can provide sample-based or artwork-based proofing, and customize dimensions and layouts according to customer requirements. Whether adjusting bag specifications, printed layouts, or selecting different multilayer laminated materials, customization can be centered on the 3L red wine Bag-in-Box with button valve. The product is suitable for red wine liquid packaging, and food-grade material certificates can be provided upon customer request.
