20L bag-in-box for red wine featuring a butterfly dispensing valve, made from food-grade multilayer laminated film with 1–8 color gravure printing in a Class 10,000 clean workshop in Dongguan, with sample- and artwork-based customization.
This is a 20L bag-in-box (BIB) designed for red wine, and its core technical variant is the butterfly valve dispensing fitment, heat-sealed to the bag body to enable controlled pouring and resealing inside the outer carton, distinguishing it from same-size, same-application BIB products with other valve or dispensing structures.
Common laminate structures include 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, selected according to the oxygen-barrier, light-blocking and mechanical-strength requirements of red wine; the multilayer film thickness is 15–25 silk.
Printing is 1–8 color gravure, carrying brand artwork and product information; the process runs gravure printing → lamination → slitting → bag making → heat sealing, with the butterfly valve assembled during bag making and heat sealing, all performed in a Class 10,000 clean workshop.
The product serves red wine packaging, and the 20L format fits the bag-in-box filling format for food service, events and distribution; materials are food-grade and material certificates can be provided upon customer request.
Customization: customers provide samples or artwork, and the factory supports custom sizes and artwork per customer requirements, with a minimum order quantity of 10,000 pieces, produced in Dongguan, Guangdong.
