This product is a 3L Bag-in-Box (BIB) for egg liquid, featuring an aseptic cap structure as its core technical variant. It is intended for flexible packaging applications involving egg liquid. Compared with same-size, same-use BIB products with different cap types or dispensing structures, the aseptic cap variant serves as a clear differentiation point for targeted selection in egg liquid packaging scenarios.
The bag can be made from common composite 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, with a thickness range of 15–25 silk units (multi-layer composite). The specific material structure can be selected according to the customer's packaging contents, capacity, dispensing method, and artwork requirements. Food-grade materials are used, and material certificates can be provided upon customer request.
The production process is gravure printing → lamination → slitting → bag making → heat sealing, with 1–8 color gravure printing available. The place of origin is Dongguan, Guangdong, and the production workshop is a 10,000-class cleanroom. The minimum order quantity is 10,000 pieces. The factory offers sample/drawing proofing services and can customize sizes and artwork according to customer requirements.
During customization, proofing and confirmation are carried out around the 3L specification, egg liquid application, and aseptic cap structure. After evaluating the selected composite material, printed artwork, bag dimensions, and heat-sealing process, the product can proceed to batch production. This product is suitable for Bag-in-Box packaging needs involving egg liquid, with clear emphasis on the combination of 3L size, egg liquid use, and aseptic cap technical variant.
