This 5 L liner bag is specified for smoothie base applications where oxygen and light exposure can dull color and flavor. The film structure is built around a food-contact grade PET/AL/PE or PET/VMPET/PE laminate, with the aluminum or metallized layer selected for oxygen and light barrier, the PE sealant chosen for fitment integrity and product compatibility, and the overall combination reviewed against shelf-life goals. The liner is designed for bag-in-box systems, with a center spout and dispensing fitment that supports clean emptying in beverage and dairy operations. It can be supplied for aseptic filling lines, with fitment and film combinations reviewed against the filler, product pH, and processing conditions before sampling.
Printing is available by 10-color rotogravure, allowing brand, lot, and handling information to be placed on the liner or supplied in plain form for downstream labeling. We discuss artwork, repeat length, fitment position, and roll orientation before plates are made; digital or physical proofs can be arranged as part of sampling. Standard MOQ is 10,000 liner bags per size and print combination, with lower quantities considered for plain stock or trial orders. Sampling typically moves from film and fitment confirmation to filled-line trials, so beverage and dairy producers can check seal quality, dispensing, and box fit before production.
Manufactured in our Dongguan clean workshop, the liner bag runs on spout-insertion and pouch-making equipment suited to 5 L and custom capacities. For US West Coast buyers, we quote lead time after artwork, fitment, and film approval, typically within 15–25 working days for repeat orders and longer for new rotogravure plates. We can support bag-in-box dispensing concepts for cold-brew concentrate, juice, cream, kombucha, plant milk, and smoothie bases while keeping the specification factual to the approved film and fitment. Please share fill volume, filler type, cap or valve preference, and expected distribution conditions so we can recommend the right liner construction and sampling plan.
