These 1–5 l vacuum pouches are built for sauerkraut brine in German and EU food operations, where salt, acidity and liquid handling demand a robust package. The standard high-barrier structure is PET/AL/PE, combining printability, aluminium barrier and a thick PE food-contact sealing layer; PE-heavy or mono-PE recyclable options can be reviewed where shelf-life and barrier targets allow. Wide heat-seal edges and controlled headspace help support reliable deaeration on vacuum filling lines. Pouches can be supplied plain for fast sampling or printed by 10-colour rotogravure with registration control for brand, batch and EU label information. Filling trials, seal-strength checks and artwork proofs are available before mass production, with MOQ from 10,000 pouches per size and design for custom printed orders.
For sauerkraut brine, the pouch is filled through the open top and vacuum-sealed before final edge trimming, so the filling line needs suitable vacuum chamber or nozzle equipment rather than a spouted filler. The flat vacuum format stacks efficiently for case packing and uses less headspace than rigid jars, supporting transport and warehouse efficiency. Capacity options cover 1 l, 2 l, 3 l and 5 l, with gusset or flat configurations adapted to your filling nozzle, product viscosity and pallet plan. Seals are specified with controlled temperature, pressure and dwell time, and we recommend trials with your actual brine to confirm seal integrity, drop performance and leakage resistance. No standard spout or valve is included; contact us to discuss whether a fitment-led format is appropriate for your process.
Food-contact grade film is used for the product-contact layer, with material declarations and migration documentation discussed against the final formulation and EU requirements. For PPWR-aligned projects, we can evaluate PE-heavy or mono-PE structures, reduced pack weight and print coverage, provided the brine’s acidity and salt content still meet the agreed shelf-life and seal-performance targets. Artwork can be produced for 10-colour rotogravure printing, including German-language labelling, batch coding areas and recyclability information. Sampling typically starts with plain or digitally proofed pouches, followed by printed production samples after artwork approval. Custom printed MOQ is 10,000 pouches per size and design; lead time is usually 15–20 working days after final artwork and sample approval, subject to material and capacity confirmation.
