Built as a liner bag for car wash concentrate, this package uses a chemical-resistant multi-layer structure such as coextruded PE or PET/NY/PE, with PET/AL/PE available for extra barrier where formulation requires it. The sealed liner is supplied with a 32 mm spout or dispensing valve for clean transfer into drums, jugs, bag-in-box outer cartons or refill stations. Common capacities cover 1 L, 5 L, 10 L, 20 L and 5-gallon formats; custom sizing is reviewed against fill volume, headspace and concentrate chemistry. For US East Coast distribution, we can quote UN transport configurations where the complete pack, outer packaging and documentation are specified together.
Filling can run on spout-insertion or bag-in-box lines: the empty liner is presented flat or gusseted, filled through the spout, then cap-torqued and leak-checked according to your line procedure. For brand presentation, the film can be surface-printed by 10-colour rotogravure with registration-controlled graphics, formulation and safety text, and bilingual East Coast labels. Minimum order quantities start from 10,000 bags per SKU for custom printing, with lower trial quantities reviewed for sampling. Sampling is handled through pre-production proofs and filled or unfilled sample bags so buyers can verify fitment, film hand, spout orientation and outer-carton compatibility before the production run.
For refill and reuse programmes, the liner bag keeps concentrate contained while the outer carton or reusable drum carries the structure, reducing package weight and waste in janitorial, car wash and light-industrial settings. The spout valve supports controlled pouring or closed dispensing; choose screw-cap, flip-top or valve fitments to match your dilution equipment and avoid cross-threading. Film and fitment combinations are selected for contact with car wash surfactants, builders and common additives, with compatibility confirmed against the actual concentrate before sign-off. Production lead times are typically quoted at 15–25 working days after artwork and sample approval, depending on film structure, spout type, print complexity and order volume.
