Liquid detergent pouch manufacturers

Liquid detergent pouches must utilize multi-layer laminated films (such as PET/NY/PE or PET/AL/PE) to ensure high barrier properties. The Nylon (NY) layer is critical for puncture resistance, while the Polyethylene (PE) inner layer must be of a special high-sealability grade to withstand the chemical surfactants in the detergent and prevent stress cracking or leakage during transport.

For industrial or retail refill use, tamper-evident screw caps are mandatory to ensure product integrity. You should specify anti-choke cap designs if the product is intended for household environments. Additionally, ensure the spout diameter (typically 8.6mm to 15mm) is compatible with your automated filling lines to avoid production bottlenecks.

Suppliers should provide UN Certification if the detergent contains hazardous chemicals. For general consumer safety, ensure the materials are BPA-free and comply with REACH or RoHS standards. If you are targeting the US market, verify that the packaging meets ASTM D3475 standards for child-resistant packaging where applicable.

Request Rotogravure printing for high-volume orders, as it offers the best color consistency and sharpest graphics. Ensure the supplier uses surface-protected inks that are resistant to chemical spills and friction, preventing the branding from peeling or fading when exposed to the detergent itself during the filling process.

Liquid pouches are susceptible to compression damage. You must require the supplier to use 5-layer corrugated export cartons and plastic pallets with shrink wrap. Request a drop test report (ISTA 1A or 2A) to ensure the pouches can survive the pressure of being stacked in a shipping container for 30+ days.

MOQs for custom-printed pouches are usually determined by the minimum run of the printing cylinders (often 10,000–30,000 units). To lower costs, consider ordering multiple SKUs (scents/sizes) in one batch to leverage total volume. For long-term cooperation, negotiate a stock-holding agreement where the supplier keeps a 2-month buffer of unprinted or printed film to shorten lead times.

Always prioritize Audited Suppliers who have undergone on-site inspections by third-party agencies like SGS or Intertek. Use the Secured Trading Service on Made-in-China.com to ensure that payment is only released to the supplier after you have confirmed the Bill of Lading or received a satisfactory Pre-shipment Inspection (PSI) report.

Shipping empty pouches is highly cost-effective as they are shipped flat, significantly reducing volumetric weight. If you are shipping to the US or EU, ensure the HS Code (typically 392321 or 392329) is correctly declared to avoid anti-dumping duties or customs delays related to plastic packaging waste regulations.
