Detergent bags

Detergent bags must be constructed using multi-layer laminated films to ensure chemical resistance and structural integrity. For liquid detergents, a combination of PET/NY/PE (Polyethylene Terephthalate/Nylon/Polyethylene) is recommended to provide a high moisture and oxygen barrier, preventing leakage and scent loss. For powder detergents, PET/PE or BOPP/PE layers are often sufficient. Ensure the total thickness is at least 100-150 microns to prevent punctures during transit.

For liquid detergents, the spout design and sealing technology are critical; look for anti-choke caps and induction sealing to prevent leaks. For powder products, heavy-duty sliders or press-to-close zippers are essential for reusability. Additionally, stand-up pouches (Doypack) with a reinforced bottom gusset are preferred for retail shelf visibility and stability.

Suppliers must comply with REACH and RoHS regulations regarding chemical substances. Since detergents are household chemicals, the packaging should meet ISO 9001 for quality management and ISO 14001 for environmental management. If the product is destined for the US market, ensure materials are FDA-compliant if there is any risk of secondary contact, and check for UN Certification if the detergent is classified as a hazardous material.

Request Rotogravure printing for high-volume orders, as it offers the best color consistency and sharpness. Ensure the supplier uses eco-friendly, solvent-free inks that are resistant to the detergent's chemical composition to prevent ink peeling or fading. Ask for a tape test report and rub resistance test to validate print adhesion.

Request a Vacuum Leakage Test and a Burst Pressure Test report from the supplier before shipment. For bulk orders, it is advised to use reinforced 5-layer corrugated outer cartons and palletization with shrink wrap to minimize movement and compression damage during maritime transport.

Focus on the Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for free cylinder/plate making charges for long-term contracts or high-volume orders (typically over 50,000 units). Always request a pre-production sample for physical testing before releasing the 30% deposit, and link the 70% balance payment to a successful third-party pre-shipment inspection.

Be aware of Plastic Taxes and Extended Producer Responsibility (EPR) schemes in regions like the EU and UK. Discuss recyclable mono-material options (like PE/PE) or PCR (Post-Consumer Recycled) content with your supplier to avoid high import duties and ensure alignment with evolving sustainability regulations.

Utilize Secured Trading Services on Made-in-China.com to protect your funds until delivery. For shipping, choose Incoterms like FOB (Free On Board) to maintain control over freight costs and insurance. Ensure the Bill of Lading accurately describes the material composition to avoid delays during Customs Clearance.
