Polybag with plastic hanger

Buyers should prioritize LDPE (Low-Density Polyethylene) for high clarity and flexibility or PP (Polypropylene) for superior crispness and heat resistance. The thickness, typically measured in microns (μm) or mils, should be at least 50 microns for retail packaging to prevent tearing. For the hanger component, ensure it is made of heavy-duty Polystyrene (PS) or ABS to support the weight of the garment without snapping.

It is critical to verify that the bags are BPA-free and comply with REACH (EU) or CPSIA (US) regulations, especially regarding lead and phthalate content in plastic components. If your brand focuses on sustainability, request GRS (Global Recycled Standard) certified materials or biodegradable additives (like EPI or D2W). Additionally, ensure the bags include suffocation warning labels printed in multiple languages if they exceed a certain size.

Look for reinforced header cards where the hanger is attached to prevent the plastic from stretching. The sealing method is also vital; resealable adhesive strips allow for inspection without damaging the bag, while heat-sealing provides a permanent tamper-evident closure. For high-end apparel, ensure the bag has vent holes to allow air to escape, preventing the 'ballooning' effect during palletization and shipping.

Request a static load test report from the supplier. A standard retail hanger should typically support at least 2-5kg depending on the garment type (e.g., swimwear vs. heavy coats). The connection point between the hanger and the polybag is the most common failure zone; ensure it uses ultrasonic welding or heavy-duty rivets rather than simple glue.

The most common risks include material substitution (using recycled scrap instead of virgin resin, which affects clarity) and incorrect dimensions. To mitigate this, use Made-in-China.com's Secured Trading services and insist on a pre-shipment inspection (PSI) to verify the gauge (thickness) and tensile strength before the balance payment is released.

Since polybags are lightweight but bulky, shipping 'air' is expensive. Negotiate for vacuum-compressed packing or high-density carton stacking. For large orders, FOB (Free On Board) terms are generally more cost-effective, allowing you to use your own freight forwarder to consolidate shipments and manage customs clearance more efficiently.

Focus on volume-based pricing tiers. Because plastic resin prices fluctuate with the oil market, ask for a price validity period (usually 15-30 days). You can also negotiate a lower MOQ for trial designs if you commit to a larger annual volume, or ask the supplier to stock raw materials to hedge against price spikes.

Provide the supplier with specific Pantone color codes and request a digital or physical proof before mass production. Ensure the ink used is eco-friendly soy-based ink or UV-resistant to prevent color migration onto the garments inside. Verify the printing plate (Cylinder) costs upfront, as these are usually a one-time fee for each design.
