Poly bag for garments

Selecting the appropriate material is critical for both protection and brand image. LDPE (Low-Density Polyethylene) is the industry standard for its softness and high clarity, while PP (Polypropylene) offers superior crispness and gloss for high-end retail. For thickness, 25 to 50 microns (1-2 mil) is standard for lightweight apparel like T-shirts, whereas 60+ microns is recommended for heavy outerwear or knitwear to prevent punctures. Always ensure the material is 100% virgin resin to avoid the yellowish tint and odor associated with low-quality recycled plastics.

International trade regulations mandate specific safety features for plastic bags. Most critically, bags with an opening of 5 inches or larger must feature a Suffocation Warning printed in multiple languages. For the EU market, ensure compliance with the REACH regulation regarding phthalates and heavy metals. If your brand prioritizes sustainability, look for suppliers providing GRS (Global Recycled Standard) certification or biodegradable options (PLA/PBAT) that meet EN 13432 standards.

For cross-border e-commerce, efficiency is key. Choose bags with a resealable adhesive strip (for easy returns) or a permanent destructive seal (for anti-theft security). To prevent moisture buildup and the 'ballooning' effect during shipping, ensure the bags have vent holes (air holes). Additionally, specify anti-static treatments to prevent the bags from sticking together, which significantly speeds up the manual packing process in warehouses.

Branding is often the first touchpoint for a customer. Request Copperplate (Gravure) printing for high-precision logos and vibrant colors, as it is superior to flexographic printing for complex designs. Verify the ink adhesion by performing a 'tape test'—applying 3M tape to the print and pulling it off to ensure no ink peels away. Ensure the supplier uses eco-friendly soy-based inks to align with modern environmental expectations.

Always request a pre-production sample before the full run. For large-scale orders, hire a third-party inspection service (like V-Trust or QIMA) to perform a random check based on AQL 2.5/4.0 standards before the final payment. On Made-in-China.com, prioritize 'Audited Suppliers' who have undergone on-site verification of their manufacturing capabilities.

Poly bag pricing is highly sensitive to raw material (petroleum) market fluctuations. Negotiate a tiered pricing structure based on volume; typically, increasing an order from 10,000 to 50,000 units can reduce the unit price by 15-25%. If you are a startup, look for suppliers on Made-in-China.com that offer flexible MOQs by using standard sizes while customizing only the print.

Poly bags are relatively heavy but low-volume when compressed. For cost-efficiency, use Sea Freight (LCL) for large volumes. Ensure the supplier uses strong 5-layer corrugated export cartons and palletizes the load to prevent moisture damage during sea transit. For urgent stock-outs, Air Freight is viable but will significantly impact your margins due to the weight of the plastic.

Utilize the Secured Trading Service provided by Made-in-China.com to protect your payment. Never transfer funds to a personal bank account; always ensure the beneficiary name matches the company name on the business license. Using Letter of Credit (L/C) for very large orders or Telegraphic Transfer (T/T) with a 30% deposit and 70% balance against the Bill of Lading (B/L) is the industry standard.
