Custom Frosted Zipper Bags
Sourcing Custom Frosted Zipper Bags from Dongguan Runsheng Packing Industrial Co., Ltd - China Import Guide
Verify the material type - LDPE or HDPE - before ordering, as performance differs significantly under load and temperature. Request a sample to test seal integrity, handle strength, and print adhesion. Confirm that the printing process uses food-safe inks if the bags will be used in environments where product contact is possible. Do not assume material properties based on marketing terms alone.
Confirm the Incoterms offered, typically FOB Guangzhou or EXW Dongguan. Lead time for custom-printed orders ranges from 18 to 30 days, depending on print complexity. Packaging is usually flat-packed in cartons, but palletization and shrink-wrap options should be confirmed. Payment terms are often 30% deposit with balance before shipment, though some suppliers accept LC at sight for larger orders.
Conduct a pre-shipment inspection focusing on seal strength, handle durability, and dimensional accuracy. Use a tensile tester to validate seal integrity and a micrometer to check thickness variation. Ensure print alignment matches the approved artwork and that there is no smudging or ink bleed. Request a certificate of compliance for material composition and a batch test report for physical properties.
