IX. FAQ – Technical & Industry Q&A
Q1: What material options are available for zipper packaging bags and how do they impact barrier properties?
A: Common materials include
LDPE, LLDPE, PET, BOPP, and biodegradable blends. PET/PE and metallized structures offer high oxygen and moisture barriers, crucial for food and electronics. Compostable films are available for sustainability but may offer lower barrier performance.
Q2: Which certifications should a high-quality zipper packaging bag possess?
A: FDA for food safety (21 CFR 177.1520), EU 10/2011, ISO 9001:2015 QMS, BRC for food contact, and EN ISO 11607 if used in medical packaging. Top manufacturers provide certificate copies upon request.
Q3: How is the zipper strength tested and specified?
A: Zipper tensile is measured in Newtons per 15mm (ASTM D882); premium bags exceed 11N/15mm after 100 open-close cycles. Automated QC draws sample data to verify spec per batch.
Q4: What installation and filling machine compatibility is required for auto-packing lines?
A: Bags are typically compatible with HFFS/VFFS machines (Bosch, Hayssen, etc.), validating zipper closure under both manual and inline high-speed filling. Refer to DIN 55405 for flexible packaging machinability standards.
Q5: What is the typical lead time and minimum order quantity for custom packaging zip bags?
A: Custom projects start from 5,000–10,000 pcs, with lead times of 8–16 working days post artwork approval. Expedited rush support is possible for urgent B2B orders—contact
Junlanpack for live schedule.
Q6: How does temperature and humidity affect zipper bag storage and shelf life?
A: Premium
zipper packaging bag films retain flexibility from -30°C to +100°C. Store finished bags in cool, dry, and shaded warehouse—shelf life ≥24 months is typical per ISO 8367-1.
Q7: What technical supports are available for custom development?
A: End-to-end DFM, OEM/ODM design, on-site printing proofing, mechanical fit-testing, accelerated barrier testing (ASTM F1249), and digital artwork templates are offered by certified suppliers.
