Frequently Asked Questions
Q1: What is the difference between 8021 and 8011 alloy for cold forming foil?
A: 8021 alloy offers higher strength and better elongation, making it more suitable for deep-drawn blister cavities. 8011 alloy is more cost-effective and works well for standard shapes. Both are available, and we can recommend the best option based on your blister design.
Q2: Can this foil be used for heat-seal coating?
A: Yes, our foil has a clean surface with low oil residue, allowing easy application of heat-seal lacquer or PVC coating. We can also supply pre-coated foil upon request.
Q3: What is the typical lead time for orders?
A: For standard sizes, lead time is 15-20 days after confirmation. Custom dimensions may require 25-30 days, depending on the quantity. We ship from Qingdao port.
Q4: Do you provide samples for testing?
A: Yes, we offer free samples (A4 size or small rolls) with freight collect. Please contact us with your requirements.
Q5: What packaging options are available?
A: Foil is supplied in coils with inner diameter of 76 mm or 152 mm, wrapped in moisture-proof packaging. Custom packaging (e.g., wooden spools) is available.
Q6: Is this foil suitable for child-resistant blister packaging?
A: Yes, the cold forming alu alu foil can be combined with push-through or peel-off backing materials to meet child-resistant standards. We can provide technical guidance.
Q7: How do you ensure thickness uniformity?
A: We use automatic gauge control (AGC) systems during rolling, and every coil is inspected with a pin-hole detector and thickness gauge. Our tolerance is within ±5% of specified thickness.
Q8: What certifications do you hold?
A: Our facility is ISO9001:2015 certified. We can also provide test reports for material composition and mechanical properties upon request.
