2. Can the heat seal be reopened and resealed?
Yes, we offer dual-function designs: a permanent heat seal for initial closure and a resealable zip lock for repeated use, ensuring long-term freshness after opening.
3. How do you ensure the heat seal quality for bulk orders?
Our production line includes 6 quality inspection machines that test seal strength, airtightness, and consistency. Every batch undergoes random sampling to meet ISO9001 standards.
