Water-soluble film directly decides laundry pod quality. Reliable laundry pods manufacturers manage quality across 5 stages from incoming materials to warehousing.
1. Film Incoming Inspection
- Check film model, thickness uniformity and tensile property
- Test temperature and humidity tolerance
- Store separately by batch with clear labels
2. Production Process Control
- Match heat-seal temperature and pressure to film type
- Regular sampling to verify sealing firmness
- Control workshop humidity to avoid premature softening
3. Liquid-Film Compatibility Test
- Mandatory test before new formula mass production
- Check for film swelling, penetration and rupture risks
- Eliminate raw materials that accelerate film aging
4. Finished Product Sampling
- Inspect appearance, leakage and deformation
- Simulate high-temperature transit environment test
- Keep batch samples for full traceability
5. Warehousing Quality Management
- Stable temperature and humidity storage
- Avoid heavy stacking pressure on pods
- Follow first-in first-out principle
