Solutions for Wrinkled Pouches & Poor Sealing
Pouch wrinkling, seal leakage and edge cracking often cause food spoilage, off-shelf sales and customer claims.
1. Solve pouch wrinkling
- Choose high-stiffness laminated films, anti-extrusion and anti-humidity deformation
- Adjust production machine tension reasonably
- Keep finished goods dry and moisture-proof
- Standardize loading way to avoid heavy pressure
2. Optimize sealing performance
- Match accurate heat seal temperature and pressure by different materials
- Adopt functional seal layer: antistatic, acid & alkali resistant, metallocene material
- Use temperature-resistant sealing layer to prevent cracking and air leakage in long-distance transport
3. Strict quality inspection before shipment
- Implement air leakage test and full visual inspection per batch
- Adopt solid outer cartons and buffer packing materials
Reliable packaging quality effectively reduces after-sales issues and supports long-term business cooperation.
