Issue: Cardboard-Foil Liners Are Prone to Damage from Inner Edges
Wheel-type safety caps feature a distinctive "wheel" design, often including inner ridges or reinforcing ribs to improve compression strength and tamper resistance. However, these structural elements pose a risk-cardboard-foil liners may be scratched or punctured by the cap's inner edges during assembly or transit, leading to compromised sealing performance and even product leakage or failure.
Recommendations and Solutions
To prevent such issues, we recommend customers contact us in advance when planning to use cardboard-foil liners with wheel-type caps. Based on the specific configuration, we can provide the following support:
- Optimized Packaging Method: We offer cap orientation and organized boxing services, helping prevent cap-to-cap contact and movement during transport, which reduces the risk of liner damage.
- Alternative Liner Options: For applications with higher sealing requirements, we suggest using pressure-sensitive liners or heat-seal liners, which offer better resilience and flexibility.
- Structural Optimization Advice: For customers with consistent order volumes, we can assist in adjusting the inner structure of the cap to reduce sharp-edge contact with the liner.
