Stop the Leaks with Proper Techniques
Torque and Alignment
Proper torque and alignment during cap application play a critical role in preventing leaks in lami tube packaging. Operators must apply the correct amount of torque to each cap. This practice ensures even pressure across the closure and reduces the risk of leaks. Over-tightening creates excessive pressure points, which can lead to uneven seals and possible leakage. Under-tightening results in inadequate sealing and increases the chance of leaks.
| Key Point | Explanation |
|---|---|
| Proper Torque | Ensures even pressure distribution across the closure, preventing leaks. |
| Over-Torquing | Can create excessive pressure points, leading to uneven seals and leaks. |
| Under-Torquing | Results in inadequate sealing, increasing the risk of leaks. |
Operators should verify application torque for every batch. They must avoid both over-tightening and under-tightening to maintain seal integrity. The alignment of caps with the tube is equally important. Misaligned caps can compromise the seal and allow leaks to occur. The lami tube making machine should be set to align closures precisely with the tube opening. Regular checks help maintain proper alignment and prevent defects.
Tip: Use visual guides or alignment tools to ensure caps sit squarely on each tube. This step reduces the risk of misaligned closures and helps stop the leaks.
Sealing Machine Calibration
Sealing machine calibration is essential for producing strong, reliable seals on laminated tube packaging. Operators must maintain supply roll tension throughout the process. Proper tension prevents wrinkles and misaligned seals, which can lead to leaks. If the supply roll tension drops, the tube material may shift, causing the seal to become uneven.
Regular calibration of the lami tube making machine ensures consistent pressure, temperature, and jaw alignment. These factors influence the quality of the seal. Operators should control pressure and dwell time to create a strong bond without damaging the tube. Real-time monitoring of sealing parameters allows for quick adjustments if deviations occur.
- Calibrate the sealing machine regularly to maintain consistent pressure, temperature, and jaw alignment.
- Monitor supply roll tension to prevent wrinkles and misaligned seals.
- Adjust pressure and dwell time for each batch to achieve a strong seal.
- Use real-time monitoring systems to detect and correct deviations immediately.
Operators should align the tube and tongue carefully before sealing. This step prevents misalignment and ensures the seal covers the entire opening. The use of strong materials such as PE, ABL, and PBL in lami tube packaging helps contain creams and lotions effectively. Proper sealing techniques, combined with high-quality caps and closures, minimize the risk of leaks and protect product integrity.
Note: Routine calibration and alignment checks on the lami tube making machine help maintain seal quality and reduce the likelihood of leaks.
Fix Your Packaging for Shipping
Protective Packing
Manufacturers must secure caps on lami tube packaging before shipping, especially when products experience temperature changes. Caps can loosen if exposed to fluctuations from 37°C to -80°C, as plastics contract in cold conditions. Operators should always check that caps are snugly fastened after any exposure to extreme temperatures. This step helps fix your packaging and prevents leaks during transit.
Best practices for protective packing include several steps:
- Use strong, corrugated cardboard boxes that match the weight and size of the products.
- Layer items with protective cushioning such as bubble wrap or foam inserts.
- Wrap each item individually to prevent contact and movement.
- Add anti-static materials to protect against electrostatic discharge.
- Fill empty spaces with packing peanuts or foam to prevent shifting.
- Label packages clearly with handling instructions.
Custom-fit packaging keeps products stable and prevents damage. High-quality packing materials absorb impacts and create a barrier against moisture. Waterproof liners protect sensitive items and reduce the risk of leaks. Foam inserts provide a snug fit, which is essential for keeping caps secure throughout shipping.
Tip: Always use liners and protective materials to shield tubes from rough handling and environmental changes.
Monitoring During Transit
Monitoring techniques help detect cap loosening or leaks during shipping. Pressure rise measurement is a reliable method. Operators place packaging in a vacuum chamber and monitor pressure changes. If the packaging is not airtight, gas escapes, causing a measurable pressure increase. Devices like the Contura S enhance accuracy and reliability in leak detection.
| Technique | Description |
|---|---|
| Pressure Rise Measurement | Packaging is placed in a vacuum chamber. Pressure changes indicate leaks. The Contura S device improves accuracy and reliability. |
Other monitoring methods include measuring force with a load cell as the package expands. These systems detect leaks by quantifying the rate of force decay over time. Sensitivity can reach holes as small as 5 microns. Data logging and traceability allow manufacturers to track packaging integrity throughout transit.
Regular monitoring ensures that lami tube packaging arrives intact and leak-free. By combining protective packing and advanced monitoring, manufacturers maintain product quality and customer satisfaction.
Troubleshooting Leaks and Misalignment
Common Causes
Leaks and misalignment in lami tube packaging often result from several recurring issues. Operators and quality teams should watch for these frequent problems:

- Leaks developing at transitions from two to four layers or at corners.
- Adjustments made to seal off leaks that create excess pressure points, leading to further complications.
- Variations in the thickness of the composite film, which can affect sealing parameters.
- Local seal leaks due to increased film thickness that require changes in heat and pressure.
- Foreign objects caught in the heat-sealing film, causing local sealing problems.
- Insufficient heat-sealing pressure and uneven mold surfaces, which can weaken the seal.
- Sudden changes in thickness in specialized areas, especially at the back seal or overlaps of side-sealed bags.
Note: Regular maintenance and calibration of equipment help prevent many of these issues. Operator training and clear standard operating procedures also support consistent results.
Quick Fixes
When leaks or misalignment occur, operators can apply several quick fixes to restore packaging integrity. The following table outlines practical steps:
| Quick Fix Description |
|---|
| Align tube and tongue so the center line of the tube is parallel to the carriage tracks. |
| Set sealer arm parallel to the jaws, with the sealer resting on the tube. Center line of the bar must match the tube. |
| Adjust the sealer bar so a 1/4″ gap remains at the top when the bottom of the bar contacts the tube. |
| Adjust spring tension to just hold the bar against the stop. |
Operators should also center the sealing jaws. Both the upper and lower jaws must align with the package to ensure a uniform seal.
Routine calibration of lami tube making machine remains essential. Incorrect calibration can cause overfilling, underfilling, or misaligned labels. Automated inspection systems with cameras and sensors can detect defects in real time. AI-based systems can even predict and prevent future issues by learning from defect patterns. When persistent problems arise, teams should reassess both equipment and materials. Sometimes, a packaging equipment assessment reveals that the film or closure type does not match the machine or product needs. Making these adjustments improves productivity and reduces costs.
