A properly sealed case protects products from tampering and damage and can help you meet regulatory requirements. Problems with achieving an effective seal can become time-consuming and costly to address. Learn how to overcome common case sealing challenges to keep your packaging line moving smoothly.
Insufficient Seal Strength
Seal strength measures how well the packaging material surfaces (e.g., two box flaps) are bonded together. Weak seals can lead to cases opening in transit, causing product damage and potential losses. To avoid this, invest in high-quality case sealing equipment that meets your production needs.
Maintain and calibrate the sealing machinery regularly to ensure consistent, strong seals. Machines require daily cleaning, and you should promptly replace worn or damaged parts. You may need to check the machine for obstructions, particularly in the tape roll areas or the cutting blades.
Poor Seal Adhesion
Poor seal adhesion occurs when something causes the tape to not bond well to the packaging material. Factors that can cause inadequate seal adhesion include using the wrong adhesive type for the packaging, dusty surfaces, and incorrect sealing temperatures.
Ensure you’re using tape that’s compatible with the case material. Moreover, be sure to keep package surfaces dust-free. A high-quality case sealing machine will apply the tape with a strong wipe-down force to ensure a secure seal.
Inconsistent Taping
Inconsistent taping may mean that the machine creates a partial seal or applies the adhesive unevenly, compromising the integrity of the carton. Inconsistent taping can also lead to uncut tape, wasting this material.
In your equipment inspections, check the condition of the tape head, blades, rollers, and drive belts to ensure they are aligned and clean. Also, keep the sensors clean, as these allow the machine to correctly size up each package to apply tape in the right areas. When the equipment’s parts are properly aligned and cleaned, the case sealer will work as intended and tape consistently.
Insufficient seal strength, poor seal adhesion, and inconsistent taping are common case sealing challenges you can overcome by maintaining your case sealing equipment and using the appropriate adhesives for your cartons and environment.
