Troubleshooting Packaging Applications
Speed and efficiency are extremely important factors when it comes to packaging production lines. However, there are many factors that can cause unexpected downtimes that can be costly for manufacturers. Our experts have developed troubleshooting tips for common issues case and carton sealing manufacturers face to help prevent delays and provide high quality and reliable packaging for consumers. These include:
Pop Opens
Pop opens are a common packaging challenge that can happen on production lines, in transit or during delivery, causing expensive delays and effecting brands reputation. There are many possible reasons why the hot melt adhesive used to seal cases or cartons can pop open, such as the application settings, processing conditions, and bond failure due to external ambient temperatures. For this reason, troubleshooting hot melt pop opens is necessary to determine exactly what is causing the pop opens in order to fix the issue and prevent production downtimes.
Stringing
When hot melt adhesives do not properly separate from the applicator nozzle during application to cases or cartons, the adhesive can leave thin strands that float around the air. Besides the messy appearance, these strings can cause issues along the production line that lead to costly delays. There are a number of steps that can help prevent stringing, such as reducing the distance between the nozzle and the package and changing the configuration and nozzle type.
Char
When hot melt adhesive is heated for too long or at a temperature that is too high, the material can begin to burn, clogging filters, nozzles, and hoses while causing extensive production delays. Once char begins to form it is extremely difficult to remove, so preventing hot melt char is important for efficient production lines and reducing material waste.
Tank Pressure
Proper tank pressure is an important factor in keeping production lines running smoothly and avoiding unnecessary delays. As a key component of any hot melt adhesive system, tank pressure along with nozzles and application temperature determine the flow and dispensing rate during production. Thus, optimizing and maintaining proper tank pressure is important to prevent application issues or adhesive build up that can cause costly production downtimes.
Tank Refilling
In order to ensure that products arrive safely and securely at their final destination and prevent unplanned downtimes on the production line, it is important to establish a routine for hot melt tank refilling. Properly filled tanks keep the packaging adhesive at a constant temperature and prevent char from forming.
Nozzle Size
Precision and speed are two important factors for efficient packaging production lines. Therefore, it is essential to select the optimal size nozzle in order to have the correct flow and dispensing amount.
