Impulse Sealing Blade Troubleshooting Tips
Thursday, September 1st, 2011
Impulse sealing blades are the most common method used to seal and cut shrink film and other plastic materials. In relation to shrink-wrap machines, and even many heat sealers, the blade will eventually begin to dull and efficiency will begin to wane. Bad sealing blade symptoms include cracked blades, built-up blade corrosion and the inability to cut film. Here are a few tips that will help you to extend the life of your impulse sealer.
Impulse Sealer Troubleshooting Tips
- If you are having issues with your bags or film not properly sealing, try lowering the seal time. The less time that is put on a seal, the stronger it should become.
- I recommend not exceeding 1.8 seconds when sealing. That should provide the beset seal. A longer sealing time will only compromise the seal and decrease its strength.
- I recommend cleaning the sealing blade on your shrink wrap machine or heat sealer with either a cleaning gel or with silicon spray. This can potentially extend the life of the sealing blade by up to 12 months. Contact our Service Department at 1-800-658-8788 x129 for shrink-wrap machine and heat sealer cleaning supplies.
