Common Problems in Heat Sealers and How to Fix Them

Even the best heat sealing machine can develop issues over time — especially with heavy daily use. From poor seal quality to overheating or breakdown, small problems can cause major losses in production.

At Shree Shree Weighing Solutions, we offer repair and maintenance support for heat sealers across Ahmedabad. Here’s a troubleshooting guide to help you identify and fix common issues quickly.

• Insufficient pressure

• Wrong pouch material

Fix:

• Increase temperature incrementally (check melting point of pouch type)
