Function Of Package Leak Tester

Helps you evaluate the seal integrity of flexible packaging used in food, pharmaceutical, daily chemical, electronics, and related industries.

Allows you to observe leakage, creep, rupture, and seal changes under stepped pressure conditions.

Supports automatic seal integrity testing by monitoring pressure changes during the test process.

You can use single-point mode, pressure increment mode, and decay mode to meet different daily QC testing needs.
Package Leak Tester For Better Flexible Packaging QC
Small sealing defects can cause leakage, contamination risks, shorter shelf life, and customer complaints. For packaging manufacturers and QC teams, the key is not only finding leaks, but also checking whether the sealing process stays stable across different batches and materials.
The FOLISTECH Package Leak Tester helps you evaluate package seal performance before storage, shipment, or market release. You can use it for incoming packaging inspection, production sampling, sealing process verification, and final product QC, helping your team reduce packaging failure risks and make release decisions with greater confidence.

Customer Feedback For Our Package Leak Tester
A Package Leak Tester helps you find weak seals, small leaks, and potential package failure risks before products leave your factory. This helps reduce leakage complaints, product returns, and quality disputes after shipment.
Yes. You can use it for many flexible packaging types, including pouches, sachets, bags, and sealed packages used in food, pharmaceutical, daily chemical, and electronics packaging applications.
Seal integrity testing helps you confirm whether your packaging can protect the product during storage, handling, and transportation. It gives your QC team a clearer basis for release decisions instead of relying only on visual inspection.
Yes. You can use regular leak testing to compare seal performance across different batches, materials, sealing temperatures, or production lines. This helps your team identify process changes before they become larger quality problems.
Yes. The instrument is designed for daily packaging QC, production sampling, incoming packaging inspection, and final product checks. It helps your operators perform repeatable leak testing with a more standardized workflow.
It can help you identify leakage risks, weak seals, poor heat sealing, packaging damage after handling, and seal failures that may affect product shelf life, cleanliness, or customer acceptance.
For food and pharmaceutical packaging, reliable seal integrity is important for product protection, contamination risk control, and shelf-life stability. A Package Leak Tester helps you verify packaging performance before products move to storage or market release.
