What the project must solve

01

Ultrasonic sealing depends heavily on material compatibility and clean material presentation.

02

Tea and filter applications need dosing accuracy, seal strength and attractive bag shape together.

03

Tooling, horn wear and material thickness should be reviewed before assuming all non-woven materials will run.

Buyer analysis

Where ultrasonic sealing fits

Ultrasonic sealing is common for tea bag and non-woven applications because it can join compatible materials without the same heat-seal approach used for film laminates. It is selected around material behavior, pack shape and product presentation.

Testing requirements

Send filter material, tag, string, envelope and product samples. The test should confirm sealing strength, cut quality, bag appearance, dose accuracy and whether product dust affects the seal area.

Common decision questions

Is ultrasonic sealing only for tea bags?

No. It is common in tea bags and non-woven packs, but the material must be compatible with ultrasonic joining.

Can ultrasonic sealing improve tea bag appearance?

It can support clean edges and premium bag shapes when material, dosing and forming are stable.

What should be checked during FAT?

Seal strength, bag shape, cut quality, dose accuracy, tag/string handling and envelope integration.
