Key Product Features

A programmable heat-seal platform - full pressure/temperature/time programming with custom molds for seal evaluation across package types.

Teflon-Coated Heated Platen

Teflon coating prevents sticking; small platen-to-platen differential and stable long-term high-temperature operation ensure consistent seal quality.

TPR Temperature-Control System

The phase-controlled power system precisely controls heating temperature with smooth ramp and small fluctuation.

Three Programmable Parameters

Pressure, temperature and time - the three key process parameters - are centrally programmed for intuitive operation and reproducible processes.

Method Storage/Recall

Test methods and parameters can be saved and recalled; batch testing needs no re-setup, and data is traceable.

Custom Heated Molds

Heated molds are customized to the container design and package shape, suiting flexible packaging, irregular containers and other seal forms.
