C681M Flex Durability Tester

C681M Flex Durability Tester

Product catalog summary

Overview
The C681M Flex Durability Tester is designed to assess the flex durability of flexible films, composite films, and coating films. It simulates the kneading and creasing actions that occur during production, processing, and transportation. The durability is evaluated by measuring changes in pinholes or barrier properties, providing a quantitative basis for package design and practical usage.

Product Features

Offers five standard test modes (A, B, C, D, E) and one customizable mode (F) for flexible test cycles.
Equipped with four stations to enhance testing efficiency.
Features a fast switch between long and short strokes.
Displays and records testing environment temperature and humidity in real-time.
Controlled by a servo motor for precise displacement with dual protection and auto-reset for safety.
Includes an industrial-grade touch screen with a user-friendly interface, supporting remote upgrades and maintenance.
Supports both Chinese and English languages, with automatic data storage and power failure memory functions.
Can store up to 1200 test records, with easy data review and printing capabilities.
Offers multi-level user privilege management with password login.
Optional micro-printer for data exporting and transfer.

Test Standards
Complies with ASTM F392.

Applications

Suitable for testing flexible films, composite films, and coating films, including plastic films, sheets, aluminized films, aluminum plastic composite films, nylon films, and coating films for food or drug packages.
Applicable for testing the flex durability of paper materials.

Catalog excerpts

C681M Flex Durability Tester Labthink C681M Flex Durability Tester is professionally applicable to the determination of flex durability of flexible films, composite films and coating films. The instrument can simulate the kneading and creasing behaviors of films happened during production, processing and transportation. The flex durability can be obtained by measuring the changes in number of pinholes or barrier properties after test, which can provide quantitative basis for package design and practical usage.
