GFT-01 gelbo flex tester is also known as Flex Durability Tester, assesses how well materials such as films, composites, and coating films endure repetitive strain. It helps to create flex failure on samples so user can identify pinholes and permeation ability change in the sample structure. The importance of achieving strong flex crack resistance lies in reducing the risk of packaging developing holes during distribution. This is crucial for keeping the package intact throughout its journey, ensuring the contents inside remain protected. The tester plays a key role in evaluating the ability of materials to withstand repeated flexing, contributing to the overall durability and reliability of packaging in various industries.

Advantages

GFT-01 Gelbo Flex Tester is equipped with PLC control and a user-friendly HMI touch screen interface. It encompasses five standard test modes and incorporates four test stations, allowing users to easily transition between long and short stroke modes by the selectable test conditions A, B, C, D, and E. Additionally, the inclusion of a micro printer ensures convenient and efficient data output.

Application: 

GFT-01 Gelbo Flex Tester is normally used for high barrier materials in various industries due to their protective properties. Here's a list of such materials and their common usage in industries:

1. Metalized Films:

   - Industries: Food Packaging, Pharmaceuticals

   - Usage: Metalized films provide excellent barrier properties against moisture and oxygen, making them suitable for preserving the freshness of food items and pharmaceutical products.

2. Polyethylene Terephthalate (PET) Films:

   - Industries: Electronics, Medical Devices

   - Usage: PET films with high barrier coatings are used to protect electronic components from moisture and chemicals. In the medical industry, they are employed for sterile packaging.

3. Polyvinylidene Chloride (PVdC) Coated Films:

   - Industries: Pharmaceutical, Food Packaging

   - Usage: PVdC-coated films offer exceptional oxygen barrier properties, making them ideal for pharmaceutical blister packs and food packaging to extend shelf life.

4. Ethylene Vinyl Alcohol (EVOH) Films:

   - Industries: Food Packaging

   - Usage: EVOH films provide an excellent oxygen barrier, commonly used in food packaging to extend the shelf life of perishable goods.
