At Labthink, we understand that our experienced clients—those in quality control and R&D for flexible packaging—do not require a general overview of every testing machine on the market. Instead, they require precision tools tailored to the specific, low-force demands of films, foils, and laminates. Therefore, when discussing types of tensile tester equipment, we narrow the focus to instruments designed for the sensitivity and high resolution demanded by our specialized industry. Our perspective is defined by the necessary application: testing thin, flexible materials. We categorize the types of tensile testing machines not by their historical evolution or capacity for heavy metals, but by the practical configuration best suited for flexible packaging analysis.
Types of Tensile Tester Equipment for Flexible Materials
The most relevant categorization for our clients centers around the design and capability of the equipment needed to accurately measure the mechanical properties of packaging films and related flexible materials. The core instruments we utilize are Universal Testing Machines (UTMs) that are specifically configured for low-force, high-elongation tests.
Single-Column (or Benchtop) Universal Testing Machines
This is the most common and versatile type of tensile tester used in quality control and research labs focused on flexible packaging.
Design Focus: These systems are engineered for the low to moderate force ranges—typically up to 1kN or sometimes slightly more—required for films, adhesives, paper, and non-woven materials. They are compact, designed for placement on a lab bench, and prioritize resolution over sheer force capacity.
Ideal Application: Perfect for measuring the tensile strength and elongation of plastic films (e.g., ASTM D882), 180 Degree Peel Test of laminates (e.g., ASTM F88), and the basic tearing and puncture resistance of pouches.
Labthink Example: Our C610M Auto Tensile Tester exemplifies this type. It is specifically designed with a high-resolution load cell and a generous stroke to accommodate the high-elongation properties of flexible materials without compromising accuracy.
For Labthink clients, our focus remains on providing the appropriate benchtop solution, like the C610M, as its capabilities sufficiently cover the vast majority of international standards for flexible packaging materials. We specialize in ensuring the accuracy and compliance of the instruments within their designed operational envelope, rather than pushing high-force boundaries.
Beyond Tensile: The Integrated Lab Approach
A complete mechanical profile of a flexible packaging material requires more than just a tensile tester. For experienced professionals, the comprehensive lab setup integrates multiple specialized pieces of tensile testing equipment and related instruments to ensure the material performs optimally.
For instance, the slip properties of a film are just as critical as its strength. The coefficient of friction affects how smoothly the material runs on high-speed packaging lines, and this requires dedicated coefficient of friction test equipment. While separate from the tensile testing machine, our instruments for CoF measurement, like the MXD-02, are a necessary complement. The data from a tensile tester (strength) and coefficient of friction test equipment (slip properties) provide a complete picture of the film’s processability and integrity. Our clients often rely on us to provide this integrated suite of instruments, as poor CoF can lead to jamming and tearing, effectively undermining the film’s measured tensile performance.
The Labthink C610M Auto Tensile Tester: Precision Specifications
The C610M is not simply a type of tensile tester; it is a high-resolution instrument precisely configured for flexible materials. We equip the C610M with a standard 500 N load cell, though it is scalable with options ranging from a very sensitive 5 N to a robust 1000 N. Critically, its force resolution is 0.001 N, which ensures that minute forces—like those involved in the initiation of a tear in a thin film—are captured accurately.
The testing speed is infinitely variable up to 500mm/min, which is vital for adhering to various international standards. Furthermore, the C610M is designed to be multifunctional, offering ten independent testing modes, including: tensile, peel, tear, heat seal strength, and puncture. This versatility means that our experienced clients can perform a broad array of required mechanical tests on a single, reliable tensile testing machine.
