Laboratory Plastics Film Biaxial Stretch Tester

• The tensile strength, breaking strength and elongation of the film are measured in two mutually perpendicular major axis directions. These mechanical property parameters can evaluate the comprehensive mechanical properties and anisotropy of the film.
• The tensile stress-strain curves of the film in the two major axes can be measured simultaneously, which can visually reflect the mechanical response behavior of the film.
• It is possible to observe the microscopic morphological changes of the film during the stretching process, such as orientation and detailed surface. This is useful for studying the formation mechanism and improvement of the film.
• The tensile properties of films can be measured under different temperature or humidity conditions to study the influence of environmental factors on their mechanical properties.

• The laboratory plastics film biaxial stretch tester can simultaneously test the tensile properties of films in two mutually perpendicular major axis directions, which cannot be achieved by a unidirectional tensiometer. This can comprehensively and accurately evaluate the mechanical isotropic properties of the film.
• This equipment adopts specially designed choke sheet and fixture for film materials, which can accurately grip and transport film samples, and is not easy to produce slippage and damage, so the test results are accurate and reliable.
• The stretching speed and environmental conditions can be easily changed to study their effects on film stretching properties. This is useful for optimizing film processing and improving product performance.
• With advanced sensors and data acquisition system, important data such as stress, strain and engineering stress-strain curve can be displayed and recorded in real time during the bi-directional stretching process. These data can be used for in-depth analysis of the film deformation mechanism.
• Simple structure, easy operation and maintenance, lower testing costs, more suitable for product quality control and general laboratory use.

• The mechanical properties of various plastic films, such as PE, PP, PET, EPTFE and other films, are tested. These films are widely used in packaging, building materials, medical and other fields, and their mechanical properties directly affect the performance of the products, so they need to be evaluated and controlled systematically.
• The mechanical properties of various polymer composite films, such as film + film or film + non-woven fabric, are tested. These new high-performance films need a comprehensive understanding of their mechanical properties to facilitate product design and application.
• Mechanical property evaluation of various biodegradable films. These new environmentally friendly films need to be clearly understood in terms of their mechanical properties and degradation characteristics before application, as an important reference basis for product design and material selection.
• R&D and performance optimization of new high-performance films. In the process of new product development, film samples produced under different formulations or processes need to be systematically tested to find the best formulation and process parameters, which requires efficient and accurate mechanical property testing of various samples.
• Evaluation of physical aging or environmental aging effects of films. By testing the mechanical properties of old and new samples of the same batch of films or samples stored in different environments, we can find out the changes of film properties during the aging process, which can provide important references for product quality control and life estimation.
