How to evaluate the tensile strength, tear strength and puncture resistance of shrink film? What are the effects of these properties on packaging?

Tensile strength is one of the important indicators for evaluating the performance of film materials. It reflects the ability of the film to resist breaking when subjected to tension. For shrink film, higher tensile strength means that it can better adapt to the stretching requirements during packaging and ensure the tightness and stability of the packaging.
Evaluation method:
Sample preparation: Prepare film samples that meet the requirements according to the test standards and requirements. The sample should be flat, free of wrinkles, bubbles and other defects, and maintain a certain size and shape.
Instrument preparation: Select a suitable tensile strength test instrument, such as a universal material testing machine, and check its calibration and operating status to ensure the accuracy of the test results.
Testing process: Install the prepared sample on the fixture of the test instrument, set the appropriate stretching speed and preload force, and perform a tensile test until the sample breaks. Record the maximum force or stress value at the time of breakage, which is the tensile strength of the film.
Our company uses all imported high-quality raw materials, which have high strength and toughness, providing a solid foundation for the production of high-quality shrink films.
From film making to slitting to folding to packaging, every step is quality tested and BRC certified to ensure that the tensile strength and other performance indicators of the product are stable and reliable.
Tear strength refers to the ability of the film to resist breaking when subjected to tearing force. For packaging film, higher tear strength means that it can better resist tearing damage that may be suffered during packaging, transportation and storage, thereby protecting the integrity of the packaging.
Evaluation method:
Sample preparation: It is also necessary to prepare film samples that meet the regulations to ensure the flatness and defect-freeness of the samples.
Instrument preparation: Select an instrument suitable for tear strength testing, such as a tear strength tester, and calibrate and check it.
Test process: Install the sample on the fixture of the test instrument in the prescribed manner, and apply tearing force until the sample breaks. Record the force value or stress value at the time of break, which is the tear strength of the film.
Our company strictly controls suppliers and only uses imported advanced raw materials, which have high tear strength and can meet various complex packaging needs.
Through strict production process control and quality inspection, it is ensured that the performance indicators such as tear strength of each batch of products reach the optimal level.
Puncture resistance refers to the ability of the film to resist penetration by external sharp objects. For packaging film, good puncture resistance can effectively prevent sharp objects from damaging the packaging and ensure the safety and integrity of the packaging.
Evaluation method:
Sample preparation also requires the preparation of film samples that meet the regulations and simulate the puncture conditions in actual use.
Instrument preparation: Select an instrument suitable for puncture strength testing, such as a puncture strength tester, and calibrate and check it.
Test process: Install the sample on the fixture of the test instrument and use the specified sharp object to puncture the sample. Record the change in force or stress value during the puncture process, and whether the sample is penetrated or broken.
The imported raw materials used by our company have high puncture resistance and can effectively resist the penetration of sharp objects.
Through technical means such as multi-layer composite structure and enhanced surface treatment, the puncture resistance of shrink film is further improved.
Strict production process control and quality inspection ensure that the puncture resistance of each batch of products reaches the optimal level.
The impact of these properties on packaging effect
Tensile strength: High tensile strength ensures that the shrink film tightly wraps the product during packaging to form an effective protective layer. This helps prevent damage caused by loosening or separation during transportation and storage.
Tear strength: Higher tear strength can enhance the protection of shrink film to the packaged goods. During packaging, transportation and storage, the shrink film can maintain integrity even when it encounters tearing force, thus ensuring the safety of the packaged goods.
Puncture resistance: Good puncture resistance can prevent sharp objects from damaging the packaged goods. This is especially important for protecting fragile or sensitive products. By improving the puncture resistance of the shrink film, it can be ensured that the product can remain intact in various complex environments.
