Material Withstands Pulling Force

Tear resistance fundamentally describes a material’s ability to withstand a pulling force that attempts to propagate a pre-existing cut or flaw. It is a measure of how much energy is required to continue a tear once it has been initiated, which is different from a material’s overall tensile strength. This property is critical in applications where small punctures or nicks are common, as a highly tear-resistant material will prevent a minor damage from turning into a catastrophic failure. The standard method for quantifying this involves using a specialized tensile testing machine to measure the force needed to extend a tear in a precisely prepared sample. This data allows engineers to compare materials and select the most appropriate one tailored to specific functional requirements—such as easy-open features for consumers or high-impact durability.

Fabric Resists Ripping Damage

When a fabric or film is described as tear resistant, it means it has a high resistance to ripping damage when subjected to a sudden or sustained stress. This is often achieved through the material’s internal structure, such as a tight weave, laminated layers, or the inclusion of reinforcing fibers that help distribute the force away from the point of stress. The goal is to prevent a small snag from developing into a large, compromising rip. Testing these properties is essential for quality control, and companies like Labthink provide the equipment necessary to perform these evaluations accurately. Understanding a material’s tear resistance helps manufacturers create longer-lasting products, reduce warranty claims, and enhance user confidence in items ranging from industrial membranes to packaging materials.

Strong Material Prevents Tearing

A strong material that prevents tearing is engineered to absorb and dissipate energy rather than allowing it to concentrate and cause a rupture. This characteristic is not just about raw strength but also about toughness and elongation—the material’s ability to stretch and deform slightly without failing. Factors like polymer composition, fiber orientation, and manufacturing processes all contribute to a material’s final tear resistance. For instance, a fabric with a rip-stop grid is designed to localize tears within a single square of the grid. By scientifically measuring this property, manufacturers can predict real-world performance, ensuring that products can endure the rigors of their intended use without succumbing to tearing forces, thereby improving durability and functional lifespan.

Flip-caps have various shapes and materials, whether square or round, metal or plastic, the opening force of the cap is the most concerned problem of manufacturers and users. If the opening force is too great, user will not only feel difficult to open, but also the opening process will even result in the deformation of the packaging containers. If the opening force is too small, the possible leakage is unsafe to the user. So, the opening force test of the flip-cap is very necessary.

At present, there is a professional flip-cap opening force tester on the market, it can also test plastic film, sheet, tube, adhesive, rubber, combined closure, paper and other products of their puncture force, opening force, low speed unwinding force, pulling force and other performance process detection by the tester. Through the microcomputer control of plastic flip cap , LCD displays data, results, curve, fixed extension stress, elastic modulus, stress strain and other test parameters to reflect the opening capability of plastic flip cup. Labthink XLW (PC) Tensile Tester can detect the opening force of flip cap of different shapes and materials, and help the production enterprises of flip caps to adjust and control the production process.

XLW (PC) Tensile Tester is professional to test tensile performance and mechanical properties of all kinds of flexible packaging materials, which is suitable for plastic film, adhesive agent, adhesive tape, medical plastic paste, protective film, flip cap, back panel material, non-woven fabric, rubber, paper fiber and other products of their stretching, stripping, deformation, tearing, hot sealing, bonding, puncture force performance tests. Its high accuracy (level 0.5) ensures the accuracy of the test. Seven independent test procedures, multiple force value sensors, and seven test speed selection can meet the users’ different test needs. Its intelligent operation software not only facilitates the user to control the equipment, but also provides a variety of practical functions such as data analysis and comparison.

Of course, the opening force of the flip cap is a concern in the use of the product, but it is far from enough for the quality control of the manufacturers. After ensuring the opening force of the bottle closure, some other items, such as the overall sealing performance of the packaging bottle, are controlled to ensure the quality and safety of the products.

The compound fastness between the mono layers of the composite packaging film is measured by the peel strength, which is one main property used to evaluate the quality of composite packaging film.

In practical application, if the peel strength of the composite film is too low, delamination may occur to the film after the content is packed inside the package. As a result, the barrier property as well as mechanical properties e.g. impact resistance of the packaging material may be compromised.

This article provides a simplified test method for the peel strength of the aluminum plastic composite package for meat products. The test specimens are provided by one meat product manufacturer. The testing instrument we used for the tests is Labthink’s C610H Auto Tensile Tester.

The tests shall be performed according to the following procedures.

(1)    Cut specimens from the sample material along machine direction and transverse direction. 5 pieces of specimens for each direction. The size of the specimen should be 200mm by 15mm.

(2)    Peel the specimen from one end by 50mm along the machine direction as is shown in the figure below.

(3) Clamp the two ends of the peeled part of the specimen with the upper and lower sample grips. Make sure the longitudinal axis of the specimen coincides with the line of centers of the uppwer and lower sample grips.

(4) Set test speed, specimen width and other test parameters.

(5) Click Test to start the test. The system will record the peeling forces in the testing process, calculate and display the final test results automatically.

In medical industry, blister packaging is commonly used as unit-dose packaging for pharmaceutical tablets, capsules or lozenges. The medicines are held in the blister cavities, which  are separated medicines from each other. Even though one blister cavity is broken, others can keep intact. Therefore, heat seal strength of the paperboard or aluminum foil should be adequate. Otherwise when one tablet or capsule is removed from the blister package, other blister cavities may be broken and then medicine may be oxidized and damped. Therefore it is necessary to test the heat seal strength of the medical blister packaging to guarantee the quality of medicines contained inside.

Figure 1. Medical Blister Package

How to know and make sure if the blister packaging has enough seal strength？ What manufacturers can do during the packaging producing? We will discuss these with assistance of a Tensile Strength Tester.

Step 1: Seal the rigid PVC sheet and aluminum foil with Labthink HST-H3 Heat Seal Tester under specified conditions (sealing temperature 155±5℃, sealing pressure 0.5MPa, dwell time 1 second).

Step 2: Cut 3 pieces of specimens whose length should be 15mm.

Step 3: Mount the prepared specimen in the sample grips of XLW  Auto Tensile Tester. Select test speed 200 mm/min and then start test. When test is finished, the instrument will calculate and record the test results automatically.

According to the test results given by the instrument, the manufacturer can determine whether the blister package can meet their requirements for packing of medicines.
