Test Impact Resistance Strength of Plastic films and sheets using Dart Impact Tester

 

Plastic films are used in our daily life for various purposes. They are used to carry groceries, package food, cover vegetables grown in fields and greenhouses and so forth. Packaging with plastic films is common in the medical engineering industry also. Therefore, the manufacturers of plastic films need to measure the quality of the packaging products before using for the market. To ensure the quality and safety of the products, manufacturers and suppliers perform several quality tests. The appearance of the product matters a lot as it is responsible to grab the attention of the customers. Inferior quality hampers both product and customers with bad appearance or packaging.

How to perform the impact resistance test?

The understanding of the impact resistance of plastic films plays a very important role as the material is subjected to impacts at the time of transportation. This test method is used in packaging industries, laboratories, and film manufacturing units to measure the levelof weight impact their products can bear without failure.

The test procedure evaluates the impact strength of plastic films through an elaborated procedure. A weighted round shaped dart is released from a predetermined height onto a tightly clamped sheet of the film. The film sample is tested for failures visually. The dart impact value depends on the thickness of the film.

Falling Dart Impact Testis used to measure the resistance strength of plastic film against free-falling dart. The weight of the dart can fall from a specified height with a specified amount of energy and pass on the same to the tight stretched and clamped sample. If the quality of the sample is not good, it will rupture under specific conditions. The instrument used for testing helps in studying the behaviour of the plastic films when they are tested from a dart-like structure.

Dart Impact Tester is designed as per international standards. The device has a hemispherical-shaped head or dart which is held using electromagnetic section. The dropping height can be adjusted as per your requirement. The test is performed by keeping the record for the falling cycles with an inbuilt digital counter. The dart machine comes in two different head sizes that can perform dart drop tests for both Method A and Method B. The instrument complies with quality standards such as ASTM and ISO.

Testing the Limits: How to Measure Edge-Wise Compressive Strength of Boxes with the Edge Crush Tester

Image
Measuring the edge-wise compressive strength of boxes is crucial to assess their ability to withstand vertical loads during storage and transportation. The Edge Crush Test (ECT) is a common method used to determine this strength. Here's a step-by-step guide on how to measure edge-wise compressive strength using an Edge Crush Tester: Preparation: Ensure the Edge Crush Tester is calibrated and in good working condition. Verify that the test method complies with relevant standards (e.g., ASTM D642 for ECT). Prepare the sample boxes, making sure they represent the intended packaging materials and have the same dimensions. Sample Preparation: Cut Representative Samples: Cut samples from the box material, preferably from different parts of the box, to ensure representativeness. Standardize Sample Size: Cut the samples to the required size, typically a rectangular shape with specific dimensions. Testing Procedure: Set up the Edge Crush Tester : Follow the manufacturer's instructions ...
