Bottles should be tested for top load strength to ensure that they can withstand the pressure and weight that they will experience during transport and storage. Top load strength testing involves applying weight or force to the top of a bottle to measure its ability to resist deformation or collapse. This quality test is critical for ensuring that the bottles can withstand the rigors of transportation and storage without breaking, leaking, or becoming deformed. 

If bottles are not tested for top load strength, they may fail during transport or storage, leading to product loss, contamination, and potential safety hazards. A failed bottle could also lead to costly product recalls, damage to brand reputation, and potential legal liabilities. Thus, we at Presto have designed a high-quality lab testing instrument known as a top load tester, a computerized model that is used to test the top load strength of PET bottles and ensures that quality materials will be delivered to the customers.

This new generation top load testing instrument will give the compressive buckling load in digital format. The bottle needs to be placed in between the inverted concave jaws for zero slip gripping. In this blog, we are going to provide you with the information about Presto Digital Top Load Tester and how this quality lab testing instrument is used to test the top load strength of PET bottles and ensures that quality materials will be delivered to the customers. So, let us get started!

What is top load strength testing?

Top load strength testing is a quality testing method used to measure the amount of weight or force that PET bottles can bear before they deform, crack or break. This quality test applies pressure on the top surface of the bottle and records the maximum point at which it collapses under a specific load.

The top load test is critical because it determines how much weight PET bottles can withstand during transportation, storage, and handling without being damaged. The higher the top load strength value, the more durable and reliable these bottles are for commercial use.

Presto top load testing machine is commonly used to carry out this type of test by simulating real-life conditions that may cause damage to bottled products during transport. This testing instrument applies pressure gradually until they reach a predetermined point where deformation occurs.

You can also ensure compression resistance of PET bottles against top load, with Presto top load strength tester.

Presto is a leading top load testing instrument manufacturer and offers this quality testing instrument at the best price. Now, let us discuss a brief about Presto top load tester digital cum computerized model.
