Understanding Strength of PET Bottles with Top Load Tester

In today’s times. The PET bottles have grabbed a large portion of industries where they are used for packaging of a variety of products such as food items, aerated drinks, pharmaceutical products and medicines. The reason why the PET bottles have been preferred over glass bottles is that they offer more strength, better usability and easy handling of the products. Additionally, the PET bottles are non-reactive to the chemicals and do not release any harmful chemicals when comes in contact with other products and hence are safe for products like food items and chemical products. Also they are very cost effective as compared to glass bottles as well.

Now when we are talking about PET bottles as a more preferred option for packaging of some critical products then, it is important to understand that the quality of the PET bottles has a great role in keeping the products inside them safe and protected during their transportation and storage. When the PET bottles are stored or transported, they are stacked in the form of pallets and this causes an application of top load compressive forces in the lower layers of the pallets. If the bottles are not strong enough, it can cause the bottles to deform, damage or even explode leading to the damage to the products. This is why the manufacturers of the PET bottles must ensure that the PET bottles they deliver to the clients have enough strength to survive the stacking and buckling loads that may be exerted on them during their use. The shape of a PET bottle describes that it can contain 0.5L of drinkable liquid. Performing a top load analysis is important to determine the vertical stiffness of the bottle. This top load is important to determine the vertical stackability.

The crushing load goes beyond the top load simulation and continues the calculation where the top load stops. The top load analysis displays the force versus displacement graph and at the point the force reduces and the analysis stops.

PET bottles are of five types i.e. water bottles, Carbonated Soft Drinks, Aseptic bottles, beer bottles, and hot fill bottles. There are various performance testing requirements from distinct PET bottles. Due to transportation and stacking, the vertical pressure of the PET bottle compressed by an axial load is a must. The vertical pressure is the most important part to contribute to the failure of PET bottles. Digital Top Load tester are used to test the top load pressure of PET bottles.

The vertical pressure of the PET bottle is the maximum load at the load-displacement curve that is obtained by the vertical compression test. Plastic bottles are sensitive to externally and internally applied loads as their walls are not that strong. Bottle structure and plastic distribution are the two main influencing factors on the vertical pressure of the PET bottle with respect to a lot of tests and production practices. The most focused test process in the Bottle packaging industry is the Top Load testing of PET bottles. The bottles due to its demand in various industries for packaging products experience the top load issue. So, it is a vital test to be performed on the bottle’s resistance capability against prolonging buckling load to check quality control.

Top Load Tester for PET Bottles is a hi-tech machine offered by Pacorr that is utilised in several industries to evaluate strength properties of PET bottles. It is a generation-next model with accurate digital controls and rigid construction. The high grade material used for fabrication of the instruments makes it capable of surviving for a longer time in a harsh working environment in industries without compromising its accuracy and precision. The semi-automation process is delivered in the motorised tester.It measures the resistance strength against compressive buckling load on PET bottles and containers.

Top Load Tester Blogs are written to help the customers get further knowledge regarding the instrument and the usages. The Top Load Tester offered by Pacorr is equipped with high-end digital control having high resolution display screen where the user can see the test value during the test process. The digital control has Automated Tare and Peak hold facility. For placing the sample, there are inverted flat plates for sample hold support.
