PET or Polyethylene bottles have been the ideal choice for packaging in the beverage industry. Their flexible nature and chemical properties make them the foremost choice for the industry to rely upon. The PET material makes good bottles as it can deliver all the necessary end-user requirements and assures the highest quality. However, a lack of strict inspection and audits can result in passing a poor quality to the consumer and losing brand reputation as a whole. Therefore, it is of vital importance that the PET bottles are tested before they are delivered to the market especially for their top-load strength using a top load tester.
Why do we need to test the top load strength of PET bottles?
PET bottles are furiously used by various sectors and industries for multiple uses. These bottles can be used in households for packaging of drinking water or they may be used as containers for chemicals or they are utilized in commercial beverage industries that produce sweetened dring mixed with pressurized air. All these sectors have one thing in common that is the use of PET material for their packaging need. Although PET bottles have numerous properties that allow them to deliver the maximum efficiency in assuring the packaging need, they must be checked for their quality gaps. One of these faults is the top load strength of bottles.
Any kind of PET bottle of any industry will face two situations for sure. Either they will be stored in the warehouses for long before they are out in the market or they will be stacked in transports for getting them delivered from one place to another. Even in some stores, they are kept in the same position for a long time. In such situations, they encounter vertical load and extreme pressure. Facing these poor quality PET bottles will deflect and get damaged, and better quality products can resist the load for a longer time and get delivered to the end-user in intact form.
Hence, it's important to test the top load strength of bottles before making them available in the market.
How to evaluate the top-load strength of PET bottles?
To evaluate the top load strength of a PET bottle, one needs to recreate the load application on bottles with different amounts of force for different durations.
Top load tester is a user-friendly, digital, tabletop model that allows the manufacturer or product designer the free hand of performing quality tests anywhere anytime, production line or testing lab. The machine is equipped with a variable frequency drive that delivers accurate control in the speed variation. Its Microprocessor-based load indicator on the display screen ensures maximum precision in test value.
The test equipment can automatically record the highest load value that is recorded in the test process. It is equipped with crosshead travel protection along with limit switches for safety measures. It delivers protection in situations like overload, extreme compression or voltage. The machine body is made with a strong structure that assures a high-quality performance for a long time for a variety of weathering conditions. It is painted using powder-coated corrosion-resistant paint to protect against corrosion. It can withstand a load capacity that renegades from 0 to 100 Kgf. The size of compression plates is designed as per set industry standards that are 140 mm x 120 mm. The speed is variable and can be customed as per the industry or client requirement. It delivers an accuracy of ± 0.05% of load and a Resolution of 0.1 Kg. This technology helps to examine the top load strength of any PET bottle with maximum accuracy in test results.
