How Do You Check The Top Load Of PET Bottles

PET bottles are nonreactive and capable of carrying potent acidic or reactive agents and materials of similar properties. It is a high-quality polymer that can be subjected to varying degrees of environmental changes. Innovation through new materials and improved packaging contribute significantly towards the sales of products. Top load testing is a crucial test for PET bottles. It is one of the most preferred testing methods for manufacturers and consumers both.

What Is Top Load Testing ?

PET packaging has the properties to withstand various real-time conditions. Once packed, bottles are tested to varying degrees of internal and external pressure. Top load testing is an excellent method to perform quality checks and evaluate the efficiency of the packaging. Top load testing is a standard quality control test conducted on PET bottles to assess their resistance to deformation or collapse when subjected to a vertical load on the top surface of the bottle. Following are some benefits of conducting top load testing on PET bottles.

Benefits Of Conducting Top Load Testing:

• Top load testing helps to ensure that the PET bottles are capable of withstanding the stresses that they may encounter during handling, storage, and transportation. This ensures that the product quality is maintained and the bottle's contents are protected.
• Manufacturers can help identify any weak spots or defects in the PET bottle, allowing for improvements to be made to the design or manufacturing process to increase strength and durability.
• It helps identify defects and weaknesses early in the production process. This can lead to cost savings by preventing the need for recalls or rejections of batches of bottles that fail to meet quality standards.
• Manufacturers can ensure that the PET bottles are strong and durable, improving customer satisfaction by reducing the likelihood of bottles being damaged during transit or storage, leading to a better overall customer experience.
• It is required to comply with various industry standards such as ASTM and ISO. It helps ensures that the PET bottles meet the required standards for quality and safety.

How To Perform Top Load Test

Step 1: Set up the top load tester according to the manufacturer's instructions. The top load tester by Pacorr is a user-friendly tabletop model equipped with a variable frequency drive and microprocessor-based load indication. Adjusting the load cell and test speed.
Step 2: Choose a sample of PET bottles and ensure they are free from any visible defects or damage. Place the bottle on the load tester platform, with the top surface facing upwards and the bottom section facing downwards.
Step 3: Adjust the load to the top surface of the bottle at a specified rate, typically 10 mm/min. The load should be applied until the bottle shows any signs of distortion or reaches its maximum load capacity.
Step 4: Calculate the average top load capacity for the sample PET bottle and compare it to the required capacity or industry standards. The advanced top load tester by Pacorr can automatically record the peak load value of test results.

Final Thoughts
It is a common perception that plastics are far more flexible and convenient compared to glass or metallic packaging. They are comparatively more durable and cost-effective alternatives. However, if the bottles are not subjected to proper load testing, it might lead to damaged products or compromise the quality it packs in. The top load test helps identify defects or manufacturing issues. Pacorr is the best manufacturer if you are looking for load testing equipment for your lab that provides quality results.
