The future of bottle & cap testing Emerging technology & trends

Are you tired of the constant struggle to ensure the quality and safety of your bottles and caps? Do you want to ensure zero product rejection rates, while delivering products to the customers? If yes, then it is important for the manufacturers to test the quality of products before delivering them to the customers. Thus, we at Presto being the leading bottle and cap testing instruments manufacturer has designed high-quality lab testing equipment that will accurately test the quality of your caps and closures and ensure that high-quality products will be delivered to the customers.

In this article, we will focus on the importance of testing bottles & caps before delivery and top high-quality lab testing equipment to test the quality of products efficiently.

Introduction: The Importance of Bottle & Cap Testing

As consumers become more interested in health and sustainability, the bottled water industry has had to make some changes. One of the most important changes has been in the way that bottles and caps are tested.
In the past, most bottled water companies used a standard bottle cap with a hole in the top. This allowed for easy testing of the water inside the bottle. However, this method was not very reliable and often resulted in false positives.
With the introduction of new technology, there are now more accurate ways to test bottles and caps. To make it easy for the PET & Preform manufacturers to test the quality of bottles accurately, we at Presto have designed high-quality lab testing equipment to ensure accuracy in test results.
Below we have listed the top 3 bottle & caps testing instruments that one must use to ensure zero product rejection rates.
