The PreTemp temperature probe from PTI helps provide brand owners and suppliers with a tool to improve PET bottle production and energy costs.

Holland, OH—Suppliers and brand owners who manufacture reheat stretch blow molded polyethylene terephthalate (PET) bottles now have a new tool to assist in producing better containers and improve energy cost management.

Plastic Technologies, Inc. (PTI), a global leader in PET package development, has developed a first-of-its-kind, hand-held temperature probe for preforms that are used to produce bottles. With an increasing number of food, beverage, cosmetic, personal care, household chemical, etc., brand owners bringing PET bottle production in house, this tool will be an asset to improving their bottle-making efficiency.

PTI’s PreTemp probe has been engineered to accurately measure the preform’s interior temperature.

This is an important new capability because traditional methodologies only measure the exterior temperature. The probe also can be used to identify process changes during routine operation and troubleshoot heat-related issues.


“Typically, an educated guess is made regarding the interior temperature, which makes it difficult to effectively control the heat that is driven through the preform wall. This has a profound impact on the manufacturing process including poor thickness distribution, less than optimum bottle performance and wasted energy,” says PTI director of marketing and new business development Ron Puvak.

With the information provided by the PTI PreTemp probe, the user can adjust the heating lamps to more effectively drive heat through the preform wall, improving the final output.

The probe utilizes an array of precision non-contact infrared sensors which provide a temperature profile to the operator. It can be used to measure and record up to 16 data points simultaneously.

This feature allows measurements in both an axial and radial profile thus better assisting in process checks.

The PreTemp probe features single-button operation, has a built-in display for quick reference and comes with powerful, user-friendly software to log and analyze data.

Plastic Technologies, Inc. is a global leader for preform and package design, package development, rapid prototyping, pre-production prototyping, and material evaluation engineering for the plastic packaging industry.
