Leak Detection Systems

Empty plastic containers are manufactured in high volume to keep up with demands. It is inevitable that some containers will have defects that will cause leaks once the bottles are filled and shipped. Inline leak testing equipment tests plastic bottles as they move through the production line and automatically reject those with defects.

By performing empty container leak testing – you can identify issues before bottles make it further down the production line, minimizing the potential of recalls associated with bottle quality.

Leak detection systems include pressure decay and vacuum testing equipment used to find leaks and other defects in plastic bottles and containers. Several industries ranging from food and beverage to automotive utilize leak testing equipment to identify defects and ensure product integrity.

Bottle Leak Detection Equipment for PET Containers and More

PET is used to produce plastic bottles for food and beverages, personal care products and household products. Companies prefer this material because is strong, lightweight, does not react with food or beverages and is recyclable. Despite their durability, PET bottles and other containers can have manufacturing defects that lead to product leaks or contamination once the bottles are filled.

Bottle leak detection equipment provides a solution by quickly and effectively testing bottles for leaks and removing defective bottles from the production line. Leak detection systems can inspect up to several thousand bottles per hour, ranging from small vials to gallon-sized containers.

Leak Detection Systems for Automated Bottling and Packaging Applications

ALPS offers standard leak detection equipment for the plastic packaging market, including:

  • Rotary Leak Detection Equipment: Our rotary leak testers feature a rotary configuration and conduct high-speed testing with excellent accuracy. They are designed for on-line inspection and are offered in options for empty plastic bottles, filled and sealed products, extra-large containers, and turrets for Monoblock applications.
  • Linear Leak Detection Equipment: We offer a diverse line of single station and multi-station linear leak detectors for on-line and off-line testing applications. Options include moving head leak testers and conveyor leak testers in several configurations.
  • Integrated Leak Detection Equipment: For customers that don’t need a full leak detection system, we offer leak testing units that integrate within other equipment including bottle converters, labelers, trimmers, blow molding machines and more. All units are built to your specifications to ensure compatibility with existing equipment.
  • Leak Detection System Accessories: Our accessories for leak detection equipment allow you to further customize your system and make modifications as your needs change. Current options include vacuum blowers for bottle handling, downed bottle ejectors and open conveyor chains.

*Final machine speeds are dependent on the test time required to meet the specified leak test sensitivity. Speeds on linear leak testing equipment are also dependent on the container size, with only the smallest products testing on the high side of the speed range.

**Note that these are general size guidelines on standard leak testing equipment only, and machine versions may be available for smaller or larger product.
