Filtec
Empty PET Container Inspection

Catch imperfections in PET containers of all sizes before they reach the filler.

EMPTY PET CONTAINER IMPERFECTIONS

Imperfections in empty PET containers, either returnable or straight from the molder, can result in damaged or wasted product.


COMMON REFPET FLAWS

  • Damaged thread
  • Uneven finish
  • Foreign objects
  • Residual liquid or caustic

OUTER SIDEWALL INSPECTION

Outer sidewall refers to the outside surface of a container, usually below the thread and above the base. This outer surface can often become visibly scuffed or chipped, especially in REFPET, sometimes so badly these damages may result in leaks.

Inspection Technology Overview

  • 15 independent inspection zones
  • ACL detection
  • Adjustable illumination
  • 360 degree outer surface inspection
  • 6000k LED panel strobe
  • Cellophane / brightfield detection
  • Adjustable illumination
  • High resolution images

Sidewall Bottle Rotator

Twelve images are captured at 30 degree intervals while the bottles rotate past the inspection window, providing the most thorough inspection and fewest number of false rejects.

Bottles rotate against each other as they pass through the inspection field, allowing for 360 degree detection.
Adjustable LED strobe allows for the illumination of bottle features for easy flaw detection.

BASE INSPECTION

The base of a REFPET container is usually highly featured and therefore more susceptible to cracks and foreign objects that were not removed during the washing process. A base strobe and separate camera focus on this complex area to ensure defective containers do not reach the filler.

Inspection Technology Overview

  • High resolution CCD camera
  • Detection of flaws both inside and outside of the container
  • Adjustable filters for embossing and varying bottle designs
  • Up to 6 different inspection zones
  • Adjustable filters for embossing and varying bottle designs
  • Cellophane / brightfield detection
BASE INSPECTION

INNER SIDEWALL INSPECTION

The bottle's inner sidewall includes all the inside surfaces of the container from the base up through the neck. Damages on these surfaces can be difficult to see, but can easily grow mold or develop cracks after the container has been filled.

Inspection Technology Overview

  • High resolution CCD camera
  • Up to 6 different inspection zones
INNER SIDEWALL INSPECTION

THREAD INSPECTION

A bottle's thread is the molding at the top of the neck where the cap is screwed in place. Damaged thread can prevent the container from sealing properly, threatening pressurized or perishable product.

SYSTEM OVERVIEW

  • High resolution CCD camera
  • Customized acceptable Press, Roll and Twist finishes
  • Five (5) inspection zones plus auto-centering and auto-tracking functions
  • Unique optical system
  • Long-life LED strobe
  • Up to 720 degree inspection of roll thread containers
  • Twist thread inspection (optional)

RESIDUAL LIQUID AND FOREIGN OBJECT INSPECTION

Without additional inspection, leftover caustic can occasionally remain inside of REFPET containers and contaminate the final product. FILTEC uses both radio frequency and infrared detection technologies to inspect REFPET containers for residual caustic.

PARALLEL USE OF IR and RF SYSTEMS

Radio Frequency (RF) RLD Technology

Detects smallest amounts of caustic, even once it has dried

Infrared (IR) RLD Technology

Detects oil, paint, gasoline, and other liquids with low conductivity
