PET bottle manufacturing and color measurement
by Hunter Associates Laboratory Inc.
The plastic bottle industry has many producers, each striving to manufacture high-quality products. Properties such as barrier characteristics, dimensional stability, shape and appearance are significant. Appearance attributes can include reflected color, transmitted color, yellowness and haze. This white paper from Hunter Associates Laboratory Inc. will discuss general principles behind color measurement instruments and how they apply to pellets, preforms, plastic bottles and caps.
The white paper also discusses the difference between the two basic types of color measurement instruments, tristimulus colorimeters and colorimetric spectrophotometers, which are both categorized as psychophysical measurement instruments, meaning they are designed to give measurements that correlate with human eye-brain impressions.
