Top 5 Things You Need to Know About Measuring the Colour of Transparent Plastic Preforms

Transparency plays a significant role in the usability, viability, and overall quality of plastic preforms. Plastic preforms are commonly used for packaging beverages, edible oils, cosmetics, carbonated and non-carbonated drinks, and detergents. Read on to learn how HunterLab can facilitate the correct colour measurement of transparent plastic preforms with spectrophotometers.

Why You Need to Measure the Colour of Transparent Plastic Preforms

Plastic preforms are typically used to manufacture packaging for products that require visibility for the buyers, hence the need to ensure transparency. But why the need to measure it? Here are five reasons:

1. To determine quality: Transparency determines the overall quality of plastics. In most cases, buyers may deem clear, transparent plastics as better quality than hazy, less transparent products.
2. To obtain the right colour: Preforms are prepared during the injection molding process, which precedes the blow molding procedure that creates the final output. Measuring the colour of transparent preforms helps manufacturers obtain the correct colour using spectral data and analysis.
3. To meet industry standards: Different industries follow set standards in product manufacturing, including creating product packaging. Correct colour measurement ensures compliance with industry standards.
4. To create consistent branding: Packaging is part of a product's branding, and ensuring it remains consistent is vital. Spectrophotometers accurately determine the resulting colour of transparent plastic preforms after final production.
5. To ensure zero defects: High-quality transparent preforms eliminate the possibility of colour-related defects in the final product.
