Green Pigments in Packaging: Driving the Sustainability

admin Jan 23, 2026

Color affects how we feel about products by showing freshness, eco-friendliness, and brand identity. As packaging becomes more eco-friendly, every material, including pigments, is being scrutinised more closely.

Green pigments are unique not only because of their color, but also because they help packaging meet environmental goals. Manufacturers want pigments that are safe, stable, and long-lasting.

How do green pigments help make packaging more eco-friendly? Let’s discuss their science, how they work, and how they benefit the environment.

What Are Pigments That Are Green?

When added to packaging materials, green pigments change color to make different shades of green. They can be made of organic or inorganic materials, and the type of material (plastic, paper, foil, etc.) and the desired result will determine which one to use.

Different kinds of green pigments:

• Chromium Oxide Green (Inorganic) o Strong and resistant to UV light; used in plastics and coatings.

• Phthalocyanine Green (Organic): This color is bright and stays the same for flexible packaging and printing inks.

• Alternatives that are good for the environment

Why Green Pigments Are Important for Sustainable Packaging

People have been worried about synthetic pigments for a long time because they contain toxic heavy metals, don’t break down easily, and are hard to recycle. That’s why the pigment business is changing.

Today, “green pigments” means both the color and the fact that the pigments used in packaging are good for the environment. Their benefits for the environment can really make a difference:

1. Better for recycling

Pigments that don’t get in the way of sorting make it easier to recycle packaging.

2. Safe for Food Use

The FDA, FSSAI, or REACH have all approved many green pigments for use in food packaging.

3. Less carbon footprint

Some pigments are made using inputs that can be used over and over again or processes that use less energy.

Uses of Green Pigments in Packaging

Green pigments are used in many different types of packaging where color and compliance are both very important.

1. Flexible Packaging (Plastics, Laminates)

Used in wrappers, pouches, and films to make them look good while still working with low-VOC inks and eco-friendly resins like PLA or recycled polyethylene.

2. Hard packaging (bottles, caps, and containers)

To make colored bottles and caps that can still be recycled, green pigments are added to HDPE, PET, and PP.

3. Packaging that is safe for food

Phthalocyanine-based green pigments are often used in food container printing inks and label coatings to make sure they are safe and the colors stay stable.

4. Packaging made of paper and board

We use eco-friendly green pigments to print on kraft paper bags, cartons, and cardboard trays with water. This is in line with our zero-waste goals.

What Makes a Pigment “Green”?

It’s not just about the color; it’s also about doing the right thing. A real green pigment has to meet a number of standards:

What Criterion Means

Not harmful, doesn’t have heavy metals, VOCs, or cancer-causing chemicals

REACH, RoHS, FDA, and FSSAI certified for compliance with rules

Recyclability works with recycling streams.

Safe to touch. Good for use in food or cosmetics

The Science Behind Pigments: How We Create Lasting Colors

admin Jan 12, 2026

Color influences our emotions and perceptions. The red of a car or the green of a wall can shape how we view our environment. Each color results from a combination of science, chemistry, and creativity, which defines the world of pigments.

Pigments provide vibrant colors, enhance product appeal, and improve durability. In paints, plastics, or food, pigments must retain their appearance over time. To understand their importance, let us define pigments and explain how they function.

What Are Pigments?

Pigments are colored substances that give materials their color. Unlike dyes, which in liquids, pigments are tiny particles that do not dissolve. To color a product, pigments need to be mixed into something like resin, plastic, or liquid:

• Inorganic pigments: Derived from minerals and metal oxides such as iron oxide, titanium dioxide, and chromium oxide. These pigments are highly durable, provide strong light-blocking properties, and resist sunlight damage.

• Organic pigments: Made from carbon-based compounds, these pigments produce vivid colors such as red, blue, and green. They are commonly used in inks, plastics, and coatings. The choice between pigment types depends on color intensity, application, and environmental factors. Next, we will examine how pigments create the colors we see every day

The Science of Color

How do pigments create color?

This occurs because pigments absorb certain wavelengths of light and reflect others.
Pigments work by absorbing some colors of light and reflecting others. The color we see is the light that is reflected from the object.

For example:
• A blue pigment absorbs red and green light but reflects blue.
• A yellow • A yellow pigment absorbs blue light and reflects red. The chemical composition of a pigment determines which wavelengths it absorbs or reflects.

Even minor structural changes can result in different colors. Now that we have covered the science, let’s examine how pigments are produced. pigments take chemical know-how, careful work, and technical skill. While the details can change depending on the pigment, there are usually five main steps:

Pigments are found in countless products, often unnoticed but essential. Here are some of their primary applications:

Synthesis

Pigment synthesis begins with chemical reactions. Inorganic pigments use metal oxides, while organic pigments are derived from petroleum or plant sources. These reactions are carefully managed to produce specific crystal structures, which influence color strength and stability.

After preparation, the pigment mixture is filtered to remove impurities and then washed to ensure purity. The mixture is then heated to form a fine powder. This helps keep its structure and color. Pigments are ground into tiny particles with special machines. Smaller particles help evenly distribute color in paints and plastics. Face treatment enhances performance; pigments are often coated with materials such as silica or alumina. These coatings improve dispersion, increase resistance to sunlight, and enhance compatibility with other chemicals. Next, we will discuss what contributes to pigment durability.

A pigment’s durability depends on several factors. The first is lightfastness, which is how well it resists fading in sunlight.

Lightfastness measures a pigment’s resistance to fading in sunlight. Inorganic pigments typically outperform organic ones, making them suitable for outdoor paints and building materials. Another key factor is heat stability, as pigments must endure high processing temperatures, especially in plastics and powder coatings.

Chemical Resistance
Good pigments resist damage from acids, alkalis, and solvents. This keeps their color consistent in various environments.

Dispersion Quality
When pigments are spread out evenly, the color stays smooth and doesn’t clump, streak, or fade in spots. These factors demonstrate why pigments are important across many industries.

Paints and Coatings
Pigments in paints add color and provide coverage, gloss, and protection against weathering and corrosion.

Construction Materials
Inorganic pigments are used in cement, tiles, and pavers to maintain color stability and protect against sunlight. In food and beverages, pigments such as Tartrazine (Yellow 5) and Brilliant Blue (E133) enhance visual appeal while meeting safety standards.

Plastics and Packaging
Pigments in plastics must withstand high molding temperatures while retaining color brightness.
