What You Need to Know About the Colour Matching Process for Lotion Pumps, and Trigger Sprayers

How appealing your product looks can be the difference between a customer buying your product or not.

Recent research shows that quality and beautiful packaging has a direct effect on consumers’ buying behaviour. It is a known fact that color naturally plays an important role in influencing buying behaviour.

“According to the finding of the research study, it has been observed that the packaging is the most important factor. It is further concluded that the packaging elements like its Colour, Packaging material, Design of Wrapper and innovation are more important factors when consumers making any buying decision.”

Color can increase brand awareness by 80% and directly affects consumer trust. We understand how important choosing the right colors for the product is.

Bearing this in mind, our  lotion pumps and trigger sprayers come in a variety of colors in order to cater to the different needs of buyers.

Color-matching your trigger sprayer, or lotion pump can make your final product look stunning. Regardless of the packaging material you choose, plastic color matching is one of the main coloring processes used to ensure brand integrity. Because of its low cost and convenient coloring method, it is more common.

This process is used for bottle caps, pump heads, bottles, lipstick tubes and other packaging materials. So, what exactly is the color-matching process, and how does it work?

Let’s take a look!

What is Plastic Color-Matching?

Lotion pump and trigger sprayers are usually made from a plastic material. Plastic materials are made of synthetic resin and fillers, plasticizers, stabilizers, lubricants, pigments and other additives. During the plastic injection molding process, color pigments are added in the raw plastic materials to make them have specific colors or specific optical properties.

The process of adding these pigments which are usually Pantone color-matched is called color matching.

Plastic color matching is determined based on the three basic colors – red, yellow, and blue. To match whatever color that you desire, it must meet the color difference requirements of the (pantone) color card. It must also be economical and should not change color during processing and use.


1. Colorants for Color Matching

The colorants used during the colour matching process are mainly divided into two – pigments and dyes.

Pigments are colorants that cannot be dissolved in common solvents. To obtain the ideal coloring properties, it is necessary to uniformly disperse the pigments in the plastic by means of mechanical heating and mixing. Pigments can be divided into inorganic pigments and organic pigments.

Dyes are mainly pearlescent pigments. Pearlescent pigments are natural or synthetic micas that have been coated with titanium oxide, iron oxide or some other metal oxide. Mica titanium pearlescent pigments are the most commonly used dyes. As we noted earlier, they are mica wafers coated with titanium dioxide. Depending on the hue, it can be divided into three types: silver-white pearlescent pigments, rainbow pearlescent pigments, and colored pearlescent pigments.


1) Inorganic Pigments

Inorganic pigments have a much better thermal stability and very good weather resistance compared to organic pigments. They are also light, are relatively low-priced and have an excellent dispersion performance.

You should choose based on your different needs. For example: titanium dioxide, carbon black, etc.

2) Organic Pigments

These type of pigments have high tinting strength. They are brightly colored, have a complete chromatogram, and have a low relative density (unit: g/cm3 or kg/m3) plus a neglible addition amount.

The main disadvantage of organic pigments is that its heat resistance, weather resistance and hiding quality are not as good as inorganic pigments. Added to this, is the poor dispersion effect, poor transparency relative to dyes, and higher prices.

Organic pigments are mainly used in the production of PE, PP crystal materials and some products with bright colors that cannot be achieved by dyes.



Dyes refer to a class of organic compounds that can make other substances obtain bright and firm colors. Artificially synthesized pigments are also called synthetic dyes. They can be used with most solvents and dyed plastics, with the advantages of low density, high tinting strength and good transparency.

The main disadvantage is that its general molecular structure is small, and it is prone to migration (crystalline material) when it is colored. It is usually is more expensive than inorganic pigments, even though the price of some dyes is somehat closer to that of organic pigments.


Depending on the type of plastic and what it will be used for, the colorant being used should meet these conditions: the heat resistance, light resistance, weather resistance, migration resistance, and safety requirements.


2. Color matching method

The method of adding toner directly to resin and masterbatch method can be used.

After the toner is directly mixed with the plastic resin, it is sent to the next product molding process, which is a short and low-cost procedure. But if the working environment is poor and the coloring power is poor, the coloring uniformity and quality stability of the product will be also be poor.

The color masterbatch method is to formulate the colorant, carrier resin, dispersant, and other auxiliary agents into pellets with a certain concentration of colorant. When the product is molded, a certain amount of color masterbatch is added according to the coloring requirements to make the product contain the required amount of colorant.


Color matching principle

The plastic color matching process is more complicated. In order to achieve the desired effect of color matching, it should be fast, accurate and economical. The following principles should be followed.

1.     The “small amount” principle.

The selection of colorants for plastic color matching should be less. It is easy to bring in complementary colors to make the color darker.

2.     The principle of “closeness”.

For plastic color matching, attention should be paid to the selection of pigments with similar heat resistance and similar properties, if the difference between the properties is too large, changes in production temperature will cause color changes or affect product appearance.

3.     The principle of “complementary color”

It is necessary to prevent the introduction of complementary colors when matching colors, otherwise it will make the original color luminosity dim and affect the brightness of the color.

Complementary colors are also called residual colors. Primary colors other than the two primary colors are usually called complementary colors. For example, orange is a combination of red and yellow, and blue is a complementary color.

We pay close attention to the different shades of pigments when matching colors. For example, carbon black and titanium dioxide for plastics are blue and yellow respectively due to different particle sizes, and the pigments have greater differences in shades. Our highly expereinced employees avoid using complementary shades to match colors, because it reduces the saturation and darkens the final color of the product.

How to Choose Product Color

Choosing the color of your trigger sprayer or lotion pump depends on your product. The following advice on choosing what color these bottle caps should have is for reference purposes only.

In color psychology, white creates the impression, clean, pure, efficient or simple. Products like cleaning pump heads are usually white in color.

Pink is feminine, youthful tones are softer, more passionate and energetic. Pink packaging is usually suitable for products related to the female market, such as cosmetic spray pump heads.

Red represents new, bold, exciting and modern, used to attract attention, such as daily chemical wash pump head.

Yellow is cheerful, optimistic, and a good choice for trigger sprayers to used with cleaning products.

Green represents freshness, full of imagination, and conveys environmentally friendly or organic messages. It is a good fit for garden trigger sprayer products.

Black connotes elegance and maturity. Generally, black caps can be selected for medicinal bottles, and black pump heads are good for any bottle.

Purple is related to lofty ideals, imagination and spirituality, and is more attractive to women and youth markets.

Silver or gold will increase the elegance and novelty of the product. High-end cosmetic pump heads like to use anodized aluminum spray pump heads。

With the development of process technology, the color matching of plastics can be performed more accurately and efficiently through the colorimeter and the computer that processes the data.

We don’t want to bore you with any more technical details on the color matching process here. Packbien’s lotion pump and trigger sprayer products are designed with a superior color matching process with the result being colorful, high-quality and beautiful products. Needless to say, such quality translates to more demand and sales of your product.
