The modern market is simply filled with plastic products that differ not only in shape but also in color. Colored plastic is a fairly popular material in many industries, especially in food. Plastic containers of different colors are ideal for transporting and storing food.
But, special requirements are set for such containers. All materials used for their production must be safe for human health and the environment. The same applies to dyes that are used to obtain plastic containers of the desired color.
What pigments are used to color polymers?
Such materials have certain properties that are taken into account in the staining process. To achieve the highest quality result, manufacturers of plastic containers and other products in Ukraine use several types of dyes. All of them are divided into 2 main groups:
The first group of dyes includes calcium carbonate, chromium pigments, titanium dioxide, ultramarine, cobalt, and cadmium substances. Organic substances are substances with complex organic molecules. Vivid examples are phthalocyanine and polycyclic pigments, azo pigments, etc.
More stringent requirements are set for polymer products used in the food industry. Therefore, plastic food containers are dyed with harmless dyes that do not emit toxic substances.
What dyes are used for food-grade plastic?
Products made from this material may only be dyed with special organic food dyes. These are natural ingredients that are obtained from substances of animal and vegetable origin.
The following features characterize them:
Insolubility in the medium to be painted;
Rich and pure color;
The possibility of obtaining a translucent shade.
For plastic, such pigments will be the best solution. Unlike inorganic pigments, they have a wider range of colors and brighter shades. In addition, organic materials have a higher level of light, heat, and weather resistance.
What are the types of organic dyes?
The group of these substances combines 2 types of pigments:
The first option is practically not used in the production of plastic containers, since synthetic dyes are more durable and provide rich shades. For food plastic, coloring compositions are used, presented in the form of super concentrates. They are a dispersion of pigment in a substance that is completely compatible with the polymer.
The prefix “super” means 90 percent of the coloring matter. Along with them, conventional concentrates with 20% pigment content can also be used. More profitable and convenient to use are masterbatches that provide less consumption.
What food colors does PrimeBox use?
In the process of producing plastic for food purposes, we use only high-quality organic dyes. Thanks to their use, we can ensure the production of buckets of various shades for different purposes.
In addition, plastic containers for products with decorative effects are available to order. You can place an order for buckets in bulk by phone or electronically on the website. Delivery of plastic products is carried out in Kropyvnytskyi, Uman, Yaremche, and other cities of Ukraine.
