These are additives used in the production of packaging

There are an infinite number of materials and types of packaging, and there is great variety accessories which can be used in its preparation. Therefore, they are usually classified based on the function they play in the manufacturing process or in the final product.

Bad types of additives used in packaging most often these are the following:

  • Anti static. Additives that make the obtained material insulating from electricity. In this way, it reduces its conductive qualities.
  • Antioxidants. They prevent the oxidation of polymers when exposed to weather conditions.
  • Loads.Solid materials added to make the final product more stable, reducing costs in the process. They can be mineral fillers or reinforcing fibers.
  • Drivers. Additives that make the resulting material easier to conduct current, reducing its insulating quality.
  • Sparkling wines. Additives that swell the polymer giving it a foam-like texture.
  • Stabilizers. They slow down the process of plastic decomposition.
  • Lubricants. They reduce the wear of parts when they rub against each other.
  • Fire retardants. They reduce the flammability of the material.
  • Plasticizers. They increase resistance to the natural impact of plastic.

Color has not only an aesthetic function, but also helps consumers distinguish the type of product the package contains.

A very widespread way of coloring plastic packaging is by using it paint concentrates or masterbatches. These types of formulas present pigments in high concentrationso that a small amount enables efficient, even coloring of the product.

Various masterbatches not only include colored in its composition, but also dr additives that give different finishes to the final container

Pigments, dyes and dyes are used in the composition of the packaging in a percentage of 0.5 to 2%. Which makes it possible to change its appearance without changing its chemical composition or properties.

Additives in general and pigments in particular must meet strict regulations to be considered suitable for use in packaging. Mainly when they are focused on sectors such as food.
