Daily life exposition to different sources of UV Light: while the sun is our primary natural source of UV radiation, artificial light sources may also incur into unique hazardousness, according to its wavelength range of the emitted UV radiation.


The sun emits electromagnetic radiation of different energy according to its wavelengths Ultraviolet (UV) radiation is defined as that portion of the electromagnetic spectrum between X rays and visible light. 
Some of the radiation, such as that making up the colours of the rainbow, is visible by humans while the part of radiation beyond the violet end of visible light is called UV radiation and can not be seen by humans eyes.


The UV spectrum is divided into: 
• Vacuum UV (40-190 nm);
• Far UV (190-220 nm);vlt 
• UVC (220-290 nm);
• UVB (290-320) and
• UVA (320-400 nm)

Effects of the UV radiation can be either positive or negative to humans and our ecosystem, according to the World Health Organization:

Positive

  • plus
    Are necessary for our body to produce vitamin D, a substance that helps strengthen bones and safeguards against diseases
as lowering the risk of getting some kinds of internal cancer,
like colon cancer
  • plus
    UV rays are also used in various commercial functions, such
as disinfecting fish tanks or sterilizing medical equipment
  • plus
    Ultraviolet rays have their place in our ecosystem
  • plus
    Animal life makes their own use of these wavelengths
too – certain animals can actually see ultraviolet light, and use
it to their advantage, while bees use the reflection of UV off
of flower petals to guide their pollen collecting
  • plus
    Pest Control – Insects are attracted to the UV light and killed
by the electric shock in bug zappers
  • plus
    Picking out counterfeit banknotes – Genuine banknotes have fluorescent marks that are visible only under ultraviolet light

Negative

  • minus
    Effects on the environment is considered the largest problem caused by UV radiation due to the depletion of the ozone layer. Even though some species respond positively, extensive tests in several countries have shown that hundreds of species of plants and animals display negative effects from an increase in UV radiation
  • minus
    Natural UV light reaches the planet surface and can be just
as harmful as some artificial light sources that also contain
UV radiation levels
  • minus
    As humans, we are exposed to different sources of UV radiation and so are the products we use in our daily lives. Excessive exposure to UV radiation from the sun may cause painful sunburns, wrinkling and premature ageing of the skin as well as increase the risk of skin cancers and cataracts
  • minus
    Many polymers used in plastic consumer products are degradable by UV radiation.  When exposed to sunlight
for a prolonged period, discoloration or even cracking
of the polymer chain may occur

UV absorbance is strongly dependent on the thickness of the application and the concentration of UV absorber in the masterbatch dosed.

The wavelength range that is to be blocked by the UV masterbatch is dependent on the UV absorption of the ingredients that need UV protection.

Several known additional benefits performance of the goods are sensitive to UV radiation and therefore need protection 

Some packaged products need content protection against the negative effects of UV radiation:

  • 8
    Aesthetic - Keep the product´s shelf appeal attractive preventing loss of color and yellowing
  • safety-first
    Safety - Keep the product safe for consumer use, specially preventing food and drugs from deteriorating
  • 1
    Function - Keep the product ‘s performance claim and brand values
  • besteck
    Flavor - Keep the integrity of the product´s organoleptic features, preventing loss of freshness and/or changing its flavor
