           PET Packaging for Dairy Industry



PET containers must have distinctive form and color to create product identity and build product recognition on the
store shelves. In addition to the aesthetic reasons for choosing a particular color, functional considerations are of
vital importance: vitamins in dairy products must be protected from the harmful effects of light, and the colors and
additives in the PET container must be homogenously distributed in order to provide maximum protection.




                                  Excellent distribution
                                  Homogenous distribution of the colorant throughout the PET bottle
                                  is an absolute must. Otherwise, both product integrity and aesthetics
                                  will be compromised. Streaks and swirls may appear in the preform,
                                  resulting in high scrap rates during the blowing process, which can lead
                                  to production problems and increased costs.

                                Preserving vitamins
                                Both natural and artificial light can cause the essential vitamins and nutrients to deteriorate in dairy products.
                                Exposure to light can also adversely affect flavor.



                                                      The severity of these effects depends on the composition of the
                                                      dairy product itself, the intensity, duration and wavelength of
                                                      the light. In the UV and visible spectrum the damage is caused
                                                      by wavelengths up to 550 nm, especially between 380 nm and
                                                      550 nm. Since clear PET bottles only offer protection up to
                                                      320nm, light-absorbing additives and protective colors, most
                                                      often titanium dioxide (TiO2 ), are therefore essential.




                     The graph shows the effectiveness of TiO2 for wavelengths above 380 nm.

                                      attractive designs and eye-catching colors.
