Amcor wins Dow packaging award


Amcor’s AmPrima recycle-ready coffee packaging was recognised by the 35th Packaging Innovation Awards, which are sponsored by Dow. “Our AmPrima Plus was the perfect solution for


Nordic coffee leader Kjeldsberg, with whom we won this award. It is a mono-PE pouch that offers a high barrier to prolong the freshness of coffee. It runs seamlessly on coffee roasters’ packing machines and is readily recyclable in most European countries as certified by Institute cyclos-HTP,” said Giorgio Dini, marketing manager EMEA for coffee at Amcor. The package was designed in accordance with the


Circular Economy for Flexible Packaging (CEFLEX) guidelines, and it helps brands move to a mono- material solution that allows for easy recycling.


Blockers and stabilisers Ultraviolet (UV) absorbers or light blocking additives may be used in packaging to protect contents from UV degradation. Conventional UV blockers have included those based on benzotriazoles, but since some phenolic benzotriazoles have been added to the European Chemical’s Agency candidate list of Substances of Very High Concern (SVHC), alternatives that are not on the SVHC list are being considered. Ampacet’s UVBlock 1496 is an alternative that


offers UV barrier performance in the low UVA and UVB wavelength range, the company says. It is approved for food-contact applications in Europe and the US. Agricultural applications, such as films used in


greenhouses, have stringent stabilisation require- ments, because the films must withstand both weathering and the increasing use of inorganic chemicals in agriculture. The latest from BASF is Tinuvin NOR 211 AR, a heat and light stabiliser to protect films used in intensive horticulture under severe UV radiation and the presence of high levels of sulphur and chlorine. These films are being designed for greater durability, which improves sustainability by reducing plastic waste. “The Tinuvin NOR 211 AR additive solution


addresses a broad variety of challenges for agricultural plastics, including sustainability requirements, increased chemical exposure, longer use durations and downgauging trends,” said Bettina Sobotka, head of global marketing and development for plastic additives at BASF. “BASF’s NOR [non-basic aminoether] HALS [hindered amine light stabilisers] solutions improve stabilisa-

tion by moving beyond solutions based on secondary and methylated HALS. Through collabo- ration with agricultural plastic producers as well as farmers, we facilitate the exchange of knowledge and expertise, creating solutions that will ultimately lead to improved crop yield.” The new stabiliser is part of BASF’s Valeras


portfolio, which the company says is designed to help users meet their sustainability goals. Renew- able electricity is used to manufacture the additive, and the product form improves material dosing precision, among other benefits, the company says. Clariant has introduced light stabilisers specifi- cally for agricultural films: Addworks AGC 102G for greenhouse films and Addworks AGC 970G for mulch film applications. Eliandro Felipe, head of sales Americas for additives polymer solutions at Clariant, said that greenhouse films are being designed to last three to five years in the field, with increased UV exposure and increasing use of harsh chemicals. Addworks AGC 102G is used to help prevent premature degradation as well as to reduce haze and maintain film transparency. Techmer PM’s custom UV stabiliser packages for agricultural film are designed to allow films to last in the field for the growing season and retain tensile properties in extreme environments. The company has also designed UV products for compostable films, which are meant to be installed in the field and used for a year, with the additive tailored specifically for a region, growing season length, and film thickness. Depending on the application, UV packages are designed for various environmental exposures, including pesticide chemicals commonly used in the agricultural
