Avient Corporation has created an oxygen scavenging additive that claims to extend the shelf life of products packed in PET and rPET bottles without impacting their recyclability.
ColorMatrix Amosorb 4020L is a non-nylon-based additive designed for compatibility with up to 100% recycled material in a PET bottle application. As such, it is recommended for brands with an aim to increase the amount of recyclate in their packaging.
It is designed to extend the shelf life of condiments, sauces, juices, beverages (including certain alcoholic drinks), and other applications in a variety of dosage levels. According to Avient, it complies with regulatory requirements for food contact and product safety in major markets.
At the same time, the coating is said to achieve ‘outstanding’ recyclability and provide an ‘attractive’ aesthetic appeal to the bottles it is applied to.
“We are thrilled to introduce ColorMatrix Amosorb 4020L to the market,” said Dr. Antonello Decortes, global product manager at Avient Corporation. “This new additive technology represents a significant advancement in our commitment to offer extended protection against food spoilage in PET bottle applications.
“By also providing exceptional bottle clarity and recyclability, we are helping our customers meet market expectations and achieve their sustainability goals while reducing environmental impact.”
Towards the beginning of 2024, UBQ Materials revealed three biobased material replacements and additives and two modifiers as part of its Sustainability Product Portfolio. One of them was UBQ ClimaPos, a biobased additive designed to unlock greenhouse gas removal and avoidance.
Incorporating only 5% of the additive into a product is believed to make the material carbon neutral. It has reportedly been proven for use in planters, pet carriers, transport boxes, and window profiles.
Tosaf also aimed to unlock PFAS-free, certified food-safe plastic films with its EFSA- and FDA-compliant additives for the extrusion of fluoroelastomer-free polyolefins. Its AP9709PE EU additive is designed to improve the rheological properties of a pack, while AP9711PE EU enhances clarity, haze, and other visual features.
More recently, a biobased additive from Labelmaster’s DGeo packaging division and Altor Solutions subsidiary Lifoam Industries has been applied to temperature-controlled expanded polystyrene impact packaging. The pack is then expected to biodegrade by 92% within four years without leaching microplastics.
