Spoken Language: English Category: Sustainable Packaging Although the issue of CFCs in aerosol products is long gone, aerosols do not really have an environmentally friendly reputation in the public mind. But aerosols can also be sustainable! There are numerous ways to make a spray sustainable and environmentally friendly, both in the packaging and in the formulations. We show ways in which aerosols can do without any hydrocarbon gases and fully meet consumer expectations.

Spoken Language: English Category: Sustainable Packaging Molecular modeling has historically been viewed as a research tool with little connection back to commercial products. Computational power, expertise, precise knowledge of chemical space, along with mismanaged expectations has limited the impact of molecular modeling in industrial settings until recently. With advances in physics-based simulation methods and machine learning, molecular simulation is quickly becoming routine alongside experimentation. In this talk, the utility of modeling to develop new products, rationalize product (mis)behavior, and understand how modeling can empower researchers to drive innovation will be highlighted. Case studies will be discussed that illustrate how modeling, when correctly applied, can provide novel insight into design and selection of surfactant based formulations and interactions with packaging.

Spoken Language: German Category: Sustainable Packaging Fast time-to-market, more flexibility with low risk for new designs and product variations. More customer engagement through customisation and quick reaction to market changes. These are just three of the many benefits and added values that arise from digital print packaging. Real-life examples will be used to present ideas, value propositions, implementation and results from digital print packaging projects.

Spoken Language: German Category: Sustainable Packaging The Werner & Mertz Recyclate-Initiative is the pioneering umbrella project for sustainable packaging concepts for home and personal care products. Started more than 10 years ago the foundation was bulit by consequent usage of recycled plastic materials. Believing in the Cradle-to-Cradle® product design for end consumer products Werner & Mertz supported the circularity principle by application of almost unused waste streams especially plastics from household waste collection. Many fundamental projects derrived from this idea. Around the application of recycled plastics Werner & Mertz took care of the quality of mechanical recycled plastic itself. Therefore, different industrial and university development cooperations where established on the so called innovation platform for material sciences (polymers, additives), printing inks, adhesives and recycling processes.

Spoken Language: English Category: Sustainable Packaging Essential oil-based nanoemulsions have garnered significant attention in the past few decades in the field of nanomedicine, food, and agriculture. However, they suffer from major shortcomings such as ageing (Ostwald ripening, coalescence), leakage of the encapsulated agent over time, burst release, or rapid degradation under harsh environmental conditions (pH and temperature change). Moreover, controlling the release of the encapsulated agent from the nanoemulsion matrix is a tedious task. Coating the surface of the nanoemulsion droplet with some low-cost and biocompatible material like silica (US-FDA-approved food additive) can enhance the nanoemulsion performance and can prevent premature degradation of the encapsulated agent. Moreover, silica-coated nanoemulsion can open up the window for functionalization of nanoemulsion to tune the release of encapsulated agents. In this work, we fabricated eugenol nanoemulsions via the ultrasonication method using a mixed surfactant system of a Tween 20 and Dodecyltrimethylammonium bromide (DTAB). Obtained nanoemulsions were stable with droplet size < 100 nm and zeta potential of ~-40 mV. The effect of coating the nanoemulsion surface with silica using different silica precursors was then studied. The effect of ageing time on the thickness of silica shells under different pH conditions was investigated using FESEM and SAXS. A comparison between non-coated and silica-coated nanoemulsions in terms of encapsulation efficiency, sustained-release, stability against different pH, temperature, and storage conditions was drawn. Results obtained from the investigation may have invaluable implications for the fabrication of such silica-coated formulations in the agri-food and cosmeceutical products.

Spoken Language: German Category: Sustainable Packaging The application presented deals with the determination of the adhesive strength of metal-coated polymers using the example of lids for perfume bottles and cream jars. On the one hand, gold or silver-colored coatings must be opaque and abrasion-resistant, and on the other hand they must be as thin as possible for economic reasons. The measuring principle of CAT technology (Centrifugal Adhesion Testing) is used. It can be described as an automatic determination of the strength of up to eight specimens to be tested simultaneously. Due to the rotation of a rotor, the centrifugal force acts on the test specimens located in the rotor. This is used as a test force. Increasing the rotor speed increases this force. As soon as the maximum load capacity of a test specimen is reached, the test stamp separates from the substrate. The detachment event is recorded online and transmitted in real time via a position-based signal to a stationary receiver, which sends the information to the SEPView 7 measurement and evaluation software. The breaking force is automatically calculated based on the mass of the test stamp m, the distance to the axis of rotation r and the critical speed n and is currently displayed on the measuring PC. In addition to the tensile stress, in which the force acts perpendicular to the plane of the adhesive layer, shear strength can also be determined by using specially designed test specimens. The tested sample systems included lids for packaging of cosmetic products from two different production stages (""Red"" -intermediate product stage; ""Blue"" - complete layer system). The primary aim of the experiment was to find out whether layer delamination occurs and to what extent additional layers of the multilayer system affect the surface properties. The determined strengths and exemplary fracture patterns are discussed.

The presentation gives an overview of the different emission scopes along the supply chain and through which factors the packaging design has an impact on the carbon footprint. Finally, a practical example shows how a simple change of an industrial packaging could save money and GHG emissions.

Spoken Language: German Category: Sustainable Packaging The use of post-consumer recycled plastics for packaging materials is a crucial part of a sustainable circular economy to fulfil the targets of the European Green Deal. Up to now there are no standards for cleaning procedures, quality targets or maximum acceptable levels of contaminations which certain chemicals for post-consumer recyclates. The European Consortium CosPaTox aimed to establish such requirements and to create a guideline for manufacturer and converter of post-consumer recyclates as well as for brand owners of the cosmetic and detergents industry. This presentation shall explain goals and tasks of the Consortium, the current state of the work in different work packages as well as the upcoming further steps and highlight some of the results which are already available and likely to become part of the final guideline.

Spoken Language: English Category: Sustainable Packaging The continuing development of legal conditions and frameworks towards a clear reduction of plastic materials in short life cycles currently leads to increased orientation on fiber-based materials as an alternative solution. The central challenge for the extended use of such materials is the 3D forming technology especially when primary packaging is addressed. Furthermore, the interdependency of such materials from environmental conditions needs to be attended. The presentation aims to give a summary about on the current state of science and technology to 3D-forming of fiber-based materials and the corresponding application potential arising from newer developments. Basic material properties such as pore volume, fiber-to-fiber mobility, compressibility and moisture-temperature properties are discussed with regard to the main deformation mechanisms in the forming process. It is shown how material development towards improved strength, extensibility, or bending stiffness can contribute to improve limitations in forming processes. Furthermore, the effect of deviations in material properties is discussed with special focus on frictional properties of fibers in contact with metal surfaces. In addition, the presentation shows new development directions of the processes such as 3D-forming using elevated moisture, the advanced drying through tailored heat transfer zones in forming tools and the agile moisture management combined to this tool technology. Together with an introduction of thermoforming technology features for a deformation of thin membranes in combination with fiber-based shapes, the presentation gives an overview to chances and limitations of packaging production from paper and board in the field of primary packaging.
