DuPont at Interpack 2005: science and technologies for innovative packaging solutions and brand security

Du Pont Engineering Polymers : 03 March, 2005  (Company News)
At Interpack 2005 in D
This year, this offering has been extended to include new technologies and services for brand protection, aimed at the identification and prevention of counterfeit products.

DuPont Packaging Solutions (DPS) reflects the company’s intent to develop innovative and tailor-made packaging solutions by bringing together the expertise and technologies of all its divisions active in the food, medical, cosmetics, personal care and consumer goods markets. “We are committed to finding the most appropriate and cost-effective solution, by focusing our research and development efforts on what really matters to our customers. Over the last two years, DPS has already engaged with over 100 clients across the packaging value chain to bring unique science and technology, improving product quality and differentiation,' says Timothy Kolakowski, Vice-president DuPont Packaging.

DuPont packaging solutions to be presented at Interpack 2005 include:

Security and authentification
DuPont Security & Solutions, a newly created division within DuPont Packaging & Industrial Polymers (P&IP), markets two technologies which provide brand-owners with powerful tools in their ongoing fight against counterfeiting and tampering. Developed by Identif GmbH of Erlangen, Germany, these technologies – Bio-Molecular Fingerprint (covert) and Color Spectra Film (overt) – include human and machine detectable “signatures” that can be integrated into secondary packaging or labelling for many consumer packaged goods.

Packaging films
DuPont Teijin Films offers Mylar® polyester films for trusted film solutions that provide convenience, freshness, and shelf impact. Innovations include clear films with ultra high barrier, food release films, extrusion adhesion films, and thermo-formable and shrink films. In addition, the business has a wide range of films offering superior mechanical strength, temperature resistance, flavour and odour protection, chemical resistance, and broad compliance.

Polymers and modifiers
DuPont polymers and modifiers are established as materials of choice for packaging designers and developers, whether in food, medical, cosmetic or industrial packaging applications. With the aid of innovative technologies, DuPont offers numerous ways of creating differentiated and convenient packaging:

Differentiated peel concepts for bags and pouches. A broad technology platform offering a wide variety of peel concepts for easy opening and perfect sealing on most existing packaging webs in the food and healthcare sectors, including glass, ceramic, polyester and non-wovens. As an example, DuPont Burst-peel, designed specifically for flexible bags, offers true convenience while preserving product flavour and freshness, and delivers excellent graphics.

Surlyn® Thick Wall Bottle (TWB) technology. Based on DuPont Surlyn®, widely known for its exceptional transparency, durability and resistance, TWB technology offers designers a wide range of creative aesthetic effects - including transparency, translucency and opacity, as well as the possibility to layer two or more colours, and opens up new possibilities for producers of luxury packaging.

Active packaging. New active packaging technologies from DuPont help remove unpleasant odours from cereal or poultry packaging, or prevent the development of mould.

Special adhesives and lacquers
DuPont Performance Coatings adhesive products for soft packing for foodstuffs ensure even faster and more economical sealing. Innovations include a new cold applied, solvent-free laminating adhesive system with fast cure and a high-performance laminating adhesive for demanding laminate structures such as barrier coated films. The business has also developed an odourless UV topcoat for both flexpacks and cartons.

Barrier solutions
DuPont Zonyl® and Foraperle® fluorprotectants are a greaseproof treatment for paper and cardboard, providing an effective barrier against all types of grease. Safe, effective, environmentally-friendly products, they are used in a variety of food packaging applications such as frozen products, baked goods, pet food and oil-bottle labels.

Tactile effects
DuPont Elvaloy® “Soft Touch”. A technology that provides soft handle, or other tactile effects, that are becoming increasingly popular among consumer products. Elvaloy® can be used in tubes, trays and films, on carton, and to create glass-like packaging, whether opaque or transparent.

Tyvek® non-wovens are a leader in tough, breathable packaging for medical, industrial and consumer goods. Used in many forms of sterile medical packaging, for example, Tyvek® brand protective material is used for pouches, lidstock, breather patches and headers for bags. The unique structure of Tyvek® delivers an optimum balance of bacteria penetration resistance, tear strength, puncture resistance and a clean peel, as well as compatibility with existing and newer sterilisation methods.

Packaging graphics
DuPont Imaging provides digital solutions that allow the accurate prediction and certification of colour for printed packaging. The business is also developing digital printing systems for production work in packaging, point of purchase and flag or banner applications.

DuPont Cyrel® Flexo printing plates reduce lead times for printed material by 80 percent using the Cyrel® Fast system, which also removes all solvents from production. DuPont Cyrel® also offers ‘gravure’ quality with the latest generation of digital seamless sleeves, maintaining the flexibility of flexo, while further reducing start-up times by eliminating the mounting process.

DuPont Safety Consulting
Bringing the science of safety to the workplace, and the food chain, DuPont Safety Resources helps companies gain significant and sustainable improvement in operating costs, security, productivity, product quality, public image and employee morale. Through its Qualicon subsidiary, DuPont provides powerful, automated, DNA-based diagnostic tools and consulting expertise for protecting food supply and tracking biological agents.

DuPont Packaging Solutions is a venture formed by various business units within DuPont such as Packaging & Industrial Polymers, DuPont Teijin Films (DTF), Imaging Technologies, Nonwovens, Performance Coatings and Chemical Solutions Enterprise (DCSE).
