New DuPont Lidding Sealant Makes Ready Meals Even Easier

30.06.2008
DuPont™ Appeel® with Antifog (AF) Additive Adds Transparency to Lidding

Microwavable dinners just became more convenient with the new DuPont™ Appeel® Lidding Sealant Resins and DuPont™ Appeel® AF. This topical surfactant solution carries an active anti-fogging agent that can be applied to a wide-range of peelable and non-peelable sealant films for products such as fresh produce and Home Meal Replacements (HMR).

DuPont™ Appeel® lidding sealant resins, combined with DuPont™ Appeel® AF (Antifog), prevent lidding films from losing their transparency.
A: lidding film (e. g.: PET, PP, PS)
B: Appeel® plus Appeel® AF
C: substrate (e. g. PET-A, PET-C, PP, etc.)

Anti-fog enhances the overall clarity of lidding and allows the consumer to have a window into a product, which helps curb concerns over freshness of refrigerated and single serving products.

Appeel® lidding sealant resins are designed to provide controlled adhesion to various container substrates (no cutting required), and can be combined with a variety of other films and resins to create an easy peel lidding structure that will resist tearing upon removal of the lid. Offering superior heat seal integrity at ambient and refrigerated conditions and unique self-venting characteristics, Appeel® lidding sealant resins combined with Appeel® AF provide a hermetically sealed package that is easy to open but maintains seal integrity through distribution and retail. In addition, this product combination offers the safety and security of a hermetically sealed package, as well as excellent puncture and tear resistance – meaning there’s no need for a box or additional packaging.

“DuPont packaging science is dedicated to innovation that addresses consumer desires for a hassle-free and healthy lifestyle,” said Terrance Kendig, senior market development specialist for DuPont Packaging & Industrial Polymers. “With today’s on-the-go society, consumers demand convenient packaging that allows them to spend less time preparing a meal and more time enjoying it.”

Appeel® AF joins a long line of DuPont anti-fog products and clear lidding materials that work to increase package transparency and esthetics at the retail level. Furthermore, anti-fog agents prevent fog formation on the surface of the film by altering the physical conditions that lead to fog. This is achieved by causing the condensed water to spread into a continuous film across the inner surface and offset the surface tension of water.

Appeel® lidding sealant resins combined with Appeel® AF provide a wide heat sealing temperature window, allowing for an easier and more forgiving packaging process. Appeel® AF is specifically designed to work in combination with Appeel® lidding sealant resins but can be applied to a wide range of peelable and non-peelable sealant films useful in packaging found in the marketplace. Appeel® lidding sealant resins in combination with Appeel® AF will not degrade seal integrity when applied under the correct conditions in most cases. Typical container substrates for effective use are PP (polypropylene), HIPS (high impact polystyrene), PVC (poly vinyl chloride) and forms of polyester such as APET, CPET and PETG.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
