New Polyolefin Sealant Released by Jindal Films

Posted By ASC, Monday, January 23, 2017

Jindal Films Europe has released its new SealTOUGH technology, a coextruded packaging film that is intended as a replacement for lamination with layers of sealant, or mono-web layers in packaging. The company says that its new product offers puncture resistance and enhanced clarity with improved modulus and seal strength and that the sealant film will allow a 30 to 40 percent reduction in gauge, contributing to reduced materials requirements and costs while remaining recyclable.

 

The company reports that the new packaging film has three times as much tensile strength and twice as much resistance to puncturing and impact as traditional materials. Clarity is as great as that offered by BOPP, but seal strength is as great as that of blown PE reports Jindal.

 

Jindal Films will be relocating its head office to LaGrange, Georgia, and the Georgia production plant is undergoing upgrades to increase its production and product range capacity. These improvements include the addition of orientation, metalizing, coating and slitting capabilities.

BLOG:  Imparting Barrier Properties in Flexible Packaging Applications

 

By Deb Bhattacharjee, Adhesives.org Expert Blogger

 

Each layer in multilayer flexible packaging serves unique property for the benefit in its end use application, esp. for improving the shelf life of the packaged goods. The packaging material needs to be versatile enough to withstand handling process forces maintaining physical integrity, resistance to chemicals, and suitable for barrier properties to several gases (e.g., O2, N2, CO2, moisture vapor). The driver and trends of barrier materials for flexible packaging, including functionalities and global volumes of barrier materials like aluminum foil, PET film, nylon resins, metallized films, PVDC resin, EVOH resin, transparent oxide-coated film, COC (cyclic olefin copolymer) resin, AMAB (acrylonitrile-methyl acrylonitrile copolymer grafted with butadiene) resin, etc. are described in details in the recent article, “Barrier materials for flexible packaging”, Market Focus Research – 2011 to 2015, by Allied Development Corp.


What are the fundamental properties determining the difference in barrier properties?

Barrier properties are correlated to the intrinsic structure of the polymer such as degree of crystallinity, crystalline/amorphous phase ratio, nature of polymer, orientation, thermal and mechanical treatment before and after food contact, polarity of chemical groups present into the polymer, degree of cross-linking, and glass transition temperature. Furthermore, the intrinsic composition of the packed food...READ MORE

Pioneer Adhesive’s Epoxy Clay Used to Mend Coral Reef

Posted By ASC, Tuesday, January 10, 2017

Fixing coral reefs with the help of adhesives may sound strange, but it is a reality. Pioneer Adhesive’s epoxy clay is being used for the job, in which divers affix coral fragments to bare rock in the hope that the living coral will grow and regenerate the threatened coral reef. The fragments are grown in special coral nurseries before being taken out to sea where divers first clean rocks, and then attach the coral using a combination of nails, zip ties and the epoxy clay.

 

The project is sponsored by Pioneer Adhesives Foundation Inc. in cooperation with local government and Pangasinan State University in the Philippines. In a single dive expedition, five teams of divers consisting of five divers per team will plant up to 2,500 coral fragments. Meanwhile, onshore efforts to support the establishment of the coral have been underway with volunteers planting mangroves to prevent sedimentation.

DELO Releases New Flame Retardant Epoxy Resin Adhesive for Aircraft Interiors

Posted By ASC, Wednesday, January 4, 2017

Adhesives for aircraft interiors have to fulfil several requirements, among these, the requirements for fire protection, along with good aesthetic qualities for a neat and attractive finish. DELO’s new DELO-DUOPOX AB8390 two-part epoxy resin has fulfilled fire protection requirements including those for low flammability, smoke density and toxicity. It tolerates temperatures ranging from -55 °C to +85 °C. In addition, the adhesive is highly resistant to unsightly yellowing, maintaining a pure white color in 1,000-hour tests at a humidity level of 85% and a temperature of +70 °C.

 

Easy application is made possible through the DELO-AUTOMIX system, which automatically mixes the two components during application. It cures within 30 minutes, but will cure faster if subjected to temperatures of around 60 °C. According to the company the adhesive will be especially suitable for bonding lightweight sandwich panels. It will be suitable for load-bearing connections as well as ditch and pot applications.

ITW Polymers Releases New Adhesive for Galvanized Metals, Plastics and Composites

Posted By ASC, Tuesday, January 3, 2017

ITW Polymers has released a new adhesive specifically formulated to bond galvanized metals. It is also suitable for bonding dissimilar substrates, and it is able to form strong bonds with engineered plastics and composites. The methacrylate adhesive, Plexus Galvanized Bonder™, can be used as a substitute for mechanical fasteners, providing good bond strength and fatigue endurance as well as sheer, peel and impact resistance.

 

Apart from enhancing production line efficiency thanks to the elimination of the processes needed to join materials with mechanical fasteners, it can perform its function without any need for surface preparation or primer application. Plexus MA8110 Adhesive can bond metals treated with hot dip G60 and G90 galvanizing, and ITW says that its adhesive is compatible with metals treated with most galvanizing processes commonly used today. Galvanized components can be bonded to non-galvanized metals as well as composite and plastic components using the adhesive.
