‘Paper 2.0 imparts the hand-crafted look of paper combined with various textural options, and all with the multi-faceted functionality of flexible film’, says Linda Carroll, Ampacet’s director of global colour insight. The new development offers ‘a sustainable, cost-effective alternative to paper’, where costs are currently at an all-time high, Brownfield comments. When used as an outer layer of a multi-layer film construction, it eliminates the need for secondary paper lamination processes necessary with traditional paper products and the storage demands of a bulky paper inventory, Ampacet adds. Paper 2.0 is said to be well suited for a wide variety of applications, including shopping bags, branded and novelty tape, shipping envelopes, meat and bakery wrapping, pet food bags and stand-up food pouches. It can also be used for applications such as banners, maps, menus, beverage labels, book jackets, instruction manuals and house wrap, according to Ampacet. Founded in 1937, Ampacet is a privately held company that employs more than 2000 people worldwide. It operates 24 manufacturing sites and four research and development centres in 17 countries, and sells its products in more than 90 countries. The company’s products include black, white and colour masterbatches as well as a wide range of polymer additives. Contact: Ampacet Corp, Tarrytown, NY, USA.

Riverdale Global launches antimicrobial agents for polyolefins & engineering thermoplastics

U

S sealed liquid additives and colorants producer Riverdale Global has launched a new series of antimicrobial agents for use with polyolefins and engineering thermoplastics. The company claims that its +Clean™ additives provide more-effective product protection at lower letdown ratios than masterbatches. According to the company, its new antimicrobial products can be used at let-down ratios of only 0.2–0.5% and disperse more readily in the polymer matrix than pelleted concentrates. As a result, they yield greater antimicrobial protection while saving on additive costs, it claims. The +Clean antimicrobials are inorganic silver-based formulations that prevent discoloration, odours and product degradation caused by the growth of bacteria, mould

and yeast, Riverdale reports. They have been optimized for colour retention in both indoor and outdoor environments, it says. The range currently comprises +Clean AM-139 liquid additive for use with polyethylene or polypropylene at let-down ratios of 0.2–0.4%; and +Clean AM-150 liquid additive for use with engineering thermoplastic resins at let-downs of 0.3–0.5%. ‘The liquid form of Riverdale Global’s +Clean antimicrobials ensures low and precise metering rates and improved mixing and dispersion’, says Charles B. Irish, the company’s VP of product development. Enhanced dispersion is particularly important for product protection because it promotes an even distribution of the agent at the surface, he explains. +Clean antimicrobials are intended for use in housewares, consumer electronics, healthcare devices and other products in applications susceptible to microbial attack. The new additives are available in pails or drums, in custom blends with liquid colours, or as one of the company’s recently launched GlobalPlus™ line of sealed, single-additive dispersions [ADPO, March 16].

Teijin introduces flame retardant masterbatch for textiles and resins

J

apanese high-performance fibres and composites producer Teijin Ltd reports that it has developed a flame retardant masterbatch for use with textile fibres as well as resins. The new product incorporates the company’s proprietary phosphorus-based FCX-210 flame retardant launched in 2013 [ADPO, November 2013] in combination with a polymer carrier suitable for use in fibre applications. According to Teijin, FCX-210 lends high flame retardancy to a broad range of plastics without losing any of its flame resistance or changing the original characteristics of the plastic. Additionally, it is effective at relatively low addition levels, the company says. Production of the halogen-free product began in Taiwan in 2014, and FCX-210 has since been widely adopted for electronics and automobile parts, Teijin reports. The new masterbatch FCX-210 will bring those same strengths to textile manufacturing, as well as offering the world’s highest transparency for unmatched colourability, the company claims. Moreover, unlike traditional phosphorus-based flame retardants, FCX-210 is insoluble in the polymer, providing an
