Packaging Innovations Weekly Wrap - DuPont Launches New Bioresins

DuPont has launched Biomax TPS thermoplastic starch and Biomax PTT (polytrimethylterephtalate) injection mouldable resin, which it says expands its renewably-sourced portfolio of offerings for the packaging market.

Biomax TPS consists of sheet stock that contains 85-90 percent renewably-sourced content for thermoformed trays and articles, and resins for injection-moulded parts and containers.

Biomax PTT contains up to 35 percent renewably-sourced content for packaging applications and is especially suitable for use in injection-moulded containers, cosmetic packaging and other parts where polyesters are used.

DuPont Performance Materials Group Vice President Diane Gulyas says the new products support the firm's commitment to helping customers improve the sustainability of their value chains.

"These new offerings demonstrate the power of marrying DuPont's core competency in materials and polymer science with our leadership in bio-based technologies and renewable feedstocks to deliver offerings that provide comparable or better performance than the petrochemical-based materials they replace," she says.

CROWN HOLDINGS UNVEILS SPECIAL INK

Crown Holdings has unveiled several novel finishes and special ink that can be used to differentiate metal closures used on food and beverage products.

Crown's new finishes include a matte, metallic sparkle and a special colour-changing lacquer that changes with the movement of the package.

The finishes can withstand pasteurised and some sterilised filling processes, Crown says.

The special finishes were developed through Crown's Research and Development Centre in Wantage, UK, where the company has a dedicated Innovation Team supported by a network of technology specialists.

The internal printing development was managed within Crown's Goleniow facility in Poland.

BOSCH COMPANIES EXTEND PILLOW-PACK RANGE

Tevopharm and Doboy, two Bosch Packaging Technology companies, are extending their range of horizontal pillow-pack machines for the confectionery and food sectors by introducing the Pack-401.

The new machine is suitable for packaging products in trays, such as baked goods, stacked biscuits, crackers, confectionery items and frozen products.

The design enables the Pack-401 to operate as a standalone machine or to be integrated with other packaging systems such as Delta Robots, secondary packaging machines, product handling, and various infeed modules, Bosch says.

It achieves medium to high operating speeds for output levels of 20 to 400 products per minute or a film speed of up to 80m per minute.

The design allows for flexible changeover to various packaging formats for product widths up to 450mm or film widths up to 650mm.

GERRESHEIMER GOES MULTICOLOUR

'Multicolor' can be used for brand logos, usage instructions, expiry dates, barcodes, as well as calibrations and scales for some products.

The company says advantages of direct printing over labelling are obvious, namely the printing ink itself firmly comes into contact with the primary packaging.
