Embrace copolyester: shrink film to offer ultimate design freedom

Eastman Chemical Company : 03 May, 2002  (New Product)
Eastman Chemical has introduced a new material designed specifically to meet the needs of the shrink film market: Embrace copolyester is a resin that provides maximum design freedom and maximum shelf appeal for the packaging designer due to its ability to produce attractive graphics and a label that can fit to high contour containers.
The growing recognition of the importance of packaging as an advertising and marketing vehicle puts increasing demands on the shrink film industry. To meet the need for shrink film that can perform, Eastman Chemical developed Embrace copolyester specifically for shrink film applications. It is a highly specialized copolyester with a combination of properties that makes it ideal for full-bodied shrink film labels as well as wine caps, tamper-evident seals, overwraps, and multipackages.

As the desired material for full-bodied labels, Embrace copolyester provides the properties necessary for today's demanding packaging. Its low haze, high clarity, gloss, and sparkle result in sharp, jump-off-the-shelf graphics and printing. Its ability to be decorated and embossed provides exciting new options for shrink labeling.

At the same time, its shrink capabilities allow package designers to promote brand identity and enhance shelf appeal through highly contoured containers.

While using Embrace copolyester provides exceptional benefits for brand owners, its processing ease assists converters and packer/processors throughout the development chain with economical productivity enhancements.

Embrace provides a winning mix of advantages for brand owners, packer/processors, converters and printers. Key advantages include:

Advantages to brand owners
High ultimate shrinkage
Embrace copolyester's high ultimate shrinkage provides the freedom to create innovative, eye-catching package designs. With the highest shrink rate of any commercially available films, full-bodied shrink labels made from Embrace copolyester can supply a tight fit for highly contoured, slim-necked, and unusual-shaped containers. The potential for greater than 70% shrink through custom configuration will maximize the impact of labels on glass, plastic, or cans.
High gloss, excellent color, clarity, good printability
This combination of aesthetic properties means brand owners can draw consumers' attention to the store shelf. With novel 360 degree printing and full-bodied label designs that incorporate multicolor or high-quality print, designers can highlight their products' best properties while utilizing the labels full display capability.
Recyclable
Embrace copolyester is recyclable and environmentally responsible.

Advantages to Packer/Processors
Flatter Shrink Curve and Lower Onset Temperature
With a flatter shrink curve and lower onset temperature than competitive resins, Embrace copolyester is capable of running under demanding quality conditions and at high production speeds in existing shrink tunnels.
Low Natural Shrinkage
Film stock of Embrace copolyester can be stored under normal room temperature conditions without concern for unwinding difficulties or label deformation because of its low natural shrinkage.
High Shrink Force
Once shrunk onto a container, Embrace copolyester's high shrink force prevents label loosening, which results in less than optimum package appearance.


Advantages to Converters and Printers
Ease of Printing
With a high surface tension of greater than 45 dyne/centimeter, Embrace copolyester can be easily printed on either rotogravure or flexographic printing equipment with no need for corona treatment.
Ease of Solvent Seaming
Embrace copolyester is amorphous and can be easily solvent seamed. In tube-forming operations, it can be seamed on standard heat-sealing and solvent-seaming equipment common to the shrink label industry.
Higher Printing and Seaming Productivity
The toughness of Embrace copolyester means fewer line breaks and higher printing and seaming productivity.
