The bottle pack is a hallmark example of sustainable packaging. First introduced in the china marketplace about four years ago, the packaging was more durable and more sustainable. Compared to blister packages, it uses about 20 percent less packaging materials in weight per piece, which creates an overall reduction of over 2,500 tons of packaging materials per year. Moreover, the bottle is recyclable, and last year, the bottle was reengineered to become even lighter. An innovative approach incorporating talc as a "filler" decreased the amount of plastic used by 50 percent and the overall bottle weight by over 25 percent, while still maintaining the integrity of the package. In europe and asia, popular gum products are also available in refill bags, further reducing packaging by allowing consumers to refill and reuse their original bottle packaging.
