The corrugated case is manufactured by Klabin - Brazil's largest producer and recycler of paperboard. The octagonal shape of the box was not only chosen from an aesthetic point of view, but also because it gives a perfect palletising pattern.
The two-layer bag, provided by DuPont Liquid Packaging Systems/Liqui-Box, has a 3.8-mil (96.5 mu) outside layer of a bi-axially oriented nylon composition and an inner layer of 2.5-mil (63.5 mu) polyolefin. DuPont Liquid Packaging Systems delivers the ready-made bags, both in 3 and 5-gal (11.35 and 18.93 ltr) sizes equipped with a dispensing tap. The bags are filled on the Liqui-Box model 1000 CIT-W filling machine with a capacity of four 5-gal bags/min.
Klabin wanted a sustainable packaging that could guarantee the quality of the water from the time of filling up till the moment of consumption. The definition of sustainable meant that it should be economically viable, environmentally and socially correct.
The economic viability refers to the price per litre of the new packaging, with a market price that should be between those of Brazil’s two most popular containers, a 20-ltr bottle and a 1.5-ltr PET bottle.
The definition ecological meant a 100% recyclable, biodegradable corrugated cardboard box made from renewable raw material resources harvested from the re-planted forests. The result is certified by the Forest Stewardship Council, the international body that governs proper management of forests and their production chains. The plastic bag and the dispensing valve are also recyclable.
And finally, the condition: social justice. The packages are guaranteed fraud-resistant, while the companies involved in the manufacturing collaborate actively in a positive development of the communities in which they are located.
In addition to environmental benefits, the corrugated cardboard box prevents light from entering, as well as it insulates the water from heat, with which the sensation of "fresh water" is much longer experienced than with clear bottles.
The strong corrugated cardboard box, printed in three colours on a white kraft liner, is sealed with hot-melt. The tamper-evident valve allows the bag to be filled without any manual contact with the water.
