" There is a huge demand for safe drinking water in developing countries such as India, and in many countries in the Middle East and these countries and regions have become the target market for many multinational bottled water manufacturers," the analyst Sharanraj from Technavio (London) Packaging research company said. The company recently released a new report-the Global Plastic Packaging Market 2017-2020, and he indicated that "during the forecast period, bottled water per capita consumption will increase, which will promote the market demand for plastic packaging."
As a trend, lightweight involves the redesign of packaging materials which tends to realize weigh reduction without sacrificing quality at the same time, The research and development team of plastic packaging suppliers has been working to develop lightweight and easy to carry packaging. Furthermore, the reduction of the weight of packaging material and new structural improvements in the form of packaging can also help suppliers reduce transportation costs.
At current market, a 0.5 liter PET bottle weighs 12 grams at average while Westinghouse's pet bottle weighs only 7.95 grams, 34% weight less compared with the traditional PET bottle while its maximum load performance increased by 32%. In this way, the cost saved on raw materials can reach up to $13 million annually.
"Lightweight PET bottles require less raw materials in production, in turn, the recovery rate of such bottles has increased by 75%, and energy consumption in production has dropped by 23%," Sharan said, "and greenhouse gas emissions have fallen by 26% and waste landfills have fallen by more than 20%."
Manufacturers use different methods to design PET water bottles to improve their barrier properties. Innovative technologies are constantly being developed and applied to improve impermeability and eliminate the risk of harmful substances entering these containers. One of these is a plasma coating on PET film, which is only 50 nanometers thick, but the bottle is still easy to recycle.
