BOTTLE MAKING 22 PETplanet Insider Vol. 23 No. 09/22 www.petpla.net PET milk packaging in India India has been increasing its availability of milk and dairy products for over 20 years and is now the world’s largest producer and consumer of dairy products. Its rural economy is heavily dependent on the dairy sector as a source of jobs and revenue. While it has the world’s highest population of cattle, milk production per animal is much lower than other major dairy producers. Almost all dairy products are consumed domestically in India, with the majority sold as fluid milk. There is thus a lot of room for growth and added value in the Indian dairy business. Dairy products in India are available as liquid milk, UHT milk, flavoured milk, curd, flavoured & frozen yogurts, lassi, buttermilk, probiotic dairy products, buttermilk, table butter, ghee, cheese, khoya, cream, skimmed milk powder, dairy whiteners, sweet, condensed milk, ice cream, whey, organic milk, milkshake, and dairy sweets. Liquid milk has the highest market share of other milk-based products or dairy products. A recent study says that the dairy market in India reached a value of INR 13,174 billion (€160.46 bn) in 2021 and it is expected to touch INR 30,840 billion (€375.63 bn) by 2027; a CAGR of 14.98% from 2022-27. Milk is considered to be the complete food as the composition of milk consists of 87.7% water, 4.9% carbohydrate, 3.4% fat 3.3% protein, and 0.7% minerals. The composition of milk may vary slightly, depending upon the animals - cow, buffalo, goat - and the type of breed but milk is very much susceptible to the attack of micro-organisms and can become spoiled within an hour when exposed to some ambient conditions. Because of this, all kinds of fresh liquid milk can be subjected to heat treatment to eliminate micro-organisms and extend shelf life. Treatments include pasteurisation, sterilisation and ultra-high temperature sterilisation (UHT). Liquid milk is generally sold in glass bottles, high-density polyethylene (HDPE) and PET bottles, paper-based multilayered composite liquid cartons, and plastic pouches. Global trends in the packaging of milk products According to a market study by Euro Monitor, the use of PET as a packaging material is expected to continuously grow within the liquid dairy sector globally. Liquid milk products packaged in PET were forecast to reach 16.2 billion units worldwide by 2022. Bottle sizes up to 500ml represent more than two-thirds of those PET packages and were projected to reach 10.35 billion units in 2022. The growth of PET bottles for milk packaging can be credited its 100 per cent recyclability, excellent barrier properties, and secure closures systems, which ensure food safety. Moreover, from transparent to opaque solutions, PET packaging can deliver extended shelf life without the need for aluminium foil, enabling a more sustainable business.
