The Leading Role of PET Packaging

2018-08-21 17:21 Tuesday


PET was first used as the base material of film. In the mid-1980's, the Coca Cola company became the first to apply PET in carbonated drinks. In 2001, Xiaoyangren Biological Dairy Group pioneered PET dairy beverage packaging in China.

Polyethylene terephthalate, commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fibre for engineering resins.

The annual growth rate of PET-packed UHT dairy products is more than 100%.

PET is considered to be the most environmental-friendly packaging material in the United States, with PET bottles also becoming prominent in Europe. A report from PCI Executive Search Consultants reveals that PET has great promise in the dairy packaging industry.

PET packaging has also significantly impacted the Chinese market. PET packaged brand “Nutrition Express” from Wahaha achieved sales figures of half a million in the first month, and 5 million within the first four months.

Most PET-packaged dairy beverages, including “Nutrition Express”, “Prince Milk”, and “Fruit Flavored Dairy Beverage”, have achieved robust sales.

Half of the liquid milk products in the global market are paper-packaged, and one third have plastic packaging. However, two-thirds of China’s liquid milk products are paper-packed, a significantly higher proportion than the global average.

Generally speaking, the packaging for pasteurized milk is composed of roof-paper and monolayer plastic packaging bags; UHT milk is always packed with paper and synthetics of polythene and aluminum foil.

Paper packaging has facilitated the rapid development of China’s dairy industry, but packaging costs have been difficult to contain. High packaging costs threaten to offset many of the gains that have been made, making packaging upgrades a matter of the highest priority for dairy enterprises.

Unique packaging is essential for attracting consumers, but most of the liquid milk on the market is packed with Tetra pack or Combibloc, which are similar and lack distinguishing characteristics.

Therefore, in order to achieve optimal sales, dairy enterprises should strive to decrease packaging costs, improve product quality, and as a means of achieving both goals, introduce distinctive packaging.

Thanks to the non-toxic, odorless and reusable properties of PET, it is arguably the best option for packaging. PET serves as an effective barrier, and is transparent durable, and corrosive resistant, preventing the penetration of oxygen, carbon dioxide and other gases. In doing so, PET packaging can help to extend dairy products’ shelf life and enhance flavor. Furthermore, PET packaging is easy to manufacture, lightweight, moldable and portable.

Perhaps most importantly, PET is as clear as glass. The latest market research confirms that products with clear packaging are more marketable and 10% more expensive on average than non-clear products.

PET packaging retains a smooth surface and texture without compromising its ability to protect the product, making it especially suitable for creative packaging. Furthermore, PET has been demonstrated to maintain the original flavor and taste of dairy products.

PET packaging is ascendant in the liquid milk industry, with an annual growth rate of 5.8% from 2011 -2018. The projected number of PET packages is projected to exceed 1.49 billion in 2020, a 9% increase from 2018, with higher growth yet in the mature European market.
