Sustainable Packaging | Why is PET the Most Widely Recycled Packaging Material in the World?

Why choose PET packaging?

PET is the most commonly used plastic in beverage and hard food packaging. Around 27 million tons of PET are used globally, with the majority (about 23 million tons) used to manufacture bottles. For packaging developers and sustainable cosmetic packaging manufacturers, PET's characteristics make it perform excellently in product packaging design and performance, meeting the needs of various complex products in different packaging sizes.

Firstly, PET is known for its transparency. PET has a light transmittance of up to 90%, with good transparency, low mist, and high glossiness. Therefore, transparent, lightweight, and less fragile PET packaging has become the perfect substitute for glass and other plastic resins.

Secondly, PET is chemically stable and has good resistance to organic and inorganic chemical solvents such as oil, acid, alkali, and salt, and will not react with the products themselves.

At the same time, PET has high mechanical strength, strong compression and seismic resistance, is not easily dropped and broken, and its light weight helps to significantly reduce transportation costs, giving it greater advantages in transportation and logistics.

For consumers, a good package must first perform its basic function: to protect and preserve the color, style, and other features of the contained product intact. Secondly, as people's environmental awareness continues to increase, whether packaging materials can be recycled and reused has also become one of the important criteria for consumers' choices. They also hope to support environmental protection through their daily recycling behavior. PET's many characteristics also make consumers at ease.

The impact on the environment

In addition to fulfilling its basic function, sustainable packaging also needs to consider the impact of its entire life cycle on the environment, that is, the impact of the entire process of obtaining raw materials, production, use, and disposal of products (or services) on the environment.

PET packaging is becoming lighter and more durable, so it can effectively transport products without the need for secondary packaging, thereby greatly reducing fuel demand and greenhouse gas emissions during product transportation.

The specific impact of original PET and recycled PET can also be measured by life cycle assessment, comparative indicators, and social impact studies. Nowadays, the production efficiency of PET resin and packaging is increasing, and the energy and resources used are less than ever before. Most packaging manufacturers have begun to realize that PETG cosmetic bottles can be recycled and processed into clean raw materials after safely preserving their contained products.

For all consumers, when you purchase products packaged with PET, it also means you have chosen a recyclable packaging.

After being placed in the recycling bin, the PET container will be collected, sorted, processed, cleaned, and then re-manufactured into various new products, including fibers for clothing and carpets, soft furniture and sleeping bags made from fiber filling, tying trays, food and non-food packaging bottles, and thermoformed packaging such as cups and takeout containers.

Recycling PET packaging can keep it away from landfills, but its role is far from that. Recycled PET resin is also a valuable manufacturing material that can be repeatedly processed and reused in packaging products.
