Does the Recycling of PET Plastic Bottles Need to "Twist the Cap and Tear the Label"?

Coke bottle is a common plastic bottle, and it is also a container that people come into contact with every day, such as various beverage bottles, soy sauce bottles and so on. The raw material for making plastic bottles is PET (Polyethylene terephthalate), so it is also called Coke PET bottle.

The initial use of PET was for man-made fibers, film, tape, etc. PET Coke bottles have the following characteristics:

1. Light weight and easy to carry (the weight is about 1/7 to 1/10 of the same size glass bottle)

2. Impact resistance, high strength (can show sufficient strength when dropped)

3. Use in compliance with food hygiene regulations

4. Good transparency and luster, as a container can show a beautiful appearance

5. The container can be recycled and reused, which is good for environmental protection (relatively speaking)

Because PET bottles have the characteristics of good toughness, light weight, airtightness, acid and alkali resistance, etc., they are often used as bottled beverage packaging for mineral water, soft drinks, juices, carbonated drinks, etc.

Since 1976, PET has been mass-produced and widely used in food and beverage containers. Modern society manufactures and uses PET bottles in large quantities, but PET bottles cannot be decomposed naturally, so they must be recycled and reused after they are used.

From the perspective of the production process, the body and cap of the PET plastic bottle are completely produced separately. The material of the bottle body and the bottle cap are different, mainly because of the elastic coefficient. Since PET has a small elastic coefficient and is easy to deform, it is very unsafe to seal as a liquid. Therefore, HDPE is usually chosen to make bottle caps and gaskets, which are convenient for transportation and sales. Because of this, in Japan, Taiwan of China and other regions, the bottle cap, bottle body, and label are separated before recycling PET bottles. But in Europe, there is no need to separate the bottle cap, bottle body and label.

Our point of view is that screwing bottle caps and tearing labels will reduce the processing work of recyclers, and I believe recycling industry chain companies are also welcome. But it should be more welcome for recycling companies: I hope consumers can pour out the remaining beverages and keep the bottles clean, dry, and odor-free.
