Advantages and disadvantages of plastic bottle packaging

Advantages:

1. Most plastic bottles have strong anti-corrosion ability, do not react with acids and alkalis, can hold different acidic and alkaline substances, and ensure good performance;

2. Plastic bottles have low manufacturing costs and low use costs, which can reduce the normal production costs of enterprises;

3. Plastic bottles are durable, waterproof and lightweight;

4. They can be easily molded into different shapes;

5. Plastic bottles are a good insulator and have important insulating properties when generating electricity;

6. Plastics can be used to prepare fuel oil and fuel gas to reduce crude oil consumption;

7. Plastic bottles are easy to carry, not afraid of falling, easy to produce and easy to recycle;

Disadvantages:

1. The main raw material of beverage bottles is polypropylene plastic, which does not contain any plastic. It is used to hold soda and cola drinks. It is non-toxic and harmless and has no adverse effects on the human body. However, since plastic bottles still contain a small amount of ethylene monomer, if alcohol, vinegar and other fat-soluble organic substances are stored for a long time, chemical reactions will occur;

2. Since plastic bottles have gaps during transportation, their acid resistance, heat resistance and pressure resistance are not very good;

3. It is difficult to classify and recycle waste plastic bottles, which is not economical;

4. Plastic bottles are not resistant to high temperatures and are easy to deform;

5. Plastic bottles are petroleum refining products, and petroleum resources are limited;

We must make full use of the advantages and disadvantages of plastic bottles, continuously develop advantages and disadvantages, avoid the disadvantages of plastic bottles, reduce unnecessary troubles, and ensure more functions and values of plastic bottles.
