What are the advantages and disadvantages of PET plastic bottles

The advantages of PET plastic bottles include:

1. Lightweight and convenient for long-distance transportation of products, it can save transportation costs for beer companies.

2. It is more convenient to pack beer and other beverages, and has better light avoidance.

3. There is greater flexibility in bottle type and capacity selection, allowing for the production of products with different bottle sizes and capacities, thereby enriching the variety of product designs.

4. Recyclable and reusable.

The disadvantages of PET plastic bottles include:

1. The adaptability of beer filling equipment is poor, for example, it cannot be cleaned with a bottle washing machine and can only be rinsed with high-pressure sterile water. The sterile state inside the bottle cannot be guaranteed, especially for bottles that have been stored for a long time.

2. Not heat-resistant, unable to pass through the pasteurization machine, and requires a high level of sterility in the packaging workshop.

3. The labeling method is different from that of glass bottles, and the labeling machine needs to be modified.

4. After filling, carbon dioxide is lost by 10% -15%, and oxygen enters the beer to exacerbate its aging.

5. We need to improve our ability to protect against UV rays and prevent the occurrence of sun odor in beer.

6. Regardless of the type of organic synthetic material used, it is inevitable that a small amount of organic monomers will appear. When the inner wall of the bottle comes into contact with beer for a long time, a small amount of organic matter will inevitably dissolve.
