There are many standards for manufacturing plastic water bottles, as I will discuss below. The plastic bottle produced must be from a suitable plastic material and must also have adequate length and strength in terms of capacity. Another important standard for producing plastic water bottles is to have an organic solid also called "semi-synthetic" as they have a unique characteristic of being malleable. The aim is to allow plastic water bottles to be molded into any desired shape. This also makes it suitable for the production of the desired plastic bottles depending on the brand. Additionally, some companies use “PET” which is short for “polyethylene terephthalate.” This PET is used to make plastic water and beverage bottles. PET is composed of carbon, hydrogen and oxygen and therefore, when it burns, it produces carbon dioxide and water and leaves no toxic residues. Thick plastic bottles can be a disadvantage as they sometimes tend to melt when exposed to sunlight. This is known to not be helpful to the quality of water used by people. It most likely has other health effects. Because it leaves no toxic residue, the use of PET has become one of the standards for the production of plastic water bottles. Standards for manufacturing plastic bottles vary from country to country, such as the United Kingdom (UK) standards. it is different from that of the United Arab Emirates. In the UK the percentage of plastic allowed varies from 30 to 50%. In the United Kingdom, however, the percentage of plastic allowed is between 40 and 70%. The reason this is the standard in the UK is because in the UK they are rarely exposed to the sun so a high percentage is not required. plastic to...... half paper ......during the company after being produced. Another point that is important to mention. Water placed on supermarket shelves cannot legally remain placed on the shelf. On the other hand, sale is not allowed even after a period of six months. These conditions vary from country to country based on laws. One of the most important points is that all water bottles should be incubated together for no more than six months. The law states that from the date of production the water bottles cannot be sold for more than 6 months from the date of production. This is even if the water produced expires within one year from the date of production. Last but not least, the most important condition for water bottles, a win-win, is that they must be placed in refrigerated shelves or refrigerators
