Generally, most old plastic bottles and waste plastics have great utilization value, such as packaging materials, daily necessities, industrial supplies, household items and so on.

It can also be recycled to make clothes, because the main materials of plastic bottles are generally PP (polypropylene) and PET (polyethylene terephthalate), and PET is one of the most important raw materials for making clothes fabrics.

Bottles made of PET can be made into packaging sheets, blister boxes, packaging straps, chemical fiber spinning, cotton, nylon fabrics, geotechnical filters, etc.

Extended data:

There are three kinds of plastic products for food packaging, namely PVC, polyethylene and polystyrene.

In fact, using plastic products to contain edible oil in a short time is not harmful to human health. If they are used to hold edible oil for a long time, they will greatly pollute food, thus causing harm to human health.

So we can know that plastic bottles are easy to carry, not afraid of falling, and also have the characteristics of acid and alkali resistance, convenient production and favorable recycling. But in order to protect the environment, we should use less plastic products.
