What to look for when buying plastic bottles?

Plastic packaging is very convenient and practical for storing cosmetics and food. They are light, do not absorb grease or water, and are easy to wash and reuse later. Dispenser bottles are more hygienic than other packaging. The lotions and lotions contained inside have less contact with the air than those kept in traditional containers. As a result, the products retain their freshness, aroma and appropriate consistency for longer.

Plastic bottles today are recyclable. As a result, plastics have become environmentally friendly materials (provided that the waste is handled properly by the users).

Features of plastics

However, not all plastic bottles are safe and suitable for any purpose. Although it is completely invisible, some plastics may release harmful substances, especially if they come into contact with selected products. That is why we should always check what materials they are made of, what their purpose and method of disposal are. Not all of them have the same strength and durability, which is important when we want to use them multiple times. The thickness of the material used is also important here.

How to check the type of plastic?

All plastics on the market have special markings, most often on the bottom. The symbols that can be found there inform about the substance from which the packaging is made and the method of its disposal. We will find out from the packaging whether the material is recyclable. The most common markings on plastic packaging are:

  1. PET/PETE — polyethylene terephthalate, a substance commonly used in the production of various types of food and cosmetic packaging, most often bottles for beverages. Also used for the production of some building elements. Disposable PET packaging should not be exposed to direct sunlight or used for food storage as it may produce toxic substances;
  2. PE-HD/HDPE — high density polyethylene, durable, safe and biodegradable. Most often, it is used for food and cosmetic packaging, as well as for the production of sails, skis and pipes. It is quite durable, you can use it many times;
  3. PE-LD/LDPE – low-density polyethylene, most often used in the production of food packaging;
  4. PP – polypropylene, commonly used in the food and chemical industries. Durable, resistant to many chemicals. It is used for the production of not only packaging, but also toys, pipes, electric cables and household appliances.

Less common markings on packaging are PVC / PVC – polyvinyl chloride, which can be harmful to health (it must not be burned), PS – polystyrene, more commonly known as polystyrene, and OTHER – marking of less known substances such as nylon, acrylic glass, polycarbonates.

Sometimes you can see the BPA Free or BPA 0% marking on the packaging, which means that they do not contain toxic bisphenol (BPA).
