What are bottle caps for

Lids for pet bottles – this is a simple and functional component that allows you to reliably isolate the contents of the container from external factors. What are lids for? Alcoholic and non-alcoholic drinks, juices and water, cosmetics and detergents, pharmaceutical products – such products are found at every step.

What are the advantages of plastic lids:

  • resistance to mechanical and chemical influences, humidity, temperature fluctuations;

  • ease of manufacture;

  • tightness – allows you to save the quality and volume of the product;

  • concise design.

Despite the external simplicity, the production of caps for pet bottles – this is a responsible process that requires compliance with a number of norms and standards.

What requirements must plastic lids meet?

Norms for PET bottle caps:

  1. Environmental friendliness. All products must be safe for humans, do not contain toxic compounds and do not release harmful substances into the environment.

  2. Neutrality. The material from which the cap of the pet bottle is made should not react with the contents of the container.

  3. Tightness (even in conditions of temperature differences). The product should fit snugly to the neck and not let air through. In the case of caps for carbonated drinks, the possibility of escaping carbon dioxide should be excluded.

  4. Ergonomics. The shape and size of the lid should not create inconvenience in the process of using a plastic container.

  5. Hygiene. The surface of the lid should not attract dirt and dust, becoming a breeding ground for bacteria.
