What Is The Role of Metal Screw Caps

The debate over bottle caps in the wine world has been going on for a long time: is it better to use corks or metal screw caps for wine? Repeated experiments by the Australian Wine Research Institute in the first decade of the 21st century proved the superiority of screw caps over other bottle caps, preventing wine from spoiling and random oxidation.

Many friends mistakenly believe that screw caps will inhibit the aging of red wine, but in fact, research shows that the aging process is completed in an anaerobic state. The oxygen dissolved in the wine when the bottle is sealed and the part of the oxygen between the wine bottle and the wine will be consumed within one month after the bottle is sealed. After that, the changes in the wine are all carried out in an anaerobic state.

Screw caps are usually composed of two parts: a metal cap and a plastic liner, and are recyclable. Compared with natural corks, screw caps have lower costs, better sealing, and are more conducive to retaining the fruity aroma of wine. They also reduce the probability of cork contamination and are suitable for preserving wines with a fruity aroma. In addition, wines sealed with screw caps can be easily opened without any corkscrew.

Aluminum is a white light metal with abundant resources. Its output is second only to steel, and its application in the packaging industry ranks first among non-ferrous metals. Aluminum is generally used as a packaging material, including aluminum plates, aluminum blocks, aluminum foils and aluminum-plated films.

Aluminum has a very low water vapor permeability and is completely opaque, which can effectively avoid the harmful effects of ultraviolet rays. Its gas barrier, moisture resistance, light blocking and fragrance retention properties far exceed those of other types of packaging materials such as plastic and paper. Therefore, aluminum packaging can maintain the quality of goods for a long time and has a long shelf life, which is especially important for food packaging.

Aluminum foil for bottle cap has excellent processing performance, mature processing technology, and can be produced continuously and automatically. Aluminum packaging materials have good ductility and strength, and can be rolled into plates and foils of various thicknesses. 8011 aluminium sheet is one of the popular choices.

8011 aluminum foil features

1. Good strength, easy processing, chemical resistance

2. Good corrosion resistance, weather resistance, and low temperature resistance

3. Good reflectivity, no magnetism, sound absorption, good thermal and electrical conductivity

Application

It is often used as aluminum foil sheets with the main function of making bottle caps. It is also used in radiators. Most of the applications are aluminum foils, such as pharmaceutical packaging, food packaging, cable foils, milk cap materials, food container foil, sealing foils, tape foils,etc.

As one of the aluminum bottle cap material suppliers, Haomei Aluminum has rich types and alloys of aluminium bottle cap materials for making various bottle closure. Welcome to leave message below to inquire what you need.
