What are Types of Bottle Cap Sodas

The "hiss" sound when you unscrew the soda water is the prelude to the burst of bubbles and happiness. Behind this crisp sound, there is not only the magic of carbon dioxide, but also the exquisite design and special material of the bottle cap soda.

Raw Material

Plastic bottle cap

Plastic is one of the most commonly used materials for soda bottle caps, among which polyethylene (PE) and polypropylene (PP) are the most common. PE material is soft while PP material is harder. Some bottle caps that need to withstand greater pressure, such as bottle caps with special sealing designs, often use PP materials.

Metal bottle caps

Metal bottle caps also account for a certain proportion in soda water packaging, and the most common ones are aluminum and tinplate. Aluminum bottle caps have the advantages of light weight, corrosion resistance, and good sealing. Its surface can be treated in various ways, such as anodizing, to make it more beautiful and wear-resistant. Aluminum easy-pull caps are widely used in soda water can packaging.

Wood and other materials

In addition to plastic and metal, some soda water bottle caps are made of wood. For example, the Elephant brand soda water bottle cap is made of high-quality natural wood. It complements some soda water brands that emphasize the concept of naturalness and purity.

Types of Soda bottle caps

Screw bottle caps

Screw top bottles are undoubtedly the most common ones. They fit tightly with the bottle mouth through the thread, and can be opened and closed by rotating the cap. They also have good sealing performance and easy opening experience. Moreover, the production cost of screw caps is relatively low, which is suitable for mass production. In terms of materials, screw caps are made of both plastic and metal.

Easy-pull caps

Easy-pull caps are commonly found in cans of soda water. This cap is cleverly designed. Consumers only need to pull the pull ring to open the cap instantly without the help of any tools, which greatly improves the convenience of drinking. Easy-pull caps are usually made of aluminum, the same material as the main body of the can. While ensuring the sealing, it can also achieve overall lightweight.

Press-type bottle caps

Press-type bottle caps are used in some high-end or functional soda water packaging. This type of bottle cap is opened by pressing, and usually has a special valve structure inside. When pressed, the valve opens and the soda water flows out. When released, the valve automatically closes, effectively preventing liquid dripping.
