Different Types Of Bottle Caps And Their Uses
When you open a new bottle of soda, beer or any other type of beverage, the top lid pops off and the bottle is ready for use. Some bottles will require PP resins for beverage caps. These are a popular choice as they are strong and durable. Other types include shrink sleeves and SRPs. While these may seem similar, they have different uses and can be colour coded to reflect the type of drink inside. For example, a liquor bottle may have a blue cap while a beer bottle will have a red one. This makes it easier for consumers to identify what type of beverage it is.
Bottle Caps Are An Important Part Of The Packaging Process
The primary function of a bottle cap is to securely seal the bottle and prevent the contents from leaking. Bottles are subjected to a variety of different forces during transportation, storage or use, all of which can pose a threat to the content and to the integrity of the packaging. A well designed bottle cap will adequately protect the contents of the bottle from these threats and ensure that it remains in good condition until it is eventually sold to the consumer.
Bottle Caps Also Serve An Important Marketing Function
Soda companies particularly use caps for promotion. A message is printed on the inside of the cap and people with the right message may win a prize. Since the bottle must be purchased to determine the message and win, people usually purchase more of the drink to increase their chances of winning. Another common type of promotional bottle cap is the commemorative version which celebrates a special occasion or event.
Bottle Caps Can Be Recycled
The bottle cap linerless mechanism is simpler and cheaper to manufacture than the traditional linered caps used in most beverage products. It also helps to reduce the amount of plastic that ends up in landfills because it eliminates the need for the plastic liner that comes inside the caps of regular water bottles.
Types Of Bottle Caps
- Glass Bottle Caps – Closures made of metal or plastic that fit over the top of glass bottles to seal them and protect the content from the elements and contamination. They come in a wide range of different styles to suit different applications and can be used to hold a wide variety of liquids including soft drinks, mineral water and alcoholic beverages.
- Screw Cap – closures that are screwed on over the top of the bottles to protect the contents and allow for easy opening once the bottle has been removed from the package. They are commonly used on oil, vinegar and other liquid-based products such as sauces and salad dressings.
- Snap On Cap – lids that are made to fit over the mouth of the bottle so that they can be snapped into place without the need for any special tools or equipment. They are often used on small bottles of alcohol such as spirits and liqueurs and are ideal for storing small quantities of the liquid for use at a moment’s notice.
- Child Resistant Closures – also known as CR numbers, these closures have special seals around the edges that make them difficult to open without the proper tools and they are designed for use by children to help prevent accidental spillages of the liquid contained within the bottle.
