It might sound easy, but there are multiple factors in choosing the best cap or lid. With such a wide range of closures available in the market today, it can be tricky to choose the right one for your product. Depending on the item that needs to be packed, lid closures need to keep the contents secure, safe from tampering and ensure ideal dispensation. Often, some lid closures are preferred over others by a specific industry.
There are a range of different lid types for our glass jars.
The terms refer to the various properties of the lid:
Our lids are strong, easy to put on, and are coated with material on the inside that is non-reaction, safe, and helps to maintain a complete seal.
For any product where security is of utmost importance, safety buttons are a must-have. They show if the lid has been damaged in transit and air (and therefore bacteria) has entered the jar. It also shows if anyone has opened the jar and used or modified the contents. It can only be used if the product is hot when put in the jar, or there is the ability to use heating to seal it shut such as sterilisation in order for the vacuum to form.
The idea of twist off caps is that they are easy to remove- no need for a bottle or can opener. Most people can remove the lid easily, or have developed strategies (like hot water application or using a knife under the lid to break the seal) to do so. Fluted edges help to remove the lid by providing more grip via indentations.
There are factors that mean you may need a specific type of cap. Things that contain oil or that are highly acidic like pickles or olives need caps designed for them. Also, as mentioned above, if the product will be hot when put in the jar or heated, or cold-close. Call us to chat about the specifics of your product and its requirements, and we can advise.
