Used in the food, cosmetic and pharmaceutical industries, capping machines are an important part of the finish of any products that need a cap or closure. The first point of contact before the customer consumes the product. The way the cap performs will have an impact on the consumer experience and that is why choosing the right capping machine is crucial for a successful introduction of your product. That is why at Autopack we are a market leader in supplying packaging machines, and we’ve created this guide on how to choose the right capping machine for your business.


What is a Capping Machine Used For?


Bottle-capping machines are used in a variety of industries, from food and beverage to chemical, cosmetics and even agriculture. Created to seal and efficiently reduce the risk of leaks, a capping machine is an essential part of product manufacturing and should not be compromised. At Autopack, we have a wide range of machines to choose from, and selecting the right capping system for you is something we can help with.

How Does A Capping Machine Work?


The type of closure or cap you are after can affect the type of machinery you will need. From simple handheld equipment to fully automated machinery, the capping process is relatively straightforward no matter how complex the machine may look.

Most bottle-capping and glass jar-capping machines follow the same step-by-step process.

  1. Cap or closure is placed on top of a jar, container or bottle, either manually or automatically.
  2. The cap gets tightened by either a machine or an operator.
  3. The sealed container is then moved onto the next stage of packaging.


Types Of Capping Machines


Here at Autopack, we are a top packaging machine manufacturer in the UK and have a selection of capping machines that will be a huge benefit to your production line. If you are looking to add a bottle capping machine to your organisation, you will first need to decide on the type that will be of most benefit to your products packaging. We can help you with that decision, whether you need an automatic, semi-automatic or manual machine.


– Automatic Capping Machine


If you’re looking for an easy-to-operate capping machine for your production line, then the automatic is a perfect place to start. A reliable addition, an automatic capping machine can handle changes in products or product size more easily than other types of machines. Usually operated by a press button, automatic machines can simply be integrated into any production line with ease.



– Semi-Automatic Capping Machines


Incredibly similar to automatic machines, the semi-automatic bottle-capping machine conducts the same tasks but will require an operator to place the closures or caps on top of the containers or bottles before feeding them into the machine. This is due to a semi-automatic machine not having an automatic delivery system. Still easily integrated into a packing line, the semi-automatic will just require the ability of an operator, this is something to keep in mind before purchasing.


– Manual Capping Machines


Manual capping machines are usually cheaper than semi-automatic and automatic, this is simply due to manual machines requiring an operator for the majority of the controls and activities. The operator of the machine will have to place the cap onto the bottle or container, as well as manually fix it. This type of bottle-capping machine is usually preferred for smaller-scale production lines.


Types Of Caps and Closures


The kind of capping machine you need will depend on the bottle or container as well as the type of closure or cap you need for the container. There is a vast selection of caps and closures to choose from. Deciding on the cap or closure before purchasing a bottle-capping machine is crucial to successful production.


– Screw Caps


These caps use a thread to secure to the container and are usually found on plastic bottles.


– Cork Caps


Recognisable from your favourite bottle of wine, a cork cap is usually used for bottle closures.


– Tamper Proof Seals


Used to keep products and customers safe, the tamper-proof seal is usually seen on bottled drinks or milk and their closures tend to feature tamper-evident bands.


– Child-Resistant Caps


Primarily used in pharmaceuticals for medicines, child-resistant caps have a mechanism that makes them more difficult to open.


– Press On Caps


Found on branded bottled beverages, press-on caps are secured to the container either using undercuts or beads.

 – Dropper Caps


Dropper caps are mainly used in medicine or cosmetics such as skin serums.


– T-Cork Caps


T-cork caps are usually found on products used by beverage companies for sealing corked bottles.


Maintenance Of Capping Machines


Cleaning is a crucial part of maintaining your capping machine and keeping it in tip-top condition. Scheduling regular cleaning and maintenance is always a good idea, however, there are some simple tips you can do to keep your machine in working order such as wiping your machine down at the end of the day and cleaning up any spillages as they happen. Each machine will require different cleaning solutions, so be sure to check the manual on how to clean your bottle-capping machine.


Things To Consider When Buying A Capping Machine


There are plenty of things to consider before purchasing a capping machine for your production line. Remember to always keep in mind the industry you are creating your products for and the type of product that will be concealed in the container.
