The features of P•ink’s customized crown caps

With P•ink it is possible to independently customize 26 and 29 mm caps thanks to the online shop. Let’s take a closer look at all their technical features.

How are P•ink’s crown caps made?

The crown caps on the P•ink website are the same ones Pelliconi has made for the largest international producers of beer, wine, and beverages for years.

They are metal shells made of chromium-coated steel with thickness 220 microns and a double-lip liner.

You can do the customization yourself in the P•ink online shop, or make a request for more graphics on the same base color or to apply your Pantone to the top of the cap.

What are the features of the caps’ compounds?

All of P•ink’s customized caps with are equipped with a compound (otherwise called liner or sealing) that is applied by compression molding. This compound has been chosen specifically for the P•ink service and is made of soft plastic, ensures maximum performance in sealing the internal pressure of the drink, and can be, optionally, PVC free or Oxygen Scavenger.

What does a cap with a PVC-free compound mean?

A PVC-free crown cap seal guarantees food safety because the bottled beverage will not be contaminated by the chemicals in PVC. Also, it does not contain phthalates, additives, or harmful substances.

The compounds Pelliconi applies to P•ink caps are made of polyethylene and also act as a physical barrier against oxygen and other volatile substances.

This is also the best solution when considering environmental sustainability. Disposing them is not harmful because they do not release toxic substances such as dioxins into the atmosphere, and their production has a low environmental impact.

What is the Oxygen Scavenger and how does it work?

A cap with an Oxygen Scavenger seal is a PVC-free cap that also has a layer of sodium sulphite, which is an active compound that absorbs excess oxygen during the drink’s shelf life to preserve its features for longer. Beer is a good example; in contact with oxygen, it tends to become acidic.

The absorbent power is activated with humidity and heat and tends to disappear in the following 6 months, after which the cap becomes as a PVC-free barrier.

It is the ideal solution for those who want to delay beer’s oxidation process, in addition to organoleptic alterations. Generally, the most sensitive beers affected by this process are the light industrial ones with little flavor.

Cap compatibility with bottles and crowning systems

When choosing the caps for your beer, wine, or beverage we care about their compatibility with bottles and capping systems. So take a look at the bottles that P•ink’s crown caps go well with.

Are P•ink’s caps compatible with my bottles?

P•ink’s crown caps are compatible with all standard glass bottle formats:

  • Beer (both 33 cl bottles with 26 mm crown caps and 50 or 75 cl bottles with 29 mm caps)
  • Sparkling wines
  • Spumante
  • Cider
  • etc.

How important is the quality of the bottle for the cap to have a good seal?

The quality of the bottle’s glass as well as the quality of the workmanship affect the cap’s performance. The presence of imperfections on the surface, due to the poor quality of the glass, can affect the cap’s seal and therefore the taste of the bottled drink.

Will the compound have a good seal on glass?

The compound present on P•ink’s caps is in soft PVC-free or Oxygen Scavenger plastic. In our long experience, we have been able to ascertain that a light liner offers better performance reguarding the glass sealing.

What are the main bottling and closing methods?

The capping methods that can be used to close the bottles depend on the level of automation of the crimping tool used by the producer of beer, wine or any other beverage. So we can have:

  • Manual capping unit – Crimping is achieved by operating the unit with its lever.
  • Pneumatic capping unit – Alternate motion to achieve crimping, is performed by pushing the button/s that release compressed air and provide pressure.
  • Multi-heads capping machine – Caps are distributed to the heads through a proper feeding system (hopper-twister-chute). Bottles are driven through their own wheeling system; from filler, they come into axis with the matching head. The continuous process is entirely electro-mechanical, the alternate motion driven by a bearing-cam system aptly designed.

Depending on the level of industrialization and the number of heads, it is always advisable to carry out a series of tests and check all the cap/bottle/head combinations. This will help you calibrate the capping machine with the new P•ink caps.

Can I test out P•ink’s crown caps before making a purchase?

You can request sample caps and be inspired by the customization possibilities. However, you can also test the quality of the caps and the compatibility with your bottles and your capping machine.

Questions about the conservation and quality of P•ink’s caps

It’s important to learn how to best store them to maintain the product’s quality and the graphics.

How do you properly store the caps?

Crown caps do not have a limited shelf life, but they should be stored in a suitable environment, which is:

  • Dry
  • Ventilated
  • Protected from the light
  • Away from humidity and odorous substances

If the cap gets rusty, what could be the cause?

As mentioned above, the caps’ storage environment affects the maintenance of the product’s original qualities. A rusty cap certainly indicates a humid and poorly ventilated storage environment, which can also cause the compous to absorb bad smells.

Another factor that can lead to the formation of rust on caps is failing to dry them after bottling and pasteurization. In fact, if any metal cap remains wet, it will undergo oxidation in the cutting angle. That is why, if your capping system is not equipped with an automatic drying system, we recommend drying the bottles carefully.
