Functional Closures
Keizer International is a supplier of functional plastic closures for bottles and jars within the food, cosmetics and industrial markets. Dispensing closures enable products to be poured, dispensed or sprinkled in a controlled manner. This makes them ideal for packaging sauces, oils, herbs, powders and cosmetic products, amongst others.
Our range includes various types of dispensing closures, such as flip-top caps, top-up closures, flapper caps and pourers. Thanks to our experience with packaging solutions, we can advise on the right combination of closure, packaging and product characteristics.
Dosing closures are available in various standard sizes:
Diameter: Ø 18 mm to Ø 120 mm
Within these diameters, various heights and thread types are available, depending on the bottle neck and the intended application.
Our packaging specialists will be happy to advise you on the correct size and compatibility with your bottle or jar.
Dispenser caps are primarily manufactured from plastic materials suitable for food and cosmetic applications:
PP (Polypropylene)
A dimensionally stable plastic with good chemical and temperature resistance. Widely used for dispensing and pouring solutions.
PE (Polyethylene)
A flexible plastic that is highly resistant to various liquids and is widely used for closures and dispensing caps.
The choice of material depends on the product, the viscosity and the desired ease of use.
Dose caps can be customised to match the look and feel of your product and packaging.
Options include:
- Production in a range of colours
- A combination of multiple colours in a single cap
- Printing or branding
Our specialists will advise you on design, functionality and technical feasibility.
