Aluminium closures for bottles

Aluminum closures are an integral part of a bottle’s and brand’s design and presentation. Herti makes available more than 40 closure size types, covering 90% of all aluminum closures on the market.

Closures with the HL sign are delivered with consistent quality to over 50 countries around the world. Quality and safety are the company’s top priorities through strict control of the whole procedure and the use of certified raw materials.

Herti has been ISO 9001 certified since 2000 and has had BRC/IOP accreditation for the Global Standard for Packaging and Packaging Materials since 2010. In 2023, Herti became ISO 14001 and ISO 45001-certified.

Aluminium closures are very often used on spirit bottles. However, closures with dimensions 31.5mm × 24mm and 31.5mm × 44mm with olive oil pourer liners can also be utilised for sealing olive oils, while closures with dimensions of 28mm × 15.4mm plus PVC compound are used for carbonated drinks bottles.

Screw caps for wine bottles

Herti brings forward innovative products that meet the needs of wine producers as well as the worldwide requirement for wine bottles with aluminum screw caps. ‘Vinstar’ is the trademark for aluminium wine closures produced by Herti.

All types of aluminium closures that Herti produces have SARANEX or TIN liners. The most sought-for dimensions for wine are 30×60, 28×44, 30×24,25×43,25×17,22×30, and 22×15.

Aluminium and plastic closures for soft drinks

Herti offers aluminium and plastic closures for water and soft drinks bottles in dimensions such as 28mm x 15.5mm, 30mm x 25mm, PCO; BPF, 48mm x 41mm. The company also produces plastic handles.

The composite closure is the most popular solution for mineral waters and is called DORADO. This is an aluminium closure with a plastic safety ring that is tamper-evident and protects from injuries. This cap is designed for high and middle-class bottles of still and sparkling water. This solution is suitable for ozone and sensitive waters as the compound it uses is PVC-free.

Eco-friendly packaging production

Herti also supports energy efficiency by investing in state-of-the-art technologies.

Herti is an environmentally conscious company with a clear aim to use natural resources. In the last years, the company has made significant progress in using green technologies to boost its production process. Herti recently invested in new pioneering technology, the Mailänder 280 by Koenig & Bauer, in order to enhance the print quality of decorative features while reducing its environmental impact. The new line uses UV-LED drying, which is energy-efficient and consumes no natural gas and less electricity, at the same time as it eliminates CO(2), ozone, and heat emissions.

A recent lifecycle assessment study revealed that recycled aluminum uses 95% less energy in comparison with producing primary material. One-third of the aluminum Herti uses in its production is recycled.

Herti is a SEDEX and EcoVadis member and is highly committed to the environment as it continuously reviews its material sources to ensure they are eco-friendly and ethical.

As an Ecopack partner and shareholder, Herti meets all sustainability principles.
