Details

The manufacturer has developed a water based technology for internal protection of metal can bodies and ends for the food, beer and beverage, aerosol and general line market segments. Internal water based coatings are recognized by fillers of beer and beverage cans as providing the highest levels of protection. However, with the industry moving to more light-weight and therefore more flexible canning solutions, this poses a challenge as it puts new demands on the coatings used inside the cans. These coatings perform a dual role:
 
•Protecting the beverage from the metal
•Protecting the metal from the beverage.

Which is why the manufacturer developed an ultra-flexible lacquer which flexes with the new light-weight steel cans, yet still retains a perfect barrier to protect the drinks.This high level of protection is becoming increasingly important, especially as more aggressive and flavor sensitive products – such as iced teas and isotonic drinks – are being introduced to the market.
The new coating was developed by AkzoNobel Packaging Coatings under the brand Aqualure® .  These products are now being used as internals by manufacturers of steel DWI food cans in Europe, US, Asia and Africa.
The content in this entry has been obtained from publicly available information sources only (e.g. press releases, website and trade press articles) and is subject to completion of a validation process with the technology supplier.

Potential Benefits

This technology supports the ongoing efforts of can manufacturers to light-weight their can offerings.  The increased flexibility of the light-weighted cans requires a more flexible internal coating and this innovation provides a solution.

Intellectual Property

The new coating was developed by AkzoNobel Packaging Coatings under the brand Aqualure®.

Consultant View

The new coating is an important aid to the aim of light-weighting food and drinks cans and is a good example of innovation in one area creating the need for subsequent innovations elsewhere in the supply chain.  Researchers should examine the REID database for other similar examples using search terms such as: "Light-weighting" ,  "alternative materials" and "Oxygen scavengers".
