Alcoa has announced that its Alcoa Closure Systems International (CSI) business is set to expand further into the $100 million dairy packaging business. The company has launched its new Seal-MAX 38mm screw-on/screw-off closure, which it believes marks a major advance in dairy packaging.

The Alcoa Seal-MAX closure has been designed to prevent leakage in milk containers, yet is easy to open and offers improved tamper evidence, said the company this week.

"The Seal-MAX closure is for the dairy producer who desires and values improved sealing," commented Jeff Birk, director of marketing for Alcoa CSI.

"With Alcoa CSI's package sealing expertise plus closure application experience, Alcoa can provide dairies with a sealing system that provides the optimal solution to eliminate package leakage. The Seal-MAX seal design is ideal for single-serve packages where sealing requirements are more stringent."

The Seal-MAX closure features Alcoa's patented Extra-Lok tamper band, which provides 'superior, consistent tamper evidence. The durable and sleek shell design reinforces the premium image of single-serve packages'.

Alcoa claims that lab tests and customer trials have been successfully completed to ensure the closure meets the needs of the dairy industry and adheres to the company's quality standards.

Alcoa's Seal-MAX closure is designed for single-serve to gallon sized HDPE and PET containers, and is available in a variety of colours.

Alcoa Closure Systems International (CSI), a subsidiary of Alcoa, provides closure and capping equipment products.
