SANTIAGO, Sept 26 (Reuters) - Chile's Empresas Copec has entered the customer delivery services business by acquiring last-mile logistics firm Blue Express for about $225 million, the country's largest industrial group said on Monday.

Copec subsidiaries signed an agreement with Private Investment Fund BX and Blue Express to purchase 100% of Blue Express' shares, Copec said in a filing to Chile's regulator.

It said the deal, still subject to regulatory approval, would be financed through cash and debt from its subsidiary, Copec SA.

Blue Express did not immediately respond to a request for comment.

Blue Express provides logistics services for e-commerce and couriers through 1,000 reception and dispatch points in Chile, covering the costly step of shipping products just before it reaches the customer's door.

Empresas Copec has a network of 681 gas stations throughout Chile, serving over 1 million customers per day. (Reporting by Natalia Ramos; Writing by Kylie Madry; Editing by Josie Kao)
