Manufacturers of Alseco Aluminum Milk Bottle Hoods & Caps. Dairy Packaging.

Alseco Milk Bottle Caps are made from pure, durable Alcoa Aluminum Foil of sufficient thickness and strength to do well the work for which they were intended. No germs, dust or foreign matter can get in, but equally important during delivery, none of the contents can get out. No matter how the bottle is tilted, no matter what handling it receives, Alseco Caps are absolutely safe to use. They cannot leak or get 'soggy'. You can be sure that your product will reach its destination and its original quality and in full measure. Once delivered, the aluminum caps are tamper-proof. A simple twist of the hand removes the cap from the bottle, without destroying its usefulness as a re-closure in the household, yet it is practically impossible for anyone to meddle with the cap without leaving a tell-tail evidence. Physical protection is combined with sanitary protection to the satisfaction of both the dairy and the customer.

Has product images, description, application and specifications provide product details.
