A new 1,000 litre bag designed for the filling of smaller formulations of bag-in-box applications will provide cost savings for processors of high value food products, says Arena Products.

The company said its goal is to provide the optimum liquid fill or discharge system so that its customers gain cost savings and operational efficiencies, while ensuring product protection.

“The introduction of the 1,000 litre bag was informed by customer demand for a smaller bag that would fit into their existing batch process with minimal change,”​ a spokesperson for Arena Products told

Standard bags for use in bag-in-box filling applications are designed to accommodate 1,250 litres of product, but Arena said that processors often need to create formulations in smaller quantities, especially for high-value products such as fruit fillings, diced tomatoes and sauces.

While these processors short fill the standard size bags with product, the new 1,000 litre bag enables better product protection, said the company, as a full bag is more stable than one that is short filled.

The company said that the smaller capacity bag is also less expensive than the standard size and it is designed to work with the Arena 330 (A330) Shipper Intermediate Bulk Container (IBC) Liquid Shipping System.

The introduction of the smaller formulation bag follows the recent addition of aseptic bags to the US manufacturer’s Air-Evac Bag-in-Box packaging system.

Arena said the use of aseptic packaging is growing in the industry as a result of the market's demand for better product safety.

The Air-Evac system aims to increase the amount of high viscosity fluids that can be extracted from bag-in-box packages and Arena claims that the aseptic-filling development enables greater efficiency and cost savings for processors.

"The aseptic process enables longer shelf-life for products and better manufacturing efficiencies for producers," ​said Mike Brunhuber, vice president of Arena Products at the time.

The aseptic, metallised film bags are available with a variety of barrier films to meet customers specific needs, said the company.
