Innovia Films has won its first commercial deal for its Propafilm RCU with German chocolate manufacturer, Halloren Schokoladenfabrik.

The BOPP film allegedly provides protection from mineral oil migration and is a barrier to water vapour, flavours and aromas.

Flow wrap

The film application is a flow wrap of the tray containing three flavours of Oh là là​ chocolates in a box: Marc de Champagne, Chocolat Noir and Crème de Nougat​.

FoodProductionDaily reported on the launch of the transparent Propafilm RCU film​ in January this year as it is the firm’s latest BOPP development and provides up to 1.5 years proven protection from mineral oil migration.

The findings are based on a study ‘Mineral Oil Barrier Testing of Cellulose-Based and Polypropylene-Based Films​’, by Gary O'Connor, analytical leader chromatography, Neil Hudson, team leader chromatography and Simon Buckley, analytical manager, who all work for Innovia Films.

The purpose of the study was to determine whether a selection of various coated and un-coated cellulose-based films and co-extruded and coated biaxially oriented polypropylene (BOPP) film types provided a functional MOH barrier.

Food packaging serves two primary functions: to preserve the food and to protect its quality from the point of manufacture to the point of use, the consumer​,” said Hudson.

Dried foods typically require preservation and protection for a minimum of 1.5 years. Selection of a film that will meet the moisture, oxygen and aroma barrier requirements for a particular food over that time period is paramount​.

1.5-year duration

Selection of functional barriers that will meet specific food protection and preservation requirements and provide a MOH barrier for a 1.5-year duration at typical room temperature storage conditions is the desired end point​.”

The coatings selected for the study were those commonly used with films that were in contact with food and included, polyvinyl dichloride (PVdC) and acrylic copolymer coatings. These coating layers are generally used to provide good gaseous barriers, heat sealability and printability to the food packaging.

Based in Halle (Saale), Saxony-Anhalt, and founded in 1804, Halloren Schokoladenfabrik is the oldest chocolate factory in Germany.

The Oh là là​ chocolate assortment was launched on the company’s stand at the International Sweets Exhibition (ISM) in Cologne, earlier this year.
