Smurfit Kappa Bag-in-Box has launched Safe Curve, a new type of “triple protection” seal on its wine application bags.
According to the company, in addition to the usual seals, Safe Curve's eight supplementary radial seals (two in each of the four corners) help to protect the wine inside.
The innovation is said to harmonise the manufacturing process and enable the consistent supply of products in case of any interruption.
Safe Curve has been made possible thanks to the installation of new tools on the production lines for wine bags in Smurfit Kappa’s plants at Ibi in Spain and Epernay, France.
Smurfit Kappa R&D manager Cendrine Lallement says: “We have developed these new seals in order to improve the filling process with severe constraints.”
The Safe Curve design brings additional protection during the drop of the bag into the box after filling, and also reduces the risk of abrasion if the filling conditions are not optimized, Smurfit Kappa says.
The risk of ears gluing and folding on box flaps or on the box closer is minimised, however if this does happen, the corner at risk is protected by a double seal.
“The bags are more resistant because the flow of the liquid is not on a sharp angle and the strength is maintained by the round shape,” the company says.
