You can reinforce the front and back ends of your packaging by applying three film layers during the RoRo StretchPack® packaging process. This added reinforcement improves the film’s puncture resistance on sharp corners to keep a 6-sided sealed packaging.
High puncture resistance on product corner
The stretch hood film used in the RoRo StretchPack® packaging offers high puncture and tear resistance. It reduces the risk that the packaging film breaks during transport and handling, also when products have protruding edges. Even if the film breaks, it will not tear apart like more rigid film types tend to do.
Extra film layers on sharp corners minimize the risk
However, if your products have sharp corners, you can as an option apply two additional film layers on the front and back ends during the packaging process. This solution is beneficial on products with sharp corners, when retaining sealed and waterproof packaging throughout the whole logistic chain is essential.
A simple process without extra equipment
Applying three film layers on the product end is controlled by the RoRo StretchPack® packaging machine with an updated software – no additional equipment is required. The same stretch hood film tube used for the main packaging is also used to create the two extra reinforcement layers. During the process, the packaging machine folds the stretch hood film, while the conveyors move the product back and forth as its front and back ends pass through the machine. After packaging is completed, the film is sealed and cut in the standard way, ensuring a smooth and efficient workflow without altering the overall packaging cycle.
This solution is not intended to protect product corners from external impact. Instead, it is a way to reinforce the film layer to reduce the risk of film puncture which e.g. could cause ingress from moisture that could harm the product.
