Pregis Films solves multipack problem for milk producer; helps bring new retail shrink multipack solution to market.
The Problem
A producer of premium milk was ramping up to introduce a new six pack 52-ounce plastic bottle pack to the marketplace. The new design was going to be distributed to big box stores, as well as supermarket outlets. In order to facilitate handling for both consumers and store personnel, the bottles are first tray packed, then shrink wrapped.
The absence or opening of the shrink-wrapped material on either side of the bundle, is known as a bullseye. The typical approach to heavier bundles is to lift by placing a hand in one or both sides to grab the overwrap within the bullseye. Therefore, it’s critical that the material be strong enough that it doesn’t tear or stretch in the process, sending the bottles spilling to the ground.
Unfortunately, when the milk producer was testing its shrink wrapped multipacks, it was experiencing frequent failures. The polyethylene (LDPE) material would either tear, or the wrap would shrink so tightly around the bottles, that it would compress and deform the primary packaging. The weight of the bottles and their profile added to the complexity and contributed to the failure of the shrink film.
