Secondary-Packaging(Random Weight Packaging)

Secondary-Packaging Solution for Random Weight Products

In many food production environments, individual packs—such as small pillow bags of nuts, dried fruits, or candies—are not always uniform in weight. To meet retail packaging demands like 500g or 1kg combo bags, manufacturers need a precise secondary-packaging packaging solution that can intelligently collect and regroup these random-weight primary packs into a standardized, retail-ready secondary pouch.

Soontrue’s Secondary-Packaging (Random Weight Packaging) solution is specifically designed for this challenge. Our systems integrate vertical form-fill-seal machines or premade pouch machines with advanced multi-head weighers or counting modules. These units automatically select a combination of small packs that together meet the exact target weight, then repackage them into a secondary bag—ensuring minimal deviation, clean presentation, and full automation.

This approach is especially effective for “bag-in-bag” packaging of irregular items, enabling high-efficiency packing of snack mixes, seasonal assortments, or variety packs. It also supports SKU flexibility and quick changeovers between different products or bundle weights.

By automating the collection and repacking of random-weight bags, Soontrue helps you reduce manual sorting, eliminate under/overfilling, and optimize packaging accuracy across production batches.
