Brief Introduction: Combine the eco-friendly appeal of kraft paper with the moisture protection of PE film in our reinforced multi-wall bags, built for the toughest construction environments.
A premium dry-mix mortar brand wanted to maintain an eco-friendly 'natural' look using kraft paper, but they were plagued by moisture damage in humid storage conditions. Standard paper bags were simply not enough to protect the specialized additives in their high-end mortar products, resulting in significant stock loss.
Our solution was a custom Multi-wall Kraft Paper Bag featuring a '3-paper-1-film' construction. By sandwiching a high-density PE film between layers of heavy-duty extensible kraft paper, we provided a complete moisture barrier without sacrificing the traditional paper feel. The bag's high porosity allows air to escape during filling while keeping external humidity out.
The transition solved the moisture problem overnight, extending the product's shelf life by several months. The client’s customers—contractors and builders—appreciated the bags' toughness and the fact they didn't tear when dragged across job sites. This reliability helped the brand secure a long-term supply contract with a national construction group.
