Enhanced Food Protection Features
For moisture-absorbing and mold-prone products like baked goods, grains, and nuts, our composite bags can be equipped with an optional antibacterial layer. This effectively inhibits mold growth and reduces spoilage risk due to humidity. The antibacterial layer is stable, safe, and non-migrating, providing continuous protection during storage and transportation to extend food shelf life.
Customization & Advanced Manufacturing
We support custom irregular window shapes and high-end processes including 3D hot stamping for impactful visual effects that make your packaging stand out on shelves and in online displays. All materials meet food contact safety standards, are free of fluorescent agents and harmful solvent residues, and are suitable for direct food contact scenarios.
The inner layer utilizes advanced multi-layer co-extrusion technology, reducing traditional glue usage for more environmentally friendly and stronger packaging. This technology improves overall barrier performance and heat-sealing stability.
