Product Introduction
The Kraft Paper Windowed Composite Bag is an environmentally
friendly packaging solution designed for brands in the baking, nut,
coffee bean, snack, and premium food industries. The outer layer
uses high-strength virgin kraft paper, presenting a natural and
rustic brand image; the visible window allows for a direct display
of the product, enhancing consumer trust and click-through rates.
The bag's composite structure combines aesthetics, protection, and
sealing, possessing excellent pressure resistance, barrier
properties, oil resistance, and moisture resistance, effectively
extending the shelf life of food. The window shape, size, and
manufacturing process can be customized to meet the diverse needs
of different brands. The entire bag meets food-grade safety
standards and can be used in various scenarios such as e-commerce

For moisture-absorbing and mold-prone baked goods, grains, and
nuts, the hygiene and antibacterial properties of the packaging are
crucial. This composite bag can be optionally fitted with an
antibacterial layer to effectively inhibit mold growth and reduce
the risk of spoilage due to humidity inside the bag. The
antibacterial layer is stable, safe, and non-migrating, providing
continuous protection during storage and transportation, extending
the shelf life of food, and providing brands with higher quality
assurance. Supports customizable irregular window shapes and 3D hot
stamping; food-grade safety; inner layer uses co-extrusion
technology
Kraft paper windowed composite bags can be customized with various
irregular window shapes and combined with high-end processes such
as 3D hot stamping to achieve a more impactful visual effect,
making the packaging stand out on shelves and in online product
displays. All materials meet food contact safety standards, are
free of fluorescent agents and harmful solvent residues, and are
suitable for various direct food contact scenarios. The inner layer
uses advanced multi-layer co-extrusion technology, reducing the
amount of traditional glue used, making the packaging more
environmentally friendly and stronger, and improving overall
barrier performance and heat-sealing stability.
