I. Product Introduction The kraft paper windowed composite bag is a food-grade packaging
bag that combines natural texture, practical function, and a
high-end visual effect. The outer layer is made of high-quality
kraft paper, which is environmentally friendly, durable, and
provides excellent brand presentation. The inner layer uses a
high-barrier film or high-temperature resistant composite material
to ensure stable performance during transportation, storage, and
sealing processes. The transparent window design allows the
contents to be directly visible, enabling consumers to clearly
check the product's condition before purchase, effectively
enhancing shelf competitiveness. Suitable for a variety of products
such as coffee beans, baked goods, nuts, tea, grains, and pet
snacks, it is an ideal packaging solution for food brands,
e-commerce sellers, and bakeries. Various sizes, bag types, and
printing customizations are supported, allowing for a more
professional and recognizable brand presentation. II. Product Parameter Table | Item | Description |

III. High Temperature Resistant Composite Layer Adapts to
Post-Baking Heat Sealing Processes The inner layer of the bag is made of high-temperature resistant
composite material, capable of withstanding the heat filling and
heat sealing requirements of baked goods after baking, ensuring a
firm seal without delamination. This structure is particularly
suitable for use with heat sealing machines, continuous sealing
machines, and other equipment, ensuring stable packaging without
deformation or breakage even at high temperatures, providing a more
efficient and safer packaging solution for baked goods and coffee
bean processing. IV. Matte Surface Texture Prevents Oil Stains and Reflection The kraft paper outer layer features a natural, soft matte texture,
which not only enhances the product's visual appeal but also
effectively reduces reflection, improving shelf display. The matte
paper surface offers excellent oil resistance, preventing oil
stains from spreading even when packaging oily foods suchs as
cookies, nuts, and egg yolk pastries, keeping the packaging clean
and attractive. This textured style is more in line with the visual
style commonly used by high-end baking and specialty coffee brands,
making it highly attractive in the market. V. Precise Printing Positioning, Perfect Alignment of Graphics and
Windowed Displays Supports high-precision gravure printing, enabling precise
registration of patterns, text, logos, and transparent windows.
This allows brand elements to blend naturally with the windowed
display area, improving overall visual harmony. The shape and
content of the windows can be customized, such as coffee bean
shapes, ovals, squares, and large transparent areas, helping brands
showcase their products more three-dimensionally. Whether used for
e-commerce product detail pages, offline shelves, or gift box sets,
it significantly enhances the professionalism and recognizability
of the packaging. |
