III. Food-Grade Composite Layer, Safe, Non-toxic, and Odorless
The inner layer of the bag uses a composite material that meets
food-grade standards. It is safe, non-toxic, and odorless, and can
directly contact food without concerns about migration or odor.
Food-grade adhesives and environmentally friendly inks are used in
the production process to ensure that the packaging material does
not affect the original flavor of the food. Suitable for products
with high food safety sensitivity, such as cookies, bread, nuts,
and coffee beans.
IV. Multi-layer Barrier Design to Lock in Moisture in Baked Goods
The packaging bag employs a scientifically designed multi-layer
barrier structure to effectively block air, moisture, and oil,
maintaining the freshness and consistent taste of the food. Whether
it's a moist baked good or a dry pastry, it provides excellent
protection. The barrier layers prevent moisture loss and slow down
drying, making it particularly suitable for baked goods such as
cookies, bread, and egg yolk pastries, providing a consistently
fresh experience during transportation, display, and storage.
V. Adjustable Window Size to Adapt to Coffee Bean/Powder Forms
The transparent window supports customization in size, shape, and
position, allowing for flexible design of the display area based on
product characteristics. For coffee packaging, the window ratio can
be adjusted according to the state of the beans or powder, allowing
consumers to more intuitively judge the product's freshness and
particle size. This not only enhances visual appeal but also
increases shelf competitiveness, making the brand stand out among
similar products.
