Non Woven Aluminum Foil Insulated Three-dimensional Bag

Non woven aluminum foil insulated three-dimensional bag is a functional packaging container that combines the flexibility of non-woven fabric, the high reflection and insulation properties of aluminum foil, and the three-dimensional structure design. It is particularly suitable for scenarios such as food delivery, fresh food transportation, outdoor picnics, etc. Its core advantages lie in large capacity, strong stability, and significant insulation and cooling effects. Temperature isolation is achieved through a multi-layer composite structure (non-woven fabric outer layer+insulation layer+aluminum foil inner layer), while the three-dimensional bottom design enhances the load-bearing capacity and space utilization efficiency.

The bottom reinforcement design adopts a three-dimensional bag bottom with hexagonal or rectangular unfolding (such as patented design), which forms a stable support through hot pressing edge sealing or ultrasonic welding technology, and can stand independently, avoiding the problem of traditional flat bags easily tipping over.

After unfolding, the bottom area expands, and the capacity is increased by 30% -50% compared to the same size flat bag, suitable for loading irregularly shaped items such as cakes and seafood.

Detail optimization, widened non-woven handle (2-5cm) or webbing design, dispersed load-bearing pressure, reduced palm pressure strength by 37% when fully loaded with 10kg.

Some styles have built-in mesh bags or layered structures, which can be used to store accessories such as tableware and ice packs in different categories.

 

 

Unique advantages of three-dimensional bottom aluminum foil insulation bag
 Structural stability
Through the hot pressing edge sealing technology of the bottom and side plates (such as patented design), the bag can stand independently after unfolding, avoiding the problem of traditional flat bags easily collapsing, suitable for express packaging or shelf display.
The bottom adopts a hexagonal unfolding design (as patented), and the contents are fixed by adjusting blocks and pressure plates to prevent damage caused by shaking during transportation.

Space utilization
The three-dimensional bottom design expands the bottom area, increasing the capacity by 30% -50% compared to flat bags of the same size, and can accommodate irregular items such as whole boxes of fruits and multi-layer meal boxes.
Some styles come with built-in elastic bands or mesh bags to secure ice packs or separate ingredients, ensuring even temperature distribution.

Load bearing and durability
The bottom reinforcement structure (such as the combination of bottom plate and side plate in the patent) increases the load-bearing capacity to 10kg, making it suitable for loading heavy objects such as seafood and meat.
Ultrasonic welding has no pinholes on the edges, stronger sealing, and is less prone to cracking when reused.
