3D Aluminum Foil Bag – Key Advantages & Features
1. Unique 3D Stereo Cube Structure
The 3D Aluminum Foil Bag adopts a three-dimensional bottom design, providing real three-dimensional space for large equipment. It fits bulky and heavy goods perfectly without folding stress, realizing full surrounding coverage that flat bags cannot achieve.
2. Excellent Moisture & Oxygen Barrier Performance
Made of multi-layer aluminum foil composite, it has an extremely low water vapor transmission rate. It effectively blocks moisture, salt mist and oxygen, providing reliable protection against rust, oxidation and mildew for up to **3–5 years** in long-term storage.
3. Fully Customizable Dimensions
We support custom width, height, length and thickness to match any CNC machine, mold or industrial equipment. Each 3D Aluminum Foil Bag is tailor-made for a tight, stable fit, greatly improving packaging safety and efficiency.
4. Heavy-Duty & Puncture-Resistant Material
Thickened reinforced structure ensures high tensile and puncture resistance. It withstands friction, collision and stacking during transportation, avoiding tearing or breaking. Its durability is **3–5 times higher** than ordinary plastic bags.
5. Easy Sealing & Wide Compatibility
The bag supports heat sealing and adhesive tape sealing for good airtightness. It is widely used for equipment export, ocean shipping and warehouse storage, offering simple operation and all-round professional protection
