These custom PET/PE quad seal bags are a premium packaging solution for dry food and powder products like specialty coffee beans (such as the Kopi Luwak shown in the image). Constructed with a standard PET/PE barrier layer, they offer excellent oxygen and moisture resistance to extend shelf life, while the high-clarity PET outer layer ensures vibrant brand printing and product visibility.
The quad-seal (four-side sealed) structure provides exceptional seal strength and a stable, upright base, making these bags ideal for retail shelves and bulk storage. We customize every detail to your product’s needs, from size and thickness to functional add-ons like degassing valves for coffee.
- Standard PET/PE Barrier Layer: The dual-layer construction combines the rigidity and printability of PET with the moisture/oxygen barrier of PE, protecting dry goods and powders from environmental damage.
- High Transparency: The clear PET exterior showcases product details and brand designs, enhancing shelf appeal for retail-ready packaging.
- Superior Seal Strength: Quad-side heat sealing ensures no leaks or contamination, even for fine powders or oily products like specialty coffee.
- Customizable for Coffee & Dry Goods: Compatible with coffee degassing valves, tear notches, and resealable zippers to suit specialty food packaging needs.
- Vibrant Printing: Supports up to 11-color gravure printing for sharp, high-quality branding (like the golden and red design on the Kopi Luwak bags).
