Our custom PA/PE four side seal bags are engineered for demanding dry food and powder applications, leveraging the strength of PA (nylon) and the food-safe barrier properties of PE. The four-side sealed design delivers enhanced structural integrity, while the high-performance material offers superior puncture resistance and oxygen barrier performance to preserve product freshness, flavor, and shelf life—ideal for coffee powder, ground spices, instant mixes, and granular dry goods.
As a leading flexible packaging manufacturer with 8+ years of industry experience, we customize every detail of these bags to your product specifications, from material thickness to printing and functional add-ons.
- PA/PE High-Performance Construction: PA (nylon) layer provides exceptional puncture resistance, while the PE inner layer offers food-safe sealing and moisture protection, making the bags ideal for sharp-edged or granular dry foods.
- Superior Oxygen Barrier: Multi-layer structure minimizes oxygen transmission, preventing oxidation and preserving the freshness, aroma, and quality of sensitive products like coffee powder and spices.
- Four-Side Seal Durability: Fully sealed edges eliminate leaks and spills, ensuring the bags maintain structural integrity during storage, shipping, and handling.
- Customizable Branding: Supports up to 11-color gravure printing for high-resolution logos, product details, and vibrant designs—just like the coffee powder packaging shown, perfect for building shelf appeal.
- Food-Safe Compliance: All materials meet FDA, SGS, and EU food-grade standards, ensuring safe direct contact with dry food and powder products.
