What Makes Our 3 Side Seal Bags Stand Out?

Superior Barrier Protection

From the time they leave your facility until they get to your customers, your products need to be protected in packaging. The multiple layers of our lamination structures, such as PET/AL/PE, NY/PE, and Kraft Paper/VMPET/PE, make great shields against UV light, water, and oxygen.

The rates of water vapor and oxygen transmission are kept low by these materials. Longer shelf life for your products. You cut down on waste and make customers happier.

Versatile Design Options

Your brand deserves packaging that reflects its quality. We offer complete customization including:

• Custom sizes and shapes tailored to your product dimensions
• Up to 11-color printing for vibrant, eye-catching designs
• Multiple closure options like zipper seals and press-to-close mechanisms
• Functional features including euro holes for retail display and easy-tear notches

Our three-side seal design keeps the profile slim and flat while optimizing the space inside. This means that you'll use less room when shipping and storing your products, which will lower your logistics costs.

Advanced Manufacturing Quality

To make sure consistency, we oversee every step of the production process.

The pouches can handle tough conditions:

• Retort processing up to 121°C
• Cryogenic freezing temperatures
• Rough handling during transportation
• High-speed automated filling lines
