These pouches typically use gold or silver aluminum foil laminated with various plastic layers, allowing the bag to stand upright on shelves.

The gold and silver foil provide an attractive, eye-catching look in addition to excellent barrier properties.

Aluminum provides a complete barrier to light, oxygen, and moisture, helping preserve food freshness and shelf life.

A main feature of stand up pouches is the press zipper closure. The press zipper provides an easy open and close mechanism while still keeping contents secure and fresh.

This zipper runs along the top edge of the pouch, allowing for easy opening and resealing. The press zipper closure keeps contents secure and fresh by providing a tight seal, preventing leaks and spills.

Yet it also allows for convenient access to the pouch contents with just a press of the fingers.

Aluminum stand up pouches feature a self-stand bottom gusset. This specially designed bottom allows the pouch to stand upright on shelves for attractive product display.

The gusset folds inward, creating a flat bottom surface. This gives the flexible pouch stability to stand on its own without any external support. The self-stand feature enables easy storage, transportation, and merchandising of the pouches.

The colored aluminum foils provide the same excellent barrier properties against light, moisture, and oxygen.

This maintains freshness and shelf life while allowing brands to incorporate color into their packaging for visual appeal. Color foils expand the packaging customization possibilities, enabling unique color combinations and gradients.

With multi-color foil printing, aluminum stand up pouches can align with specific brand colors and aesthetics. The color possibilities allow for creativity in design while maintaining the durability and functionality of aluminum foil pouches.

Coffee beans release a significant amount of carbon dioxide gas during the roasting process and continue to emit gas after roasting.

If this gas could not escape from the bag, it can build up pressure inside the bag and cause the bag to burst or the coffee to become stale or rancid.

A degassing valve is needed and typically placed in the front or back of the Mylar bag. The valve allows carbon dioxide gas to escape from the bag while preventing oxygen, moisture, and other contaminants from entering the bag.

Aluminum stand up pouches can be enhanced with a die-cut hang hole to maximize product visibility and accessibility. The hang hole is cut into the top of the stand up pouch, allowing the bag to be hung from pegs or hooks for display.

Hanging pouches directly on pegboards and racks keeps them upright, prominent, and easy to remove. This can be useful in retail environments where shelf space is limited.

The pouches can be tailored to fit the exact dimensions of the product being packaged. This helps minimize excess materials and prevents shifting inside the bag. The customized fit reduces wasted space and materials compared to using standard pouch sizes.

Pouches can be designed to hold everything from small granola portions to large bulk quantities. Custom sizing also allows for designing the ideal width and height for shelf display and consumer handling.
