Frangible Seal Pouches: Ready-to-Mix Ingredients

Frangible seal pouches, multi-compartment pouches, or as our engineering staff likes to refer to them – Frangible Seam Pouches – are a unique packaging delivery method in which at least two components must be mixed together to create a functional product. Frangible seal pouches were created for industrial customers with challenging single or multiple-component packaging requiring separation until use. Frangible seal packaging is ideal for operations that require pre-measured liquids, gels, or powders to be stored separated until use. The ingredients are then mixed right in the pouch to activate and dispense on site.

Why do package engineers call them “Frangible Seam Pouches”?

The key to this type of pouch technology is the frangible seam that is different from the outer seams of the overall pouch. (See Fig 1)

How Does a Frangible Seam Work?

The internal frangible seam requires deliberate pressure to burst the interior weld between the two components, allowing for mix-in-the-bag activation. Contents are kept separate until mixing is required, allowing individually packaged components to remain inert and stable until a perfect mix is made during use.

Any combination of ingredients can be used, such as two-part epoxies, or a powdered product with a liquid activator. Each component is kept separated until pressure is applied to burst the seal separating the contents.

Mixing components is as easy as rolling the contents of the pouch toward the frangible seal, applying pressure to rupture the internal frangible seam, mixing the contents with each other to activate, then using a dispenser tip, spout, tear notch, or cutting the corner to allow the activated components to release in as precise a manner as required by your operations.

Spout options are widely available.

IMPAK Frangible Seal pouches are manufactured with multi-layer barrier films offering high chemical resistance to contents. Each pouch system keeps the contents pre-measured and separate until application. This allows for easy dispensing and accurate mixing.

Frangible Seal Pouch Sizing:

Frangible Seal pouches are available in various one, two, and three component liquid, paste, and powder systems. Our manufacturing operations allow for multiple types of clear unprinted Frangible Seal pouches available for shipment, or custom-made packaging in various sizes.

Standard IMPAK Frangible Seal Pouch

The material structure for this pouch (PAKVF46MCP) is 4.0 mil thick film foil and polypropylene, specifically designed to work in situations where the final product may cause layer separation or structure delaminating. Moist towelettes, oil, or alcohol impregnated media, essential oils, incense, and cosmetic products are all excellent candidates for this structure. The foil layer provides strong moisture barrier properties for both dry and wet products.
