The Cubi Pak: Two Pouches, One Smart Solution for RTD Nutrition

Most packaging innovation is incremental — a better film, a cleaner zipper, a tighter seal. Now and then someone changes the shape of the problem instead. That's what Arranti's Cubi Pak does.

Two pouches. One smart solution. Connected, convenient, distinct.

What the Cubi Pak Actually Is

The Cubi Pak takes two — and where the program calls for it, up to four — flat-bottom liquid spout pouches and joins them into a single connected unit. It ships as one. It merchandises as one. And a perforated center means the consumer can tear the pouches apart the moment they want a single serve, or keep them together as a bundle.

Every pouch carries a resealable spout for easy, leak-resistant pouring, a tear notch for easy-open access, side gussets for strength and capacity, and a flat bottom that stands the pack upright on shelf. The premium matte finish gives graphics somewhere to land.

Built for Ready-to-Drink

RTD is the fastest-growing corner of sports nutrition and the most punishing on packaging economics. Bottles and cans are heavy, expensive to ship full, and increasingly awkward to defend on sustainability grounds. The Cubi Pak carries liquid in a high-barrier flexible structure that uses a fraction of the material, ships flatter, and still stands square on a retail shelf or a refrigerator door.

• Protein shakes and RTDs — full flavour and aroma barrier, resealable spout, no rigid freight penalty.
• Multi-serve concentrates — controlled pouring with a spout instead of a screw-cap jug.
• Bundle offers — two-for pricing built into the pack itself rather than assembled with shrink film.
• Meal replacements, functional beverages and pet nutrition — anywhere a liquid needs protection and portability.

Ships as One, Sells as Two

Because the pouches arrive connected, secondary packaging is often unnecessary — no shrink wrap, no carrier board, no extra pick line. That's fewer components, fewer purchase orders and a cleaner sustainability story, while the shopper still perceives two distinct servings.

For two-part or reactive formulas that need real separation until the moment of use, the companion format is Arranti's patented dual chamber pouch.

Maximum Shelf Impact

Two connected pouches occupy roughly double the facing of a single unit, and the flat-bottom structure keeps them upright and square rather than slumping. More visibility, more presence, more sales — with print surfaces on every panel for hero branding, usage instructions, ingredient transparency and a serialized QR code linking the pack to live product data.

Strong, Light and Recyclable by Design

High-barrier film protects freshness and flavour and keeps moisture and contaminants out. The structure uses less material than rigid alternatives, so you ship more product per pallet and leave less waste behind. Recyclable mono-material constructions are available where the brand or the retailer requires them.

Who Should Be Looking at It

RTD and functional beverage brands under pressure on freight and plastic. Nutrition companies launching liquid line extensions without committing to bottling tooling. Subscription and club-channel businesses where pallet efficiency decides whether the margin works.

Getting Started

Arranti engineers the Cubi Pak around the fill: number of connected pouches, film structure, spout size, volume and print. Because it's a flexible structure rather than a moulded one, the path from concept to printed, delivered packaging runs in weeks rather than the quarters rigid tooling demands.

If your product ships as two bottles, stop paying to ship the bottles.
