Little details. An easier routine.

Twin-Track Double Click-Seal

Dual interlocking tracks seal firmly together under fingertip pressure, keeping marinades and liquids safely contained.

Freezer Burn Protection

Thick commercial-gauge film forms an airtight shield that protects family-sized roasts and poultry from drying out.

Pleated Stand & Fill Bottom

Unfolds completely at the base so the bag stands open on your counter while you ladle and pack.

Visible Storage Design

Clear main body paired with a distinct blue lip makes spotting stored family dinners effortless on busy evenings.

Gentle Microwave Defrost

Move meals straight from the deep freeze into the microwave for gentle warming; just vent the top seal.

Easy Clean & Reusable

Wash inside-out with warm soapy water or run on the top rack of your dishwasher to reuse across countless weeks.

Made for everyday possibilities.

Family Batch Cooking

Hold complete multi-serving family meals, pasta bakes, and hearty dinner bases ready for busy evenings.

Bulk Poultry & Large Meat Cuts

Seal whole chickens, ribs, and bulk butcher cuts safely in the freezer without frost damage.

Fresh Bakery Loaves & Pastries

Protect artisanal bread, rolls, and sweet treats from going stale or absorbing fridge odours.

Prepped Soup Bases & Stews

Rest the bag upright on the worktop to load liquid-rich meal preps without spills or tipping.

Low-Heat Defrosting

Thaw frozen family meals directly in the bag at low microwave settings with the top unzipped.

A base that gives you a hand. XupZip product in use

Cook once on the weekend, and give the whole week a standing start.

When big batch cooking is bubbling on the stove, open the expandable Stand & Fill base and set the bag right on your counter. Scoop in large family portions of stew, cooked grains, or trimmed poultry with both hands free. Squeeze out excess air, press the twin tracks closed from edge to edge, and verify the seal is fully joined. Slide it flat or upright into the freezer, ready to pull down for a fast, wholesome dinner.

Spacious family food prep engineered to protect flavour and help keep worktops tidy.

Juggling family meal prep is hard enough without flimsy freezer bags tearing or tipping over. The generous 4.55 L capacity gives bulk butcher cuts and multi-serving bakes the breathing room they need. Thanks to the heavy-duty BPA-free plastic and twin-track Double Click-Seal, cold air stays out and natural moisture stays locked in, preventing the dry grey patches of freezer burn. Because the pleated bottom holds the bag upright, ladling remains spotless and your kitchen stays calm and collected.

Your kitchen. Your kind of storage.

A larger batch for the freezer. A smaller bag for lunch. A soup portion you can pour when you need it. The XupZip range gives different jobs their own size and closure, so you can build a storage routine around the way you shop, cook and eat.

Start with the bag you will use most, then choose the companions that make the rest of the week easier.

Our story

You hate the leak. You want the calm.

A bag leaks in your backpack. Lunch ends up where your books should be. It is a small thing that can spoil a whole day, and it is where the XupZip story began.

After too many messy accidents, the answer was to make everyday food storage more dependable: a secure closure, heavy-duty material and reusable bags that take the fuss out of storing and carrying the food you love.

From a Sunday batch cook to the lunch you take to work, the aim is simple: keep food fresh and the kitchen calm.

Zip in the fresh. Zip out the worry.
