Little details. An easier routine.

Twin-Track Double Click-Seal

Dual parallel tracks press shut corner-to-corner to form an airtight barrier that seals in freshness.

Deep Freezer Protection

Commercial-gauge heavy-duty plastic shields bulky joints and large prepped vegetables from icy freezer burn.

Stand & Fill Base

Expandable pleated bottom gives the bag a stable standing shape on the worktop so you can fill without holding.

Generous 9.1 L Volume

Twice the size of standard gallon bags, allowing large food items to pack naturally without straining seams.

Clear Food Visibility

Transparent heavy film keeps large contents and batch sizes clearly in view inside deep freezer drawers.

Dishwasher-Safe Longevity

Heavy-duty BPA-free plastic washes cleanly on the top dishwasher rack or with warm soapy water for repeated reuse.

Made for everyday possibilities.

Large Meat Joints & Whole Poultry

Fit large family hams, whole roasts, and large cuts without forcing seams or piercing edges.

Bulk Vegetable Prep & Farmers Market Hauls

Store trimmed squash, bulk bags of carrots, peppers, or greens fresh from the farm shop.

Double-Batch Family Preps

Pack multi-portion meal preps together in a single container for effortless weekend party catering.

Organised Household Essentials

Keep seasonal items or travel goods neatly gathered (reserve dedicated separate bags for non-food items).

Countertop Microwave Defrosting

Gently defrost larger pre-cooked food items with the top seal left wide open to vent steam.

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

Pack the biggest prep jobs without squeezing, straining, or spilling.

When a gallon bag is simply too tight, reach for the 9.1 L bag. Open the expandable Stand & Fill base completely and rest it flat on your counter. Place substantial portions of trimmed meat, whole roasts, or mounds of sliced soup vegetables inside with room to spare. Run your fingers firmly across both tracks of the Double Click-Seal until completely joined. Check the closure, then store flat or upright in your freezer.

Oversized capacity meets dependable commercial strength for stress-free bulk prep.

Forcing large cuts into undersized bags often causes burst seams and dried-out food. With an expansive 9.1 L capacity, this heavy-duty bag gives whole roasts and catering-sized batch cooking the room they require. The heavy commercial-gauge plastic and twin-track Double Click-Seal create an airtight barrier that locks out cold freezer air, defending your ingredients from freezer burn. It holds its standing shape on the worktop to make filling simple, then cleans up easily in the dishwasher for endless reuse.

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.

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.
