Free standard UK delivery on orders £35+ after discounts.
Can I microwave and defrost food in this bag?
Yes, for gentle defrosting and reheating. Always leave the top seal open before heating to let steam vent safely. Do not boil or use under high grill settings.
Can I wash this in the dishwasher?
Yes. Reusable XupZip® bags are top-rack dishwasher safe on gentle cycles. For maximum longevity across repeated uses, turn inside out, wash with warm soapy water, and allow to air dry.
Does this bag have a slider?
No. This bag uses the Double Click-Seal pinch closure. Press the two interlocking tracks firmly closed from edge to edge for an airtight barrier. If you prefer a sliding clip for effortless opening, choose the Smart Zip Slider range.
Does it prevent freezer burn on meat?
Yes. The heavy commercial-gauge film and dual interlocking tracks create an airtight barrier that helps protect bulk meat, poultry, and batch cooking during freezer storage.
Little details. An easier routine.
Airtight Double Click-Seal
Dual interlocking pinch tracks press closed edge-to-edge by hand to create a dependable, liquid-tight barrier that locks out air.
Deep Freezer Protection
Commercial-gauge heavy-duty film shields poultry, bulk cuts, and batch cooking from moisture loss and icy freezer burn.

Clear-lip flat-base bags suit stacking. Green-lip expandable-base bags are designed for Stand & Fill.
Clear Food Identification
Transparent body keeps contents instantly visible in crowded fridges so you never have to guess what you saved.
Microwave & Defrost Ready
Safe for gentle defrosting and low-heat reheating directly from chilled; just leave the top seal unzipped to vent steam safely.
Top-Rack Dishwasher Safe
Turn inside out and run on a gentle cycle, or wash by hand with warm soapy water and air dry for dependable reuse.
Made for everyday possibilities.

Protect steaks, chops, and diced chicken breasts securely in the deep freeze without frost damage.

A calm, orderly fridge with zero food prep wasted.
Tackle the evening food prep without fighting messy bags or flimsy film. The green-lip option has an expandable Stand & Fill base for filling; the clear-lip option has a flat base for stacking. Spoon in your cooked meal portion or prepared cuts. Press the dual tracks firmly together from corner to corner until you feel them join. Pop it straight onto the freezer shelf or pack it for tomorrow's lunch. At the end of the day, wash it on the top rack, air dry, and pack again.
Everyday freshness, sealed with confidence.
Designed for real family kitchens, from crisp salad greens to organised freezer batching and packed lunches.
Airtight salad & produce
Keep salad leaves and chopped vegetables together. Press both tracks of the Double Click-Seal shut before storing.

Fresh sandwiches to go
Pack a sandwich and a few favourite snacks together, ready for lunch at work or school.
Cook with intention, reduce prep chaos, and keep every portion tasting fresh.
A calm kitchen begins when food has a dependable place to stay. Built with heavy-duty commercial plastic and twin interlocking pinch tracks, this half-gallon bag locks in natural moisture while shutting out cold freezer air. That means batch-cooked stews and tender meat cuts emerge after freezing with their texture and flavour fully intact. The green-lip option has an expandable Stand & Fill base; the clear-lip option has a flat base for stacking. The bags clean in the top rack, so you spend less time wiping worktops and more time enjoying meals made ahead of time.
