Use it for bakery loaves, poultry, prepared cuts of meat, or large batches of chopped soup vegetables.

Slide the clip smoothly across the blue track with two fingers. Inspect the seam to ensure it is shut before storing in the fridge or freezer.

Yes. The expandable bottom lets the bag sit upright on your counter while filling. When freezing liquids, leave room for liquid expansion as it freezes.

Both are 4.55 L bags with heavy-duty film. The Double Click-Seal bag closes by pressing the tracks together. This bag uses a blue Smart Zip slider, so opening and closing is a simple gliding motion.

Yes. Suitable for freezer storage and microwave thawing or gentle reheating. Leave the closure open to vent.

Little details. A calmer kitchen.

Good food storage should make the next step easier. From filling the bag to finding a portion in the freezer, these are the details you will use every day.

Airtight, leakproof ziplock

Keep the food in and the worry out. The Smart Zip slider closes the track tightly for fridge, freezer and everyday storage. Check it is fully shut before putting your bag away.

Freezer & Microwave Safe

Save a portion for another day, then thaw or gently reheat it when you need it. Leave the closure open in the microwave so steam can escape.

Heavy-duty material

A thicker, flexible bag for the groceries you bring home and the meals you make ahead. Built for regular food storage, rather than a single trip from the cupboard to the bin.

Easy opening

Two fingers and one smooth slide. Reach for the bread, fruit or prepared ingredients without pinching a closure together each time.

Easy to clean & reuse

Wash, dry and put it back into your routine. These reusable bags are dishwasher safe on the top rack, making clean-up one less job to linger over.

BPA-free food storage

BPA-free plastic for your everyday ingredients, from vegetables for tonight’s dinner to the sandwiches you are taking out tomorrow.

Multi Purpose Storage

One roomy bag. Plenty of everyday possibilities. Plan the meals you want to make, keep the ingredients together and give the food worth saving a place to stay.

Fruits

Keep berries and chopped fruit together, ready for breakfast bowls, lunchboxes or a smoothie from the freezer.

Vegetables

Put the fresh shop away in clear bags, or prepare a batch of chopped vegetables for the meals ahead.

Meats & fish

Separate your portions for the fridge or freezer so dinner starts with the amount you need.

Sandwiches

Pack the lunch you actually look forward to, and keep the rest of the loaf together at home.

Herbs

Give fresh herbs a place of their own so they are easy to spot when you are ready to cook.

Soups

Save a batch for another day. Open out the base before filling, close carefully and leave room for expansion when freezing.

Snacks

Gather nuts, crackers and other favourites for the desk, the car or a day away from home.

Vegetables being packed into a blue XupZip Gallon Slider bag beside its retail box

A place for the food worth keeping.

You have done the shopping. You have chopped the vegetables. You have made more of that favourite dinner than you need tonight. Now give it somewhere useful to go.

Open out the expandable base and the bag stands while you pack, leaving less to juggle on the counter. The 4.55 L size gives larger portions, bakery items and batches of ingredients room of their own. Slide the blue Smart Zip across the track, check the closure and put tomorrow’s food away.

Less fuss at the end of cooking. Something good to reach for when the next meal comes around.

Open the fridge. See a plan.

A little preparation today can make tomorrow feel easier. Keep the vegetables for dinner together, save the leftovers you want to eat again and put your next smoothie’s fruit where you can find it.

The clear bag lets you see what you have before you start searching. Add a label with the contents and date, and the batch you made on Sunday is easier to recognise later in the week. Instead of a forgotten portion at the back of the fridge, you have a meal waiting for its turn.

Use the same bag for fridge storage, freezer preparation and microwave thawing or gentle reheating. Leave the slider open when heating, then let the food fit around your day.

Fresh food, ready for the next plan.

Put the fresh shop away.

Keep chopped vegetables together, ready for tomorrow’s dinner.

Breakfast, already sorted.

Keep berries and chopped fruit together for breakfast bowls, lunchboxes or a smoothie.

Lunch packed. Plans made.

Pack a sandwich and a few favourites for the day ahead. The 30-bag retail box is shown; choose your box option above.

One bag. Back in the routine.

You finish the lunch. You wash the bag. You use it again. Reusable storage turns a throwaway habit into something you can keep reaching for, whether it is tomorrow’s sandwiches or the next batch of freezer portions.

The easy-to-clean plastic can be washed by hand or placed on the dishwasher’s top rack. Dry the bag before putting it away, ready for the next shop.

PEOPLE WHO STOPPED BUYING THE SUPERMARKET ROLL

★★★★★

“I originally bought these ziplock bags for their large size to store my tortilla wraps. The packaging they come in from my supermarket is no longer resealable [...] which made me resort to sealing them with tape, but the wraps went stale far too quickly. These bags have been a game-changer. The wraps fit perfectly inside and stay fresh for weeks on end.”

“Excellent size and value. Perfect for my needs which is to separate all the Lego pieces into separate colours. The zips make this an easier task going forward.”

The XupZip food-storage range alongside a woman preparing vegetables in the kitchen

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.

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.
