Questions about these bags
Is the size inside the bag?
Sizes are measured flat (width x length). Allow a little extra on the width for the thickness of your item.
Can the bags be reused?
Yes. The press-to-close zip opens and closes by hand, so the bags can be used again.
Are the bags food safe?
Bags made for food are labelled food grade in the description, such as our stand-up pouches and vacuum bags. Check the description of the bag you're buying.
What does the pack size mean?
The pack size is how many bags come in one pack, for example 100 is a pack of 100 bags. "Number of packs" sets how many packs you get, so a pack of 100 with 2 packs is 200 bags.
Can I return the bags, or pick up my order?
Yes to both. We offer 90-day returns on unopened items (see our refund policy), and you can choose pickup at checkout and collect from Minto NSW or Braeside VIC, Monday to Friday 9am to 4pm.
