How to choose the right size
- Measure the contents in width, length and, for thick items, height.
- Rule of thumb: allow 10 to 20 mm in width and length; for zip and sealed edge bags, also leave room for the closure.
- Angular or heavy items: choose a thicker film, see Film thickness in µm.
- Food: only bags marked for food contact, see Food-safe explained.
