No permission transfers between tasks
No. The official Bacofoil ZIPPER All Purpose Bags page describes freezer use but explicitly says the bags are not suitable for microwave, combination or conventional ovens. The selected medium 12-pack belongs to that format. A freezer claim or dishwasher-care limit does not override the separate heating prohibition.
Read the exact maker warning
The maker lists PE plastic and medium width 27 cm, height 24 cm, quantity 12. The retailer lists 24 by 27 cm and 3 L. Those records help identify the selection, not approve every temperature or food task. We have not performed heating, migration, seal or freezing experiments, and do not assign an unlisted hot-fill limit.
Keep the selected format distinct
Do not use another Bacofoil product’s FAQ to reverse this restriction. Its cling-film microwave answer concerns particular PVC film and a separate Irish EasyCut PE example, not the ZIPPER bag. Brand name and polymer wording alone do not establish identical permitted use. Retain the product format and current country/version with every instruction.
Do not invent a heating workaround
For buying, look for a product whose actual current package supports the intended task rather than improvising a bag-heating method. If the received label or source version conflicts, stop the assumption and ask the maker. Our tool can retrieve the published prohibition, but it cannot approve an individual food-heating procedure.
A purchase case to keep explicit
A dishwasher statement is about cleaning under stated conditions;it is not proof that the same bag may be heated around food. The maker’s explicit microwave and oven exclusion remains decisive for this format. Do not infer permission from the PE material name alone.
