If you've ever stood at your kitchen bin holding an empty bread bag, a crinkly chip packet and a scrunched-up ball of cling film, wondering where each one should go, you're not alone. These lightweight plastics are some of the most confusing items in the whole household. The good news is that many of them can now be recycled through New Zealand's Soft Plastic Recycling Scheme — but not all of them, and almost never through your kerbside yellow bin.

The single most important rule to remember is this: soft plastics do not belong in your kerbside recycling. The standardised yellow bin is for rigid containers, bottles, tins and paper only. Soft, scrunchable plastics jam up the sorting machinery at recycling facilities and cause real problems, so if you put a bread bag or chip packet in your yellow bin, it will simply be pulled out and sent to landfill — or worse, contaminate a whole load. Instead, soft plastics need to go to dedicated collection bins found at many supermarkets and retailers.

So which of our three items qualify? Bread bags are a clear yes — they're made from the same kind of stretchy polyethylene film that the scheme is designed to handle. A simple test helps: if you can scrunch it into a ball in your fist and it stays scrunched, it's likely a soft plastic that the scheme accepts. This covers bread bags, produce bags, bubble wrap, courier satchels, and the plastic wrap around toilet paper and drink bottles. Give them a quick shake or wipe to remove crumbs and food residue, keep them dry, and drop them into a store collection bin.

Chip packets and similar snack wrappers are trickier. Many of them are made from metallised or multi-layer plastics that feel foil-like on the inside, and these are much harder to recycle. The scheme's advice has changed over time and can vary, so check the current guidance at your nearest drop-off point — but as a general rule, shiny foil-lined chip packets are often not accepted and should go in your red general-waste bin. Plain, fully plastic snack bags may be fine if they pass the scrunch test.

Cling film is the awkward one. Technically it's a soft plastic, but in practice it's almost always contaminated with food, oils and grease, and it's so thin and clingy that it causes problems in recycling. For that reason cling film is generally not recyclable and should go in your red bin. The better move is to reduce how much you use it in the first place — reusable beeswax wraps, silicone lids, or simply a plate over a bowl all do the same job without the waste.

The practical takeaway: bread bags and other clean, scrunchable films are your soft-plastic recycling wins, so collect them in a bag under the sink and drop them at a supermarket bin. Treat chip packets with caution and check local guidance, and accept that cling film usually belongs in the rubbish. When in doubt, look for the collection points listed on the Soft Plastic Recycling Scheme website, and check with your local council, since services differ around the country.
