Carrier bags or other bags (Mereoak Park RG2)

Hi Guys , I am a volunteer at New Beginnings in Reading and we have a community fridge where we give out food to anyone who is in need , homeless especially but also for anyone who is in need. I am looking for carrier bags or similar bags that we can give out food to people as many of them turn up without bags and we are struggling to provide for them. If anyone can help with any kind of bags, that would be much appreciated. Thank you 😊
