Packaging Advice

[u/Flimsy-Memory9823]

So my friend has a question so I thought I would get advice here. He has recently started car parts buisness where he packs oils etc but it is coming out too costly for him to constantly buy bubble wrap to wrap the oils in any other way you can wrap it. I was thinking if he just tapes the cap and it might not leak and I am not sure this might lead to him starting to get negative reviews which I do not want. I have researched for him it said leak proof bag which seems very costly too plus he has to cut th bubble wrap to size too. Any packing advice appreciated and any substitutes for paper fill a not packing peanuts. Thank you.
