the smell will seep through and microscopic dust will be on the outside of it and dogs will smell it and nothing can cover the oder of weed to a dog so basically there is no way you will be able to do that if dogs are smelling it unless you use latex gloves and re wrap it like every hour until the smell seeps through what ever you put it in you should watch the video "nevergetbusted" it tells you all about how K9's sniff hope this answers your question
