Wondering if anyone has run into good solutions for tamper evidence for product shipped in super sacks (1k and 2k varieties). Currently we tie the top of the super sack in a knot. I am currently considering using tamper evident tape and wrapping the knot, but that's kind of unprofessional looking even with my best attempts. I've also looked into using our truck seals around the knot, but hoping someone has run across something made for the purpose.
Thanks in advance for your suggestions
