For general packing ( I mail many books in bubble mailers the flaps of which I seal with this tape plus many cartons of books) this product does the job at low price. I don't think it's worth it to buy thicker tape: if I have a heavy job I just use more or add strapping at the extremities. Have used nothing else for approximately three years and to date have not been aware of any failure.
Sticks to tape gun & can be frustrating when packing items for shipping. However the cost is fair & it DOES stick well to boxes bubble wrap & other packing material.
