My husband and I sell on ebay occasionally and some of our packages can be large and heavy. So we need a packaging tape that is strong and durable. We have tried many brands of tape trying to find an inexpensive tape that would do a good job. Unfortunately, this is one of those cases where you get what you pay for.
Scotch packaging tape costs more than most other tapes but it always does a good job. We have never had a package come open during delivery when using the Scotch brand tape. We always make sure to purchase the super strength high performance packaging tape and have been very satisfied.
You can buy Scotch packaging tape in single or multiple rolls. If we are doing a lot of selling, I will buy the multiple roll packs but when we just sell one or two items I like the single rolls that come with their own dispensers. It is so much easier to use the cutting blade on the dispenser and not having to use scissors to cut the tape. The single rolls usually cost around $4.00 which is reasonable.
I highly recommend Scotch packaging taope to anyone needing to ship a package securely.
