So today I bought a package of kitchen shears to replace a pair that fell apart...They came in a blister pack...you know what I needed to open them :)
In googling bubble/blister pack for the correct term I came across this in Wikipedia...note the comment in parentheses:
"A hinged blister is known as a clamshell, used for a variety of products. It can be used as a security package to deter package pilferage for small high-value items, such as consumer electronics. It consists of one sheet folded over onto itself and sometimes fused at the edges. They can be securely heat sealed, making them difficult to open by hand to deter tampering. A pair of scissors or a sharp knife is often required to open them (although these are often sold in similar packages).[4] Care must be used to safely open some of these packages, as 6,000 Americans are sent to the emergency room each year by injuries suffered in opening such packages.[5][6] Wrap rage is sometimes the result."
