They weren't repackaged.
The Mint issued a number of such envelopes and cards for circulation coins (change) as a prequel for the 2017 coins.
The official 150 logo is the multi coloured maple leaf which does not appear on any of these envelopes or cards, but is seen with 2017 coins.
The bubbly leaf is one of the Mint's logos as is the stylized 150, both are for promotion of Mint products only.
