Is this warping normal?

Hi, I recently got into Warhammer and got myself a kill team starter which arrived in the mail today. I opened the box and saw several of the sprues are warped and now I'm worried. 2 of the plague marines and 5 of the angels of death's sprues are warped and I don't know if this will have consequences to the models.

The photos are of the most warped plague marine sprue.

I don't know what is or isn't acceptable for these things, so I decided to ask here for a second opinion. Is this warping normal?
