Bubble wrap marks?!

[Matrix6]

Everything I've ever received bubble wrapped have always had the bubble part facing the item. I think the twain being is that out protects item better with the cushioning against impact, the flat surface acts like skin which prevents sharper objects reaching into the item.

Factors that causes bubble wrap making may including poor quality plastic, heat, kept under bubble wrap condition for long periods and maybe even humidity and pressure!?

I normally wrap the item with sheets of foam/styrofoam (?) and then bubble wrap over it.
