Japanese help, what does this label/symbol thing mean?

Question

I brought this lunch box thing and there is this symbol that is like the recyling traingular sign, the one with 3 arrows. except this one has 2 arrows and instead of a triangle its a square. inside the 2 arrow square its has 'pu' followed by a small 'ra' and both is written in katakana. Thanks, hope you get what i mean

Answer 1

haha! cute.

that just means you can recycle it. "pura" in katakana, short for PLASTIC romanji. =]
