Zipper Bags for Frozen Foods

When using zipper bags for frozen food, the biggest challenge is ensuring the bag can withstand freezing temperatures without cracking or losing its sealing capability. Are materials like BOPP a good option, or are there other better alternatives? What materials would you say should never be used for frozen food zipper bags?

BOPP laminated with LDPE is OK for frozen food under -18 Celsius.
PET laminated with LDPE is also OK.
BOPA is much better than BOPP and PET for frozen usage, also it's OK for vacuum and frozen at the same time.
But CPP is not good for frozen usage, it's so easy to be broken under -18 Celsius, not matter it's laminated with BOPP or PET.
