Aluminum Foil Paper Bowl is 100% Grease proof and soy sauce proof

After 12 hours in freezer. Double PE coated, grease oil will permeate at the sealing part.

Becasue PE coated disposable kraft bowl can only grease proof for 30 miniutes to one hour.

If looking for non permeate, the aluminum foil paper container is the best choice.

But the aluminum foil paper container is expensive than the PE coated one.

All containers no matter kraft ones or aluminum foil paper ones, we only use paper material from TOP supplier in China- Sun Paper.

Sun paper material even 300g +18g PE is more sturdy and tough than other material 320g+18g PE.

It is about paper quality, not only about the paper weight.
