A thermoplastic bag includes structures that direct liquid away from areas of the bag more susceptible to failure and leaking. For example, one or more implementations include seals that direct liquid introduced into the bag away from comers of the bag. Additionally, one or more implementations include an insert positioned within the bag between the liquid directing structures such that the liquid directing structures direct liquid to the insert. In one or more implementations, the insert comprises an absorbent material. Thus, the liquid directing structures can direct liquid to a liquid absorbing insert.
