Explanation 1: Cockroach was introduced into packet by the manufacturing process
Assumptions:
Cockroach lived in a sealed bag without water:
False
Cockroach lived in a sealed bag without Air (Oxygen,Nitrogen) :
False
Cockroach is not a natural inhabitant of the neighborhood:
Questionable
Cockroach had no access into the bag:
False
Cockroach cannot climb a cupboard to the height at which the bag was stored at :
False
The following is logically obvious:
The cockroach would need air to breathe, water to drink
OP has no stated Entomology degree or education
Access to bag is True. An unsealed box lid is unlikely to present much of a barrier to a determined roach
Opening in bag is big enough to let the roach out, so it was big enough to let it in.
"Surfaces
Cockroaches Can Climb. Unfortunately, many of the materials used in home construction — wood, drywall, brick and stone — offer
cockroaches plenty of gripping surfaces, enabling them to
climb vertically and walk upside down on a ceiling " from a quick google search.
Explanation 2: Cockroach entered the bag after the box was opened and a hole cut in the bag
Assumptions:
Cockroach was able to get into bag through hole:
True (evidence in video) and if it came out through the hole, it could go in.
Cockroach was able to climb the cupboard:
True
Therefore, the simplest explanation is more likely seeing as the evidence of the assumption is wrong on many levels while the simpler assertions hold to be true.
Remedial action: Suggest OP climb off moral high horse and buy tupperware for sealing opened goods, at the very least get a washing peg.
