As mentioned above, "pink poly" bags and cushioning are simply static dissipative...there's quite a bit to watch out for with them obviously. What concerns me is your statement that "The pink bubble wrap is used to wrap PWBA that are bigger than those ESD bags that we ordered". This implies that you believe the two are interchangeable. They are not. The purpose of dissipative bags and metal coated/impregnated static shielding bags are different. Make sure you're using the right bag. Any PWBA with MOS semiconductors on it will be static sensitive. Using a shielded bag is important. They're orderable in just about any size. Dissipative "pink poly" bags are more often used to enclose non-static-sensitive devices/products (e.g., resistors/capacitors/transformers) that are packed or stored near static-sensitive ones.
