This came from NGC's newsletter but applies to PCGS as well. Makes you wonder why PCGS hasn't addressed this and continues to let rumors fly while NGC explains:
It is extremely important to choose the proper way to package coins being sent to NGC for grading. Depending on the grading tier you have selected and the method of shipping, many coins can remain in their individual sleeves (flips, holders etc.) for up to 30 days before being encapsulated. This is all the time that is needed for coins to react with their containers or other contaminants. Many types of coin flips contain a chemical called Poly Vinyl Chloride or PVC. This chemical is what makes the plastic soft and bendable but it can also be quite damaging to coins. Over extended periods of time, PVC can actually corrode or eat into the surfaces of the coin. There are coin flips that are made with no PVC. Since these flips are much stiffer, they have the dual benefit of being non-corrosive and more protective of your coins from receiving hairlines or scratches. These non-PVC flips are the type that we highly recommend. They can be purchased at most coin shops or from most coin supply companies.
Please note that there are many negative conditions that can begin to affect your coins before they are received by NGC. A few examples are exposure to excessive moisture and humidity or improper dipping. These conditions can be accelerated during transportation since each shipment can undergo several temperature and humidity changes. Once your coins reach our facilities at NGC, they are stored in a secure environment that is both temperature and humidity controlled.

I think it is called customer service, something many companies are sorely lacking.

It's bizarre to me how many in the industry still use PVC flips despite their well-documented dangers. To me, if a coin is worth the effort to save at all, it's worth a few extra cents for a safe home.
