they are protected with chargeback 45days.
This is not true. There are many examples on this forum of people who believed this, sent paypal balance, and then didn't receive the bitcoins. Although in some circumstances it might be possible to chargeback, it is at least as likely that PayPal will simply close the accounts of both parties for violating the terms of service agreement, or that PayPal will refuse the chargeback for some reason.
Exchanging PayPal for bitcoin will generally result in one of the two people involved in the transaction being scammed.
If it turns out that you are not a scammer, and if you somehow get lucky enough to find someone who is not a scammer that is willing to buy the bitcoins from you, then you will pay a very high exchange rate for convenience of using PayPal.
You would be MUCH better off accepting cash or other irreversible payment methods with either a trusted escrow provider or in a face-to-face exchange. If you decide to use a trusted escrow provider, here is a list of popular escrow providers from this forum:
https://bitcointalk.org/index.php?topic=276897.0When working with a trusted bitcointalk user (for escrow as an example), be very careful to make sure that you are actually working with the person you think you are working with. There are scammers that will create similar looking usernames and use them to impersonate trusted individuals and trick people into sending them bitcoins.

PayPal Buyer Protection
Section 13 is amended to make several improvements to the PayPal Buyer Protection policy. The amendments will:
improve the conditions of reimbursement under PayPal Buyer Protection by:
i
ncreasing the time allowed for buyers to raise a Dispute from 45 days to 180 days from the date on which payment was made (UK resident PayPal users already benefit from this improvement); and
extending the range of eligible purchases to cover custom made items that are claimed to be Not Received.
for UK resident users contracting with PayPal under the User Agreement, clarify at new section 13.4.a.k that the purchase of any wager (whether by way of backing or laying against any outcome or otherwise) and any other opportunity to benefit from a gambling activity is not an eligible purchase.
for all users contracting with PayPal under the User Agreement, clarify at section 13.6 that, if PayPal has reason to believe that returning an item that the buyer claims is SNAD to the Payment Recipient would result in a violation of applicable law, such as laws related to handling counterfeit items, PayPal may report the item to a competent authority. This may result in the authority taking control of and/or possession of the item from the buyer and the Payment Recipient might not receive the item back.
