From an archive of a VERY old Flyertalk post:
KLM has introduced a new Service Recovery Package. The contents of the package, which will vary depending on the extent of the delay, include a letter of apology, a telephone card, a meal coupon, Flying Dutchman points or discount coupons for tax-free items, a discount coupon for a future KLM flight, and a questionnaire. With these product improvements, KLM takes another step forward in improving passenger service.
I guess it's some kind of hand-out if your flight is delayed or other related issue. The Flyertalk post is from 2002, and your link is from about 2007. Possibly things have changed since then.
Note that this was just the top result from a google search "service recovery package KLM" - I have no idea if it's the actual answer
