CUSIP NO. 162825103

Item 4. Purpose of Transaction.

MMI Investments and MMI Plus purchased the Shares as part of their investment activities based on their belief that the Shares, when purchased, were undervalued and represented an attractive investment opportunity.  Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase of additional Shares desirable, the Reporting Persons may endeavor to increase their respective positions in the Issuer through, among other things, the purchase of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

On June 1, 2011, MMI Investments sent a letter (the “June 1 Letter”) to the Board of Directors of the Issuer (the “Board”) stating that it has grown increasingly frustrated with the Issuer’s poor valuation and share price performance and expressing its belief that the Issuer is trading at a valuation dramatically below its intrinsic worth and what it could command in a sale.  In the June 1 Letter, MMI Investments also expressed its belief that the obstacles to the Issuer’s fair valuation, including its awkward positioning as a small cap company and weakness in capital spending by its retail customer base, are likely insurmountable as long as the Issuer remains an independent public company, irrespective of the efforts of the Board and management.  MMI Investments therefore strongly urged the Board to retain an investment bank for the express purpose of exploring all strategic alternatives to maximize shareholder value, including a sale of the Issuer.  A copy of the June 1 Letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

On August 10, 2011, MMI Investments sent a letter to the Board (the “August 10 Letter”) reiterating its belief that the Issuer is significantly undervalued and that the Board should immediately hire an investment banker to assist the Board in seriously and comprehensively reviewing all strategic alternatives to maximize value for shareholders, including a sale of the Issuer.  In the August 10 Letter, MMI Investments expressed its belief that the Issuer’s poor share price performance, capital allocation and operating results over the last decade are indicative of a Board that has been a very poor steward of shareholder capital over the short and long terms.  MMI Investments questioned whether the Board is taking the Issuer’s undervaluation or shareholders seriously enough given that the Board, on three separate occasions, dismissed MMI Investments’ highly constructive recommendations to the Board, all with the goal of improving the Issuer’s dismal stock price performance.  Specifically, the Issuer had previously dismissed MMI Investments’ (1) recommendation that the Issuer hire an investment banker to explore strategic alternatives, (2) attempt to connect the Issuer with those who are highly qualified and potentially interested in buying the Issuer, and (3) request that one MMI Investments representative be voluntarily appointed to the Board.  MMI Investments also questioned the source of the Board’s confidence in and its commitment to the Issuer’s current strategic plan in light of the Issuer’s poor performance in stock price, operations and strategic planning.  A copy of the August 10 Letter is attached hereto as Exhibit 99.2 and is incorporated herein by reference.

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon completion of any of the actions discussed above. The Reporting Persons intend to review their respective investments in the Issuer on a continuing basis and engage in discussions with management and the Board concerning the business, operations and future plans of the Issuer and ways to enhance stockholder value.  Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their respective investments in the Issuer as they deem appropriate including, without limitation, seeking Board representation, making proposals to the Issuer concerning changes to the capitalization, ownership structure or operations of the Issuer, purchasing additional Shares, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares or changing their intention with respect to any and all matters referred to in Item 4.

CUSIP NO. 162825103

Item 5. Interest in Securities of the Issuer.

(a)-(b)     The aggregate percentage of Shares reported owned by each Reporting Person is based upon 40,098,852 Shares outstanding as of July 27, 2011, which is the total number of Shares outstanding as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 3, 2011.

As of the date hereof, MMI Investments directly owned 2,055,800 Shares, constituting approximately 5.1% of the Shares outstanding.  MMI Investments has the sole power to direct the vote and disposition of such Shares on the date of this statement.  As of the date hereof, MMI Plus directly owned 2,400 Shares, constituting less than 1% of the Shares outstanding.  MMI Plus has the sole power to direct the vote and disposition of such Shares on the date of this statement. MCM does not directly own any Shares. However, by virtue of being the general partner of MMI Investments and MMI Plus, MCM may be deemed to be the beneficial owner of the Shares owned by MMI Investments and MMI Plus and to have sole power over the voting and disposition of such Shares as a result of its having the sole power to make voting and disposition decisions on behalf of MMI Investments and MMI Plus with respect to such Shares.  MCM disclaims beneficial ownership of such Shares.  Mr. Lifflander does not directly own any Shares.  However, as a member of a “group” for the purposes of Rule 13d-5(b)(1) of the Securities Exchange Act of 1934, as amended, Mr. Lifflander may be deemed to beneficially own the Shares owned by MMI Investments and MMI Plus.  Mr. Lifflander disclaims beneficial ownership of such Shares.

Except as described above, as of the date hereof, to each Reporting Person’s knowledge, none of the persons listed on Schedule I owns any Shares or has any right to acquire, directly or indirectly, any beneficial ownership of Shares.

(c)           Except for the open market transactions in the Shares by MMI Investments and MMI Plus set forth in Schedule II attached hereto and incorporated herein by reference, there have been no transactions with respect to the Shares during the past 60 days by MMI Investments, MMI Plus, MCM or Mr. Lifflander, or, to each Reporting Person’s knowledge, any of the persons listed on Schedule I.

(d)           No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, such Shares.

(e)           Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

On August 10, 2011, the Reporting Persons entered into a Joint Filing Agreement in which the Reporting Persons agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to securities of the Issuer, to the extent required by applicable law.  A copy of this agreement is attached hereto as Exhibit 99.3 and is incorporated herein by reference.

Other than as described herein, there are no contracts, arrangements, understandings or relationships among the Reporting Persons, or between the Reporting Persons and any other person, with respect to the securities of the Issuer.

Philadelphia, Pennsylvania 19103

Dear Members of the Board:

As some of you know, MMI Investments, L.P. (“MMI”) has been a substantial investor in Checkpoint Systems, Inc. (“Checkpoint”) for nearly a decade.  MMI today owns 1,820,800 shares, or roughly 4.5% of the outstanding stock.  We have long admired Checkpoint’s market positions, technologies and strong cash flows, even as we have grown increasingly frustrated with its poor valuation and stock price performance.

In our time as investors there have been periods of good operational and stock performance, but not on a sustainable basis.  Checkpoint stock is today roughly unchanged, or below, its levels of one, three, five and seven years ago.  As it has for so long, Checkpoint trades today at a valuation we believe to be dramatically below its intrinsic worth and what it could command in a sale of the company.  There are many reasons for this, ranging from Checkpoint’s awkward positioning as a small cap company with limited natural comparables and institutional coverage, to the seemingly perpetual weakness in capital spending by its retail customer base.  While these factors may fluctuate, we have concluded that the obstacles to Checkpoint’s fair valuation are, in total, likely insurmountable as an independent public company, irrespective of the efforts of the Board and management.  Therefore we strongly urge the Board to retain an investment bank for the express purpose of exploring all strategic alternatives to maximize Checkpoint shareholder value, including a sale of the company.

We believe that Checkpoint’s strong market positions and technologies make it a highly attractive acquisition candidate for several well-capitalized potential strategic acquirers in competing and adjacent positions.  Moreover Checkpoint’s high levels of recurring cash flow make it a strong candidate for a leveraged buyout.  Either outcome is likely in our view to generate a substantial premium over the present stock price, and far more likely to do so than staying-the-course as an independent public company.

We have always endeavored to be constructive contributors to Checkpoint’s prospects for success, from encouraging greater focus on RFID in 2003 to our view today that shareholder value can best be maximized through a strategic alternatives review.  We recognize that the Board has likely considered this issue in the past, but we note that rarely has the M&A market been this robust due to historically low interest rates, liquid credit markets, tepid economic growth and the tremendous capital reserves of corporations and financial sponsors.  However, these attractive conditions will not last forever and the presently robust M&A window will eventually shut, as it did for several years during the recent credit crisis.  We strongly urge you to grasp this opportunity now to maximize value for Checkpoint shareholders.  We would be happy to discuss these matters in greater detail.  Please feel free to contact me at (212) 586-4333 or jlande@millcap.com

Sincerely,

/s/ Jerome J. Lande

The Board of Directors

Checkpoint Systems, Inc.

C/O Mr. Robert van der Merwe

Chairman & Chief Executive Officer

One Commerce Square

2005 Market Street, Suite 2410

Philadelphia, Pennsylvania 19103

Dear Members of the Board:

MMI Investments, L.P. (“MMI”) owns 1,960,800 shares of Checkpoint Systems, Inc. (“Checkpoint” or the “Company”), or roughly 4.9% of the outstanding stock, making us one of Checkpoint’s largest shareholders.  As you know, we have been a Checkpoint shareholder for roughly a decade.  Very shortly we will own more of Checkpoint and will file with the SEC a Schedule 13D disclosing additional information about our position as well as details regarding the communications we have had with the Board and Chairman & CEO Rob van der Merwe over the last few months.  We feel that Checkpoint is significantly undervalued given its strong products, technology, market positions and customer relationships.  The Board appears not to recognize that correcting that undervaluation will take more than the status quo.  We believe that view does a disservice to Checkpoint shareholders, and we hope therefore that this public disclosure will be illuminating and constructive.

Three separate times since June 2011 MMI has, on a private basis, proffered highly constructive recommendations to the Board, all with the goal of improving Checkpoint’s dismal stock price performance.  We have recommended that Checkpoint hire an investment banker to explore strategic alternatives, which the Board summarily dismissed.  We have attempted to connect Checkpoint with those who are highly qualified and potentially interested in buying the Company, to no avail.  Most recently we have requested that one MMI representative be voluntarily appointed to Checkpoint’s nine-member Board so that we could discuss these issues with full information, on an equal footing with the rest of the Board, so as to best represent the interests of our fellow shareholders.  The Board responded that it was uninterested in shareholder representation on the Board.  Instead, it repeated an offer of only entering into a confidentiality agreement that we had already declined due to our belief that it would effectively tie our hands without any compensating influence.  All of this, as well as Checkpoint’s long-term poor performance, lead us to question whether the Checkpoint Board is taking Checkpoint’s undervaluation or shareholders seriously enough.  Apparently we are not the only ones who feel this way, as is evident from the 2nd quarter earnings call during which Checkpoint’s largest shareholder questioned whether Mr. van der Merwe should resign and whether Checkpoint should sell itself.

For the Board’s benefit, allow me to explain why the situation is so serious.  As of August 5th, 2011, the total return of Checkpoint stock is negative over each of the one-, two-, three-, four-, five-, six-, seven- and eight-year timeframes.  The average decline over these timeframes is -24%.  Checkpoint has also underperformed the S&P 500, as well as both small cap indices of which it is a member: the S&P 600 and the Russell 2000, over every timeframe from one-year to ten-years.  The underperformance relative to these indices over these timeframes has annually averaged -35%, -60% and -52%, respectively.  This stock performance is abhorrent, and largely reflective of operating performance, both short- and long-term.  Checkpoint’s LTM adjusted EBITDA is lower than annual EBITDA has been in every fiscal year of the last decade other than 2006, and is roughly -25% below 2001.  Free cash flow for the LTM period is roughly 1/9th the level of 2001, and the lowest in the last decade, barring 2010 when free cash flow was actually negative.  Management has spoken extensively about the sizeable capital expenditures for ERP consolidation in 2010 and 2011, but even adding these back would still leave 2010 and LTM free cash flow at anemic levels compared to most fiscal years of the last decade.  These results were produced despite investments in growth during this decade of roughly $600mm, (defined as capital expenditures, research & development expense and acquisitions, not even including 2011’s acquisition of Shore to Shore, Inc.) or more than Checkpoint’s current market capitalization.  We believe these results are indicative of a Board that has been a very poor steward of shareholder capital over the short and long terms.

As the Board stated in refusing MMI’s recommendation to hire a banker and explore strategic alternatives, the Board is committed to the strategic plan Checkpoint is pursuing.  We wonder whether the Board was equally confident in the strategic plan presented by Checkpoint’s management in late November of 2008 (two months after Lehman failed and the credit crisis began), which projected 10% annual revenue growth and at least 10% operating margin by 2011.  We note that 2011 operating margin year-to-date is 1.8%, recently-lowered 2011 guidance calls for only 7.4% to 7.8% operating margin, and LTM and 2010 revenues are below 2008 and roughly the same as 2007.  What level of confidence did the Board have in the strategic plan management unveiled in 2005 that called for 15% operating margins by 2007?  Operating margins since 2005 have averaged less than half that goal.

With such poor performance in stock price, operations and strategic planning, how does the Board derive its confidence in the present strategic plan’s ability to reverse this decade-long trend, let alone the view that the strategic plan is a better alternative than engaging with bona fide potential acquirors, financial and strategic, certain of whom we believe have attempted in vain to discuss a transaction with Checkpoint?  Our analysis suggests that such a transaction could yield a stock price in the low-to-mid $20’s, assuming acquisition by a financial sponsor at 7.5x to 8.5x the midpoint of the Company’s 2011 EBITDA guidance, and potentially well above that with a strategic acquirer.  These are sincere questions, and we welcome any credible attempt to answer them.

We reiterate our view that Checkpoint should immediately hire an investment banker to assist the Board in seriously and comprehensively reviewing all strategic alternatives to maximize value for Checkpoint shareholders, including the sale of the Company.  I continue to be available to discuss these matters with the Board and can be reached at (212) 586-4333.

Sincerely,

                                                                                /s/ Jerome Lande
