(International Paper-Temple Inland item update with further analyst commentary.)

NEW YORK ( TheStreet) -- International Paper's ( IP - Get Report) move to acquire Temple-Inland ( TIN) is yet another example of how low interest rates are motivating deals among manufacturing companies on the hunt for growth and increased market share.

Credit-worthy corporations are racing to take advantage of inexpensive loans before rates eventually rise, analysts say. "To borrow money now is cheap," said Thomas Mullarkey, a stock analyst who covers packaging makers and other manufacturing companies for Morningstar ( MORN) in Chicago. "IP can probably get 5% as an interest rate on debt for its Temple acquisition, while their cash is getting nothing. So almost any acquisition is going to be accretive to earnings," assuming that the company's base profit for 2012 remains flat.

UBS ( UBS) has agreed to provide debt financing for the deal, International Paper said when it disclosed its offer Monday, though it didn't specify terms.

The number of big transactions in corporate America has picked up in 2011. Since the beginning of the year, 29 U.S. public-market deals have been struck worth more than $2 billion, according to Dealogic. (The total value of those transaction: $169.3 billion The biggest was Duke Energy's ( DUK) $13.6 billion take-out of Progress Energy ( PGN).) That compares with 17 transactions worth $2 billion or more in the first half of 2010 (there were 46 such deals in all of last year).

The low interest-rate environment has become so M&A-friendly that some companies have made deals that the market views as dubious. Last week, Sealed Air ( SEE - Get Report), which produces the Bubble Wrap packaging that few human beings can resist popping, made a $2.9 billion bid to acquire the privately held Diversey Holdings, which makes industrial cleaners.

Sealed Air's largest shareholder, the fund manager Davis Selected Advisors, has publicly opposed the deal, arguing that industrial cleaning producers were too far afield from Sealed Air's core business.

Packaging in general has been a hot segment for deals (and controversy) of late. Rock-Tenn ( RKT) subsumed Smurfit-Stone in a $3.5 billion deal announced in January. And in April, the aluminum-can maker Silgan Holdings ( SLGN - Get Report) agreed to acquire Graham Packaging ( GRM) for $1.3 billion -- another deal that has drawn criticism, with a slew of class-action law firms attempting to gain traction with potential suits, claiming Graham's board undersold the company.

International Paper has some wooing to do after Temple-Inland roundly rejected its offer as "obscenely" low, in the words of Morningstar's Mullarkey.

On its web site, the Austin, Texas-based maker of corrugated cardboard boxes and wood-based construction materials uploaded a detailed presentation meant to make the case that IP has undervalued Temple. The company also instituted a poison-pill strategy in hopes of thwarting an IP hostile takeover, declaring a special dividend meant to dilute any move by the paper giant to acquire Temple's stock.

Temple-Inland didn't immediately respond to an email seeking comment. The company's phone lines, meanwhile, were evidently inundated with calls Tuesday morning; all circuits were busy.

After the closing bell Monday, International Paper went public with its offer of $30.60 per share, or $3.38 billion, after a round of private talks last month that fell through.

In its presentation, Temple-Inland argues that its profit margins are wider than what IP has given it credit for in its "opportunistic" bid.

Temple also raised the prospect of antitrust hurdles that IP would face. A successful acquisition would bring the Memphis, Tenn.-based IP's market share up to nearly 40% of the packaging market. Still, notes Morningstar analyst Mullarkey, the highly consolidated aluminum-can market saw Ball Corp. ( BLL) acquire several plants from Anheuser-Busch Inbev ( BUD) two years ago without regulatory problems. The deal lifted Ball's share to 40% of the can market, Mullarkey said.

Shares of Temple-Inland were trading below the offer price, at $29.54, up 40% from the previous close.

IP shares, meanwhile, were gaining almost 0.6% to $29.82.

The deal news drove share prices higher among several other paper-and-packaging companies as investors bet on further consolidation and increasing asset values. Packaging Corp. of America ( PKG - Get Report) shares were rising 6.5%, while MeadWestvaco ( MWV) was gaining 4.4%.
