Item 1.  Financial Statements


                             INTRODUCTORY COMMENTS
                             ---------------------

     The Consolidated Financial Statements included herein have been prepared by
Management, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission.  Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted
pursuant to such rules and regulations, although Management believes that the
disclosures are adequate to enable a reasonable understanding of the information
presented.  It is recommended that these Consolidated Financial Statements be
read in conjunction with the financial statements and the notes thereto included
in the Company's  Annual Report  filed March 30, 1999 on Form 10-K for the year
ended December 31, 1998.

     Except for historical information contained herein, the matters set forth
in this report or in oral statements made by officers of the Company are
forward-looking statements that involve certain risks and uncertainties that
could cause actual results to differ materially from those in the forward-
looking statements.  The Company's expectations respecting future revenues and
profits assume, among other things, reasonable continued growth in the general
economy which affects demand for the Company's products, reasonable stability in
raw material pricing, changes in which affect customer purchasing decisions as
well as the Company's revenues and margins.  Investors are advised to consider
these and other risks and uncertainties that may be discussed in documents filed
by the Company with the Securities and Exchange Commission.

                                MARCH 31, 1999

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - FINANCIAL STATEMENT PRESENTATION

     The accompanying financial statements include the accounts of two former
wholly owned subsidiaries of Sealright Co., Inc. (Sealright) and the accounts of
a portion of Sealright and another subsidiary.  The resulting entity operates
the San Leandro, California, Raleigh, North Carolina, and Akron, Ohio,
facilities and is collectively referred to as JPS Packaging Company (the
Company).

     On March 24, 1998, the Company was reorganized and incorporated as a
Delaware corporation (the reorganization).  The Company is authorized to issue
15,000,000 shares of common stock, $0.01 par value, and 1,000,000 shares of
preferred stock, $0.01 par value.  The Company has one wholly owned subsidiary,
incorporated in North Carolina.


     The information included in these condensed consolidated financial
statements reflects all adjustments (consisting only of normal recurring
accruals) which, in the opinion of management, are necessary for a fair
statement of the results for the interim periods presented.

NOTE 2 - ACCOUNTING PRINCIPLES AND POLICIES

     The accompanying financial statements have been prepared consistent with
the accounting principles and policies described more fully in Note 1 of the
Company's Annual Report for the year ended December 31, 1998. Consistent with
such Annual Report, financial information for 1998 has been restated to present
the Raleigh, North Carolina machine manufacturing business as a discontinued
operation.

     Net income (loss) per share for period ended March 31, 1998 is based on the
number of common shares issued in connection with the reorganization.

     The Company adopted Financial Accounting Standards Board (FASB) Statement
No. 130, "Reporting Comprehensive Income," in the first quarter of 1998, however
the Company had no items that would be considered components of other
comprehensive income.

NOTE 3 - INVENTORIES

     Inventories are stated at lower of cost or market. Finished products, work
in process and raw material inventories are carried at last-in, first-out (LIFO)
cost. Certain machine parts and supplies inventories are carried at first-in,
first-out (FIFO) cost. Inventories include the cost of material, labor and
factory overhead required in the production of the Company's products.
Inventories at March 31, 1999 and December 31, 1998 were:

</TABLE>

     Because the inventory determination under the LIFO method can only be made
at the end of each fiscal year based on the inventory levels and costs at that
time, interim LIFO determinations, including those at March 31, 1999, must
necessarily be based on management's estimate of expected year-end inventory
levels and costs. Since estimates of future inventory levels and prices are
subject to many factors beyond the control of management, interim financial
results are subject to final year-end LIFO inventory amounts. Accordingly,
inventory components reported for the period ended March 31, 1999, are estimates
based on management's knowledge of the Company's production cycle, the costs
associated with this cycle and the sales and purchasing volume of the Company.

NOTE 4 - INCOME TAXES

     The operations of the Company were historically included in the
consolidated Federal income tax returns of Sealright. The policy of Sealright
was to allocate consolidated Federal income tax expense to members of the
affiliated group, including the Company, on a stand-alone basis. Subsequent to
the spin off the Company files separate tax returns.

ITEM 2.


              MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS
                            AND FINANCIAL CONDITION


Results of Operations

Three months ended March 31, 1999 and March 31, 1998

     Net sales for the first quarter of 1999 were $20.7 million versus $20.0
million in the first quarter of 1998, an increase of approximately $.7 million,
or 3.5%. Sales in the San Leandro facility were up approximately $1.5 million or
19% from first quarter 1998. The increase is attributable to both the addition
of new customers and an increase in volume with existing customers. The increase
in San Leandro was offset by a decline in sales in the Akron facility of 3%.
This decrease was due primarily to the loss of three customers.

     Consolidated gross margin was $2.4 million for the first quarter of 1999 as
compared to $1.6 million during the first quarter of 1998. The resulting gross
margin was 11.7% of sales in 1999, an increase from 7.9% in 1998. Gross margin
increased primarily due to material cost savings at both plants. Increased sales
volume in the San Leandro facility combined with increased efficiency at both
plants have also had a positive impact.

     Selling, general and administrative expenses (SG&A) were $2.4 million for
the first quarter of 1999 as compared to $3.1 million during the first quarter
of 1998. The major decrease in SG&A expense is attributable to the reduction in
allocated corporate expense from Sealright. As a percentage of sales SG&A
decreased from 15.6% in 1998 to 11.6% in 1999. Higher sales volume and reduced
spending accounted for the decrease as a percentage of sales.

Liquidity and Capital Resources


  Net cash used by continuing operations was $3.0 million for the three months
ended March 31, 1999 compared to cash provided of $697 thousand for the same
time period in 1998. Cash was primarily used in the first quarter of 1999 to
purchase raw materials and to carry receivables related to the increase in
sales. The increase in sales in San Leandro and the seasonal increase in the
soft drink industry created a need for higher inventory levels than at December
31, 1998.

  For the first three months of 1999, the Company had capital expenditures of
$899 thousand for improvements to production related equipment and the purchase
of computer hardware and software.

  The Company has historically relied on internally generated cash from
operations as well as funding from Sealright. As a result of the separation from
Sealright, the Company established a $15,000,000 credit facility with a bank, of
which none was borrowed at March 31, 1999. The facility is secured by certain
assets of the Company, principally inventory, receivables and property, plant,
and equipment. The borrowings under the facility are limited to a percentage of
accounts receivable and inventory. At March 31, 1999, the Company had unused
borrowing capacity of $14.8 million. The initial interest rate is the prime rate
of Harris Trust and Savings Bank or LIBOR plus 275 basis points. Management
believes that cash generated by operations and funds available under the
revolving credit facility will be sufficient to meet the Company's expected
operating needs, planned capital expenditures and debt service requirements.

  Pursuant to its debt agreement, the Company must comply with various financial
covenants. As of March 31, 1999, the Company was in compliance with these
financial covenants.


Discontinued Operation


  During the third quarter of 1998 the Company decided to exit its Styrotech
machine manufacturing business.  The Company has been seeking a buyer and at the
end of March 1999 had an interested buyer who had signed a letter of intent.


Year 2000 Compliance


    The Company's information systems are not currently year 2000 compliant.
Management estimates that it will cost approximately $350,000 to modify the
information systems and become year 2000 compliant.  The Company has expended
approximately

                                       11
<PAGE>
 
$320,000 of which $95,000 was charged to operations in the first quarter of
1999. The Company is currently implementing and testing the necessary changes,
and management believes the information systems should be year 2000 compliant by
August 31, 1999. However, there can be no assurance that the information systems
will be compliant prior to the beginning of year 2000 and could therefore have
an adverse effect on the future financial results of the Company. The Company
does not have a formal contingency plan in place should the information systems
not be compliant prior to the beginning of year 2000, and will develop a
contingency plan by September 30, 1999.

    The Company is currently in the process of determining whether its major
suppliers are year 2000 compliant and will have a plan for those who are not
compliant by September 30, 1999. The Company doesn't anticipate any problems in
securing the necessary inventory for production as there are multiple vendors
which can supply the necessary products.

New Accounting Pronouncements

    In June, 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. The statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives) and for hedging activities. The statement requires that an entity
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. The Company will
adopt the provisions of SFAS No. 133 effective July 1, 1999. The Company does
not expect implementation to have any effect on its financial statements.
