                                    FORM 8-K
                                       OF
                              MOLL INDUSTRIES, INC.
                                       AND
                              ANCHOR HOLDINGS, INC.

ITEM 5.   OTHER EVENTS.

         Moll Industries, Inc., formerly known as Anchor Advanced Products, Inc.
(the "Company"), and Anchor Holdings, Inc. have announced that the Company has
closed the offer to purchase for cash and solicitation of consents (the "Offer")
made with respect to its outstanding $100 million principal amount of 11- 3/4%
Senior Notes due 2004 (the "Notes"). The Offer expired at 5:00 p.m., New York
City time, on Tuesday, August 8, 2000 (the "Expiration Date") and the settlement
in the amount of $42,500,000, plus accrued interest scheduled to occur on
Thursday, August 10, 2000 was extended by one day and made on Friday, August 11,
2000 (the "Settlement Date")

         As of 5:00 p.m. on the Expiration Date, the Company had received
tenders and consents with respect to $74,630,000 aggregate principal amount of
Notes. Because this amount constituted more than the Required Consents needed to
amend the Indenture for the Notes (the "Indenture"), the Company entered into a
Supplemental Indenture, with the trustee under the Indenture (the "Trustee"). A
copy of the Supplemental Indenture is attached hereto as Exhibit 4.1 and is
incorporated herein by reference. The Supplemental Indenture amended the
Indenture to, among other things, (i) permit the Company to enter into the
Credit Facilities (as defined below), (ii) grant a security interest in certain
of the Company's assets, which ranks junior to the security interest granted in
connection with the Credit Facilities, to the Trustee acting on behalf of the
holders of the Notes that remain outstanding after the Settlement Date, and
(iii) require the Company to offer to repurchase the remaining Notes with the
proceeds of certain asset sales.

         In connection with the Offer, on the Settlement Date the Company
entered into a revolving bank facility which provided for borrowings up to $50.0
million and a term bank facility in the amount of $35.0 million, each with Bank
of America, N.A. (the "Credit Facilities").

         On August 11, 2000, the Company issued a press release relating to the
completion of the Offer. A copy of the press release is attached hereto as
Exhibit 99.1 and is incorporated herein by reference.
