OPINION

Appellants Thomas Fox and Robert Wasserman, as trustee for Target Industries, Inc., and Lance Plastics, Inc., and Cross-Appellants Martin Goz, Sr., et al, appeal the District Court’s affirmance of the Bankruptcy Court’s order dismissing their claims and counterclaims. For the reasons discussed below, we will affirm.1

*2361. Introduction

Thomas Fox bought the assets of the consolidated bankruptcy estate of Target and Lance, New Jersey corporations in the business of distributing and manufacturing plastic bags. Fox, along with the Trustee of the bankruptcy estate, then commenced an adversary proceeding in the Bankruptcy Court against former Target personnel who had left to work for a competitor, TriCor Corporation. Tri-Cor was owned by a former Target Officer, Guy Zimmer-mann. Fox sought damages from these former employees and Zimmermann (collectively, the Tri-Cor defendants), alleging various business torts, including the misappropriation of Target’s customer lists, tor-tious interference with contractual relations, and breach of duty of loyalty.2 The defendants counterclaimed, alleging that Fox had attempted to scare former Target clients from doing business with Tri-Cor.3

After both parties moved for summary judgment, the Bankruptcy Judge dismissed three counts in the complaint, but otherwise denied the motions.4 Following an unsuccessful interlocutory appeal of this order, the case was remanded to the Bankruptcy Court, this time before another judge. This judge conducted a 14-day trial, at the end of which he dismissed every claim in the proceedings. The District Court affirmed the Bankruptcy Court order, adopting its reasoning and analysis.

On appeal to this Court, Fox contends that the Bankruptcy Court erroneously determined that (1) Target’s customer lists were neither proprietary information nor property of the estate, (2) the Tri-Cor defendants did not breach any duty of loyalty to Target, (3) Zimmermann did not breach any fiduciary duties to Target and was not liable for fraudulent conveyances under 11 U.S.C. §§ 544(b)and 548, and (4) the Tri-Cor defendants did not tortiously interfere with Target’s contractual relations. The Tri-Cor defendants, in turn, allege that the Bankruptcy Court erred in finding that there was insufficient evidence to support their counterclaims.

II. Discussion

A. Proprietary Information

As the Bankruptcy Court found, customer lists may be proprietary information under New Jersey law, depending on *237the nature of the business and the restrictions placed on employees. Lamorte Burns & Co. v. Walters, 167 N.J. 285, 770 A.2d 1158, 1166 (2001). Customer lists of service businesses receive special protection because the names and addresses of customers are not publicly available or ascertainable. AYR Composition, Inc. v. Rosenberg, 261 N.J.Super. 495, 619 A.2d 592, 597 (N.J.Super.Ct.App.Div. 1993). Customer lists of non-service businesses may also be proprietary information if the lists contain information that is not publicly available and the company protects such information with restrictive covenants, such as confidentiality agreements or covenants not to compete. Platinum Mgmt., Inc. v. Dahms, 285 N.J.Super. 274, 666 A.2d 1028, 1038 (N.J.Super. Ct. Law Div. 1995).

Here, Target was not in a service business; rather, it sold plastic bags. Information about the sale of plastic bags is publicly available, and Target did not seek to protect information concerning its customers through restrictive covenants in its employment contracts. Accordingly, we hold that Target’s customer lists were not proprietary information and, consequently, not assets of the bankruptcy estate.

B.Duty of Loyalty

Even though none of the employees had signed restrictive covenants or confidentiality agreements, they nonetheless owed a common law duty of loyalty to Target while employed there. See Lamorte, 770 A.2d at 1168. This duty required the Tri-Cor defendants, while employed at Target, to refrain from competing with Target or otherwise acting contrary to Target’s interest. See id.

The Bankruptcy Court found that the Trustee had already closed Target and terminated its employees by the time TriCor was formed and the Tri-Cor defendants began to solicit Target’s customers. While the Bankruptcy Court considered evidence that the Tri-Cor defendants had prepared for this transition prior to their termination, it concluded this evidence did not indicate that they were in any way disloyal to Target while employed there.

Similarly, even though Zimmer-mann was an officer of Target when it filed for bankruptcy, the Bankruptcy Court found that he had been displaced from his responsibilities when the Trustee was appointed. Therefore, at the time of his alleged misconduct, he was not an officer or an “insider” for purposes of fraudulent conveyance liability, under 11 U.S.C. § 548.

Fox has offered no compelling evidence to convince us that the Bankruptcy Court’s findings of fact were clearly erroneous. We, therefore, hold that the Tri-Cor defendants are not liable for breach of duty of loyalty and that Zimmermann is not liable for breach of fiduciary duties or for fraudulent conveyance.

C.Tortious Interference

Because the Tri-Cor defendants neither misappropriated Target’s assets nor breached any duties owed to Target, we agree with the Bankruptcy Court that it was not improper for the Tri-Cor defendants to contact Target’s customers. Accordingly, we find that the Tri-Cor defendants did not tortiously interfere with Target’s contractual relations. See Printing Mart-Morristown v. Sharp Elecs. Corp., 116 N.J. 739, 563 A.2d 31, 36 (1989) (holding that tortious interference with contractual relations requires a “luring away, by devious, improper and unrighteous means, of the customer of another”) (internal quotation marks omitted).

*238D. Unfair Business Practices

Finally, the Bankruptcy Court found that the Tri-Cor defendants failed to present sufficient evidence to support their counterclaims for unfair business practices. The Tri-Cor defendants contend that two letters from Fox to Tri-Cor customers support their counterclaims. These letters alerted Tri-Cor’s customers to this pending action and to the possibility that Tri-Cor could be enjoined from doing business with them. We agree with the Bankruptcy Court that nothing in these letters is actionable.

III. Conclusion

For the reasons discussed above, we will affirm the judgment of the District Court, dismissing the claims and counterclaims.
