Ladies and Gentlemen:

We have acted as special Louisiana counsel to Southern Plastics Inc., a Louisiana corporation (“Company”), in connection with the documents set forth on Schedule A attached hereto (the “Indenture”). In such capacity, we have reviewed the Indenture.

We have also reviewed the following corporate documents of the Company:

(a) Articles of Incorporation of the Company dated April 5, 1966; as amended by Unanimous Consent Agreement of Directors and Stockholders to Amend Corporate Charter dated March 2, 1970; as further amended by Articles of Amendment to the Articles of Incorporation of Southern Plastics, Inc. dated May 20, 1976; as further amended by Articles of Amendment to the Articles of Incorporation of Southern Plastics, Inc. dated October 15, 1992; and as further amended by Articles of Amendment to the Articles of Incorporation of Southern Plastics, Inc. dated September 15, 2009 (collectively, the “Articles”); and

(b) By-laws of Southern Plastics, Inc. (the “Bylaws”; collectively, the Articles and the Bylaws are the “Constituent Documents”); and

(c) various certificates by the Company’s Secretary or Assistant Secretary with respect to the Company’s corporate documents, resolutions and incumbency of officers (the “Secretary’s Certificates”).

In rendering our opinion we have also examined such certificates of public officials, corporate documents and records and other certificates and instruments as we have deemed necessary for the purposes of the opinion herein expressed, including without limitation, a Certificate of Good Standing for the Company issued by the Louisiana Secretary of State dated December 19, 2012 (the “Good Standing Certificate”). As to questions of factual matters, we have relied upon certificates and written statements of officers of the Company, but we have no knowledge that any of such statements are inaccurate or incomplete.

The following terms shall have the following meanings when used herein.

• “laws” means laws, statutes, rules, regulations, ordinances, codes, judgments, cases, decrees or other similar authorities.

• “State” shall mean the State of Louisiana.

In rendering this Opinion, we have assumed:

a. the authenticity of all documents submitted to us as originals, the legal capacity of any individual signing any documents, the genuineness of all signatures on all documents and certificates referred to herein or relied upon by us, and the conformity to originals of all documents sent to us as copies;

b. that all parties to the Indenture other than the Company are each validly organized under the laws of the state of its organization and had the power and authority to execute and deliver the Indenture to which it is a party and to perform its obligations thereunder;

c. the execution, delivery and performance of the Indenture and all other documents executed in connection therewith, as to each party thereto other than the Company, (i) have been duly authorized by all necessary corporate action; and (ii) do not contravene any provision of its organizational documents, as applicable. The execution, delivery and performance of the Indenture and all other documents executed in connection therewith, as to each party thereto, do not contravene or constitute a breach of or default under any applicable provision of the laws or public policies of any jurisdiction other than the State, or any applicable regulation thereunder, or under any agreement or other instrument binding upon it, or under any judgment, injunction, judicial order or judicial decree;

d. the execution, delivery and performance of the Indenture and all other documents executed in connection therewith, as to each party thereto, do not require any authorization, approval or consent of, or filings or registrations with, any governmental or regulatory authority or agency other than the State or any third party, and as to each party thereto other than the Company, do not require any authorization, approval or consent of, or filings or registrations with, any governmental or regulatory authority or agent of the State, except for authorizations, consents, approvals that have already been obtained or filings that have already been made and that remain in effect;

e. that there are no written or oral terms and conditions agreed to by and between the parties to the Indenture that vary or could be deemed to vary the truth, completeness, correctness, validity, or effect of the Indenture in any material manner; and

f. that the Company’s business is and has always been limited to the manufacture of consumer goods for wholesale and retail sale.

We do not represent the Company on a general or regular basis and, accordingly, have no detailed information concerning its business or operations. Therefore, nothing contained herein should be construed as an opinion regarding the Company or its operations satisfying or otherwise complying with any local laws or ordinances or laws or ordinances of general application pertaining to the particular business and operations of the Company.

Further, with respect to certain factual matters, we have relied exclusively on the Secretary’s Certificates and have not conducted any independent investigation or verification of the matters set forth therein. We are not responsible in any fashion for any factual errors contained in the Secretary’s Certificates.

Based on the foregoing and upon such investigation as we have deemed necessary, and subject to the qualifications and exceptions herein contained, we are of the opinion that, under applicable law on the date of this Opinion:

1. The Company is a corporation, duly organized, validly existing and in good standing under the laws of the State and is capable of suing and being sued in its corporate name.

2. The Company has (i) the corporate power to enter into and perform its obligations under the Indenture, and (ii) duly authorized the Indenture.

3. At the time the Indenture was executed by the Company, the execution, delivery and performance of the Indenture by the Company did not violate (i) any term or provision of the Constituent Documents, or (ii) any law, rule, regulation or order of the State applicable to the Company.

4. At the time the Indenture was executed by the Company, it was not necessary in order to ensure (a) that the Indenture constitutes the legal, valid and enforceable obligations of the Company, to the extent the Indenture was enforceable, or (b) the admissibility of the Indenture in the State that (i) the consent, license, approval or authorization of any State court or governmental body be obtained; or (iii) the Indenture or any other document be filed, recorded or registered, or that any other similar action be taken (except as otherwise set forth herein).

In addition to the assumptions set forth above, the opinions set forth above are also subject to the following qualifications:

a. We express no opinion with respect to the enforceability of the Indenture.

We understand that you will rely as to matters of Louisiana law, as applicable, upon this opinion in connection with the matters set forth herein. In addition, we understand that Debevoise & Plimpton LLP (“Debevoise”) will rely as to matters of Louisiana law, as applicable, upon this opinion in connection with an opinion to be rendered by it relating to the Company. In connection with the foregoing, we hereby consent to your and Debevoise’s relying as to matters of Louisiana law, as applicable, upon this opinion.

We consent to the filing of this opinion as an exhibit to Amendment No. 1 of the Registration Statement and to the reference to our firm under the heading “Validity of the Securities” in the prospectus contained therein. In giving such consent, we do not hereby concede that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the U.S. Securities and Exchange Commission thereunder.

We are admitted to practice only in the State of Louisiana, and the foregoing opinions are limited to the laws of said State. We are not opining as to any securities laws, blue-sky law, zoning, land use or environmental laws. We have not been requested to review, and have not undertaken to review, federal or state banking laws or regulations in order to determine if any lender’s entering of the transaction is in compliance with such laws or regulations. We undertake no responsibility to advise of any law that becomes effective after the date of the effectiveness of the Registration Statement or changes in the facts after the date of the effectiveness of the Registration Statement that would alter the scope or substance of the opinions expressed herein. This Opinion expresses our legal opinion as to the foregoing matters based on our professional judgment at this time; it is not, however, to be construed as a guaranty
