DESCRIPTION

POLYOLEFIN

The General Services Administration has authorized the use of this commercial item description by all Federal agencies.

1. SCOPE AND CLASSIFICATION

1.1. Scone. This document covers requirements for polyolefin film.

Polyolefin film covered by this document is intended for use in general purpose packaging applications where a high degree of water resistance, moderate moisture vapor resistance, and dust “protection are desired. The item is not intended for use in special packaging applications where special grease or oil resistance properties may be required. The class 1 film is intended to be used in building material shrouds and similar non-food applications. The class 2 film is intended to be used in food contact and wrapping applications.

1.2. Classification. For the purpose of this document, the

polyolefin film shall be classified as follows:

T~e V - Type VI -

Class 1 - Class 2 - Class 3 - Class 4 -

Grade A - Grade B - Grade C -

Finish 1 - Finish 2 -

Normal strength polyethylene High strength polyethylene Polypropylene Heat shrinkable polyethylene Heat shrinkable weather resistant polyethylene High density polyethylene

For non-food application For use in contact with food Biaxially oriented preferentially oriented

Low slip Medium slip High slip

Untreated Treated

2. SALIENT CHARACTERISTICS

2.1. Construction.

2.1.1. Tvoes I & II. Type I material shall be flexible unsupported normal strength polyethylene fil,m, meeting the physical requirements specified in Table I herein. Type II material shall be flexible unsupported high strength polyethylene film, meeting the physical requirements specified in Table I herein. Unless otherwise specified, Type I and II materials shall be made of Low Density Polyethylene (LDPE) , Linear Low Density Polyethylene [LLDPE), Medium Density Polyethylene (MDPE) or Linear Medium Density Polyethylene (LMDPE) .

2.1.2. Tvoe III. Type III material shall be flexible unsupported polypropylene film, meeting “the physical requirements specified in Table I herein.

2.1.3. Tvoes IV & V. Type IV material shall be flexible, unsupported, heat shrinkable polyethylene film. Type V material shall be flexible, unsupported, heat shrinkable, weather resistant polyethylene film.

Type V material shall not have more than an appreciable change in color* after exposure to accelerated weathering, when tested in accordance with Fed-Std-191, Method 5804 (carbon arc) with 200 hrs exposure with filters, or any other equivalent commercial method.

* Note 1: Appreciable change in color means a change which is immediately noticeable in comparing the test specimen with the original unexposed material. If closer inspection or change of light is required to make a slight change in color, the change is not considered appreciable.

2.1.4. me VI. The material shall be flexible, unsupported, high density polyethylene film, meeting the physical requirements specified in Table I herein.

2.2. Form The film shall be furnished in the”form of flat cut sheets—.

or in rolls, as specified. Material in roll form shall be either single thickness or lay flat tubing, as specified.

2.3. Dimensions.

2.3.1. Thickness. Unless otherwise specified, the thickness of the film is not a requirement and shall be at the option of the supplier.

For the purpose of this document, the nominal thickness shall be cited for identification only. The material shall meet or exceed all the physical requirements specified in Table I for the appropriate nominal thickness.

CFR Paragraph 177.1520.

2.6. Color. Unless otherwise specified, the film shall be of natural color (colorless) and transparent.

2.7. Workmanship. The workmanship shall be evaluated on the basis of the intended application of the material. The material shall be uniform in color, texture, finish, and other physical properties and shall be free from cuts, cracks, holes, dirt, gels, or other defects which may impair its utility or appearance.

I 2.8. Phvsical Reuu irements. The finished sheet or strip shall meet the physical requirements specified in Table I.
