Oxidized polyethylene may safely be used as a component of food provided it meets certain requirements.
The oxidized polyethylene M 3400 is produced by a mild air oxidation process and also conforms to the requirements laid down in 21 CFR 177.1520 ( c ) item 2.3. It is therefore permitted for use either by itself or as a component of a protective coating for a broad range of fresh fruit ranging from Avocados to Walnuts.

21 CFR 175.125 Pressure - sensitive adhesives
Pressure - sensitive adhesives, which may be safely used as the food, contact surface of labels and / or tapes applied to food in accordance with prescribed conditions.
The homopolymer grades (including
micronized types) and oxidized polyethylene M 3400 conform to the specifications

21 CFR 175.300 Resinous and polymeric coatings
The coating is applied as a continuous
film or enamel over a metal substrate, or the coating is intended for repeated
food contact use and is applied to any suitable substrate as a continuous
film or enamel that serves as a functional barrier between the food and
the substrate.
The homopolymer grades (including
the micronized types) are permitted as components of the subject coatings
in amounts of up to 50% by weight
The coatings are subject to extraction
limits with a number of solvents, which simulate varying types of foods
and beverages. The tests prescribed in this regulation have been carried
out on pure (100%) MARCUS polyethylene coatings and the results confirm
that any coating containing them as a component would fall well within
the limitations set.

21 CFR 177.1200 Optional substances for cellophane
Cellophane may be safely used for food
packaging. Frequently cellophane, which is made from regenerated cellulose,
is modified with additives, which are approved for food contact use.
The homopolymers (including the
micronized grades) and the oxidized polyethylene M 3400 are permitted as
components of cellophane which is used for food packaging purposes. The
homopolymers may be used in an amount of up to 50% by weight. The M 3400
is permitted as it conforms to the specification set in 21 CFR 177.1620.
21 CFR 177.1210 Closures with sealing gaskets for food containers
Closure sealing gaskets and overall discs may be safely used on containers intended for use in producing, manufacturing, packing, processing, preparing, treating, and packaging transporting or holding food.

21 CFR 177.1520 Olefin polymers
This regulation is the covering one for polyolefins and compliance to which is required for other food contact regulations.
The homopolymers (including the micronized types) are permitted as components for food contact purposes and in an amount of up to 50% by weight. The homopolymers do conform to the requirements set in the section of this regulation ( (c ) item 2.3 ). This has previously been outlined under 21 CFR 175.125.
21 CFR 177.1620 Oxidized polyethylene
This regulation is the covering one for oxidised polyethylenes and compliance to which is required for food contact regulations.
The oxidized polyethylene M 3400 is permitted as it conforms to the identity specified (and as previously outlined under 21 CFR 175.105). The M3400 use is subject in some regulations to extraction limitations. These do not apply in the instances of 21 CFR 175.105, 175.125, 176.170 ( a ), 176.210 or 177.1200.
21 CFR 177.2600 Rubber articles intended for repeated use
Rubber articles (and prepared from natural and/or synthetic polymers) intended to come into contact by various means as previously stated under other regulations.
The homopolymers (including the micronized types) and the oxidized polyethylene M 3400 are permitted in an amount not to exceed that required to produce the intended technical effect and this is a maximum of not more than 2% upon the weight of the rubber product.
21 CFR 177.200 Textile and textile fibres
Textile fibres may be safely used for food contact purposes by various means as previously stated under other regulations. However, fibres are frequently subjected to a variety of treatments prior to use in order to impart desirable property improvements. This regulation governs what may be used and in an amount not to exceed that required to produce the intended effect.
The oxidized polyethylene M 3400 in its capacity as a product produced by an air blowing technique and as conforming to the parameters defined under 21 CFR 177.1620, is a permitted treatment for fibres coming into contact with foodstuffs.
21 CFR 178.3570 Lubricants with incidental food contact
Lubricants with incidental food contact and arising from various means as previously described may be safely used subject to certain restrictions. The incidental food contact arises as the lubricant is used on food processing equipment as a protective antirust film or, as a release agent or machine part lubricant.
The homopolymer grades (including the micronized types) and the oxidized polyethylene M 3400 are permitted providing that the amount does not exceed that required to achieve the intended effect and, that the amount which may be incorporated into the food does not exceed 10 parts per million.
21 CFR 178.3850 Reinforced wax for food packaging
Reinforced wax may safely be used as an article or component of an article intended for use in producing and manufacturing vinyl chloride polymers and the modifying polymers present in the polymer mixture used in the manufacture of the food contact article.
The homopolymer grades (including the micronized types) and the oxidized polyethylene M 3400 are permitted for use provided the amount used is no more than necessary to achieve the intended effect and, that the extraction limitations for the packaging of cheese and cheese products are observed.
21 CFR 179.45 Packaging for use during the irradiation of pre-packaged foods
A number of packaging materials are identified in this regulation which may be safely subjected to irradiation incidental to the radiation treatment and processing of pre-packaged food. This is also subject to the requirement that no induced radioactivity is detectable in the packaging material itself.
The homopolymer grades (including the micronized types) and the oxidized polyethylene M 3400 are permitted.
