Additional informations:

The product compounds are listed in and are in conformity with Directive 2002/72/EC and Government Resolution HG 879/2005.

SLIP AGENT: Type Erucamide, is FDA approved. Our supplier has registered the product and guarantees this.

    “Erucamide (erucyl amide, amide of erucic acid) is listed in 21 CFR (FDA) in section:
    • § 175.105 (adhesives).
    • § 175.320 (resinous and polymeric coatings for polyolefin films) (b)(3)(iii) as amides (unsubstituted) of fatty acids from vegetable or animal oils“ for the use as an adjuvant.
    • § 176.180 (components of paper and paperboard in contact with dry food.
    • § 177.1200 (cellophane).
    • § 177.1210 (closures with sealing gaskets for food containers), to be used in amounts of up to 5 % of the gasket composition.
    • § 177.1350 (ethylene-vinyl acetate copolymers)
    • § 177.1400 (hydroxyethyl cellulose film, water-insoluble), (b)(4) substances identified in and used in compliance with § 177.1200(c).
    • § 177.1520 (olefin polymers), (b) referring to an adjuvant permitted by applicable regulations in §§ 170 through 189.
    • § 178.3860 (release agents).
    • § 179.45 (packaging materials for use during irradiation of pre-packaged foods) (d) (2) (i) as an adjuvant, in levels not to exceed 1% w/w of the polymer.

In general, these CFR sections should always be consulted for the complete context before any conclusion is made as to the allowed regulated use.”

    Quality control: Control is performed on lots.
  • During test operation, the product must comply all the parameters depicted in this standard specification.
  • In case of litigation, the control of the quality will be done in the presence of the client representative, using the samples kept for those cases. The samples will be taken in accordance with the sampling procedure.

    Low-density polyethylene is an inert commercial polymer and under normal handling induces no hazard. Product storage must be in accordance with MSDS procedure. The working people should avoid skin or eyes contact with molten polymer. As a minimal precaution to prevent eyes injury, safety glasses are indicated.
    Fabrication areas should be well ventilated. Workplace environments should be kept clean and free of dust.

    Fire hazard:
    Low-density polyethylene is a combustible substance, but under normal storage conditions there is no ignition hazard. In contact with flame it becomes soft, flows, ignites and burns with a light flame until exhausting. Therefore it has to be handled and stored avoiding contacts with open flames or other ignition sources. While burning, it releases high heat and a dense black smoke. In closed areas, fire fighters must use self-contained breathing apparatus.

    Low-density polyethylene is a recyclable material. It is recommended to recycle production rejects and wastes instead of disposal.

    Disposal of any wastes should respect all national and local valid regulations. The below information are related to Low density polyethylene homopolymer. The influence of the additives, fillers or other materials added by buyers must be taken into consideration using the related documentation. Low-density polyethylene homopolymer can be disposed by burying or by controlled incineration, respecting valid regulations regarding gaseous emission or solid particles discharges. Due to the high level of heat enduced, incineration has to be done only in dedicated units. In case of interring: low density polyethylene is inert, does not degrade quickly, form a strong and permanent soil base and does not release gases or other compounds known to pollute water resources.
