DUS 1891:2019, Standard Specification for Plastic Films Made from Low-Density Polyethylene and Linear Low-Density Polyethylene for General Use and Packaging Applications, First Edition (18 page(s), in English)
This Draft Uganda Standard covers unpigmented, unsupported, low-density polyethylene and linear low-density polyethylene films (hereafter referred to as film or films) with densities ranging from 0.910 g/cm3 - 0.925 g/cm3.
Note 1. The density of a film will not necessarily be equal to the density of a moulded plaque from the same resin.
Note 2. Blends of ethylene/vinyl acetate (EVA) with low-density polyethylene may have densities up to 0.929 g/cm3.
This Draft Uganda Standards is applicable to homopolymer polyethylene, but is not restricted to it. It is applicable to films made from polyethylene copolymers, and also applicable to films made from blends of homopolymers and copolymers, including ethylene/vinyl acetate copolymers. The thickness of the films covered by this Draft Uganda Standard is from 30.0μm to 101.6μm, inclusive. The maximum width of the sheet or lay flat is 3.30m. The Draft Standard does not cover oriented heat-shrinkable films.
The Draft Standard allows for the use of recycled polyethylene film or resin as feedstock, in whole or in part, as long as all of the requirements of this specification are met and as long as any specific requirements as governed by the producer and end user are also met. It defines the levels of the various physical properties from which specifications for specific films may be described.
The Draft Standard covers dimensional tolerances, classifications, intrinsic quality requirements, and test methods. The dimensional tolerances include thickness, width, and length or yield. Classification defines types, classes, surfaces, and finishes. The intrinsic quality requirements include density, workmanship, tensile strength, heat sealability, and odour, as well as the classification properties for impact strength, coefficient of friction, optical properties, and surface treatment. A sampling method is included. The Draft Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
