TASNEE LD 1925AS POLYETHYLENE

DESCRIPTION
TASNEE LD 1925AS is a Low Density Polyethylene with a Melt Flow Rate of 1.9 g/10min (190°C/2.16kg).

TASNEE LD 1925AS is mainly recommended for shrink film applications. It contains slip agent and anti-
blocking additives and has a suitable molecular structure to produce film with excellent mechanical properties.

TASNEE LD 1925AS can be easily processed on all types of extruders designed for polyethylene. The melt
temperature is suggested to be in the range of 160 – 190°C. Excellent properties of the film are achieved with a
blow - up ratio of 2:1 and recommended film thickness range from 25 to 60 μm.

TYPICAL APPLICATIONS:
Bags & Pouches, Shrink Film, Food Packaging, Surface Protection.

PRODUCT CHARATERISTICS
Features: Anti-Blocking and Slip Additives, Good Optical Properties, Good Processability, Low Friction.

Safety

The material is manufactured to the highest standards but, special requirements apply to certain applications,
such as food contact end-use. For specific information on regulatory compliance contact your local
representative Workers should be protected from the possibility of skin or eye contact with molten polymer.
Safety glasses are suggested as minimum precaution to prevent mechanical or thermal injury to the eyes.
Molten polymer may be degraded if it is exposed to air during any of the processing and off-line operations.
The products of degradation have an unpleasant odor. In higher concentrations they may cause irritation of the
mucus membranes. Fabrication areas should be ventilated to carry away fumes or vapors. Legislation on the
control of emissions and pollution prevention must be observed. If the principles of sound manufacturing
practice are adhered to and the place of work is well ventilated, no health hazards are involved in processing
the material.

The material will burn when supplied with excess heat and oxygen. It should be handled and stored away from
contact with direct flames and/or ignition sources. In burning the material generates considerable heat and may
release a dense black smoke. Minor fires can be extinguished by water; developed fires should be extinguished
by heavy foams forming an aqueous or polymeric film. For further information about safety in handling and
processing please refer to the Material Safety Data Sheet (MSDS).

Storage

The material is packed in 25 kg bags or in bulk containers protecting it from contamination. Storage times of
natural materials longer than 3 months may have a negative influence on the quality of the final product. It is
generally recommended to convert all materials latest within 3 months of production. The material is subjected
to degradation by ultra-violet radiation or by high storage temperatures. Therefore the material must be
protected from direct sunlight, temperatures above 40°C and high atmospheric humidity during storage. Further
unfavorable storage conditions are large fluctuations in ambient temperature and high atmospheric humidity.
These conditions may lead to moisture condensing inside the packaging. Under these circumstances, it is
recommended to dry the material before use. Unfavorable storage conditions may also intensify the material's
slight characteristic odor.
