Typical Values: not to be construed as specifications limits.
• Properties are based on 25 μm blown film produced at a melt temperature of 160°C and
3 BUR using 100% LTM 2047/37.
Application
LFI2047A is recommended for blown film extrusion. This product is very suitable for high
clarity laundry bags, textile wrapping films and zip lock bags. This grade enables high speed
converting without sticking.
General information
LFI2047A has been manufactured using SABTEC licensed technology.
Processing Conditions:
Extruder temperature profile: 145-160°C
Frost line height: 5-7 times die diameter.
Blow Up Ratio: 2-3
Recommended film thickness: 25 to 50 μm.
Please note that, these processing conditions are recommended by producer only for 100%
LFI2047A resin (not in the case of blending with any other compatible material), but because
of the many particular factors which are outside our knowledge and control, and may affect
the use of product, no warranty is given.

• Phthalates, Directive 2005/84/EC
Pharmaceutical Application
The above mentioned grade meets the requirements of the European pharmacopeia version 6
section 3.1.5 for pharmaceutical application.
Conveying
Conveying equipment should be designed prevent accumulation of fines and dust particles can,
under certain conditions, pose an explosion hazard. We recommend that the conveying system
used:
1. be equipped with adequate filters
2. is operated and maintained in such a manner to ensure no leaks develop
3. that adequate grounding exists at all times
We further recommended that good housekeeping will practiced throughout the facility
Storage
As ultraviolet light may cause a change in the material, all resins should be protected from
direct sunlight and/or heat during storage. The storage location should also be dry, dust Free
and the ambient temperature should not exceed 50 0C. It is also advisable to process
polyethylene resins (in pelletized or powder from) within 6 months after delivery, this because
also excessive aging of polyethylene can lead to a deterioration in quality.
Handling
Minimal protection to prevent possible mechanical or thermal injury to the eyes. Fabrication
areas should be ventilated to carry away fumes or vapors.
Combustibility
Polyethylene resins will burn when supplied adequate heat and oxygen. They should be
handled and stored away from contact with direct flames and/or other ignition sources .in
burning; polyethylene resins contribute high heat and may generate a dense black smoke. Fires
can be extinguished by conventional means with water and mist preferred. In enclosed areas,
fire fighters should be provided with self contained breathing apparatus.
