MEHR-7000F
TYPICAL APPLICATION |
||||
♦ Recommend film thickness at 10-25 micron |
♦ Shopping bag and T-shirt bag |
|
||
♦ High tensile strength with good dart impact strength |
♦ Garbage bag |
|
||
♦ Low gel content |
|
♦ Liner bag |
|
|
♦ Good moisture barrier |
|
♦ Enhanced ultra thin film |
|
|
♦ Food contact applicable |
|
♦ High stiffness |
|
|
♦ Good impact resistance and processability |
♦ Wide service Temperature range, UV resistance |
The actual extrusion condition depends on type of using machine, size and film thickness of product required.
Generally, melt temperature should be 190-210 oC with BUR = 3-5 times and frost line height (FLH) = 8-10 times of die
diameter.
♦Store in original container in tidy according to the manual of Handling and Storage from Mehr Petrochemical Company .
♦Product(s) should be stored in dry and dust free location at temperature below 50oC and protected from direct sunlight
and/or heat, well-ventilated area, away from incompatible materials and food and drink, as this may lead to quality deterioration, which results in odour generation and colour changes and can have negative effects on the physical properties of this product.
♦ Keep container tightly closed and sealed until ready for use. Containers that have been opened must be carefully resealed
and kept upright to prevent leakage. Do not store in unlabelled containers. Use appropriate containment to avoid environmental contamination
♦The storage area should be stable and not be slopped.
