Working with mLLDPE SLIP-AB
Is mLLDPE easy to machine?
Rarely machined; if needed use sharp positive-rake tools, high speed and low feed with air cooling — the material is soft, gummy and springs back, so hold generous tolerances.
Can mLLDPE be welded?
Excellent heat sealing, hot-plate, impulse and extrusion welding to other PE; low seal-initiation temperature is a key selling point; no solvent bonding and adhesives need corona/flame surface treatment.
Can mLLDPE be formed, bent or molded?
Mainly blown/cast film — narrow MWD gives high extruder pressure and melt-fracture risk, so use a PPA, wider die gaps and grooved-feed or high-torque screws; also rotomoulded (powder) and injection moulded at 190–235 °C with cold tooling.
What surface finishes work on mLLDPE?
Non-polar surface: corona or flame treat to 38–42 dyn/cm before printing, laminating or coating; no plating; pigmenting via masterbatch.

mLLDPE SLIP-AB — frequently asked
What is mLLDPE SLIP-AB used for?
mLLDPE SLIP-AB is typically used for high-performance stretch film, heavy-duty shipping sacks, multilayer food packaging film and agricultural film. In short: toughest LLDPE film resin; low seal-initiation temperature; narrow-MWD metallocene grade.
What is the yield strength of mLLDPE SLIP-AB?
mLLDPE SLIP-AB has a typical yield strength of 10 MPa (1.45 ksi) and a tensile strength of 32 MPa (4.64 ksi) — weaker than 91% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is mLLDPE SLIP-AB easy to machine?
Not especially — machinability is rated fair (40/100, worse than 82% of polymer grades). Rarely machined; if needed use sharp positive-rake tools, high speed and low feed with air cooling — the material is soft, gummy and springs back, so hold generous tolerances.
Can mLLDPE SLIP-AB be welded?
Yes — weldability is rated excellent (95/100). Excellent heat sealing, hot-plate, impulse and extrusion welding to other PE; low seal-initiation temperature is a key selling point; no solvent bonding and adhesives need corona/flame surface treatment.
What surface finishes work on mLLDPE SLIP-AB?
Non-polar surface: corona or flame treat to 38–42 dyn/cm before printing, laminating or coating; no plating; pigmenting via masterbatch.
Can mLLDPE SLIP-AB be formed, bent or molded?

What is the maximum service temperature of mLLDPE SLIP-AB?
mLLDPE SLIP-AB is rated for continuous use to about 75°C (167 °F), and briefly to 95°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between mLLDPE NAT-C6 and mLLDPE ROTO?
NAT-C6 is the default condition — standard high-clarity blown-film mLLDPE for stretch/collation and packaging film; best balance of price and toughness. ROTO: heat-stabilised, ground-powder mLLDPE for tanks and containers where impact at low temperature and ESCR matter. Yield strength is 10 MPa in NAT-C6 versus 17 MPa in ROTO.
