LLDPE SLL118/21

LLDPE SLL118/21

LLDPE SLL118/21 is a linear low density polyethylene (LLDPE) butene copolymer resin developed under Braskem's "I'm green" portfolio[cite: 7]. Specially designed to provide outstanding processing performance, the films obtained with this grade exhibit good physical and optical properties, along with enhanced sealability[cite: 7]. Supporting environmental sustainability initiatives, it features a minimum biobased carbon content of 87%, determined in accordance with the ASTM D6866 standard[cite: 7].

Key Features

• Linear low density polyethylene butene copolymer[cite: 7].
• Sustainable formulation with a minimum of 87% biobased carbon content[cite: 7].
• Engineered to provide outstanding processing performance and enhanced sealability[cite: 7].
• Formulated with slip and antiblock additives for optimized film conversion[cite: 7].
• Excellent mechanical properties, including remarkable elongation at break and tear strength[cite: 7].
