Environment-friendly thermoplastic elastomer composition for stretch films

The invention discloses an environment-friendly thermoplastic elastomer composition for stretch films. The composition is prepared by adopting the following components in parts by weight: 100 parts of styrene elastomer, 50-100 parts of rubber oil, 5-15 parts of polystyrene resin, 0-5 parts of a compatibilizer, 0-4 parts of petroleum resin, 1-2 parts of silicon resin, 0-6 parts of inorganic filler and 0.2-0.5 parts of other additives. The stretch film prepared by adopting the thermoplastic elastomer composition disclosed by the invention has the advantages of good rebound elasticity, good autohension and excellent mechanical property; meanwhile, the composition has the advantages of high processing efficiency, health, safety and environmental protection and can replace polyethylene films to be applied to card boards and other packaging fields.
