Plastics films represent the largest volume of plastic consumption. This end use area cover flexible packaging substrates, industrial packaging, agricultural films and protection films.

A high number of specialised tests exist for films and Norner is a specialist in this field and our lab are well equiped for this purpose.

Norner offer the following tests within film and flexible packaging

• Film behaviour under impact, compression and tension
• Dart drop
• Elmendorf tear resistance
• Trouser tear test
• Hot tack and sealing performance
• Heat shrinkage
• Shrink force analysis (hot and cold phase)
• Creep, deformation under stress
• Tensile properties and stiffness
• Puncture resistance
• Film elasticity and holding force
• IFW, instrument failing weight
• COF, coefficient of friction
• Gel counting
