Mechanical properties of active packaging incorporated with antimicrobial peptides.

Mechanical property	Measurement unit	Significance
Maximum load	N	Measurement of the maximum load on the film registered in the tensile strength test
Tensile strength	MPa	Measurement of the ability of the film to withstand a defined load when submitted to traction
Load at break	N	Measurement of the load registered on the film at break point when performing the tensile strength test
Tensile strength at break	MPa	Measurement of film resistance to a load at break
Elongation at break	%	Measurement of the maximum deformation of the film presented before its rupture
Elastic modulus (Young's modulus)	MPa	Measurement of the film stiffness
Penetration resistance	N	Measurement of the ability of a flexible sheet material to withstand elongation and/or puncture by a driven probe
