The puncture resistance is a property found in flexible packaging materials. In several applications, the packaging coat is more prone to damage by penetration that leads to loss of barrier properties, package integrity and product attractiveness. To analyse the mechanism of puncture in flexible laminates, this property plays an important role. Although various methods have been formulated to describe the puncture failure of several types of systems like thick laminates or reinforced composite structures, these methods are of limited use for flexible packaging materials.
Puncture strength tests are used to identify the puncture or rupture characteristics of a material. A compressive test where the material is compressed by a probe or other type of device till the material breaks or till an elongation limit is reached. Puncture testing determines the strength of a material like rubber, film etc. It is used in the food processing industry to identify the texture of ripeness of a product. The test is also applied in the medical field to identify the sharpness of a syringe or blade to measure the resistance and softness of synthetic skin.
