In the field of preservation, there is a type of preservation film attached to the surface of fruits. This is a transparent, lightweight, breathable, and barrier protective film formed on the fruit skin through specific processes such as spraying, soaking, and application. Its core function is to simulate some of the functions of the natural skin of fruits, delay post harvest aging, and reduce losses. It belongs to an important branch of food grade preservation technology and is often referred to as Fruit preservation coating "or" biomimetic preservation film ".

Baosheng texture analyzer（TA. XTC-20As a professional device capable of accurately quantifying the mechanical and sensory properties of materials, it simulates the process of force application (such as stretching and compression) to obtainFracture strength, elongation at break, tensile strengthProvide standardized solutions for evaluating the texture and properties of fruit preservation films based on objective data.

Tensile strength（Tensile Strength） Unit cross-sectional area (initial width) of the film before tensile fracture The maximum tensile force that can be sustained by (thickness), usually measured in units ofMPaorN/mmThe core indicator for measuring the "tensile strength" of films, such as food packaging films, requires sufficient tensile strength to avoid tearing during transportation.

Elongation at break（Elongation at Break） The relative increase in length (based on the initial length) of a film when stretched to fracture, usually expressed as a percentage（%）Expressed. Reflecting the "toughness and ductility" of the film, such as the need for a certain elongation at break for cling film to adapt to the curved wrapping of fruit surfaces.
