Abstract

The invention provides a device for detecting the moisture permeability of an aluminum-plated polyethylenetherephtalate (PET) thin film, belongs to the technical field of machinery, and solves the technical problems that the moisture permeability of the aluminum-plated PET thin film can not be detected and the like in the prior art. The device comprises a base and a vertical column vertically fixed on the base, wherein a positioning clamp capable of positioning the aluminum-plated PET thin film is arranged on the base and comprises a base plate; the base plate is fixed on the base; a humidity sensor and a programmable logic controller (PLC) are arranged on the base plate; the humidity sensor is connected with the PLC through a line; the PLC is provided with an output port connected with a computer; and a water spraying mechanism for spraying water to the aluminum-plated PET thin film positioned by the positioning clamp is also arranged on the base. The device can detect the moisture permeability of the aluminum-plated PET thin film and is high in accuracy.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a detection device, in particular to a detection device for moisture permeability of an aluminized PET film. Background technique [0002] With the improvement of people's living standards, fruit packaging materials have become more and more popular in people's daily life. The fresh-keeping performance of fruit packaging materials has an important impact on product protection, product circulation and shelf sales. [0003] PET film is a kind of packaging film with relatively comprehensive performance. It has good transparency and luster; it has good air tightness and fragrance retention; it has moderate moisture resistance, and its moisture permeability decreases at low temperatures. Moreover, PET film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary fi...
