Abstract

The invention relates to an easy-to-tear type drug packaging composite film for an automatic drug dispensing machine. The preparation method of the easy-to-tear type drug packaging composite film comprises the following steps: coating the surface of a polyester film to change the molecular structure of the polyester film; then, gluing the treated polyester film through a gluing device and drying; adding a lot of low-temperature heat-sealing materials in the film blowing process of the polyester film to obtain a low-temperature heat-sealing film; printing and compositing the polyester film (PET) and a polyethylene film (LDPE) to obtain a composite film, and finally performing curing, slitting, bag making, edge folding and packaging, so that the low-temperature heat-sealing easy-to-tear type composite film is obtained. The composite film overcomes the defects that in the prior art, the composite film is not easy to tear, used glass paper is high in cost, and the hot-sealing temperature is high. The composite film is good in application performance, convenient for packaging, good in moisture resistance performance, light in materials and good in drug resistance, thereby effectively protecting the quality of drugs, and being particularly suitable for being used in hospitals.

Description

technical field [0001] The invention relates to the technical field of medicine packaging, in particular to an easy-to-tear medicine packaging composite film for an automatic medicine dispensing machine. Background technique [0002] Fully automatic medicine dispensing machines have been widely used in hospitals in Europe, South Korea, Taiwan and other places. It can not only improve the work efficiency of the hospital, but also reduce the error rate. It only needs to transmit the prescription information to the "automatic" after the patient pays the payment. Medicine filling machine", the automatic medicine filling machine will automatically select medicines to improve safety performance. The usage in European and American countries has been stable and has an annual growth rate of 10%. At present, domestic hospitals have also begun to use the automatic drug dispensing machine, and it will definitely be popularized in major hospitals in China in the future. [0003] The us...
