AI Technical Summary

Technical Problem

Existing blister packaging methods face challenges in minimizing scrap while ensuring the registration mark functions properly and does not degrade the appearance of the blister sheet, as reducing the blister film width causes the die-cutting line to overlap with the registration mark, and reducing the registration mark size hinders its detection.

Method used

A method for manufacturing blister sheets where the cover film is attached to the container film such that the registration mark is positioned to remain entirely in the scrap area, with at least a portion in a triangular region, and the relative positions are adjusted to prevent overlap with the die-cutting line, ensuring the mark's functionality and reducing scrap effectively.

Benefits of technology

This method ensures the registration mark does not remain on the blister sheet, maintains its functionality, and significantly reduces scrap, addressing the appearance and cost concerns of traditional methods.

Abstract

To provide a method for manufacturing a blister sheet etc. that can properly exert the function of a registration mark and can effectively reduce scrap generation.SOLUTION: A PTP sheet as a blister sheet is produced by punching out a PTP film 6 obtained by attaching a cover film 4 to a container film along predetermined punching lines Rp. Registration marks 7 are provided at predetermined intervals on the cover film 4, and the cover film 4 is attached to the container film so that at least a portion of the registration marks 7 is located in a triangular area TA surrounded with two curved lines Rw that are positioned to sandwich the scrap portion of the PTP film 6 that remains after the PTP sheet is obtained, and an extension line Es of the straight line Rs.SELECTED DRAWING: Figure 6
