Adhesive Tape Package Production via Batch Bonding and Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing pressure-sensitive adhesive tape packages are inefficient in mass production due to the need for complex facilities to handle separate release sheets and adhesive tapes, leading to increased costs and reduced efficiency.
Innovation Solution
A method involving feeding adhesive tapes to a release sheet base material, bonding them with predetermined spaces, folding, sealing, and temporarily attaching parts to form a two-folded package, which is then cut to create multiple packages in a single operation, improving production efficiency by eliminating the need for separate handling of release sheets and adhesive tapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive tapes and release sheets are handled separately in conventional production methods, then individual packaging can be achieved, but production efficiency decreases and facility complexity increases
Solution Approach 1:
The invention merges the release sheet and adhesive tape into a single integrated structure where multiple adhesive tapes are bonded to a single release sheet base material. This integration eliminates the need for separate handling of release sheets and adhesive tapes, allowing batch processing and significantly improving production efficiency while reducing facility complexity
Solution Approach 2:
The release sheet base material is divided into multiple sections with predetermined spaces between them, allowing individual adhesive tapes to be bonded to specific sections. This segmentation enables batch processing of multiple tapes simultaneously while maintaining the ability to separate and package them individually
2Productivity
If multiple adhesive tapes are bonded to a single release sheet in batch, then production efficiency improves, but spacing and positioning precision must be maintained
Solution Approach 1:
The invention incorporates a predetermined space between adjacent adhesive tapes during the bonding process. This preliminary spacing arrangement ensures that when the release sheet is folded and sealed, the adhesive tapes are properly positioned without overlapping or excessive gaps, maintaining manufacturing precision while enabling batch processing

AI summary
An object of the present invention is to provide a method for producing a pressure-sensitive adhesive tape package suitable for mass production. The production method according to the present invention aims at producing a pressure-sensitive adhesive tape package which is a pressure-sensitive adhesive tape package 10 accommodating a pressure-sensitive adhesive tape 14 having a support 18 and an adhesive agent layer 12 provided on one surface of the support 18, the pressure-sensitive adhesive tape package comprising a release sheet 16 to which the adhesive agent layer of the adhesive tape is releasably attached. In this method, the adhesive tape 14 is bonded to the release sheet base material 116, and folded in two. Subsequently, a plurality of adhesive tapes 14 is heat sealed and temporarily attached to one release sheet base material 116, and the release sheet base material 116 is cut.
