Reclosable Package With Segmented Adhesive Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging solutions for food and non-food products often require tools for opening and lack easy-reclosable features, compromising hermeticity and convenience, especially in applications like produce and snack food bags.
Innovation Solution
A package design featuring a pouch with a discrete tape and die-cut segment, allowing manual opening and reclosing without tools, using pressure-sensitive adhesive for easy-open and reclosable functionality, maintaining hermeticity until opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressure sensitive adhesive is used to provide reclosability, then reclosable functionality is achieved, but the adhesive can be contaminated by the contained product compromising reclosability
Solution Approach 1:
The adhesive is segmented into two separate surfaces: one surface contacts the product while the other surface remains protected and clean for reclosing. This segmentation prevents product contamination of the adhesive that needs to maintain bonding capability.
Solution Approach 2:
A release liner acts as an intermediary between the adhesive and the environment, protecting the adhesive from product contamination while allowing the adhesive to perform its bonding function when needed.
2Ease of operation
If traditional closures like zippers or interlocking elements are used, then reclosability is provided, but the device complexity increases
Solution Approach 1:
The complex mechanical closure mechanisms (zippers, interlocking elements) are extracted and replaced with a simple adhesive-based system. The essential reclosing function is retained while eliminating unnecessary mechanical complexity.
Solution Approach 2:
The closure mechanism transitions from mechanical interlocking to chemical adhesion, changing the fundamental parameter of how the package is closed. This simplifies the device while maintaining reclosability.
3Ease of operation
If adhesive is positioned close to the product, then reclosability is achieved, but the adhesive is contaminated by the product compromising hermeticity
Solution Approach 1:
The adhesive system is segmented into product-contact and non-product-contact surfaces, allowing the adhesive to be positioned close to the product for reclosability while preventing contamination that would compromise hermeticity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy manual opening and repeated reclosing of packages, maintaining hermeticity until use, without the need for zippers or interlocking closures, and can be integrated into existing packaging processes with minimal equipment modifications.
Implementation Method 1
at least a first portion of the first surface is coated with a pressure sensitive adhesive

AI summary
An easy-open and reclosable package includes a pouch including a discrete tape including a base strip between first and second side panels; at least a first portion of the first surface of the strip coated with a pressure sensitive adhesive and adhered by the adhesive to the inner surface of the first panel at a first location, and a second portion of the first surface of the strip anchored to the inner surface of the first panel at a second location; a die cut in the first panel, the die cut defining a die cut segment, the die cut segment so arranged that when the package is opened, it can be reclosed by adhering at least one of the first and second panels to the adhesive; and a product in the pouch.
