Breachable Bubble Opening Device for Polymer Film Packages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging made from polymer films are difficult to open due to their strong seals, which are designed to prevent rupture during packaging and transportation, but this makes them hard for consumers to access the contents without using brute force or scissors.
Innovation Solution
A package design that includes a breachable bubble within a tab area, formed by sealing two flexible polymer films together with an adhesive layer that can bond without elevated temperatures, allowing minimal pressure to separate the films and open the package.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the strength of the film or seals is increased to prevent rupture during packaging and transportation, then the protective quality and reliability are improved, but the ease of opening deteriorates
Solution Approach 1:
The seal is segmented into two distinct zones: a strong seal portion that maintains package integrity during transport, and a weak seal portion that allows easy opening by consumers. This segmentation resolves the contradiction by spatially separating the functions of strength and ease of opening within the same seal structure.
Solution Approach 2:
Different regions of the seal are given different qualities: the strong seal portion uses high-strength adhesive or thermal bonding for reliability, while the weak seal portion uses lower-strength bonding that breaks easily. This local differentiation allows the package to simultaneously achieve both protective quality and ease of opening.
2Manufacturing precision
If strong sealing methods are used to eliminate void space and protect product, then the manufacturing precision and reliability are improved, but the ease of operation deteriorates
Solution Approach 1:
The sealing process creates distinct strong and weak seal portions through segmented sealing patterns or varying seal parameters in different zones, enabling both high manufacturing precision for package integrity and ease of opening through the weak portion.
Solution Approach 2:
The weak seal portion is intentionally designed with partial sealing strength - sufficient to maintain basic package integrity but deliberately insufficient to prevent easy opening. This partial action resolves the contradiction between seal integrity and ease of opening.
3Reliability
If the adhesive strength is increased to bond films securely, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The adhesive layer is applied with locally varying properties: strong adhesive in the strong seal portion for reliable bonding, and weak adhesive in the weak seal portion for easy opening. This local quality differentiation resolves the contradiction between bond strength and ease of opening.
Solution Approach 2:
Adhesive parameters such as adhesive type, thickness, or curing conditions are changed between the strong and weak seal portions. The weak portion uses parameters that result in lower bond strength, enabling easy opening while the strong portion maintains high reliability.
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 opening of packages with a distinct sound when the bubble breaches, providing access to the contents without the need for scissors or force, while maintaining the protective qualities of the polymer film packaging.
Implementation Method 1
an adhesive layer providing a seal between the first film and the second film. The adhesive layer may have a chemical composition such that it can bond to itself without the application of elevated temperatures
Implementation Method 2
Sufficient fluid may be trapped within the breachable bubble that the bubble breaches upon application of minimal pressure by a user, separating a sealed portion of the first film from the second film

AI summary
A package and a process for forming the package are provided. The process may include providing a first flexible polymer film and a second flexible polymer film, sealing the first film and the second film together to form an enclosure and at least one tab area, and trapping fluid within a discrete portion of the tab area to form a breachable bubble. The enclosure may define an interior volume configured to receive a consumer product. Fluid trapped within a discrete portion of the tab area to form a breachable bubble may be sufficient to cause the bubble to breach upon application of minimal pressure by a user, separating a sealed portion of the first film from the second film.
