Macaron Packaging with Segmented Cover Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions for macarons face challenges such as complexity in filling, exposure of all products when the sealing cover film is removed, and issues with maintaining crispness due to moisture migration, as well as the fragility and breakability of macarons, which are not adequately addressed by current thermoplastic containers and cardboard cover films.
Innovation Solution
A thermoplastic container with rows of individual compartments sealed by a transparent cover film, featuring micro-perforations along the weld lines to allow separate opening of rows, ensuring the packaging remains closed until consumption and minimizing moisture migration, while using a multi-layer material system for enhanced protection and freshness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single sealing cover film is used for the entire container, then the packaging structure is simple, but all compartments are opened when the cover film is removed, exposing all products
Solution Approach 1:
The continuous sealing cover film is divided into multiple separate film portions, each corresponding to a specific row of compartments. This segmentation allows individual rows to be opened independently by removing only the relevant film portion, while other rows remain sealed. The weakening edges are positioned at the sealed joints between rows, enabling controlled separation of film portions without compromising the sealing integrity of other sections.
2Reliability
If macarons are placed in individual compartments, then damage during transport is reduced, but the packaging complexity increases
Solution Approach 1:
The container is divided into multiple rows of individual compartments, with each compartment designed to hold a single macaron. This segmentation provides individual protection for each macaron during transport and handling, preventing damage while maintaining organization and accessibility.
3Ease of manufacture
If the cover film is made transparent, then product visibility is improved, but moisture migration from filling to dough cookies increases
Solution Approach 1:
The packaging system uses a composite structure combining a transparent container body with a separate transparent cover film. The transparency of both components allows product visibility, while the sealed joint between the container and cover film creates a moisture barrier that prevents migration from the filling to the dough cookies, addressing both visibility and moisture protection requirements.
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
The solution effectively limits moisture migration, reduces macaron damage during transport, and maintains freshness by allowing controlled opening of rows, ensuring the macarons remain crispy and undamaged until consumption.
Implementation Method 1
each layer being sealed by means of a sealed joint with a transparent cover film
Implementation Method 2
the cover film is provided with one or more weakening edges on the sealed joint wherein the rows can be opened separately at different times

AI summary
The present invention relates to a packaging device and a packaging method for macarons, comprising a container or tray made of thermoplastic and transparent material and provided with a number of rows of single compartments, each compartment housing one macaron in an upright or lying position, and wherein several rows next to each other in one plane describe a layer, which layer is sealed by means of a sealed joint with a transparent cover film wherein the cover film is provided with one or more weakening edges on the sealed joint wherein the rows can be opened separately at different times, so that these rows remain closed until they are actually consumed.
