Ornamental Laminate Film Raised Pattern Metallic Luster
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ornamental laminate films fail to achieve a satisfactory ornamental effect while maintaining material strength and barrier properties, as increased three-dimensionality through swelling compromises the thickness and integrity of the packaging material.
Innovation Solution
An ornamental laminate film comprising an inside and outside film with printed letters or patterns and a raised part, featuring metallic luster, varying hue, brightness, and glossiness, where the raised part is formed along the pattern outline, enhancing three-dimensionality without compromising material strength or barrier properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the area or amount of swelling is increased to enhance the ornamental effect, then the ornamental effect is improved, but the thickness of the film is decreased which makes it difficult to maintain material strength and barrier property
Solution Approach 1:
The patent applies local quality by creating raised parts only in specific regions corresponding to letters or patterns, rather than swelling the entire film. This localized embossing technique concentrates the ornamental effect where needed while preserving the thickness and integrity of the rest of the packaging material, thus maintaining both aesthetic appeal and functional properties.
Solution Approach 2:
The patent implements partial action by forming raised parts only on portions of the film that correspond to decorative elements like letters or patterns. This partial embossing approach provides sufficient ornamental effect without the need to swell the entire film area, thereby avoiding excessive thinning and preserving material strength and barrier properties in non-decorated regions.
2Shape
If a laminate film is heat-pressed to make the laminate film partly swell, then three-dimensionality of the letter or mark is achieved, but the ornamental effect may not be fully satisfactory
Solution Approach 1:
The patent enhances the ornamental effect by combining the three-dimensional raised parts with color printing. The printed colors on the raised surfaces create visual contrast and depth perception, making the letters or marks more aesthetically pleasing and visually striking beyond what three-dimensionality alone can achieve.
Solution Approach 2:
The patent merges two techniques - heat pressing to create three-dimensional raised parts and printing to add color - into a single integrated decorative solution. The combination of tactile three-dimensionality and visual color enhancement produces a synergistic ornamental effect that is more satisfactory than either technique alone.
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 enhances the ornamental effect by emphasizing the raised part with metallic luster and color contrast, while maintaining mechanical strength and barrier properties, making it suitable for practical use in pouch-type containers and sealing materials.
Implementation Method 1
a laminate film made from a plurality of films different from each other in the thermal expansion coefficients is heat-pressed to make the laminate film partly swell

AI summary
The present invention relates to an ornamental laminate film made from at least an inside film and an outside film, provided with a letter and/or a pattern by printing and as a raised part protruding toward the outside film. At least apart of the letter and/or the pattern has a metallic luster and differs in at least one of hue, brightness, chroma and glossiness from a region other than the letter and/or the pattern, and the raised part is formed along at least a part of the letter and/or the pattern. As a result of that, an ornamental laminate film with excellent design is provided without impairing its function as a packaging material.
