Paper wraps, paper wrapped products, and methods of making the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper wraps fail to securely wrap coreless paper products without twisting and tucking, and often tear easily when bundled, leading to product damage and difficulty in removal, while also causing 'blocking' issues during transportation and storage.
Innovation Solution
The development of paper wraps with selectively applied adhesives on the outside and inside surfaces, allowing the wrap to self-bond and secure around products without a core, ensuring easy removal and minimizing product damage and blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional paper wraps are used without adhesive, then the wrap can be easily removed, but the wrap cannot securely hold coreless products without twisting and tucking
Solution Approach 1:
The patent applies adhesive only to specific portions of the paper wrap (end seals and belly seal areas) rather than the entire surface. This localized adhesive application provides secure holding at critical points while leaving other areas adhesive-free for easy manual removal and opening by consumers.
Solution Approach 2:
The patent uses partial adhesive coverage instead of full coverage, applying adhesive only where structurally necessary to maintain wrap integrity during transport and storage, while avoiding excessive adhesive that would make removal difficult.
2Reliability
If adhesive is applied to secure the wrap, then the wrap stays in place during transport, but the wrap may stick to adjacent products causing blocking
Solution Approach 1:
Adhesive is applied only to specific portions of the wrap that contact the product (end seals and belly seal areas), while edges and outer surfaces remain adhesive-free. This prevents the wrap from sticking to adjacent products during stacking and storage, eliminating blocking issues.
Solution Approach 2:
The patent uses partial adhesive coverage rather than full coverage, applying adhesive only where necessary for structural integrity. This limited adhesive application provides sufficient wrap stability during transport while minimizing the risk of blocking between stacked products.
3Strength
If strong adhesive is used to prevent tearing, then the wrap is secure, but the wrap may damage the product during removal
Solution Approach 1:
The patent applies adhesive only to specific seal areas (ends and belly) rather than across the entire wrap surface. This localized application creates strong bonds where needed to prevent tearing during transport, while avoiding adhesive contact with the product surface that would cause damage during removal.
Solution Approach 2:
The patent uses partial adhesive coverage with controlled adhesive quantity, applying adhesive only to the minimum necessary areas for structural integrity. This prevents excessive adhesive from contacting and damaging the product during wrap removal.
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 provides secure sealing for individual and bundled paper products, preventing unintentional tearing and tampering, while reducing product damage and blocking during handling and storage, and is more environmentally friendly than traditional plastic or poly film wraps.
Implementation Method 1
the printed paper wraps comprise at least one heat-sealable adhesive that may be applied in varying locations, coverage levels, and patterns comprising different seal strengths, which may be sealed using heat and/or pressure external to the products
