Vinyl Acetate Ethylene Copolymer Film for Non-PVC Graphic Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for environmentally friendly, non-PVC films that offer properties comparable to PVC films, particularly in graphic and wall covering applications, due to PVC's undesirable by-products when burned and environmental concerns.
Innovation Solution
The development of films using vinyl acetate containing polymers, such as Vinyl Acetate Ethylene (VAE) Copolymer, combined with additives like titanium dioxide, surfactants, and UV absorbers, which are processed into strengthening and print receptive layers, enabling films with high tensile elongation and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If PVC films are used, then flexibility and conformability are improved, but environmental harm increases due to undesirable by-products when burned
Solution Approach 1:
The patent changes the chemical composition parameters by replacing PVC with vinyl acetate containing polymers (such as VAE copolymer with 60-95% vinyl acetate content) to eliminate harmful halogen by-products while maintaining the desired flexibility and conformability properties through appropriate polymer selection and plasticizer incorporation
Solution Approach 2:
The patent creates composite non-PVC films by combining vinyl acetate containing polymers with plasticizers, pigments, and other additives to achieve a material that replicates PVC's superior flexibility and conformability while being environmentally friendly and free from harmful combustion by-products
2Object-generated harmful factors
If non-PVC films are developed, then environmental friendliness is improved, but comparable properties to PVC films need to be achieved
Solution Approach 1:
The patent adjusts composition parameters by using vinyl acetate content between 60-95% in the copolymer to achieve optimal balance between environmental friendliness and mechanical properties, ensuring the non-PVC film exhibits durability, flexibility, and conformability comparable to traditional PVC films
Solution Approach 2:
The patent develops composite formulations combining vinyl acetate containing polymers with specific plasticizers and additives to replicate PVC's reliable performance characteristics while maintaining environmental friendliness, achieving comparable tensile strength, flexibility, and weather resistance
3Object-generated harmful factors
If vinyl acetate containing polymer is used, then environmental friendliness is improved, but film durability and printability need to be ensured
Solution Approach 1:
The patent creates composite film formulations combining vinyl acetate containing polymers with durability-enhancing additives such as UV absorbers, fire retardants, and coupling agents, along with print-receptive components, to ensure the environmentally friendly film achieves both long-term durability and excellent printability for graphic applications
