Overview
A yet2 client is seeking technologies capable of decorating the surface of plastic containers or packaging products for the food, personal care, and home care sectors.
Background
This organization is looking for chemicals, adhesives, or sets of systems capable of being jettisoned digitally at high speed through an inkjet printer onto a transfer medium and then subsequently transferred onto a plastic product.
Ideal solutions will be pressure-sensitive adhesives that bond to the surface tension of the cured inks, but also provide high shear and bond strength to plastic containers.
Innovative solutions that circumvent the need for a transfer medium or require an alternative transfer medium will also be considered granted they meet the rest of this organization’s requirements.
Constraints:
Potential solution must-haves:
- Capable of decorating the surface of 3D plastic containers with multicolored, high-resolution designs.
- Capable of being jettisoned digitally at high speed.
- Low viscosity – Less than 20cPs (with 55ºC @ 30 rpm Brookfield test conditions)
- Storage modulus higher than 105 Pa
- Fast initial cure time (< 1 second)
- Full cure developed within 24 hours.
- Capability to be transferred to Polyester.
- Provide sufficient hardness, durability, and scratch resistance.
- No toxicity
- Stability at 55-66°C
- Meet REACH and TSCA regulatory requirements
Potential solution nice-to-haves:
- A single cure trigger
- Work in ambient environments (e.g., does not require a 100% nitrogen environment, etc.)
- Recyclable (Label can be removed)
- Ability to be applied on a non-cylindrical surface
- Little or no odor
- Food-safe materials
Possible Solution Areas
- UV-Curable Ink
- Digital inkjet transfer printing
- Label-less printing
- Pressure-sensitive adhesives
This project will finish by May, please contact us before then.
