Formulation of bio-based Ink
Derived chemically from plants
The raw material of Bio-based ink is come from renewable starch sugar such as castor, corn, sugarcane, and tapioca. The production process is clean and green.
- Bio-based
heat transfer
S.E.C. is proud that we can offer the Vegan Transfer with patent bio-based ink. The bio-based ink with new type of bio-based synthetic. The raw material is a bio-based elastic polymer with heat resistance, derived chemically from plants, and is invented and developed as eco-friendly materials for printing heat transfer with strong adhesion on garment, replacing conventional petroleum-based printing.

In-house washing test:
By using 60ºC machine wash and tumble dry x 10 cycles Result: No peel off, cracking, shrinkage, wrinkle and color migration. Washing test report of sponsor’s in-house washing test. Testing item was fabric adhered with bio-based heat transfer prepared by bio-based printing ink and eco-friendly adhesive.
Energy Saving with Microwave Curing
The production process of heat transfer is also energy consuming because it requires multiple layer, printing and oven drying and curing is required after printing each layer. Large amount of energy is consumed in the whole process. In order to reduce the amount of energy use, microwave will replace thermal as the heating source in the process of drying and curing.
