The FTSE-linked equity income plan offers an annual yield of 7.6% and has a 60% barrier against downside risk.
Meanwhile, the Enhanced Growth Plan offers a maximum potential return of 70% over six years, plus a 50% downside barrier.
The six-year Equity Income Plan – FTSE-100 series 6, offers fixed income of 1.9% per quarter and full repayment of capital unless the FTSE 100 falls more than 60% below its starting level on any quarter end date and fails to recover above the initial level at maturity.
Incapital said this barrier is deeper than the 50% level typically used in structured investment products.
The Enhanced Growth Plan – Inflation-linked series 1 offers the potential for two times the rise of the index over six years, capped at 70%.
Its minimum return will be the change in the Retail Prices Index over that period, as long as the FTSE 100 remains at or above 50% of its initial value at maturity.
Both plans are open with immediate effect, with a strike date of 18 November. The Enhanced Growth Plan offer closes on 7 November and the Equity Income Plan closes on 11 November.
James Chu, managing director of Incapital Europe, said: "Investors are looking for investment strategies that can deliver high income or a growth solution that can protect their wealth against inflation.
"We have been able to produce plans which address those concerns and offer protection against stock market risk at defined levels using a barrier of up to 60% on our income plan and 50% on the growth plan."
The plans are available for direct investments and through ISAs or ISA transfers, with a deadline for transfers of 28 October for Enhanced Growth and 4 November for Equity Income.
Explicit charges on the plan are zero and standard commission for intermediaries is 3%, which can be rebated.
