Practical tools for plant teams, job seekers, and self-learners. Started from 9 years in flexible packaging at UFlex, JPFL & GLS — now built for professionals everywhere by Vivek Kumar (M.Tech, NIT Uttarakhand).
Industry tools from flexible packaging experience — plus mentorship and career tools for everyone.
Free online calculators for flexible packaging professionals. Calculate film roll weight, length, OD, GSM, yield, Met capacity, converting capacity and more.
W = L × W/1000 × μm/10⁶ × ρ
L = W / (W/1000 × μm/10⁶ × ρ)
OD = √((4×L×μm)/π + (Core ID + 2×Wall)²)
GSM = Micron × Density (g/cm³)
Yield = (Output ÷ Input) × 100
Running ÷ Shift × 100
₹/sqm = ₹/kg × GSM ÷ 1000
3-Step: Cycle → Rolls/day → MT/day
All machines → MT/day · plant bottleneck
Apps for life beyond work — habit trackers, fun activities, games, and efficiency boosters. Built from personal needs, shared free with everyone.
Finance, fitness, animated stories, productivity and everyday life — every channel and playlist gathered in one place.
Insights from 9 years in flexible packaging, tech tutorials, Excel tips, and industry knowledge — shared freely for the community.
Have a problem that needs a digital solution? Vivek will build it completely free for you. If others want to use it, a fair profit-share model applies.
The person who requested the app always gets it free — no conditions.
If other users benefit commercially, a transparent revenue-share model applies.
Every app built with M.Tech-level knowledge and 9+ years of domain experience.
Packaging, farming, education, health, finance, games — no domain is too niche.

I'm a Mechanical Engineer by training, a Flexible Packaging professional by career, and an app builder by passion. After 9 years working at UFlex Limited, JPFL Films, and GLS Polyfilms, I've experienced first-hand the daily inefficiencies that slow down professionals in this industry.
That frustration became fuel. I began building tools to automate repetitive calculations, streamline quality processes, and reduce manual errors. What started as personal tools slowly grew into something worth sharing.
Beyond the industry, I love building apps that make everyday life more organised, more fun, and less stressful. VKS Tech (vkstech.com) is the home for all of it.
