I Built a Free Packaging Calculator for Custom Pouch Buyers

I recently built PouchCalc, a free packaging calculator and dieline request tool for custom pouch packaging projects.

Why I built it

In custom flexible packaging, many mistakes happen before production starts.

Buyers often begin artwork before confirming:

• pouch size
• bottom gusset
• material structure
• mylar bag thickness
• zipper position
• valve position
• dieline layout

This can cause wrong dimensions, poor shelf display, artwork mistakes, and production delays.

I wanted to create a simple tool that helps buyers, designers, and small brands plan packaging before requesting a quote or sending final artwork.

What PouchCalc includes

PouchCalc currently includes:

• Stand up pouch size calculator
• Mylar bag thickness converter
• Packaging material selector
• Shrink sleeve size calculator
• Free dieline request page
• Packaging guides for coffee bags, mylar bags, food pouches, and flexible packaging

Example use cases

A packaging buyer can use it to estimate:

• what size pouch may fit 250g coffee
• how to compare micron and mil thickness
• whether PET / VMPET / PE or PET / AL / PE is more suitable
• what information is needed before requesting a custom dieline
• how to plan pouch structure before artwork

What I am improving next

I am currently working on:

• better calculator UX
• more packaging material guides
• more custom pouch examples
• cleaner mobile UI
• better SEO structure for packaging topics
• more useful resources for packaging buyers and designers

Feedback welcome

I would love feedback from builders, designers, and product people:

• Is the homepage clear?
• Is the calculator flow easy to understand?
• Does the site feel useful for packaging buyers?
• What would make the tool more trustworthy?
