Which Laminate Structure Should You Use? | Barrier, Sealant & Thickness Explained
Choosing the wrong laminate means either a failed product (rancid snacks, soft biscuits, leaking pouches) or money wasted on barrier you don't need. In this 5-minute video you will learn how to pick the right structure: the three jobs of every laminate, the six questions to ask before you choose, which film stops oxygen and moisture (OTR / WVTR compared), the structure ladder from BOPP/PE to PET/ALU/NY/CPP, typical structures by product, how to choose the sealant and its thickness, common selection mistakes, and the six tests to run before approval.

QUICK GUIDE
Outer layer = print & look (PET / BOPP) · Barrier layer = protects product (MET-PET / ALU / NY) · Sealant = seals & strength (PE / CPP)
Structure ladder: BOPP/PE (₹) › PET/MET-PET/PE (₹₹) › PET/ALU/PE (₹₹₹) › PET/ALU/NY/CPP (₹₹₹₹)
Sealant thickness (typical): up to 100 g 40-50 µ · 100-500 g 50-70 µ · 0.5-1 kg 70-90 µ · 1-5 kg 90-120 µ
Barrier values shown are typical indicative figures for learning; always confirm with supplier data sheets and shelf-life tests.
