Frequently Asked Questions
A 3-ply laminate has three film layers bonded with two adhesive layers. Common structures include PET/MET PET/PE for barrier packaging and PET/ALU/PE for high-barrier applications.
A 3-ply structure has two bond points, so total adhesive is typically 4.5 to 6.0 GSM (2.0–3.0 GSM per bond). The default is 5.0 GSM total.
PET/MET PET/PE for snacks and coffee, PET/ALU/PE for pharma and retort, BOPP/MET BOPP/PE for flexible wrapping with barrier.
