Buyer analysis
When four-side seal is worth it
Four-side seal packs can improve sample presentation and edge consistency, but the format needs correct film control, registration and sealing pressure. The RFQ should include final artwork or blank film samples.
Multi-lane productivity
High-volume four-side seal projects often move to multi-lane machines. Lane count changes film width, dosing repeatability, cut accuracy and downstream counting needs.
