Is paper-plastic laminate suitable for a standard heat-sealing packaging machine?
• Paper-plastic laminate has a paper layer; standard heat-sealers need impulse or ultrasonic sealing to avoid charring fibers.
• Standard constant-heat sealing requires 120-160°C, 0.2-0.4MPa, and low film tension for paper-plastic.
• If laminate has a PE inner layer, trial runs are possible; pure paper without sealant cannot be sealed.
• Require supplier samples with heat-seal strength ≥1.5N/15mm and verify via FAT before purchase.
• Retrofitting a standard sealer is costly; choose a servo-driven, pressure-adjustable pillow packaging machine.
