Packaging stretch wrapper YG series

Product overview
Purchasing an industrial stretch film machine is a major investment for packaging lines and plants. This document summarises key design choices, performance attributes and selection criteria from YG Machinery to help production managers reduce scrap and optimise output.

Cast-type stretch film machine
Cast extrusion lines use a flat T-die and water-cooled chill rolls to produce films with superior clarity and lower resin crystallinity. The cast design increases puncture resistance by over 30% compared with blown-film systems and supports stable line speeds above 200 m/min when paired with an efficient extrusion line.

Core applications

• Pallet wrapping: Produces 15–25 µm hand and machine wraps to secure goods for ocean and land transport.
• Food packaging: Works with PVC extrusion or dedicated PE screws to produce crystal-clear cling film for food protection.
• Electronics protection: Produces anti-static stretch films to prevent dust adhesion and static build-up.
• Heavy machinery packaging: Integrates with bubble-film or air-column systems to provide multi-layer cushioning.

Key selection parameters

• Screw L/D ratio: 30:1 or 32:1 recommended for uniform plasticization and melt homogeneity.
• Automatic winding: Automated roll changers reduce manual handling by ~80% and minimise scrap during roll swaps.
• Temperature control: PLC-based temperature management keeping variations within ±1°C prevents uneven film thickness.

Pro tips

• For packaging sharp metal parts, select 3-layer or 5-layer co-extrusion models to improve tear resistance.
• Confirm die-adjustment bolts and contact surfaces use hot-work die steel to limit premature wear.
• Use inline edge-trim recycling (edge-trim crusher) to reduce resin waste and lower material costs.

Case study
A Southeast Asian factory replaced an older line with a high-precision stretch film machine from YG Machinery featuring an optimized screw design and an edge-trim recycling system. Scrap rate fell from 18% to below 2% and daily output increased by 120%.
