1. Raw Material Preparation
Purchase raw materials.
Use high-quality low-density polyethylene (LDPE) as the main raw material.
2. Extrusion Foaming Molding
Melting and extrusion system: Adopt a twin-screw extruder with zone temperature control.
Zone 1: 120℃ (preheating)
Zone 2: 150℃ (melting)
Zone 3: 180℃ (plasticizing)
Maintain melt pressure at 15-20MPa.
Control extruder speed at 50-70rpm.
Bubble forming process: Molten material forms two layers of film through a special mold.
The lower film forms bubble prototypes via vacuum adsorption.
Heat sealing and compounding are done before bubbles fully cool.
Control cooling roller temperature at 15-20℃.
3. Subsequent Processing
Corona treatment: Treatment power 4-6kW; Treatment speed 10-15m/min.
Winding and slitting: Adopt a constant tension automatic winding system.
Slitting accuracy: ±0.5mm.
Online detection system monitors thickness uniformity in real time.
Quality inspection: Check bubble integrity for each roll.
Conduct random drop tests (1m height, 3 consecutive times).
1. Electronic Product Packaging
LCD display devices: Suitable for transportation protection of 32-85 inch LCD screens.
Form a buffer layer between the screen surface and the packaging box.
Anti-static type is used for sensitive displays like OLED.
