1. Material Comparison: Performance Characteristics of Different Materials
PETG: High transparency and strong chemical resistance, suitable for high-end skincare packaging.
PP: Lightweight, good heat resistance, commonly used for lotion bottles and spray bottles.
PE: Soft and good toughness, often used for tube packaging.
Acrylic: High-quality texture and good gloss, but higher cost.
Straw-based: Environmentally friendly and biodegradable, suitable for brands pursuing sustainability.
2. Production Process Analysis
Injection Molding: Molten plastic is injected into a mold to form, suitable for mass production.
Blow Molding: Plastic is blown into a bottle shape using air pressure, suitable for hollow containers.
Mold Control: The precision of the mold directly affects the appearance and quality of the bottle, with errors needing to be controlled within 0.01mm.
3. Quality Testing Standards
Sealing Test: Ensures that liquids do not leak.
Compression Test: Simulates the squeezing conditions during transportation.
Appearance Inspection: Checks for defects such as bubbles, scratches, etc.
4. Advantages of Skincare Packaging
Appearance Design: High transparency and fine texture enhance the product’s grade.
Functionality: Designs like pumps and droppers make it convenient to use and allow precise dosing.
Sealing: Prevents oxidation and contamination, extending the product’s shelf life.
Safety: Meets food-grade standards, ensuring it is harmless to the human body.
