Comprehensive Guide to Plastic Water Bottle Production Process (Part 6)

Every cup tells a story, bringing warmth to life. Hello everyone, "Dong Dong's Cup Talk" is here again! Today we'll explore how plastic water bottles are manufactured and the key considerations in production. Some may wonder: "Wait, don't you mainly produce stainless steel bottles? How do you know plastic bottle production so well?" http://www.umbottle.com/ProductsDetail-VB-10424.htmlActually, our factory has been making plastic bottles longer than stainless steel ones - we're experts in both!

Our facility handles both injection molding and blow molding, including single-stage and two-stage blow molding, plus injection-stretch-blow molding. http://www.umbottle.com/ProductsDetail-VB-10424.htmlWhether you need plastic mold development, product injection molding, bottle processing, or custom plastic solutions, we can help! (And no, this isn't an ad - really, not an ad! Haha.)

6. Special Analysis of PS Tapered Iced Beverage Cups

1. Design Advantages

- 8° Taper: Ergonomic grip angle

- Gradual Wall Thickness:

- Rim: 1.8mm → Base: 2.2mm

- Passes 1.5m drop test

2. Usage Guidelines

- Temperature Limit: ≤60°C liquids (PS glass transition temp: 95°C)

- Service Life: 6 months recommended http://www.umbottle.com/ProductsDetail-VB-10424.html(UV exposure accelerates yellowing)

3. Safety Warnings

- Inner wall turns cloudy (molecular chain breakdown)

- Rim deformation >0.5mm http://www.umbottle.com/ProductsDetail-VB-10424.html(seal failure)

- Surface cracks >2mm long

4. High-Temperature Risks

- Above 80°C, PS accelerates BPA migration (EU 10/2011 limit: 0.6mg/kg)

- Recommended max liquid temperature: http://www.umbottle.com/ProductsDetail-VB-10424.htmlbelow heat deflection temp (82°C)

Key Considerations for Quality Plastic Bottles

When purchasing, focus on:

✅Material Certification (FDA/LFGB)

✅ Molding Quality (no burrs/sink marks)

✅ Functional Suitability http://www.umbottle.com/ProductsDetail-VB-10424.html(temperature/chemical resistance)

Understanding plastic products scientifically helps dispel misconceptions while maximizing their advantages: lightweight, safe, and eco-friendly.
