Comprehensive Guide to Plastic Water Bottle Production Process (Part 3)

There’s a story in every cup, warmth in every life. Hello everyone, "Dong Dong's Cup Talk" is here! Today, we’ll explore how plastic water bottles are made and what key points to note during production. Are you curious? http://www.umbottle.com/ProductsDetail-VB-10504.htmlSome might ask, "Hey, don’t you usually produce stainless steel water bottles? How do you know about plastic bottle manufacturing?" Well, our factory produces both stainless steel and plastic water bottles—and our experience with plastic actually predates our stainless steel production!

Our factory is equipped for both injection molding and blow molding, including one-step and two-step blow molding machines, as well as injection-stretch-blow molding technology.

3. Methods to Distinguish Virgin vs. Recycled Materials

Quick sensory identification:

1. Sight: Virgin PC has >90% transparency; recycled material shows haze >15%.

2. Touch: Virgin TRITAN’s surface friction coefficient is 0.3–0.5; recycled material exceeds 0.7.

3. Sound: Virgin AS produces a crisp "ding" when dropped freely; http://www.umbottle.com/ProductsDetail-VB-10504.htmlrecycled material makes a dull "thud".

4. Smell: Virgin material is odorless at 200°C; recycled emits a pungent, burnt smell.

5. Flexibility Test: Virgin PPSU bends 180° without whitening; recycled cracks at 90°.
