Material
PET
Clear, light, food-grade, recyclable. The default for anything the customer must see.
What It Is Good At
Clarity, weight, cost. A 500 ml bottle at 20–28 g; the standard stream recycles it.
Where It Stops
Heat above about 60 °C, strong solvents, and a thick-wall premium look — PET goes cloudy when thick.
Typical Use
Shampoo, water, juice, toner, sanitizer.
Next Step
