Description
PMMA is a transparent plastic that offers incredible strength and stiffness and can be optically clear. This transparency makes it easy for advanced vision systems or employees performing physical visual inspections to analyze and monitor food product quality throughout transportation.

PMAMJWJDBDSDHV-UHFFFAOYSA-N
Melting Point
160 °C (320 °F; 433 K)
Application
PMMA is often used to store milk and other dairy products, oils, and feed for animals. Acrylic is also used to create mixing bowls, where transparency can aid mixing and other cooking process applications. PMMA is BPA-free and non-toxic when solid, and it’s so biocompatible that acrylic is frequently used in dentures and cavity fillings.
Chemical Formula
(C5O2H8)n
Feature
The limitations of acrylic include poor impact resistance and limited heat resistance, weakness against attacks by organic solvents, and susceptibility to cracking under pressure due to poor wear and abrasion defense. It’s important to consider these downsides when choosing whether or not to use PMMA for food and beverage packaging purposes.
