LDPE is described as which of the following?

• A. Brittle and heat sensitive
• B. Tough, highly chemical resistant, and can be translucent not very rigid e.g. General packaging
• C. Very rigid and opaque
• D. Poor chemical resistance

Answer: (B)

LDPE is a flexible, tough polymer with good chemical resistance and often a translucent appearance. The branching in LDPE reduces how tightly the molecules pack, so the material stays soft and bendable rather than rigid. This makes it ideal for general packaging like films and bags, where clarity and the ability to seal and bend are important. It isn’t brittle, it isn’t very heat sensitive in a way that would make it fail under typical packaging use, and it isn’t a rigid, opaque plastic, nor does it have poor chemical resistance.
