HDPE
HDPE (High-Density Polyethylene) is a common type of plastic material widely used in packaging and manufacturing. It's known for being strong, durable, and resistant to many chemicals. Think of it as a versatile plastic that can be used to make everything from milk jugs to industrial containers. Companies often mention HDPE in job descriptions when they're looking for people who understand packaging materials, especially for food, beverage, chemical, or consumer goods packaging. It's similar to other packaging materials like PET (used in soft drink bottles) or PP (used in food containers), but HDPE is especially valued for its strength and safety for food contact.
