low-density polyethylene

polymer

Low-density polyethylene (LDPE) is a semi-crystalline thermoplastic polymer characterized by a branched molecular structure that gives it flexibility and impact resistance at ambient temperatures. It is widely used in flexible packaging films, plastic bags, tubing, and squeeze bottles across the food, pharmaceutical, and consumer goods industries, where its combination of processability, chemical resistance, and low cost make it the preferred choice over more rigid or expensive alternatives. Engineers select LDPE when flexibility, ease of processing, and cost-effectiveness are priorities, though its lower stiffness and heat resistance compared to high-density polyethylene limit its use in structural or high-temperature applications.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
