Introduction
In the Sterile Processing Department (SPD), safety is
paramount. Plastics are identified by the Resin Identification Code, which is
any number between 1 to 7 stamped between a triangle made by arrows. The
following are the types of plastics and their codes.
#1 PET (Polyethylene Terephthalate)
#2 HDPE (High-Density Polyethylene)
#3 PVC (Polyvinyl Chloride)
#4 LDPE (Low-Density Polyethylene)
#5 PP (Polypropylene)
#6 PS (Polystyrene)
#7 Polycarbonate

The choices we make regarding the materials used for storing
and handling medical tools directly affect patient outcomes. As SPD educators,
it is essential to ensure that our teams understand which materials are safe
and compliant with health standards. Food-grade plastic resins offer a reliable
solution for reducing contamination risks while maintaining hygiene.
Key Food-Grade Plastics Used in Healthcare
1. High-Density Polyethylene (HDPE) - #2
High-density polyethylene is indispensable in healthcare.
Its strength, chemical resistance, and non-toxic properties make it ideal for
various applications, from storing sterile instruments to packaging medical
products. HDPE is safe for contact with medical devices as it resists leaching
chemicals, ensuring patient safety. It’s also durable and moisture-resistant,
which enhances its utility in medical settings [3].
2. Polypropylene (PP) - #5
Polypropylene's heat and chemical resistance makes it perfect
for medical trays, containers, and autoclaved items. It’s also food-safe, which
means it doesn’t release harmful substances when it comes into contact with
medical devices. As SPD educators, it's crucial to communicate the benefits of
using PP in maintaining sterility and preventing contamination [1].
3. Low-Density Polyethylene (LDPE) - #4
Low-Density Polyethylene is a flexible, yet robust plastic
often found in medical tubing and sterile wraps. LDPE’s non-reactivity and
moisture resistance are vital in protecting medical devices from bacterial
growth. Its food-grade designation makes it a reliable material for
environments requiring the highest hygiene standards [3].

Educating SPD Technicians on Safe Material Use
SPD educators play a critical role in promoting the correct
use of food-grade plastics. [2].By choosing these materials, we reduce the risk
of chemical exposure and contamination, safeguarding both healthcare workers
and patients. Understanding the characteristics of different plastic resins
ensures that SPD technicians maintain a safe and compliant environment in all
operations, contributing to better patient outcomes.
