HDPE has a more linear and compact molecular structure, which gives it greater mechanical resistance, as well as greater rigidity, hardness and opacity compared to other types of polyethylene. This material is widely used in the production of bottles, tanks, pipes and technical films.
HDPE can withstand higher temperatures than LDPE, resisting up to 120°C for short periods, compared to 80°C for low-density polyethylene.
In the packaging sector, thanks to its high mechanical resistance, HDPE is used for the production of envelopes and bags intended for the transport of heavy materials, which require greater consistency to avoid damage or accidental openings.
This material is also non-toxic and suitable for contact with food, respecting food safety regulations and guaranteeing the absence of contamination risks.
Furthermore, HDPE has the advantage of being resistant to chemical agents, including aggressive substances such as alcohol and petrol, which do not alter its molecular structure.
Both HDPE and LDPE are odorless and tasteless materials, ideal for packaging food products without altering their organoleptic properties. Like other types of polyethylene, HDPE can be sterilized with the most common sterilization methods.
Peculiar characteristics of HDPE polyethylene:
- High stiffness, hardness and opacity;
- High temperature resistance, up to 120°C for short periods;
- Excellent mechanical resistance for the transport of heavy materials;
- Non-toxic and suitable for contact with food;
- Excellent resistance to chemical agents, including alcohol and petrol;
- Odorless and tasteless, it does not alter the characteristics of food;
- Possibility of sterilization with the most common methods
