Polyethylene Vs. Polystyrene Food Packaging?

There are several reasons why you should prefer PP over Polystyrene also known as Styrofoam...

Polyethylene food container has many beneficial features and is suitable for a variety of applications. It has low strength and hardness, but has high ductility and excellent impact resistance. It stretches instead of breaking. Due to its water resistance and durability, polyethylene lasts longer when exposed to elements compared to other polymers. It goes from almost transparent to opaque, depending on the thickness of the polyethylene. The transparency of low-density polyethylene (PE) makes it suitable for packaging. PP meat trays, disposable food packaging, thermoformed microwavable meal prep containers are perfect opportunities compared to Styrofoam and other packaging methods. Polyethylene as HDPE can be recycled into other products. This is cheaper than making a new product from virgin plastic. The melting point range for polyethylene is 120-180 degrees Celsius for medium to high density polyethylene and 105-115 degrees Celsius for low density polyethylene. Due to its excellent heat resistance, it can be used at both high and low temperatures.

In contrast, environmentalists generally disapprove of EPS foam, Styrofoam, Polystyrene, products because they claim it wreaks havoc on the environment. One of the main concerns regarding EPS foam is that it`s not biodegradable and therefore takes up a lot of space in landfills, which adds to the pollution problem. If littered, EPS foam sometimes breaks into smaller pieces that are more difficult to clean up. Another argument against EPS foam is that it's made from nonrenewable fossil fuels and synthetic chemicals, which can also contribute to pollution. EPS foam sometimes makes its way into waterways and can have disastrous effects on animals that may confuse it for food or nesting material. EPS foam can be recycled, but it is often more expensive than creating a new one. Styrofoam meat trays are less resistant to heat compared the polypropylene and PET food containers. Polystyrene (EPS) is inflammable and not rigid enough to protect the food inside.
