Polls tell us consumers want 'green' packaging without a 'green' premium. The good news: militant eco-warriors and capitalists alike agree. Reducing is the shortest route to reducing 'carbon footprint.'
Polyethylene Resin
If you’re not ready to go whole hog with biodegradable polyethylene, new polyethylene resins are stronger so they permit lightweighting, or using less plastic to get the job done.
Less plastic = less package cost
The bad news: most polyethylene extruders survive by shipping the most tonnage possible. Gauge reduction is anathema because less volume means less sales and profit.
It’s time to rethink your thinking.
- Thicker is not necessarily better. A bad or inappropriate resin for a specific application is going to be a bad actor regardless of gauge.
- Not all polyethylene resins are created equal. They range from soft, cloudy and stretchy to clear and crisp. They melt at many different temperatures
At Brentwood Plastics we thrive on new resins and extract the most performance out of every pound or kilo of resin through optimum extrusion conditions. For example, we make shrink film with the minimum amount of transverse direction shrink. This means the film doesn’t need to be as wide. A percent saved is a percent saved.

Biodegradable Film
While our Regresa® oxobiodegradable film costs a little more in terms of weight, a net savings can usually be achieved by reducing the thickness of the film / bag / packaging.
( Regresa is Spanish for “go back” or “return”. We add a food-grade catalyst which hastens the return of the natural gas-based polymer to biomass in a few years instead of several hundred. )
Whatever your agenda, we are ready to custom tailor a solution for your polyethylene packaging needs.
Brentwood Plastics is a St. Louis, MO USA based extruder of specialty blown polyethylene films since 1962.
