Common Questions

Is Lidding Film Recyclable?

If monolayered PET or PET, yes, they are recyclable. But beyond the film’s constitution, an important missing point in the sustainability question is the lack of facilities and technologies available to recycle these materials.

We’re also seeing more and more news coverage encouraging people and companies to ditch plastic and opt for paper. but it’s not that simple.

Reconsidering Paper Bags: Unveiling Environmental Realities

Switching from plastic to paper bags might seem like a more environmentally friendly choice, but a closer examination of the data suggests otherwise.

Studies have found that paper bags involve substantially more water and energy consumption than plastic bags, adding to their environmental impact.

Furthermore, the production of paper bags generates almost four times more CO2 equivalents compared to plastic bags.

Additionally, paper bags require more energy throughout their lifecycle, including the intensive processes involved in manufacturing and recycling.

In Sri Lanka, research indicates that paper bags have a higher global warming potential than plastic due to the energy consumed during production.

This data challenges the notion that paper is a greener alternative to plastic, underscoring the complexity of making environmentally conscious packaging choices
