Hefty bags, commonly made from polyethylene, primarily utilize Natural Resources such as crude oil and natural gas. These fossil fuels are processed to create the polymers that form the plastic material of the bags. Additionally, additives like colorants and stabilizers may also be derived from petroleum-based products. The production process involves extracting and refining these resources, which contributes to the environmental impact of plastic manufacturing.

Why were plastic bags invented?

Plastic bags were invented as a more convenient and durable alternative to traditional paper bags. They were originally designed to reduce the use of natural resources and provide a more cost-effective solution for carrying goods. However, their negative environmental impact has become a concern due to their non-biodegradable nature and contribution to pollution.


Scientists disagree about whether paper bags or plastic bags are less harmful to the environment. Which fact supports the opinion that plastic bags are less harmful than paper bags?

Making a paper bag uses about twice as much oil as making a plastic bag.


Is Jute a synthetic fiber or a natural fiber?

Jute is a natural fiber, often used to make manila bags or rope.


Why is ice kept in jute bags?

Ice is kept in jute bags because jute is a natural fiber that allows for breathability, helping to prevent melting by reducing condensation and maintaining a cooler environment. The bags are also durable and biodegradable, making them an eco-friendly option for storage and transport. Additionally, jute bags can absorb moisture, further helping to keep the ice intact for longer periods.


How are plastic bags made?

Plastic bags are made from polyethylene, which is derived from petrochemicals like oil or natural gas. The polyethylene is melted and extruded into thin sheets, which are then cut and sealed to form the shape of the bag. The bags are then printed with any necessary designs or labeling before being packaged and shipped for use.
