The Problem With Plastic Bags

Plastic bags start out as fossil fuels and end up as deadly waste in landfills and the ocean. Birds often mistake shredded plastic bags for food, filling their stomachs with toxic debris. For hungry sea turtles, it's nearly impossible to distinguish between jellyfish and floating plastic shopping bags. Fish eat thousands of tons of plastic a year, transferring it up the food chain to bigger fish and marine mammals. Microplastics are also consumed by people through food and in the air. It’s estimated that globally, people consume the equivalent of a credit card of plastic every week,1 and it’s expected that there will be more plastic than fish in the sea by .2

The fossil fuel industry plans to increase plastic production by 40% over the next decade. These oil giants are rapidly building petrochemical plants across the United States to turn fracked gas into plastic. This means more plastic in our oceans, more greenhouse gas emissions and more toxic air pollution, which exacerbates the climate crisis that often disproportionately affects communities of color.

10 Facts About Single-Use Plastic Bags

1. The world uses 5 trillion plastic bags a year.3
2. Americans use an average of 365 plastic bags per person per year. People in Denmark use an average of four plastic bags per year.4
3. It only takes about 14 plastic bags for the equivalent of the gas required to drive one mile.5
4. In about 730,000 tons of plastic bags, sacks and wraps were generated (including PS, PP, HDPE, PVC & LDPE) in the United States, but more than 87% of those items are never recycled, winding up in landfills and the ocean.6
5. About 34% of dead leatherback sea turtles have ingested plastics.7
6. The plastic typically used in bottles, bags and food containers contains chemical additives such as endocrine disruptors, which are associated with negative health effects including cancers, birth defects and immune system suppression in humans and wildlife.8
7. It takes 1,000 years for a plastic bag to degrade in a landfill. Unfortunately, the bags don't break down completely but instead photo-degrade, becoming microplastics that absorb toxins and continue to pollute the environment.9
8. Chemical leachates from plastic bags impair the growth of the world’s most important microorganisms, Prochlorococcus, a marine bacterium that provides one tenth of the world’s oxygen.10
9. There were 1.9 million grocery bags and other plastic bags collected in the International Coastal Cleanup.11
10. In California became the first state to ban plastic bags. As of March , 311 local bag ordinances have been adopted in 24 states, including Hawaii.12 As of July , 127 countries have adopted some form of legislation to regulate plastic bags.13

Ways You Can Help

1. Support the Break Free From Plastic Pollution Act, which would phase out throwaway plastics, hold the industry responsible for its waste and pause construction on new plastic-making plants. Ask your members of Congress to cosponsor this crucial bill aimed at tackling the plastic pollution crisis head on.
2. Practice waste prevention first and choose to reuse whenever possible. Make sure to always bring a reusable bag when shopping. By regularly washing your bags and drying them thoroughly, you can reuse them over and over.14
3. One company, Formosa Plastics, is trying to build a mega-polluting petrochemical plant in Louisiana that would harm a Black community, degrade wetlands, and deepen the plastic pollution crisis. Sign the petition asking President Biden to revoke Formosa Plastics’ federal permit, which is currently suspended and under reevaluation by the Army Corps of Engineers.
4. President Biden can address the plastic pollution crisis rapidly through executive action. Demand that he take bold action on plastics for our health, climate and wildlife.

What is Plastic Fabrication?

Plastic fabrication is the transformation of raw plastic materials into finished products – from household items to complex industrial components – through the use of various techniques. The versatility and adaptability of plastics make them a preferred material in a wide range of industries, including automotive, aerospace, medical, and consumer goods, so it’s important to fully understand the scope of the question, “What is plastic fabrication?” Read on to discover the different methods, finishing processes, benefits, and challenges of plastic fabrication.

Methods of Plastic Fabrication

There are numerous methods used in plastic fabrication, each suited for different applications and types of plastic. Here’s a look at the most common techniques:

Plastic Welding

Plastic welding involves joining two or more pieces of plastic together by melting the material at the contact points. This approach is often used to create airtight and watertight seals      and is common in the construction of tanks, pipes, and other large structures.

Plastic Extrusion

Extrusion involves heating plastic material until it becomes molten and then forcing it through a die to create continuous shapes like pipes, tubes, and sheets. It’s ideal for producing large volumes of consistent, uniform products.

Die Cutting

Die cutting involves cutting plastic sheets into specific shapes using a specific ‘die’ tool. It is commonly used for creating intricate patterns and shapes in materials like films, foams, and thin sheets.

Thermoforming

Thermoforming is a technique where a plastic sheet is heated until pliable, then shaped over a mold using vacuum or pressure. It’s used for packaging, automotive parts, and disposable cups.

Pultrusion

Pultrusion is a continuous process for manufacturing composite materials with constant cross-sections. It involves pulling raw materials through a heated die to create products like rods, beams, and tubing.

Vacuum Casting

Vacuum casting involves pouring liquid plastic into a mold and then using a vacuum to remove air bubbles. It’s ideal for producing small batches of parts with fine details and complex shapes.

Plastic Lamination

Lamination creates a composite material by bonding multiple layers of plastic together. This enhances the strength, durability, and appearance of the final product.

Plastic Machining

Plastic machining involves cutting, drilling, and milling plastic materials into desired shapes and sizes. It is often used for creating prototypes and custom parts with precise dimensions.

Compounding

Compounding is the blending of different types of plastics and additives to create materials with specific properties. This can include enhancing the plastic’s strength, flexibility, or resistance to heat and chemicals.

Molding

Molding involves shaping plastic by pouring or injecting it into a mold where it cools and hardens. There are several types of molding, including injection molding, blow molding, and rotational molding, each suited for different applications.

Forging

Plastic forging involves shaping plastic under high pressure and temperature, similar to metal forging. It’s used to produce strong, high-performance elements that withstand rigorous and challenging conditions.

The Two Plastic Fabrication Finishing Processes
