What Thickness Of Plastic Sheeting Should You Use For Your Project?

What is thicker? 4 mil or 6 mil plastic sheeting? When measuring plastic sheeting the higher the numerical value the thicker the plastic/poly.  Therefore, 6 mil is thicker than 5 mil, 4 mil and so on. Does thickener mean it’s stronger? If neither thickness of plastic has any additive or string reinforcement, thicker is stronger depending on the application.

Which plastic sheeting is STRONGER? 

A 6 mil virgin polyethylene sheet of plastic, or a 6 mil string reinforced virgin polyethylene sheet of plastic? Both films are relatively the same thickness, but the plastic with the nylon string running through it is stronger. String reinforced plastic sheeting is tear resistant and thus can stand up to wind and the elements better.

What is engineered plastic that is string reinforced?

Depending on the manufacturer, high quality polyethylene plastic is laminated together with  a layer of string reinforcement.

Common Uses For Different Thickness of Plastic Sheeting

Heavy Duty Plastic Sheeting:

Heavy Duty Plastic Sheeting- what is it? It first boils down to what job will the plastic sheeting be required to perform? A six mil reinforced film can be considered "heavy duty" when it is used to cover a desk to keep it clear of dust. That same "heavy duty sheet" would not be strong enough to line a landfill.  Understanding the strength and thickness of the film, its composition and additives and chemical make-up as well as the job it has to perform will help determine if a film is fit for the job at hand. It is critical that the film not only be assessed on its mil thickness.  For example, if the film is in the sun, it needs UV protection additives to maintain its strength.

How Long  Does Black Plastic Sheeting Last?

The average lifespan of black plastic sheeting in full sun can vary depending on various factors, including the quality of the plastic, its thickness, the intensity of sunlight, and local environmental conditions. However, as a general guideline:

1. Low-Quality Thin Plastic: Low-quality, constuction grade thin black plastic sheeting, such as standard polyethylene plastic, may last anywhere from 6 months to 2 years when exposed to direct sunlight. These materials are more susceptible to UV radiation damage and can become brittle and deteriorate relatively quickly.

2. High-Quality Plastic with UV Inhibitors:

   Sure. Here is a comparison of virgin grade polyethylene black plastic sheeting and construction grade plastic sheeting in full sun:

   Feature	Virgin Grade Polyethylene	Construction Grade Polyethylene
   Material	Made from virgin polyethylene, which is a high-quality plastic that is more resistant to UV degradation	Made from recycled polyethylene, which is less expensive but not as resistant to UV degradation
   Thickness	Typically 6 mil or thicker	Typically 4 mil or thinner
   Weight	Typically 1.5 oz/yd² or heavier	Typically 1 oz/yd² or lighter
   UV resistance	More resistant to UV degradation	Less resistant to UV degradation
   Durability	More durable and longer-lasting	Less durable and shorter-lasting
   Price	More expensive	Less expensive

   In terms of full sun, virgin grade polyethylene black plastic sheeting is the better choice. It is more resistant to UV degradation and will last longer than construction grade plastic sheeting. 

   Black plastic sheeting that is specifically designed with UV inhibitors can last significantly longer, often up to 5 to 20 years or more when exposed to full sun. The UV inhibitors help protect the material from the harmful effects of ultraviolet radiation, making it more resistant to degradation, cracking, and brittleness.

It's essential to note that these estimates are general guidelines, and actual lifespan can vary based on the specific product, local climate conditions, and how well the plastic is maintained. Additionally, factors like the angle and intensity of sunlight, temperature fluctuations, and exposure to other environmental stressors can also influence the longevity of black plastic sheeting in full sun.

Not all plastic sheeting is waterproof.

What is a good vapor retarder?

The goal of a vapor retarder is to reduce the rate at which water vapor can pass through a the plastic sheeting/liner/ vapor retarder.Putting down any sort of plastic sheeting while waterproof does not stop water vapor from passing through. Understand the perm rating of the liner before you begin your project.
