Plastic sheeting is not all alike, and sometimes even one small difference in that sheeting can mean failing to protect a project during construction, tools that are stored outside, and the like. When you're ready to shop for plastic sheeting, either for covering your roof while making repairs or for building a new greenhouse in the backyard, note a few tips on how to determine the right type for your needs.

Car adhesive film

The thickness of adhesive needs to be considered when choosing plastic sheeting that sticks; if you want just a light adhesive that won't peel away paint or damage delicate parts, look for auto adhesive film. This is often used by car manufacturers and repair shops to protect the car while it's moving down a factory line, being repaired or stored in a shop, or when in transit. This film needs to have a very low level of adhesive so that it doesn't peel away paint, metallic coatings, or small parts on a car when the film is removed. This makes it a good choice for covering over your own car, delicate tools being stored outdoors, hobby projects, and other such items.

Vapour barrier film

Not all plastic is made to the same specifications, so don't assume that any plastic sheeting will keep moisture away from something being stored outside or protect your roof repair work during a hot and humid day. To protect items from moisture, you want vapour barrier film. This will have a very dense type of material that won't let humidity pass through from either side. This is especially good to consider when covering something during warm and humid summer days, when moisture and humidity might collect on the item being covered and cause rust or other such corrosion and damage.

Greenhouse sheeting

Greenhouse sheeting is usually made with a type of UV barrier so that a greenhouse doesn't trap too much sunlight and cause delicate plants to wilt and wither. You may not think you need greenhouse sheeting if you're not building a greenhouse, but if you want to cover anything outside and ensure it doesn't get damaged because of exposure to sunlight, this is the right plastic to use. This sheeting is also very thick as it needs to withstand rain, snow, and other elements. It's a good choice for most of your outdoor storage and covering needs, especially if you want to cover windows on a garage or shed in order to block sunlight and insulate the interior.
