A major reason that plastic has long endured as a staple in modern manufacturing is its sheer versatility. By processing plastic into different shapes, it can have different physical properties that make it suitable for different applications.
One form factor where plastic is commonly used is flex plates. These are wide plastic sheets that are deliberately rolled to have good flexibility while maintaining an acceptable level of strength. What types of plastic are used as flexible sheets and how are they used?
arts and crafts
One has to look at industrial scale applications to realize just how useful plastic sheeting can be. If you like to do arts and crafts projects at home, you may already be using flexible plastic sheeting.
The most common example of this is printable films made of PPC (polypropylene carbonate). They can be printed with standard inkjet printers and are a great and easy way to create signs, greeting cards, documents and other promotional materials. PPC films can be made clear or matte for a unique aesthetic appeal.
Mylar film is often used to provide a protective layer to preserve artwork. Mylar is a polyester film registered by Dupont. It has excellent thermal and chemical resistance, does not break easily and does not yellow over time.
A useful property of flexible plastic sheets is that they can easily absorb an adhesive. This makes instant creation easy.stickersusing a double-sided adhesive film. Making custom stickers is not only useful for art projects, but it can also be an incredibly fun activity for kids.
Speaking of fun, one of the most engaging art pursuits is making designer pieces out of shrink wrap. Usually made of PVC, shrink wrap shrinks when exposed to high temperatures. This makes any printed or drawn piece look better due to the richer colors and better resolution.
Flexible plastic sheets are found in almost every car. They are not only aesthetic, plastic sheets are also functional.
There is a wide variety of different types of flexible plastic sheeting used in the automotive industry. Polyolefins like HDPE and PP are used to coat or laminate various automotive parts. They have good electrical properties, resist distortion when exposed to high temperatures, and have excellent chemical resistance. PP foils are generally used to cover meters due to their clarity of contact. Polyolefins are robust and easy to handle, allowing easy application to surfaces with complex geometries.
Aesthetics is of course an important thing when it comes to cars. Many of the trims and decorations normally seen on automobiles are applied to sheets of flexible plastic. There are several different ways to do this. Plastic sheeting can be printed or metallized to create a more "reflective" look.
Laser cut plastic sheets have gained popularity among car enthusiasts. With laser cutting technology, laminated plastic sheets can have very intricate designs that would be difficult to copy by hand. Almost all digital designs can be reproduced with a laser cutting machine andcnc program. Laser cutting is a very fast process that can even cut multiple sheets of plastic simultaneously.
Greenhouses are a very traditional way of using flexible plastic sheeting. Although many greenhouses today already use rigid polycarbonate walls, most still prefer the practicality of using flexible sheets, which are cheaper and can be easily removed.
Why is plastic the preferred material for greenhouses? Compared to glass, plastic has better insulating properties and allows for better heat retention. The more translucent plastic sheeting is often used in greenhouses precisely because it tends to disperse more sunlight. This results in more uniform heating in the greenhouse. There are even versions of plastic sheets that have been deliberately flooded with air bubbles to increase the diffusivity of the material.
Of course, it also helps that plastic sheets are so much cheaper than glass. Not only is the material itself expensive, but covering the plastic sheeting and cutting it to size requires a lot less work. When made thick enough, flexible plastic sheeting is durable and strong enough to withstand outdoor conditions, even in all four seasons.
Due to economics and benefits, the use of plastic greenhouse wrap has been around for decades. Most flexible plastic sheeting made today is designed to last more than ten years and can be reused year after year.
Flexible plastic sheets do not need to be clear or transparent. In interior design, printed PVC sheets provide a convenient way to add visual flair to any space. PVC sheeting is durable, customizable, inexpensive, and easy to apply.
PVC sheets are incredibly versatile. They can be printed with patterns that simulate more traditional architectural materials such as wood, leather, or marble. They can even be laminated in a way that gives them texture, giving PVC sheets a premium feel.
PVC is a naturally strong plastic that can resist wear and tear damage. Some manufacturers even enhance their PVC sheets by adding anti-UV, fire retardant, or flexibility-increasing compounds.
For clear glass interiors, a thin layer of flexible PVC sheet can help give a frosted appearance. This is perfect for private offices, conference rooms, or showers.
PVC sheets have been used as a replacement for traditional tiles or wallpaper. They come in pre-cut portions which make them very easy to make. Being inexpensive and less permanent than tile, PVC sheets are perfect for homeowners who like to repaint their homes every few years.
Medical and dental applications
In the field of healthcare, flexible plastic sheets are everywhere. They overlay the X-rays to protect the image so doctors can make charts and notes. PVC sheets are also used to cover hospital beds and pillows as they are easier to change and wash. Flexible acrylic sheets are used to make PPE such as face shields and goggles.
Plastic has some properties that make it useful in the medical industry. They are tough enough to withstand continuous use, can conform to complex geometries, can withstand temperatures required for autoclaving, provide an effective barrier against moisture and bodily fluids, and are easily washed and reused.
Unsurprisingly, a flexible plastic wrap must meet a higher set of standards to be suitable for use in a medical setting. This may include treatment with a fire retardant compound or certification that the plastic does not contain phthalates. Even with strict standards, a wide variety of plastics have been used in the medical industry for decades. These include acetate, PETG, PEEK, PVC, and polycarbonate, among a few dozen more.
how we coverin a previous article, flexible plastic sheets can be composed of many different types of plastic and reinforced with a wide range of additives. This has made them quite valuable in many industries. Plastic sheets are not only versatile, but also have excellent workability and are very economical.
Flexible plastic sheets can be printed, molded to any geometry, and withstand extreme conditions. Combine this with the additive-enhanced properties and you have another form of plastic that will undoubtedly remain relevant for years to come. We only hope that the time will come when plastic alternatives can match the utility of real plastic.
