An Overview of Plastic Wrap
Plastic Wrap: The word “plastic wrap” refers to a wide range of materials. The term “plastic wrap” most frequently refers to food-grade plastic wrap or industrial plastic wrap used to secure pallets. Food plastic wrap is a thin plastic film that is frequently used to seal and secure food products in containers to keep them fresh. It is also referred to as cling film, food wrap, and saran wrap. Food plastic wrap is available in single rolls or, more commonly, in rolls packaged in a box with a cutting edge.

When Ralph Wiley, a lab technician at Dow Chemical, was having problems cleaning up beakers used to produce a dry cleaning solution in 1933, plastic wrap was discovered. In order to shield fighter jets from salty sea spray, the substance was first created as a spray. PVdC (polyvinylidene chloride) was the first plastic wrap to be created. Dow Chemical improved the spray and created saran plastic wrap in 1949.
Polyvinylidene chloride, or PVC, is the material most often used to make plastic wrap. Other PVC substitutes have gained popularity in recent years. Since LDPE (Low-Density Polyethylene) is thought to be safer for the body, it has been the most preferred choice in recent years. The issue with LDPE plastic wrap is that it doesn’t stick as well as PVC plastic wrap. Due of environmental worries about the chloride connected with PVC plastic wrap, the “Saran” brand switched to utilizing LDPE in 2004.
How Do You Make Plastic Wrap?
Granules of plastic are heated to a melting point.
After that, the liquid is pushed through a die to create a stretchy plastic tube.
To create a bubble, compressed air is blasted into the tubes.
The plastic is stretched into the appropriate thicknesses by the bubble.
To create a plastic film, the bubble is compressed between metal rollers.
After that, the film is rolled into a large metal roll that has the capacity to store many kilometers of film.
The plastic wrap is cut, unwound, and rerolled onto smaller rolls from the big roll.
More cling is produced by rolling and unrolling the plastic wrap.
After that, the rolls are either wrapped separately for the final consumer or put into cardboard containers with serrated edges.
Frequently Asked Questions About Plastic Wrap
What is the thickness of plastic wrap?
The majority of plastic cling wrap purchased from stores is 35 ga to 40 ga. To convert gauges into various measurement formats, refer to our gauge conversion chart.
Is it safe to microwave plastic wrap?

Does plastic wrap work well as an insulator?
No, there aren’t many characteristics of plastic wrap that make it a great insulator. Aluminum foil is a superior insulator, however it could help retain heat a little. If you need to utilize plastic wrap as an insulator, it is better to use two layers with air between them.
How may one best avoid getting cut by the cutterbox blade?
If not handled carefully, the perforated edge of aluminum foil and plastic wrap packaging can harm someone. We suggest using our Wrapmaster dispenser for plastic wrap and aluminum foil. It has a concealed cutting blade to guarantee consistently safe use.
Is Perforated Plastic Wrap available?

Can consumables be wrapped in industrial plastic wrap?
Pallet stretch film and other industrial plastic wrap shouldn’t come into direct touch with consumable goods. The FDA has not cleared industrial stretch film for direct contact with food.
Is It Possible to Heat Plastic Wrap?
It is not advisable to cook regular food plastic wrap in the oven or with other direct heat sources. According to the Saran Brands website, the brand-name wrap is safe to microwave but not oven-heat. It is not advised to heat food plastic wrap unless the product is labeled as oven or microwave safe. When heated, untreated plastic wrap can melt and emit toxins. A video comparing shrink wrap vs plastic wrap for food may be seen below. To demonstrate what happens, the plastic wrap is heated with a 1200 watt heat gun.
