What is stretch film made of?
A stretchable film typically made of polyethylene. A film that shrinks with heat and is typically made of polyethylene or polyolefin. Used to wrap palleted goods.
How many types of film stretches are there?
Broken into two main categories of Hand Stretch Film and Machine Stretch Film depending on how the product is applied the rest of the variations are focused on gauge, manufacturing and application.
How do you calculate stretch film?
Determine Stretch Film Usage
- Step 1 – Determine the amount of film used each revolution.
- Step 2 – Convert Inches of film used per revolution to ft.
- Step 3 – Multiple the number of revolutions by the amount of film used each revolution.
Is stretch film the same as cling film?
In short, the answer is yes. Yet, there is a difference between stretch film and cling film that is often presumed to be true, but not accepted universally. In many instances, stretch films can be used to wrap food containers while cling film can be applied to the food itself.
Is stretch film the same as shrink wrap?
Shrink film is used for packaging products. It shrinks to form around the shape of the products being packaged. Stretch film is used to wrap pallets of pre-packaged goods prior to shipping. Shrink film does not stretch and you cannot use it as a stretch film.
What is VCI stretch film?
VCI Stretch Film is an innovative vapor corrosion inhibiting (VCI) stretchable plastic film for banding and wrapping large metal parts in shipment or storage.
What is the strongest stretch wrap?
Ninety-gauge is considered the starting point for heavy-gauge stretch wrap, which tend to much stronger and more resistant to punctures, tears and other damage. Typically, 90-gauge film is rated for loads up to 2,600 lbs.
How does stretch film work?
Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat.
How do you calculate film microns?
For plastic film it is also commonly called gauge, and 0.01 mil = 1 gauge = 0.254 microns. Therefore, 1 mil = 25.4 microns.
How much does stretch wrap stretch?
The short answer to how much does stretch wrap stretch? Stretch film will stretch as much as your machine is designed to stretch it. 300% is not unusual – but may not be the best answer.
What is the difference between stretch film and shrink film?
Can you use a heat gun on stretch wrap?
The film can be shrunk to fit by placing the wrapped object in an automated conveyor-belt shrink tunnel or oven or by using a hand-held heat gun.
What is VCI wrapping?
What Is VCI Packaging? VCI stands for volatile corrosion inhibitor. Some chemical compounds slow down or prevent the corrosion of metals such as iron and steel; they’re known as VCIs. VCIs are used as additives to packaging materials, including paper and plastic.
What is the thickness of stretch film?
Gauge: The thickness of a plastic sheet, or in this case, stretch film. It can be measured in mils or microns. The higher the gauge mil or micron, the thicker the plastic, and the more durable the product. Typical gauges for stretch film or pallet wrap range from 63 to 80 gauge, though some lighter gauges do exist.
What gauge is 2ml?
Gauge to Mil Thickness Conversion Chart
| Gauge | Mil | Centimeter |
|---|---|---|
| 150 | 1.5 | .00381 |
| 160 | 1.6 | .00406 |
| 180 | 1.8 | .00457 |
| 200 | 2.0 | .00508 |
What is the GSM of BOPP film?
120 – 150
BOPP Gift Wrapping Plain Rolls, Thickness: 10-40 Microns, GSM: 120 – 150
| Packaging Type | Roll |
|---|---|
| Thickness | 10-40 microns |

How is film yield calculated?
To calculate the yield of a square inch of film, multiply the thickness (gauge) by the density, then divide by 27.68.
Does stretch wrap shrink when heated?
What is it? Stretch wrapping is stretchable plastic film that is wrapped around a load of products allowing it to be stretched; this elasticity holds the load tightly together. Shrink Wrapping is covered loosely around a product or load & it shrinks tightly when heat is applied.
