## BOPP Film Weight Calculator

## FAQs

**How do you calculate film weight?** Film weight can be calculated by multiplying the area of the film (in square meters) by its density (in kilograms per cubic meter) and thickness (in meters).

**How do you calculate the weight of BOPP tape?** The weight of BOPP tape can be calculated by multiplying the area of the tape (in square meters) by its density (in kilograms per cubic meter) and thickness (in meters).

**How do you calculate the yield of a BOPP film?** The yield of a BOPP film can be calculated by dividing the length of the film produced by its weight.

**What is the density of clear BOPP film?** The density of clear BOPP film is typically around 0.9 to 0.95 grams per cubic centimeter.

**What is the formula for BOPP film?** The formula for BOPP film is (C10H16O)x, indicating a polymer made from repeating units of propylene.

**What is the GSM of BOPP film?** The GSM (grams per square meter) of BOPP film typically ranges from 15 to 40 gsm.

**How many BOPP tapes come in a box?** The number of BOPP tapes in a box can vary widely depending on the size and length of the tapes. A common estimate could be around 24 to 36 rolls per box.

**How thick is BOPP tape film?** BOPP tape film thickness can range from 35 to 50 microns (0.035 to 0.05 millimeters).

**How do you calculate stretch film weight?** Stretch film weight can be calculated similarly to other films by multiplying the area of the film (in square meters) by its density (in kilograms per cubic meter) and thickness (in meters).

**How do you calculate film yield?** Film yield is calculated by dividing the length of the film produced by its weight.

**What is specific gravity of BOPP film?** The specific gravity of BOPP film is typically around 0.9 to 0.95.

**What is the size of BOPP film?** BOPP film comes in various sizes, commonly ranging from a few millimeters to several meters in width, and from tens of meters to several hundred meters in length.

**What is the difference between film and BOPP?** Film is a broad term that encompasses various materials, while BOPP (Biaxially Oriented Polypropylene) is a specific type of plastic film made from polypropylene.

**What is the formula for the density of film?** The formula for the density of film is mass divided by volume (density = mass / volume).

**What is the density of natural BOPP?** The density of natural BOPP (Biaxially Oriented Polypropylene) is similar to that of clear BOPP film, typically around 0.9 to 0.95 grams per cubic centimeter.

**How do you find weight with diameter and thickness?** To find the weight of a roll of film with given diameter and thickness, you would need to know the density of the film material. The weight can then be calculated using the formula for the volume of a cylinder (volume = π * radius^2 * height) multiplied by the density.

**How much does a roll of film weigh?** The weight of a roll of film can vary significantly depending on its size, thickness, and material. A typical roll might weigh anywhere from a few kilograms to several dozen kilograms.

**How is BOPP different from PP?** BOPP (Biaxially Oriented Polypropylene) is a specific type of polypropylene film that has been stretched in both the machine and transverse directions during production. PP (Polypropylene) is a broader term referring to the polymer itself, which can be used to make various products including BOPP film.

**How do you convert GSM to density?** GSM (grams per square meter) is a measure of mass per unit area, while density is mass per unit volume. To convert GSM to density, you would need to know the thickness of the material. Then, density can be calculated by dividing GSM by thickness.

**How many types of BOPP films are there?** There are several types of BOPP films available, including plain BOPP film, heat-sealable BOPP film, matte BOPP film, and metallized BOPP film, among others.

**How do you calculate GSM of plastic film?** GSM (grams per square meter) of plastic film can be calculated by weighing a known area of the film and dividing the weight by the area.
