Types of Plastic Films: Applications and Benefits

As an indispensable material for modern industry and life, plastic films are known for their versatility and wide range of applications. From packaging food and beverages to protecting medical supplies, plastic films have many advantages such as lightweight, durability, flexibility, and cost-effectiveness.

With the growing demand for efficient and sustainable packaging solutions, different types of plastic films have emerged to meet various specific needs. In this blog, we will explore different types of plastic films, their unique properties, and various applications.

What is Plastic Film?

Plastic film refers to a continuous thin plastic material, usually wound on a core or cut into thin sheets, and its thickness is usually less than 0.25 mm. It looks like an extremely clear but thin plastic bag or wrap-up. It is created from various plastic materials that are hot-stretched into thin layers.

In addition, it is a hard substance, but it is deformable and flexible. It is also transparent so that you can see through it.

Main Types of Plastic Films

There are several types of plastic film, each with its special features. Let's look at the most common ones:

• BOPP Film

Biaxially oriented polypropylene is referred to as BOPP. This is a posh term for a very powerful form of plastic film. It's stretched in two directions during making, which makes it extra strong.

BOPP film is great for printing on. Companies love it because they can easily put colorful designs and logos on it. It's also very clear, so products look good through it.

• PET Clear Film

PET film, a plastic known as polyethylene terephthalate is used to make PET film. Its clarity is outstanding and powerful. PET film is the answer when you need to see the product clearly in packaging.

This kind of  plastic film does not tear easily. It prevents moisture as well, thereby maintaining the products longer.

• Shrink Film

Shrink film is unique in the sense that it shrinks when warmed up. It is woven around commodities, like a second skin. This makes packages secure and tamper-proof.

You've probably seen shrink film on water bottles or CD cases. It protects the product and shows if someone tried to open it.

• Metallized Film

This film is metalized on one of its sides. It appears bright and metal-like. It is used on fancy packaging, which must look high-end.

Unlike regular plastic film, light and air penetration are also blocked with metallized film. This assists in keeping food fresh longer.

• Holographic Film

Holographic film creates rainbow-like effects. It changes colors when you move it around. This type of plastic film is used for special packaging and to prevent counterfeiting.

• IML Film

IML stands for In-Mold Labeling. This plastic film is used to put labels directly onto products during manufacturing. The labels become part of the product itself.

Benefits of Plastic Film

Plastic film has many advantages that make it popular:

2. The film is then cooled and wound onto large rolls. Some films get special treatments like printing or coating.

3. Quality control is important throughout the process. The film must be the right thickness and strength for its intended use.
